MT07 Natural Gas Engine
SINOTRUK MT07 gas engine was collabratively designed an developed with Econtrols from the United States, based on MC07 diesel engine. Utilizing LNG and CNG as fuel, a new generation engine of high quality energy saving and environmental protection. MT07 engine meets on-road National Ⅵ（Euro Ⅵ） emission regulations, with an ultra-long drain interval of 30,000 kilometers or 6 months , Has significant advantages such as high reliability, strong performance, low gas consumption and low noise.
Product Features:
Four valve structure design effectively improves the charging efficiency, the central placement of the spark plug effectively improves the flame propagation speed, Econtrols new generation CFV gas supply system ensures continues and accurate gas input, the equivalent combustion method makes the power more sufficient, effectively improving the inherent low speed torque defect in gas engines and enhancing power performance, reducing gas consumption , the engine economy is further improved.
Iridium electrode spark plugs significantly increases the service life.
Electronically controlled pressure regulating intake + EGR: Achieving equivalent combustion, guarantee the low gas consumption and high thermal efficiency.
Air-fuel ratio is controlled by wide domain oxygen sensor to ensure economic and emission compliance.
All condition closed-loop control to achieve the optimal combustion.
