Please let's talk about the advantage and disadvantage of both, someone has already convinced me the carburetor is a better technology than the injector in Nigerian environment.

As if you don't know.....

Isn't that obvious? Do you really think if 95% of cars on Nigerian roads are fuel carburetted, that this Car Talk would have been created or existed? Out of the 1st 30 topics on the 1st page of this section, how many are not "Help!" related? Even on topics that have nothing to with car issues, someone must jump and cut in with "Help! My car is killing me o!" Lol!

I mean, who has never posted "Help me o!" In this section? Even me sef! Check my starting posts and topics when I joined Nairaland. Help everywhere. Lol! Why all the help? EFI system has made almost everyone's 2nd user name on online forums "Help!"

If a fuel carbureted engine starts misfiring or rough idling, you simply check distributor cap for crack, check spark plugs leads for leaks, check condenser on distributor for burn, check spark plugs or the contact point in the distributor or simply wash the carburetor. You must find the culprit among these above.

But for EFI, wahala! Even with exam made easy called "Scan tool", some faults would be hidden in some sensors or injection components such that it will take serious manual troubleshooting to detect the culprit. With the carburetted engine, fuel pump failure is easier to tell when it happens. You don't need to be technical to know that. But for EFI, it gives similar symptoms other injection components give when it starts failing, unless the person has an expensive pressure tester to detect that.

A misfire in EFI system could send you to TB Joshua to find the culprit. But for carburetted engine, even a dumb will tell you the culprit.

What about the emission system on EFI. Lets not even go there. Bank 1 sensor this and this and Bank 2 sensor this and this. Bank 1 pre-cat and bank 2 pre-cat. As if that's enough, main catalyst still dey there. They even put sensors to monitor these catalytic converters. What about EGR valve?

We are simply not making it easy with these EFI cars for our poor Nigerian mechanics. They have no option than to be performing Circus on our engine bays.

Before you tell me fuel economy is better with EFI systems. No doubt about that. But lets not forget few decades ago, Peugeot 604 V6 averaged 20 mpg doing 180 km/h. Now, how many cars on Nigerian road today can give you upto that economy at simple 100 km/h, with their terrible state of their injection systems? You know, Nigerians said "No" to diesel cars. Unfortunately, our roads says otherwise. Because the amount of black smoke that discolor atmosphere on roads is baffling. If all these black smoke coming from petrol EFI cars, imagine what our roads would look like when Nigerians switch to diesel cars, considering this semi-diesels we have here and call diesel?

By all ramifications, Nigerians are not yet ready for EFI cars. But then, we cant do without them.

Thank you Mr Ikenna as usual for the clarification, I thought the guy must be high on something, but seriously are this car manufacturers something else, if the carburetor is better than the injector, why the change from easily diagnosable to professional diagnosis?

Just look at it this way. A CRT TV vs LED. CRT is easy to set up, cheaper and easy to troubleshoot. A part can go wrong and an electrician only needs to change the failed part and voila its back on. I even remember my fathers old TV, whenever it misbehaves all we have to do was hit it at the top and it will correct itself. Inside there are several ic's and other replaceable parts.

Now look at modern LED TVs, made up of just one panel. They are thinner and u can hardly find anything to replace in them. But would u use an old CRT TV just because they are easier to fix? I doubt it. LEDs give better picture and are energy efficient. U can still operate ur TV at current as low as 100 volts, good luck watching ur CRT with even 200 volt .

Injector engines are more efficient than caburators, though they are more difficult to troubleshoot. It is a lot easier to build a fuel efficient v8 car with injector, something that is not possible with a caburator engine. Fuel injection meters the fuel much more precisely than the carburetor.

With a carbureted car, you could not just start a cold engine and drive off and expect it to run right, especially in cold weather. If you didn't finesse the throttle, these engines were easy to stall. A modern fuel injected 4 cylinder car would run circles around a caburated v6 car.

Whoever thinks caburator is better than injector, let him go and convert his fuel injected engine to caburator and come and tell us the result.

And that pretty much sums it up.

Only someone totally automotive inept and technologically clueless on what it takes and access to the required tools to properly work on modern automotive systems would prefer a carbed engine over a fuel injected one.

The sorts of power that we make with small displacement engines these days required big V8 engines with carburetor in the old days. And God help you if your high horsepower carved engine burps or a pebble gets sucked into your carburetors primary jets = grenade of your engine due to wrong AF ratio.

You never have to adjust for altitude changes now with carved engines, you never have to adjust for bad gas, you never have to adjust for bad timing, etc

I think the issue here is that many of these guys are cheap and some of the dealers are crooked, they go our there and preorder a POS junkyard crapola and polish it up and so of course when that hits Nigeria the dashboard gauges lights up like a xmas tree.

When you have the proper tools, the proper know how, a modern fuel injected car is uber easy to work on, way easier than a carbonated one.

As usual your mileage may vary.

PS: OH yes, Nigeria is not on Mars, it;s right here on earth, there are similar climates to Nigeria in the USA. I have off road vehicles which sees much more rough roads and extreme conditions than you see in Nigeria or at least similar and they soldier on.

For any one that owns a modern Volkswagen or Audi product this is a required reading at your leisure. Bonus if you used to have older products from the same marques.

Ok I guess we should embrace technological advancement but if I were to travel a long distance with the intention of reliability and ease of diagnosis, I think a carburetor powered car will be my choice among my fleet, why I can easily open it up trouble shoot and be on my way.

After all carburetor powered cars in those days must have a good fuel economy then as Mr Ikenna rightly gave an example.
This is a basis for comparism people not to start a war or take us back to carb age.

Carb cars of those days are less fuel efficient and slower than fuel injected cars. Today it is easy to see a 2.4L i4 engine doing 200hp. That is not easy to achieve in carburated cars. It requires big displacement engines yo get that amount of HP.

Ok, the basis is Nigerians want something easy to maintain and takes abuse easily I would call it "manage" something that when spoilt or nearly dead, maggic can be worked on it and it picksup again reason for some hard headed drivers thinking manual tranny is more fuel efficient than auto tranny
But if we look at the carburetor it is one thing I am amazed at especially when I see the BEDFORDS carburetor with a camp-fire. The carburetor was built to last and last and last.

nurey: Please let's talk about the advantage and disadvantage of both, someone has already convinced me the carburetor is a better technology than the injector in Nigerian environment .

Lack of understanding of questions is why people fail exams.

Excellent.

It's getting easier for me to sort out through the folks on here who are reasonable in an automotive sense .

Kudos.

PS: It also matters less where you are be it Nigeria, Alabama or Timbuktu. You simply can't trouble shoot a modern engine like the old days.

Certain people are stuck in there ways and fail to realize and give due credit to fantastic mechanics in Nigeria who works dutifully and intelligently on modern cars and who equipped themselves with the necessary automobile tools required to service modern cars.
