CHONGQING CUMMINS Engine【QSK38】

• Low fuel consumption and good economy
Minns patented technology of 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.
• 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, full-flow filter, bypass filter to ensure that the oil is in good condition.
Fuel system: Cummins patented PT fuel system, optimized combustion, power surging, STC step-by-time 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 control coolant acidity, prevent rust and cavitation 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.
