AutoElectNG:

In the meantime, Gazz.uzz deserves commendation for eating his own dog food.

For those who complain about Google and checking sources, here is a what a respected Educator and Instructor affiliated with the Oakland Institute of Automotive Technology, Oakland, California, USA said about the need to do the necessary research before working on a modern vehicle: "It is important to remember when you take on one of these newer vehicles, that you do your homework first..."

Whether that homework is by consulting Google, consulting fellow technicians, or the manufacturer's documentation is immaterial, what is material is that the technician realises that he is chasing a moving target and does his best to go after that moving target.

That is the difference between the modern automotive technician and the run-of-the-mill kind most of us run to due to economic reasons.


the genuine followers of this thread already know this

that's why the rantings of a nonentity isn't moving any one of us

we are here learning

when it's time to be petty,we will bombard his various threads and welcome ourselves on board grin

LMAO! !!

What has the bolded usually done out of your stupidities done to my progress? In case you don't know, I have been using your stupidities as driving force; you can also join timifikay and others on my thread I put its links up there to keep displaying. Thanks

I learnt this long time ago 'NO MAN IS AN ISLAND OF KNOWLEDGE ' and it changed the way I view other people thoughts n reasoning.

There is 1001 ways to learn...YouTube, self-taught, sharing in other people process etc


I have learnt many new ways to approach a subject matter ... sometimes I just sit down n shut da f$@#k up ...other times I make good use of my DATA to research more ways to learn.


U only stop learning when we die... do u know some people dey alive but dead, so new ways to learn is strange to them.

No one is saying that one should stop learning. The message is that one should stop boasting and turning him or her self to "Mr know it all" not even when you know that you consult google and the likes often like your own very gazzuzz does.

Check the screenshot of what I showed that timifakay quoted or you visit the thread, it is evidence how I displayed how ready I am to learn and to let others learn.

Get that straight! !!

Like I said b4 ... NO MAN IS AN ISLAND OF KNOWLEDGE


We like to fight where we have little or no knowledge about the war that is coming...


I know certain things now because I make use of my DATA to research things learnt here and not use the DATA to be finding who dey use YouTube or not ...

Knowledge is sharing ... knowledge doesn't boast ... knowledge that comes FREE should b embraced.

Use your DATA wisely

Oga oya make d car self work haba, 11,500 views and 17 pages and car never show green light. shocked

Uncle calm down... this is not your regular Gasoline engine... coupled with running a workshop that maintains over 10-15 cars daily, I have to squeeze out time for this project.

The end justifies the wahala involved.

By the way I am already shopping for 2 Foreign used Hybrid vehicles which I will sell here on Nairaland and Maintain.

This thread is just a stepping stone to something much bigger.

Starting and running the Vehicle efficiently is really not a large task, but I am trying to save costs (financial/Labour).

The wise already understand......


Keep calm all is in order...

That's more like it. I knew you were up to something commercial with the Hybrid.

I have closed serially at 11pm almost every day of last week, Project has been a real distraction to regular work as one of the bays is occupied with the vehicle. nevertheless as has been mentioned here on this thread, "We die here.." failure is not an option, all resources will be employed in Restoring Vehicle back to its lost glory.

The rains have not helped matters, but the cells are Gradually receiving a charge.

I will get the backup plan shortly, the backup is a 2005 toyota camry with a 2az- Fe engine, primarily to be used to start my engine to warm it up so that the Hybrid Motor will not require too many cranks before startup of my own engine.

First I will try the Hybrid battery pack 1 more time this evening to see if the charge will be enough to start the vehicle.

2az-Fxe

I pulled this from this site (google mechanic tins grin) http://m.australiancar.reviews/2AZ-FXE-engine.php

Introduction


Atkinson cycle
In a conventional Otto cycle engine, compression stroke volume and expansion stroke volume are practically identical, such that the compression ratio and expansion ratio are also identical. Hence, any attempt to increase the expansion ratio also increases the compression ratio, and hence the likelihood of engine knock or pre-ignition. Please note that:
Expansion ratio = (expansion stroke volume + combustion chamber volume)/combustion chamber volume; and,
Compression ratio = (compression stroke volume + combustion chamber volume)/combustion chamber volume.

