The most common engine types - the four-cylinder, the boxer-four, straight-six, V6 and V8 - have their own pros and cons. Here's everything you need to know in one handy guide... BMW - Engineering Explained: The Pros And Cons Of Different Engine Types - Blog What makes more power, a 4.0-litre V6 engine or a 4.0-litre V8? The answer isn’t so simple. When discussing various engines, the layout isn’t the biggest contributing factor to how much power it makes. With a bit of ingenuity (and you know, cash), a four cylinder engine can make just as much power as a V12. So what makes manufacturers choose different engine layouts? Here are the advantages and disadvantages of each layout. 1. Four-cylinder inline four BMW - Engineering Explained: The Pros And Cons Of Different Engine Types - Blog Let’s start with one of the most common engines, the inline four cylinder. There’s a reason it’s common, largely because it’s so simple: one cylinder bank, one cylinder head and one valve train. Here’s all you need to know: Advantages: The four-cylinder, inline four is small and compact, meaning it easily fits in nearly any engine bay. It’s also lightweight, and with only one exhaust manifold, weight is further reduced. With only one cylinder head, there are fewer moving parts than engines with multiple cylinder banks. This means less energy is lost which reduces the probability of malfunctions. Primary forces are balanced because the outside two pistons move in the opposite direction of the inside two pistons (see picture above). Four-cylinder engines are easy to work on; the cylinder head is the highest point which makes spark plug jobs and valve train access very easy. Four-cylinder engines require lower manufacturing costs. Disadvantages: Secondary forces are not balanced, which ultimately limits the size of the engine. Inline fours will rarely exceed 2.5 litres to 3.0 litres. Larger four cylinder engines will often require balancing shafts to cancel the vibration caused by the secondary imbalance. High centre of gravity compared to some layouts (H4). Not as rigid as some layouts (V6, V8). Here’s a quick video explanation of the four-cylinder engine: 2. Horizontally-opposed BMW - Engineering Explained: The Pros And Cons Of Different Engine Types - Blog From a performance standpoint, there aren’t many options as attractive as an engine with horizontally-opposed cylinders. The boxer four isn’t nearly as common as the other engines on this list, but from an engineering standpoint it’s a logical choice for your race car. Advantages: Primary and secondary forces are well balanced. This is a smooth engine. This allows for less weight on the crankshaft, resulting in less power lost to rotational inertia. Low centre of gravity allows for better handling. Disadvantages: Packaging size: these are very wide engines. Flat engines were once used in Formula 1 for their performance advantages, but due to their width they obstructed airflow and are no longer used. Complexity - two cylinder heads/valve trains. Rocking couple (plane imbalances) due to offset pistons to allow for the connecting rods to connect with the crankshaft. Maintenance can be challenging if packaging is tight. 3. Straight-six BMW - Engineering Explained: The Pros And Cons Of Different Engine Types - Blog An engineer’s object of affection, the straight-six is the result of tacking on two more cylinders to an inline four engine. BMW loves them, and it’s the layout of one of the most well-known boost-ready engines, the 2JZ. So what’s so special about the straight-six? Advantages: The straight-six is Inherently balanced. The layout combined with its firing order leads to essentially the smoothest engine out there. V12s and Flat-12s are the next step in further reducing vibration, as they are two I6s matched together. Lower manufacturing cost - single cylinder block with all the cylinders in one orientation. Simple design, easy to work on much like the I4. Disadvantages: Packaging can be difficult due to the length. Not ideal for FWD vehicles. High center of gravity (vs flat engines). Lower rigidity than V engines as it’s long and narrow. Here’s a quick video explanation of the straight-six: 4. V6 BMW - Engineering Explained: The Pros And Cons Of Different Engine Types - Blog Now cut that straight-six in half and match the two cylinder banks to a common crank. The V6 is a common layout when there are six spark plugs involved. It’s also the current layout for Formula 1 engines. Why use it? Advantages: They’re compact and can easily be used for both FWD and RWD vehicles. Allows for greater displacement than four-cylinder engines, typically meaning more power. Rigid design. Formula 1 chose to use V6s rather than I4s for the 2014 season because they wanted to use the engine as a stressed member of the car. Disadvantages: Two cylinder heads means added cost, complexity, and weight. Additional rotational inertia and friction (more moving parts). High centre of gravity vs flat engines. Cost is often greater than inline. Secondary imbalance requires additional weight on the crankshaft. Two exhaust manifolds means additional weight. 5. V8 BMW - Engineering Explained: The Pros And Cons Of Different Engine Types - Blog When you add a cylinder to each bank of the V6, you get an icon in both American muscle and European exotics - the V8. It can produce a refined whine, or a shuddering burble. So what makes this layout such a popular choice? Advantages: Packaging size (short in length). Good balance, depending on the crankshaft type and firing order (flatplane vs crossplane). Rigid design. Allows for high displacement. Disadvantages: Like a V6, the V8 engine’s weight can be high. Additional rotational inertia and friction (more moving parts). Cost and complexity will be higher. Higher centre of gravity vs flat engines. Engine weight is usually increased. Packaging is large, typically restricted to RWD/AWD vehicles. Let us know below which engine type you are currently running and what you like and loathe about it. https://www.carthrottle.com/post/engineering-explained-the-pros-and-cons-of-different-engine-types/

