ABSTRACT:
A two-stroke cycle blower charged diesel engine is adapted for compression ignition operation on methanol or other low cetane fuels by modifications primarily including means for limiting cylinder charging air to a low scavenge ratio that provides heating of the cylinder charge with exhaust residuals to a point where reliable compression ignition of injected methanol, or other, fuel occurs. Preferably, a reduced flow air supply system and a controlled blower bypass provide adequate cylinder charge temperatures for methanol autoignition. Glow plugs or other means may be included for starting and warm-up operation.
