Caroilne Diesel Engine
Heads

Now that I will use the WV 1.9 piston it has a recess built in to it and as such the Junk Head need not have a recess. Therefore the junk head will be flat or will have a hump that protrudes in to the piston cavity.


Here is a basic idea of a swirl chamber.
Only it will be in the Junk head.

With a normal small engine a swirl chamber is required to improve efficiency, but with valves in head the chamber is offset, and this is not ideal.

With this engine the swirl chamber is in the centre with the injector in the centre as well. This should give a better swirl and fuel burn..

combustion chamber in conventunal 2 stroke valved head.



note the hot valves. this will not be there in the sleeve valve engine. this is not realy a problem in a Diesel but will be for precombustion in a petrol engine.
