The ART of the Engine Out Service: Engine Outs Not Created Equal

Great attention to detail. Showcase for them obviously.
I hope the previous guy servicing that car has moved on to something where he can do less harm.

 

Very clever cradle set up, and superb attention to detail.

 

Wish I could read Japanese. Pics do speak for themselves. The previous service was junk for sure and I think that is 75% of the problem with these cars.

Very nice pics and work but they are talking about altering valve timing at different load ranges and rpm via the variable valve timing mechanism?

Seems odd with someone with that attention to detail would make a reference to a system that doesn't exist on this car.


"We incorporate our own know-how and set up valve timing.

By changing the valve timing, you can change the characteristics of the engine.

Even if the valve tie is changed, the time to open the valve is the same for the same cam angle.

It is a setup to set up the time at which timing to operate.

The advantage of the original valve timing setup is that the overlap amount is made smaller in the idling region and the light load region, and the combustion gas blowback on the intake side is reduced.

As a result, the rotation speed in the idle range is stabilized, and the fuel consumption rate is improved. Moreover, in the light load region, the stability of the engine is secured.

In the medium load region, the overlap amount is increased, the combustion temperature is lowered, and NOx in the exhaust gas is reduced. In addition, unburnt gas is reburned and HC is also reduced.

In the high load low and medium speed rotation region, the closing timing of the intake valve is made earlier, and the low and medium speed torque is improved.

In the high-load high-speed rotation region, the closing timing of the intake valve is delayed, and the maximum output is improved.

At low temperatures, the overlap amount is minimized to prevent burning of combustion gas to the intake side. As a result, while increasing the fuel consumption rate, the first idle speed is stabilized.

When starting the engine and stopping the engine, minimize the overlap amount and prevent the combustion gas from blowing back to the intake side. This will improve startability.

The variable valve timing mechanism works very complicatedly."

 

Nice work and documentation. I'd love to see the translation.

 

Surprised to see them install the belt fences - I did not think they were typically used?

Very nice detail.

If a little RTV is good, a lot is better, amirite?

Using google translate you can copy paste the text and get a decent translation.

The paragraphs I translated are generic comments, not detailed tech procedures.

Early cars had, but may have been discarded. Part #23 and 29. 96 on didn't. Don't know when they actually stopped installing them.

Yes, but Bing translates the entire web page. It's an add on for the browser. I just right click anywhere on the web page and select Translate with Bing and select the languages of let it auto detect.

 

Yes, I'm aware of that John as I considered putting them on my 95 B but it seems nobody is using them at all anymore. Hmmmm.....what to do?.........

 

They are gone off my car too. But I which it had them. When I pull the plug coves I'm always worried abut a screw falling in there and getting caught.

 

If available, they are not expensive to I will get a set. whether or not I install them is another story

 

And the cars that do have it have nowhere near the control sophistication to do what they are describing.

 

Never came on US cars in much the same way they were market dependent on the 308 QV.

In practice it has never really been shown one way or the other to prevent debris problems. One thing we do know about them is when debris gets in the belt area the covers do a good job of keeping it there. On the QV and later cars I know the man responsible for them and as hard as it is to believe his intention was to prevent the drifting snow from packing the inside of the belt cover. Evidently it was a real problem when the cars sat outside in the winter at the port in N.J.

 

That's a neat piece of trivia.

 

My QV has them. I head the "snow story" when I bought my car back in 85 from Stan Nowak. To paraphrase, "Water/snow get's into the belts and freezes. When you start the car the belts break...."

 

Most QV's do. Glad someone else heard that story, people look at you funny when you say it was to protect from snow. Like I said, I know the guy who made the decision.

 

Makes a lot of sense from the snowy perspective, that stuff packs into wheelwells like no tomorrow

 

I could not finish reading the entire thing. I concluded that it was too much foreplay, not enough sex.

 

Easier if you just select translate page when you are in Internet Explorer. Page will be reloaded in English. Works great.

 

Chrome gives you a translate option too.

I see the rear bumper cover and mufflers remained in place. I thought they always had to come out.

If not, why do many people go to the trouble of removing them?

 

Because it's no trouble and affords additional clearance to access other areas.
