Q&A

Super power, green environmental protection
Large displacement: to meet the power requirements of heavy truck at the same time, to ensure that the engine has higher reliability, durability, safety.
High power: Maximum power up to 420 horsepower, to meet the requirements of modern logistics fast, efficient and safe.
Large torque: Maximum torque 1650N.m, strong power, to meet the heavy truck overload start and up long slope requirements.
Lightweight: Only 940 kg of self-weight, high power weight ratio.
Emission excellent: The engine full load steady-state exhaust smoke is good, to meet the Euro 3 standard.
• Reliable design with advanced performance
Cylinder BLOCK: The use of high-strength alloy cast iron manufacturing, good rigidity, small vibration, low noise.
CYLINDER head: four valve per cylinder design, optimize air/fuel mixing ratio, effectively improve combustion and emissions; overall cylinder head, easy maintenance.
Camshaft: Single camshaft design can precisely control the valve and injection timing, optimized cam line can reduce the impact, improve reliability and durability.
Crankshaft: The integral crankshaft, fillet and shaft neck induction quenching process made of high strength forging steel can ensure the fatigue strength of crankshaft is higher. PISTON: The use of the latest aluminum alloy casting technology, Omega Head and articulated design can compensate thermal expansion and contraction, to ensure good coordination.

• Advanced technology, World quality
Cummins leading technology in the United States, widely used in North America and Europe heavy truck.
• Low fuel consumption and good economy
Cummins patented PT fuel system, ultra-high injection pressure, to ensure that the engine atomization good, full combustion.
The efficient Holset exhaust gas turbocharger ensures fuller intake, improves engine efficiency, further improves combustion and reduces engine fuel consumption.
Empty medium cooling technology ensures fuller intake and better fuel economy.
STC timing system ensures that the combustion of high and low load conditions is better.
• Compact structure and easy maintenance
Replaceable wet cylinder liner, good heat dissipation effect, easy to replace.
All models of components have strong versatility, high serialization degree, easy maintenance.
Both the cylinder block and the cylinder head take the built-in pressure lubricant channel, the structure is compact, the failure rate is low.
• Professional configuration of the best quality
Lubrication system: All moving parts are forced lubrication; high-capacity gear pump provides pressure lubricant to lubricate the bearing and cool the piston; oil cooler, composite filter to maintain good oil status.
Fuel system: Cummins patented PT fuel system, optimized combustion, power surging, STC distribution timing system to ensure that the full operating conditions of better combustion, the use of low-pressure oil supply system, configuration of fuel unidirectional circuit, safe and reliable.
Cooling system: The use of gear centrifugal pump forced water cooling, large flow waterway design, good cooling effect, rotary water filter and special DCA additives can effectively prevent rust and cavitation, control coolant acidity and remove impurities.
Inlet and exhaust system: efficient Holset exhaust gas supercharger further improve combustion; pressure pulse exhaust pipe can make full use of exhaust gas energy, improve engine efficiency; Air air cooling technology to ensure fuel economy and emissions better.
• Mature products, renowned all over the
Wide range of applications: since the 1995 joint venture M11 series of engines are widely used in tractors, cement mixers, mining vehicles, construction machinery, power generation, ship power and other fields, and key customers to form strategic partners.
High reputation: As one of the main models of Cummins family, M11 engine has won high recognition from customers in various fields with strong power, ultra-low fuel consumption, high reliability and low maintenance cost. Technology upgrade: Air air cooling technology improves engine reliability, power, fuel economy and emission indicators.
The electronic fuel system further enhances the leading position of the M11 engine in China's high-powered engine manufacturing industry.
