Product Feature

Power train

Use ACERT® Technology of Caterpillar C15 Engine

Caterpillar CThe 15 engine is a version of the proven Cat 3406 engine with increased displacement。 C15 Engine Conforms to U.S. EPA Tier 3/EU Stage III Standard,Add 3 to the original 3406.5% Horsepower。 Four-stroke engines offer high fuel economy in most applications、Durability and reliability。 Higher torque increase rate improves performance,Allows you to operate with greater rimpull、Lifting power and faster operating cycles。 Flexible engine mount reduces vibration and noise。

Engine lubrication

The engine lubricating oil is filtered by a gear pump、Cooling and providing。

Mechatronic unit injector (MEUI™)

MEUI It's a high pressure、Direct injection fuel system,No adjustment is required in actual use.。 It electronically monitors driver and sensor inputs,Achieve optimum engine performance。

Air-to-air aftercooler (ATAAC) System

ATAAC The system provides a separate cooling system for the air in the intake manifold。 It sends the hot compressed air from the turbine to a single-pass, air-cooled aluminum heat exchanger for cooling。 The cooled compressed air greatly reduces exhaust emission,In line with the United States EPA Tier 3/EU Stage III Request。 The air flow matches the power rating of the turbocharger,Reduce the exhaust emission。 Increased by 19% The bearing surfaces allow the engine to operate at maximum cylinder pressure。Greater cylinder pressure can help reduce fuel consumption、Improve high altitude operations and reduce emissions。 Cylinder Heat Drain Bushing Reduces Heat Removal,The heat transfer to the cooling water jacket is reduced,Thereby providing a greater rate of torque increase.。

The next generation of modular coolers (NGMR)

Use standard six cores(Use seven cores in machines with high ambient temperatures)Parallel flow system to improve cooling capacity。 As there is no top coolant tank to be removed,More convenient maintenance。 NGMR Use of copper tubes and blades。
