No overhaul occurs within one million kilometers mileage after being verified though 450 billion km mileage.

Reliable Design and Assured Quality

With a simple and effective structure, the modular design of Cummins ISM 11 Engine effectively reduces weight and improves operational efficiency. Both the surface and the interior of cylinder are reinforced by reinforcing bars, ensuring better strength and rigidity than the competing products while maintaining the light weight.

Mid-stop cylinder liner avoids deformation and prevents from abnormal wear between the piston and the liner. Articulated piston withstands higher mechanical and thermal load, eliminating knocking at low temperature and scuffing at high temperature, Cummins Celect fuel system (low-pressure fuel line) has been designed to eliminate risks of fuel leakage.

Large amount of oil into and from the fuel injector prevents injector from stuck, And, the flowing fuel also cools down the ECM -the brain of the Engine,extending the service life of ECM.

By unique combination of viscosity sensor, pressure regulator and relief valve, the lubrication system automatically regulates the engine oil pressure, ensuring lubrication effects in all seasons.

The package design of engine oil thermostat, radiator and bypass valve guarantees an optimal working condition for the Engine and effectively prolongs the oil change interval. 4-step pressure regulator for turbocharging system can improve response speed to prevent overheart, overspeed and abnormal wear

Great Power, Pioneer of Energy Saving

Cummins’ proprietary Celect fuel system, which injection pressure exceeds 1800bar, utilizes single-cylinder, four-valve technology. Good fuel atomization and full combustion ensure high fuel economy while maintaining great power.

The speed of silicon oil fan can be controlled electronically based on engine temperature, saving fuel and reducing noise.

Quality Manufacturing Being Trusted Widely

As a global model factory of Cummins, XCEC builds up excellent capability by using state-of-art manufacturing equipment, standard processes, sophisticated testing devices and strict quality control procedures.

Moreover, XCEC shares excellent quality parts globally to maintain consistent quality.

It strives to maintain the pure bloodline of the products through strict processes and therefore won trusts of millions of users with reliable quality.

The Engine is regarded as the most trusted heavy duty engine by truck drivers. The red “heart” embodies hundred-year history of Cummins’ quality, and also will witness a promising future of manufacturing in China More reliable, more economical and more powerful.

This is the excellent quality of Cummins ISM 11 flagship power from the U.S., as you expect.

Strong Power Leading the Industry

As Cummins flagship non-road engine product, QSM11-C full electronic-controlled engine has a great reputation in global engineering machinery industry. The engine has been localized in Xi’an Cummins Engine Company Limited. It features excellent reliability, durability, fuel economy and safety, and has been widely used in many engineering machinery fields such as rotary drilling rigs, truck cranes/crawler rigs, mining trucks, oil field equipment, reach stackers, wheel loaders and rail cars.

Compared with ISM11 model, QSM11-C non-road engine has more stringent requirements for durability and strength, so the parts have higher strength, surface hardness and wear resistance. Compared with Max./Min.

Speed governing system of ISM11, QSM11-C can be used to realize all-speed governing with faster transient response, and can better satisfy the needs under complex operating conditions for engineering machinery.

Mature Technology Providing Excellent Quality

Cummins patented combustion chamber ensures more sufficient combustion to provide strong and continuous power.

Cummins patented fuel injection control system, with a fuel injection pressure up to 1800 bar (200 bar more than other engines), has good atomization and more sufficient combustion.

Optimized turbocharging system with a bypass valve is provided with machined impellers and has higher reliability.

The world’s leading electronic control system can be used to optimize transient response and power output, fully monitor the operation status of the engine, automatically diagnose faults and quickly give alarms.

Meet international leading non-road emission regulations and standards.

Reliable Quality and High Dispatching Ratio

Key assemblies and parts are imported from the US, including cylinder block, cylinder head, piston, camshaft and connecting rod mechanism, which are reliable and durable.

The production standard, manufacturing procedures, assembling process and quality control system are based on Cummins’s global uniform standard.

Integrated error correction system and assembly control system ensure zero defect on production lines.

Imported test bench (AVL) based Cummins standard must be used to inspect all off-line engines completely to ensure best performance of QSM11-C.

Easy to Deal with Complex Operating Conditions

Strong oil adaptability

· Cummins patented Celect fuel system adapts to impurities less than 10 microns, and can be better operated under the operating environment for engineering machinery products.
