              Product Advantages

            • Low fuel consumption and good economy, with the fuel consumption rate in common working conditions 14-18g/kW·h better than that of competing products.
            • Excellent NVH performance, with the overall noise of the engine 2-3dBA lower than that of competing products.
            • The overall forged alloy steel crankshaft and highly strengthened bearing bush ensure high reliability and long service life.
            • Long maintenance cycle and low operation cost. The replacement cycle of the two-stage fuel filter and the oil filter both reach 500 hours.
