These engines pull natural gas compressors on a pipeline. Some are in generator service(1200 KW) and some are on big tug boats. They are dual fuel...meaning they will run on natural gas or diesel. Most gas engines are spark ignition but some use a tiny bit of diesel(10%) for ignition. The engine weighs approx 180,000#. The crankshaft weighs about 22,000# and the flywheel weighs in at around12,000#. I bent the rod in 1975 when I attempted to start the engine and water had leaked on top of the piston forming a liquid lock. It broke the piston and cylinder liner and bent the rod. Just those three parts back then were 30,000 dollars. The rod cost 18,000. I guess you could say I am a knuckle dragging mechanic!!
