The engines are available with direct fuel injection. The engines can be naturally aspirated, turbocharged, or turbocharged with jacket water aftercooling. The 3306B is also available turbocharged with air-to-air aftercooling (ATAAC).A full-range hydramechanical governor controls the fuel injection pump output, maintaining the engine rpm selected by the operator. Individual injection pumps (one for each cylinder) meter and pump fuel under high pressure to injection nozzles. Automatic timing advance provides the best fuel injection timing over the full range of engine speed.The cooling system consists of: * a gear driven centrifugal pump (with one thermostat which regulates the engine coolant temperature)* an oil cooler, and* a radiator (incorporating a shunt system).The engine lubricating oil, which is both cooled and filtered, is supplied by a gear-type pump. Bypass valves provide unrestricted flow of lubrication oil to the engine parts if oil viscosity is high, or if the oil cooler or the oil filter elements become plugged.Engine efficiency, efficiency of emission controls, and engine performance depend on adherence to proper operation and maintenance recommendations. Engine performance and efficiency also depend on the use of recommended fuels and lubrication oils. Follow the recommended Maintenance Schedule found in this publication, paying attention to emission related components, air cleaner, oil, oil filter, fuel and fuel filter maintenance.
