That's the old DD 6V53 2-stroke (mostly in over-the-road 1960's semi tractors, GM/GMC Heavy Duty "Screamin' Jimmy" trucks/buses, and popular in hydraulic pump and power generators). These preceded the Series 71 and 92 applications, mostly used in transit buses, until emissions took them out of routine service in the late 90's. I do miss the sound, but not the smoke!
