 LPWS2, 3, & 4 Alpha Series Industrial Engines
|
|
The LPWS2, L PWS3, and LPWS4 models are water-cooled indirect injection diesel engines
built with ribbed thin-wall cast iron crankcase for quiet operation and have extra large bearing surfaces for low bearing loads and long life. The crankcase includes a
service door for easy access and also has an internal crankcase breather for quiet running. The engines are water cooled by means of a water circulation pump with
thermostat that is driven by a polyvee long-life belt. The engines include an integrated bypass system and they are designed for continuous operation in ambients
up to 125 degrees. All of them have an indirect injection combustion system for low noise and low exhaust emmisions.
