Re: increasing fuel efficiency of engine

Serguei, No matter how many workshop manuals / formulaes one swallows the irrefutable fact concerning the stated 25% unburnt fuel being deposited into the Cat on both petrol and diesels cannot possibly take place for one very simple reason. The management system on both types of engines will, to pro...

Re: increasing fuel efficiency of engine

Plenty of workshop manuals being swallowed here it would appear. I have never encountered a 25 % fuel burning in a Cat. Intentionally happening. Only in the case of faulty injectors/ pintles whereby the nozzle end containing the holes has been damaged and the damaged nozzle ends gone on out the exha...

Re: increasing fuel efficiency of engine

Sleeve? Sleeve =Liner? Be interesting working out the coeffiency of friction of a rack v a Liner, less surface area on a two stroke ( ports ) v four stroke. Plus square engines different from long stroke bonkers for surface area calcs. No addendum nor dedendum calculations to be taken into considera...

Re: JS Shirase

Interesting, I can see now it's virtually at the top of its stroke it would appear.
So it's a continuous flow then and not adjusted by the rise and fall of the bow then?
So a lot of squirting wasted then?
Air models have lower ejector points perhaps?
Wonder what psi?

Re: increasing fuel efficiency of engine

We must also not forget to incorporate friction losses into all of the foregoing.
Just a thought.

Re: increasing fuel efficiency of engine

That's why, like it or not CR is here to stay for internal combustion engines.
Best all us older hands get on this CR roundabout or trail behind.
Cast adrift that is.

Re: increasing fuel efficiency of engine

Sergei,
Had a look at your video with interest, different use of a rack I have to say.
Don't know about it flying around at speed though in a crankcase.
Splash lubed?
Struggling to factor into the equation of mechanical efficiency the cost input?
Wondered if that was separate?

Re: increasing fuel efficiency of engine

Add Blue tester is off my job list then. Wonder what's next in this bid to emit fresh air only to atmosphere. Hybrid seems to be gathering pace plus loads of gas of all descriptions / types / makes / blends etc . Even human waste powered diesels are being tried over here. Image being a futuristic pl...

Re: increasing fuel efficiency of engine

And on a lot of engines with multipoint injections ( some as many as eight before, during , after and in case of injections ) that last squirt is to burn off scale/ slag / carbon buildups to reduce DPF periods. ( although the exhaust uptakes still clag up, dirty job too ) Add blue is sometimes added...
