The advantage to building an "Ellwe" style diesel engine would be the simplicity of the design, ie: no camshaft, no timing gears, no pushroods, no rocker arms, no valves or seats, etc.
Building this style of 2-stroke would save a lot of time, both building time and design time, so that makes the Ellwe a very appealing engine design as far as using it for a prospective model design/build.
As I study and learn more about diesels, it becomes apparent that one must become a master of pumps/injectors, else the engine is not going to work correctly.
I have always understood carburetors on gasoline engines, and gasoline engines can be made to run just by spraying WD40 into the intake, even if the carburetor is completely clogged, as long as there is a little bit of compression, and as long as the ignition system is working.
Diesels rely on high compression for ignition, and so good compression is a must with a diesel, as well as an injection system that is working sufficiently well for the engine to run.
I recall my dad using starter fluid on his Detroit Diesel 671 when he would get into the higher hours of operation, and the compression would start to get on the low side.
I am not quite sure of the function of the two eccentrics; obviously one eccentric operates the fuel pump, but what does the 2nd eccentric do?
