The engine pictured is an outdoor emergency standby power generator. Its located outside, in an unheated, un-insulated metal enclosure. It has to start first time, every time - no if, ands, or buts. No second chances. No glow plugs. no heated fuel, no heated air intake. It starts and achieves full power in six seconds. The engine is about three times the size of an OM617. The other day it was -14F and this thing made the 6 second start - no sweat. The block was 107F. It uses a block heater similar to the Kats unit that packerfan uses. That type of performance will not happen with a 400 watt freeze plug heater.
