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