In order to minimize hydraulic loss and reduce the engine load, the new CX50 Series adopts the CLSS hydraulic system, a proven technology of Komatsu construction machines. The compact 3.3-liter engine features superior performance and achieves up to 8% less fuel consumption.

The "CLSS" contributes to Low Fuel Consumption and High Productivity
The Hydraulic load is automatically detected and only the appropriate amount of oil is supplied via a variable displacement pump. This system eliminates the loss of hydraulic oil and reduces the engine load.

*A periodical check and oil replacement are necessary.
Komatsu genuine engine oil is recommended.

The diesel models feature the S4D95LE-3 engine in combination with the efficient CLSS hydraulic system, enabling them to reduce annual CO2 emissions by about 2.2 tons.
Komatsu tested data, Comparison with FD50A-7 model.
The CO2 emission coefficient is given in the Common Guidelines of the Japanese METI and MLIT (April 2006). The results may vary depending on conditions.

Low fuel consumption and low environmental impact is enabled by a 3.3-liter compact engine. The new diesel engine adopts Komatsu’s advanced technologies, a power source in demanding work places.

An electronic controlled engine with a 3-way catalytic system ensures a clean workplace.