ble SUV risky? Absolutely. I mean, who else does it? Jeep? Actually, yes, Jeep has the Wrangler, but that's an iconic car, nobody's going to ever raise an eyebrow in its direction. Besides, it costs almost half the price of the Evoque Convertible and that's not an easy thing to ignore. But here's the thing. The Evoque is a very, very special car - not just for Land Rover, but for the entire industry. The British pretty much revolutionized the premium compact segment with this thing in terms of how modern, and perhaps even futuristic, an SUV could look. Besides, the Wrangler and the Evoque couldn't be more different. One's a rugged, retro-looking off-road machine, while the other is a stylish, ultra-modern, premium crossover that some might call an SUV. However, both models can offer their customers a little bit of "best of both worlds" action, which for some people can be priceless, especially when they've already been drawn in by the Evoque's design. So let's run through a few of the reasons why the Range Rover Evoque Convertible is worth your money. #1 Everybody will stop and stare at you As with all new cars, the convertible version of the Evoque will draw a lot of attention to itself. It has the same design as the 5-door or the Coupe, but something just makes it completely different. Now what could that be? Ah yes, it's the fact that you can take the roof off at the push of a button! Not only will this car draw attention to itself, but it will also put you, the owner, in the spotlight. People will want to know who's behind the wheel, who had the inspiration to purchase such a car at a price that might suggest you care a lot more about style than you do about practicality. Yet that's not a bad thing necessarily. Some might even get this car as their secondary ride or simply get it as a gift for a loved one because it will always send a very strong statement. In fact, a rather unique statement. #2 Perfect for those looking to trade up from a Mini Cabrio You know that cool group of friends who get in their Mini Cabrio and just take off to spend a couple of days at the beach? If any of them (the one who does the driving anyway) decided that enough is enough as far as taking long journeys in a small car is concerned, the new Ranger Rover Evoque Convertible would literally be the perfect car for them. The reason for that is because the Evoque is already the 'Mini' of its segment, as far as style and social status is concerned. You buy it because you want it, not because you need it, and you know that it will make you look good wherever you go. Besides, it might just take a couple of years off your ID, since it's generally thought of as being a Gen-Y car. #3 Better visibility than in the regular model If you've ever driven the Evoque, you probably realize that it doesn't exactly offer the best visibility. Don't get me wrong, it never gets to the point where you just want to take it back to the dealership and set it on fire, but if you're stuck in some irregular bumper to bumper traffic and you're in constant need of changing lanes, everyone else is struggling to do the same, it's dark and it's raining...well, it can get a little stressful inside, even for experienced drivers. You end up relying a lot on the car's rear-view camera, even when on the move, though some countries are a lot more organized than others as far as what's acceptable to do in traffic and what isn't. So that scenario above only qualifies if you live in a place where people constantly cut you off, hardly ever let you merge, use the tram tracks as another lane and so on. Also, I just realized that everything I just said doesn't apply anymore if it's raining outside because you can't drive around with the top down anyway, so let's just scribble out the rain part shall we? Thanks. #4 It may just be the coolest SUV in the world It's important to point out that the Evoque Convertible is the only premium SUV in the world which you can take to any type of destination (mountains, beach) and it will be equally at home and equally useful to you regardless of where you are. You can't exactly drop the top off your BMW X3 while cruising in the sun, can you? Can't take a short drive towards that awesome skiing resort with the top down in a Mercedes GLC either, right? And when you're done with all that, you can park it in front of any luxury restaurant, country club or night club and nobody's going to scoff at it. Bottom line, there's just no substituting the Evoque Convertible with anything. And you can't say Wrangler because that's not a premium product and it doesn't make this type of stylish statement. So what you end up with is a one of a kind type of car, and that's going to mean the world to its future owners.

