My car's engine (2ZR-FE) has offset bores so that on the power stroke the rod is vertical during most of its stroke. The rod angles more sharply as a result on the compression and exhaust strokes, but the side skirts are not under much force until the combustion event occurs and crams them into the walls. The result of the offset bore design is much lower internal friction and much less "egging" of the cylinders as wear occurs.
I don't know why, I think that it is your accent, when you said, "increased load.." I pictured the word load being spelled " LODE" This never happened to me before. It's like the articulation of that one simple word was spelled differently in my head. I don't know if that even makes a single bit of sense. But keep up the great content🎉
@@bakatzen6243 That's my point. Remove the high pressure and create a vacuum on the intake stroke and there is huge atmospheric pressure on the intake side.
He didn’t even explain it, but I saw the whole video. Basically in the video the new engine has a crank shaft that is slightly to the left compared to the bore, so it reduces the force of the piston being shoved into cylinder walls from the con rod being at a angle. Hope this helps.
@@ProjectLMZhe LITERALLY just explained something and the title says "this is what the engine gets rid off" so what does it get off? hmm oh I dont know, maybe the thing he explains in the video??
hello I had a question about a way to improve scavenging effect with some sort of an exhaust vacuum pump.how could something like this effect the engine efficiency at a relatively higher amount of compression ratio?
It would also reduce the life of the piston and connecting rod and could possibly reverse the direction of the stroke. That is why the spark plug fires just as the piston starts a downward movement.
@@williambethea8095 spark plugs actually fire before the piston reaches top dead center. its called ignition timing. Is tuned optimally depending on various factors (rpm, air fuel ratio, temperature and pressure etc etc)
@giovanniquargentan6198 Actually no. The ignition happens as the piston reaches the top. The propagation of the ignition happens on the downfall of the piston. I explained it to those who don't understand how an engine works. Fire before the top center will cause a piston to possibly go backward. All engines are timed for the piston to start on the downward as the plug fires. Otherwise, simple physics dictates what will happen. You have to replace the parts or the whole engine for one that fires before top center.

Offset piston wrist pin bores in the piston do the exact same thing.
My BMW N20 also has offset pins,I guess it's common nowadays
Yup! This channel has a twenty minute video on offset engines. Highly recommend it, I just watched it
Dang even pistons are edging now😂
Edging lmao

😂😂😂
Some engines have off set wrist pins to reduce the major thrust side.
You might want to check his other video that went into details on that
He has covered Offset cylinder design before in a long video
Tell me why they turbo the intake side of the engine. Why not suck out the exhaust with a turbo and create a vacuum for the intake???
You dont need to suck out the exhaust gas, it is high pressure. Intake on the other hand, is not.
@@bakatzen6243 That's my point. Remove the high pressure and create a vacuum on the intake stroke and there is huge atmospheric pressure on the intake side.
Thankyou for this big information. Force are more greater is the load is increased.
Thank you sir
So what does it get rid of?

@@ProjectLMZ thx
@@tidub119 no problem!

@@imnotusingmyrealname4566 what I said I meant to explain how it gets rid of it.
Can you do a video on reverse inclined engine
hello I had a question about a way to improve scavenging effect with some sort of an exhaust vacuum pump.how could something like this effect the engine efficiency at a relatively higher amount of compression ratio?
That's why yoy have to make your piston rings bigger on the load side of the piston and smaller on the other side
Wouldn’t the opposite happen when on the up?
Yes but much lesser than going down
Watch the full video about piston offset

This is why I don't rev my engine much… if at all.

Lütfen Türkçe çeviri eklensin videoyu daha detaylı anlamak istiyorum
Uzun versionu var videonun belki ordan otomatik çevrilir
tu eres hijo de Juanes????😂
