Yet..... Another Stupid Question From The Stupid Question Master.....

Introducing the... ...



DIESEL HEMI



Whats makes a hemi a hemi ????



To my understanding its just the fact that it has hemisperical heads . ?. ?. ?...



Right????



If so why could'nt there be a diesel motor with hemisperical heads ???

I should get paid for this

They also have the vaves canted and rotated 1/4 turn so that the intake is next to the intake manifold and the exhaust is next to the exhaust manifold. I don't know how a domed piston to fit the domed head would work for a diesel? Jake

Exactly what I was thinking Jake! Domed pistons... now theres one for the books! :-laf :-laf :-laf It could be workable... just need the compression ratio.



Could always just make up emblems and put em on anyway. At least we'll be half-correct and since nobody seems to have any brains anymore, we'll probably get away with it for a long time! Oo. Oo. Oo.

That's not a dumb question.



Dumb would be someone ordering the Hemi... . paying extra for the Hemi... . bragging about having a Hemi..... And when asked what that is exactly, they don't have a clue. ???????

Spark plugs: Just say NO! Oo.

A hemi shaped combustion chamber diesel, although possible is not practical. The flame front would have to travel a large distance to reach all of the fuel in the head. Almost all diesel engines have a flat cylinder head surface with the combustion chamber in the piston. The Cummins engine with the centered injector creates a swirl that burns all of the injected fuel. The biggest advantage would be in breathing, but at the relatively low speeds of a diesel and high turbo pressures pretty much eliminate that advantage.

By the way, Toyota makes an engine similar to the new dodge "hemi" engine. Their engine also shares the spark plug in head design, hemispherically shaped head and flat piston. They don't call it a hemi because it is not one. Dodge has been lying to it's customer. A real hemi has a domed piston. New ones have flat top. Go figure, typical dodge lies

I guess the last thirty-five years that I have been running Chrysler engines in my race cars I haven't been running hemis. Almost all of them used used flat top pistons. How else are you going to lower the compression to handle 90% nitro, and a blower. The shape of the piston has nothing to do with whether it is a hemi or not it is all in the shape of the cylinder head. The reason Toyota doesn't call their engine a hemi is the copyright owned by Chrysler. Daimler (England) also built engines that looked like small hemis. (2500cc)

See that is totally for a different application. You must drop the compression on the engine so the only way to do that is get rid of the domed piston. The original hemis have domed pistons, why don't the new ones have them? It does not deserve the name "hemi". Your right, toyota can't use the name since it is a trademark but you don't even see them advertising the spark plug in the middle and hemi style cylinder head. Why? They don't have to since their overall fit and finish of their truck is more to talk about above the engine, Dodge makes a crappy product overall and all they can talk about is the new hemi to get people excited from hearing stories of the old 60's hemi equipped muscle cars. The people that buy the news hemis are the ones that say dude its got a hemi acting like they are the same engine they were over 30 years ago when thats false. Dual spark plugs, coil packs, multiple sensors, overcomplication much???
