• Product introduction

    TAS3731G Special Vehicle for the Gas Mine Earthwork:

    The dump trucks used in the natural gas deposits is a new type of environment-friendly automobile powered by natural gas engine and fueled by natural gas.

    1.   Is beneficial for environmental protection: the natural gas is clean, which makes the engine runs smoothly and lower the noise; the no heavy hydrocarbon can reduce the carbon deposition, which improve the service life of the engine and reduce the maintenance cost, meanwhile the tail gas emission is almost zero.

    2.   The dynamic property is good: the low-speed large torque can speed up quickly and make good economy, for the working condition of heavy load and long-time climbing; the volumetric efficiency at the time of raising speed improves the low speed torque and reduces the fuel consumption rate.

    3.   The economy is good: the gas consumption of 1 cubic natural gas is approximately equal to the oil consumption of 1L diesel oil, but the price of the natural gas is only 60 percent of the diesel oil, so that 30-50 percent of the fuel cost can be saved compared with the diesel vehicle of the same type.
