Page 1 Principle: No of cylinders : Supercharging: Mixture cooling: Engine cooling : Lubrication : Spark plugs: Starter motor: 4-stroke Otto gas engine 6 in line Exhaust turbocharger with water-cooled turbine housing, pressure-lubricated bearings and water-cooled bearing pedestal Two-stage mixture cooling with high and low temperature cycle. Without mixture water pump the coolant circulation must be designed with external cooling water pumps with mixture temperature regulation at 50 C or 80 C Without engine water pump, coolant to be circulated by external water pump with temperature control. Pressure lubrication by gear-driven pump, exchangeable lube-oil filter in full flow and lube oil cooler integrated in engine coolant circuit. Special spark plug for industrial gas engines Pre-engaged-drive starter 24 V - 4.0 kw Starter battery capacity: 143 Ah, 24 V
