M318C^Non-Current

3056E ATAAC Engine

The Caterpillar 3056E ATAAC turbocharged engine is built for power and meets all current worldwide emissions standards. The air-to-air aftercooler reduces smoke and emissions by providing a cooler inlet air for more efficient combustion. This also extends the life of the piston rings and cylinder bores.

Service

The engine is longitudinally mounted on the right side for easier servicing of the oil filter, oil filler, oil drain valve, fuel filter, V-belt tightener and the oil dipstick. All are accessible from ground level. The radiator and hydraulic oil cooler fan and air conditioner condenser are hinged for easier cleaning.

Cooling System

The cooling system features an electronically controlled variable speed on-demand fan. The fan is driven by a hydraulic pump. Fan speed is determined by engine coolant, transmission oil, hydraulic oil and inlet manifold temperatures. Cooler operating conditions allow lower average fan speeds resulting in reduced fuel consumption and lower noise levels. The electronic engine control continuously compensates for this varying fan load providing consistent net horsepower, regardless of operating conditions.
