 LPW2, 3, 4 and LPWT4 Alpha Series Engines
|
|
The LPW2, LPW3, LPW4 and LPWT4 models are water-cooled direct injection diesel engines built with rib bed 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 reduced
emissions and quiet running. The engines are water cooled by means of a water circulation pump with a thermostat that is driven by a polyvee long-life belt. The
engines also include an integrated bypass system and are designed for continuous operation in ambients up to 125 degrees. The engines have a direct injection
combustion system for easy starting and low fuel consumption and have a recommended oil change at every 250 hours.
