Detroit Diesel 12v71 Start At OTC
taken on Feb, 16, 2011, this two stroke diesel engine sounds great. Mr. Lancaster's Class at Ohio Technical College did a great job of tuning it up. hats off to you guys!





Rap 24 hp semidiesel, second start attempt.
This video illustrates what happends when these two stroke semidiesels run out due to too much oil in the crankcase. With my left hand, I block the injection pump, so from that time the engine run on lube oil only, no diesel at all. I have heard lots of stories about this from decades ago but this is the first time, to my knowledge, that it is captured on video. Luckily we had blocked most of the air intake prior to starting and ended at somewhat over 1000 rpm. Max operating rpm is 425-450. With full air supply, I would guess this engine would reach thousands of rpm and I could only guess what would have happened then... The electric glowplug short circuited so we had to rely on the propane burner which had slightly low temperature. In this startattempt, we used an acetylene burner and got the glowplug bright red. The crankcase was, unfortunately, filled with too much oil so the engine was running on its lube oil from the crankcase instead of diesel. Still some trouble with the fuel injection, doesn't feel right when injecting diesel manually.
