Fun gas high horsepower China National Heavy Duty MT13 engine
At the 2015 Shanghai Auto Show, China National Heavy Duty Truck MT13 natural gas engine officially unveiled. This engine is currently the largest displacement natural gas engine produced by China National Heavy Duty Truck. Its power covers 262-313kW, and it can output a maximum torque of 1900N.m at 1100-1400r/min. It is understood that compared with traditional competitive natural gas engines, the MT13 natural gas engine not only excels in displacement and power, but also its biggest bright spot lies in the latest natural gas engine ECU control system adopted by Econtrol Inc. of the United States and China. The unique vermicular cast iron material for heavy duty engines. What breakthrough could these two new technologies bring to CNHTC's MT13 natural gas engine? The China Truck Network reporter announced for you. CFV electronic control gas system is economical, environmentally friendly and stable According to the CNHTC technical personnel on site, CNHTC's natural gas engine ECU control system used in the MT13 natural gas engine is a CFV (continuous flow) electronically controlled gas system produced by Econtrol, which makes the MT13 natural gas engine in the gas economy. Sex, environmental protection, and smooth operation have performed very well. In terms of fuel combustion, the CFV electronically controlled gas system allows natural gas engines to achieve lean burn. The lean combustion can not only increase the combustion thermal efficiency of natural gas by about 15% compared with the conventional combustion process, but also reduce the internal combustion temperature of the engine by more than 100°C. This not only enables the MT13 natural gas engine to achieve the same output power as competing products with less fuel consumption during operation, but also effectively extends the service life of the oil and reduces NOx emissions due to lower combustion temperatures. This will improve the economics, reliability and emissions of the MT13 natural gas engine. Not only that, the fuel will also be independently controlled by the CFV valve, using a continuous flow supply: After the CFV valve receives the fuel supply command value from the engine computer, it will adjust the fuel mass flow by continuously changing the outlet pressure and the position of the valve core, and finally Makes the actual fuel quality reach the engine computer's command value. In this process, the CFV will continuously correct the air supply according to the air supply pressure, temperature, and other data information, so that the gas flow will continuously change. The continuously changing gas supply will cause the fuel of the MT13 natural gas engine to be evenly distributed to each cylinder from the engine intake manifold. This can effectively reduce the engine vibration caused by uneven fuel supply between individual cylinders, single cylinder knocking, etc. . Vermicular graphite cast iron materials are wear-resistant, light-weight, and high-strength Compared with the conventional gray cast iron cylinder material, vermicular graphite cast iron has better mechanical properties. Apart from the properties of common cast iron, such as lubrication and shock absorption, it has been applied to the engine body in terms of wear resistance, light weight and overall strength. improve. The good wear resistance can improve the reliability of the engine, not only can increase the first overhaul mileage of the engine, but also make the B10 life of the MT13 natural gas engine reach 1.5 million km, effectively reducing the user's use and maintenance costs. Because the same volume of vermicular graphite cast iron is only half the mass of conventional grey cast iron and its tensile strength is about twice that of ordinary cast iron, it is more suitable for parts such as cylinder blocks and cylinder heads of large diesel engines. This is also the main reason why China National Heavy Duty Truck MT13's maximum compression ratio can achieve 11.5 and the weight of the machine is only 795kg. As high-powered engines have gradually become a trend in the use of commercial vehicles and China’s commercial vehicle industry is paying more attention to natural gas fuels, how can an engine company increase the compression ratio of natural gas fuels and produce high-intensity, low-weight high-powered engines? It will be particularly important in the future market competition. China National Heavy Duty Truck Corporation has begun to follow the market closely and proved to us by using the MT13 natural gas engine: Natural gas engines can play with high horsepower.