omoelesa:You seems bitter Why Are u bitter at Igbo saying they wanna go Or bitter at nnamdi KANU Of bitter that you a Yoruba can't stand on your own Or bitter that you are not Igbo I just don't get your ranting and other yorubas These set of people said they do not want your association again is that a big thing . why are you guys so bitter as if it is your end of the world So without Igbo can't you guys survive Just take time and read all your post |
juicee1:What happened to the inspiration of the Yoruba political skills in |
ojuolu:And you in your irrational thinking is understanding him OK na |
Cars overheat most often in very hot weather. We are in a hot humid place and this harnattan wont laygh It’s rare with modern vehicles, but even a well-tuned automobile can overheat. If you find yourself in stop-and-go traffic or climbing a steep grade on an extremely hot day, and your dashboard temperature indicator starts to rise or a malfunction indicator light comes on, here’s how to help your vehicle regain its cool: At the first sign of overheating, shut off your air conditioner and open your windows: Doing so decreases the load on the engine and helps it cool off. If you continue to overheat, turn on the heater and blower: Doing so transfers the heat from the engine to the passenger compartment of the vehicle. (This does wonders for your overheated engine but very little for you!) If you’re stopped in traffic and the temperature gauge is rising, shift into Neutral or Park and rev the engine a little: Doing so makes the water pump and the fan speed up, which draws more liquid and air through the radiator. The increased air and liquid circulation helps cool things off. Try not to ride your brakes: In stop-and-go traffic, crawl along slowly, on little more than an idle, rather than moving up and then braking repeatedly. Brake drag increases the load on the engine and makes it heat up. If traffic is crawling, move up only when the gap between you and the vehicle in front of you gets too large. If you think that your vehicle is about to boil over, drive to the right-hand side of the road, open the hood, and sit there until things cool off. Remember, don’t open the radiator cap under these circumstances, and if your engine has boiled over, don’t add water until the engine is quite cool again. If you must add water when the engine is still a little warm, add the water slowly while the engine is running in Neutral or Park. Although hot weather is the most common cause of overheating, many other factors can cause the same problem. If your vehicle overheats in traffic in normal weather, one of the following may be the culprit: The water and coolant level in the radiator is low. There’s a leak in the cooling system. If you can’t locate any leaks, your thermostat may be malfunctioning. Obviously, you can’t replace the thermostat at the side of the road. In the meantime, if you can park and get to the thermostat safely, you can eliminate this malfunction as a possibility. Wait until the engine cools down completely, and remove the old thermostat and reconnect the hoses without it. If the engine starts up and runs well without the thermostat, the old one was probably screwing up the works. Get a new thermostat immediately if you find that your old one isn’t working. Driving for long distances without a thermostat can damage your engine. Some other school of thought also believe in tropicalization of cars if you are in hot and humid places like Africa . This might cause rich burning if there is anything like this but at least rest of mind is gguaranteed. If you can't tropicalise the engine please get a new thermo The choice is all yours and the weather is all getting hotter |
kkulaja:You have masters this act..my clutch has failed once that was years ago..my gears are smooth ...but how did you masters this seamless transmissions I am interested. I am a manual buff |
Adesiji77:Is that pastor God that will know if she is in heaven or is he Peter's that has the keys to hevaen All these pentecostal pastors seff |
ghostmist:You don't know these people ....they are so shameless . I wonder what and how they behave I have seen that their Yoruba commonwealth thread and the abuses they abuse us ..yet I did not comment That to me is dignity and self respect but look at them here How can we continue to dwell with such a people that has lost all sense of dignity It's pathetic and despicable to say the least This is just an Igbo thread Can't people see that ? |
