M11 series engine product performance characteristics   

• Advanced technology, world quality

The leading technology of American Cummins is widely used in heavy trucks in North America and Europe.    

• Super power, green and environmentally friendly

Large displacement: While meeting the power requirements of heavy trucks, it also ensures that the engine has higher reliability, durability and safety.    

High power: most With a maximum power of 420 horsepower, it meets the fast, efficient and safe requirements of modern logistics.

High torque: the most The large torque is 1650N.m and the power is strong, meeting the requirements of starting heavy trucks and going up long slopes.

Light weight: It weighs only 940 kilograms and has a large power-to-weight ratio.

Excellent emission: The engine has good steady-state exhaust smoke at full load and meets Euro 3 standards.

• Low fuel consumption and good economy

Dalian diesel generator Cummins PT fuel system, ultra-high injection pressure, ensures good engine atomization and sufficient combustion.

The efficient Holset exhaust gas turbocharger can ensure more adequate air intake, improve engine efficiency, further improve combustion, and reduce engine specific fuel consumption.

Air-to-intercooling technology ensures more adequate air intake and better fuel economy.

The STC separate timing system ensures better combustion under high and low load conditions.

• Compact structure and easy maintenance

Replaceable wet cylinder liner has good heat dissipation effect and is easy to replace.

The parts of all models are highly versatile, highly serialized and easy to maintain.

Both the cylinder block and the cylinder head adopt built-in pressure lubricating oil passages, which have compact structure and low failure rate.

• Advanced design Reliable performance

Cylinder body: Made of high-strength alloy cast iron, with good rigidity, small vibration and low noise.

Cylinder head: Four-valve design per cylinder, optimized air / fuel mixing ratio, effectively improving combustion and emissions; integrated cylinder head for easy maintenance.

Camshaft: The single camshaft design can accurately control valve and injection timing, and the optimized cam profile can reduce impact force and improve reliability and durability.

Crankshaft: An integral crankshaft made of high-strength forged steel. The induction quenching process of fillets and journals can ensure higher fatigue strength of the crankshaft.

Piston: Using the latest aluminum alloy casting technology, the ω -shaped head and articulated design can compensate for thermal expansion and contraction to ensure good fit.

• Professional configuration Excellent quality

Lubrication system: All moving parts are forced lubrication; the large-capacity gear pump provides pressure lubricating oil to lubricate the bearings and cool the pistons; the oil cooler and composite filter maintain good oil condition.

Fuel system: Cummins PT fuel system optimizes combustion and provides surging power; STC distributed timing system ensures better combustion in all working conditions; a low-pressure fuel supply system is configured with a one-way fuel circuit, which is safe and reliable.

Cooling system: forced water cooling by gear centrifugal water pump, large flow water channel design, good cooling effect; spin-on water filter and special DCA additive can effectively prevent rust and cavitation, control coolant acidity and remove impurities.

Intake and exhaust system: The efficient Holset exhaust gas supercharger further improves combustion; the pressure-type pulse exhaust pipe can make full use of exhaust gas energy and improve engine efficiency; air-to-air intercooling technology ensures better fuel economy and emissions.

• Mature products, famous all over the world

Wide application: Since the joint venture in 1995 , the M11 series engines have been widely used in tractors, cement mixer trucks, mining vehicles, engineering machinery, power generation, ship power and other fields; it has formed strategic partners with important customers.

High reputation: As one of the main models of the Cummins family, the M11 engine has won high recognition from customers in various fields for its strong power, ultra-low fuel consumption, high reliability and low maintenance costs.

Technology upgrade: Air-to-intercooling technology improves engine reliability, power, fuel economy, emissions and other indicators. The electronic fuel system further enhances the M11 engine's leading position in China's high-horsepower engine manufacturing industry.
