In order to minimize the engine load, the new DX50 Series adopts the Komatsu's latest hydraulic system. The compact 3.3-liter engine features superior performance and achieves up to 20% less fuel consumption.
Komatsu's Latest Hydraulic System Contributes Low Fuel Consumption
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 new DX50 Series feature the SAA4D95LE-5-A engine in combination with Komatsu's efficient hydraulic system. This arrangement enables a reduction in annual CO2 emissions by about 7.2 tons.
Komatsu tested data, Comparison with FD70-8 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 are enabled by elimination of excess combustion and the use of the combined technologies of the high pressure common rail system, electronic control system, new combustion system and air to air charge air cooling system.
