Looking at TYM and in the sizes I need, they have essentially the same tractors but with different engines. The Yanmar is common rail, the Kukje is indirect injection. What do I need to know?
I dunno about the engines mentioned in this thread but my 40 year old Yanmar diesel engine is indirect injection.Do a network search. Diesels are direct injection. Common rail is a newer technology and generally more fuel efficient. It is normally computer controlled and can adapt more quickly to changing conditions. It also tends to run cleaner.
Yes, indirect has a little chamber.Isn't 'indirect' injection just with a pre-chamber while 'direct' has none? P-C could be a regular thing with common rail injection but may be less important with computer control than with traditional pop-off injectors. Computers will compensate for timing by more than rpm, taking load into consideration. Cleaner burn and perhaps greater economy are part of that sophistication.
