I am Jonesing for a small, air-cooled diesel engine. I don't have any good reason that I can articulate. It seems like there are a dozen potential uses for a prime-mover: Pumping water, turning a generator, powering a rototiller and so on.
The sizes that are available are 196cc and 3hp, 247cc and 5hp and 406cc and 8hp.
|Running at its most efficient RPM (2700) it produces 5.5hp and will consume about 1.05 liters of fuel. Said another way, a gallon of diesel will last 3.6 hours at that operating point.|
Fuel economy is pretty good.
A Chinesium diesel engine is twice as expensive as a comparable gas engine. I am not sure why I want one, but I do.
I asked an internet friend if I should buy one. He was horrified and answered "Absolutely not. You should buy two of them"
Any opinions? I am leaning toward the 247cc, 5hp model for $350 bucks, delivered.