juicee1:Oga i domt want to derail this thread . I live in Lagos and I have also stayed in ota ..I was at akure some weeks ago I know south west like the back of my hand ..I was at futa so you can tell those lies to those that don't know these places not me Tell me which town in west that can compare with Onitsha and Enugu with Owerri ..let's take away Lagos |
juicee1:I know that Yoruba will take the credit. Just in few years time gwari will take the credit of Abuja If yorubas are that good in building cities ...what happened to Ibadan ,ota,ife with their history and other forlon Yoruba cities . So r u saying that immigrants never contributed to Lagos or did they use cocoa to build 3rd mainland bridge Try to be appreciative Replicate your so called skills in Ibadan and ife and other rustic towns like ota, okitipupa et Jos and kaduna are not developed at least I know those places well and they can't be compared in economic viability with Onitsha or aba and in terms of planning with Enugu Tell me apart from Lagos which Yoruba town can be compared with even Owerri and Onitsha not to talk of Enugu ..dude your detailing this thrrad |
juicee1:Lies dee Sam did more |
cheruv: |
juicee1:Who is this ? Why did awo not develop okitipupa, ife and other places like ota |
Eddygourdo:The advantage of Lagos is just government ...this is what I said ab initio the exclusive list which is sea port , international airport and federal capital ...this made Lagos what it is . and also mind you the systematic killing of other ports As you can see it is not Igbo fault But once their is self governance then Igbo can chart their course as of now Igbo hands and feets are tied |
Eddygourdo:Your correct It's not our making we don't have sea port remember that's its in fg exclusive list Our hands and feet are tied here The first region that built its airport solely without fg was IMO state and the first state university same imo The east did self electrification via communal efforts what other regions are still trying to grasps These feats was like 30 yrs ago So what other human capacity are we talking here nwanne |
Eddygourdo:Define the current state of south east in comparison with let's say Northwest or south west excluding Lagos or maybe arid California |
Eddygourdo:Necessity is the mother of invention What makes you fee we cant sustain ourselves We have like 30 million peeps which is bigger than most countries and half of British population Give me reasons why we can't be self sustaining One thing is that when you feed someone r so long the person will be scared to stay on his own This is your theory Principle of comfort zone |
I think the black man should start thinking for him self. He has been used for centuries |
Eddygourdo:Let me tell you The greatest resources one have is human capacity and God has blessed Igbo so much on that . just that we need resourceful people I am from anambra and I can say that I have seen ingenuity in aba and nnewi The Biafra war was an eye opener also The gods can't do for a man what a man will do for himslef Switzerland Singapore and Luxembourg don't have any resources but their brains This over depending on oil is killing me |
Eddygourdo:What makes you think Nigeria will be more prosperous Just take a cusory look at south east states and other states Then compare |
Eddygourdo:Because you don't know the meaning Pls thank me for the lectures Iwe GI juo oyi nwanne madu |
IGBOSON1:I keep on saying it Nigeria sucks and can't or won't develop U made a very valid point Do mind me sending you nkwu enu? |
Eddygourdo:You see I said that You don't know the meaning of Dutch disease ...now let me lecture you It is not a curse word It is a situation where nations that have oil depend so much on oil that they can't think outof the box Can you pls Google it . this how to learn So you can see your not an authority here |
ArodeTsolaye:That's the problem I have with blacks ..we don't reason What is big ..Igbo said they are done Is that complicated .... |
Eddygourdo:Explain your economic viability ..maybe this Dutch disease has affected all of you I doubt you know the meaning of Dutch disease |
TonyeBarcanista:This ijo dude ...who are the ss that said that .my position and most Igbo position is stay away from ijo and edo peeps Now go and fish This is Igbo thread Or are you now Igbo wanna be I don't have kaikai |
EUROBOMBER:To me it is pointless I feel the feeling should be mutual |
