Lister-Petter Engines   Delta Series Industrial Engines

The DWS4 unit is a water-cooled indirect injection diesel engine built with a thin wall cast iroDWS4 Enginen crankcase with ribbing and spherical struts for strength, durability and quiet operation. It has an automotive style oil pan that allows for easier compatibility in OEM equipment. The engine also comes with an internal crankcase breather for reduced emissions and has large bearing surfaces for low bearing loads and long life. It is water-cooled by means of a water circulation pump with a thermostat that is driven by a vee belt. The cooling package is designed for ambients up to 122 degrees. The engine has an indirect injection combustion system for low vibration and low noise and the cylinder head is a cross-flow, with advanced design, for efficiency of combustion.  A full flow spin-on cartridge filter is included and the recommended oil service interval is every 250 hours.