Toyota described the 2AZ-FXE engine as having an ‘Atkinson cycle’ since the compression stroke was shortened and the expansion stroke extended. This was achieved by keeping the intake valves open during the initial stage of the compression stroke (when the piston was ascending) to allow a reverse flow of intake air into the intake manifold – this allowed for an increase in throttle valve opening in part load conditions, thereby reducing intake manifold vacuum and pumping losses. Furthermore, closure of the intake valves was delayed until the end of the expansion stroke, thereby increasing the expansion ratio. The 2AZ-FXE engine had a relatively high mechanical compression ratio of 12.5:1, but the effective ratio was slightly lower.

Since this ‘Atkinson’ operation used a smaller portion of the compression stroke to compress the intake air, it did not take in as much air as a comparable Otto cycle engine and had lower power density, yet higher thermal efficiency.
Injection and ignition
The 2AZ-FXE engine had an L-type sequential fuel injection (SFI) system which used twelve-hole injectors. The 2AZ-FXE engine had a coil-on-plug ignition system, Toyota’s ‘Direct Ignition System’ (DIS), in which the spark plug cap was integrated with the ignition coil. Furthermore, Toyota’s ‘Electronic Spark Advance’ (ESA) which selected optimal ignition timing in accordance with inputs from sensors.



2AZ-FXE block
The aluminium alloy cylinder block of the 2AZ-FXE engine had 88.5 mm bores and a 96.0 mm stroke for a capacity of 2362 cc. The 2AZ-FXE engine had cast iron liners which were manufactured so that their casting exteriors formed large, irregular surfaces (‘spiny type’) for better adhesion between the liners and the cylinder block.

Other features of the 2AZ-FXE cylinder block included:
Air passage holes in the crankshaft bearing area of the cylinder block for better air flow and reduced back pressure at the bottom of the pistons;

Water jacket spacers which suppressed water flow in the centre of the jackets and guided the coolant around the cylinder bores;
Oil filter and air conditioning compressor brackets that were integrated into the crankcase; and,
The water pump swirl chamber and thermostat housing were also integrated into the cylinder block.
Balance shafts
The 2AZ-FXE engine had twin counter rotating balance shafts that rotated twice for each rotation of the crankshaft to cancel secondary inertia forces. To cancel the inertial forces generated by the balance shaft itself, a second balance shaft rotated in the opposite direction. The drive for the no.1 balance shaft was driven via a gear on the number three crankshaft counter weight. To suppress noise and vibrations, the balance shafts were driven by resin gears.
Crankshaft, connecting rods and pistons
The 2AZ-FXE engine had a forged steel crankshaft with five journals, eight balance weights and roll-finished pin and journal fillets. The 2AZ-FXE’s crankshaft was offset by 10 mm to the thrust side of the cylinder bore centre line to reduce friction.

The connecting rods and caps were made of high-strength steel. To reduce mass, nut-less type plastic region tightening bolts and narrow connecting rod bearings were used.

The 2AZ-FXE engine had aluminium alloy pistons. While the piston head had a taper squish shape, the piston skirt was coated with resin to reduce frictional losses.
Cylinder head
The 2AZ-FXE engine had an aluminium alloy cylinder head which was mounted upon a steel-laminate type head gasket; to increase the sealing surface, a shim was used around the cylinder bore. To reduce mass, the 2AZ-FXE engine had a magnesium alloy die-cast cylinder head cover.
Camshafts
The 2AZ-FXE engine had double overhead camshafts (DOHC) that were driven by a roller chain which had an 8 mm pitch and was lubricated by an oil jet. The chain tensioner used a spring and oil pressure to maintain chain tension; it also used a ratchet type non-return mechanism.
Valves and VVT-i
The 2AZ-FXE engine had four valves per cylinder (two intake and two exhaust) that were positioned such that the included valve angle was 27.5 degrees. The intake valves each had a diameter of 34.0 mm, while exhaust valve diameter was 29.5 mm. Furthermore, the 2AZ-FXE engine used shimless type valve lifters that provided a large cam contact surface.

The 2AZ-FXE engine had valve overlap that ranged from 3 degrees to 33 degrees (a range of 30 degrees), intake duration of 280 degrees and exhaust duration of 228 degrees.
