A. Cummins generator set has low oil consumption and good economy.
Cummins patented PT fuel system with ultra-high injection pressure ensures good atomization and full combustion of the engine.
An efficient exhaust gas turbocharger can ensure more sufficient air intake, improve engine efficiency, further improve combustion and reduce the fuel consumption rate of the engine.
Air-to-air cooling technology ensures more adequate air intake and better fuel economy.
B. compact structure and convenient maintenance.
Replaceable wet cylinder liner, good heat dissipation effect and convenient replacement.
All machine parts have strong universality, high serialization and convenient maintenance.
Both the cylinder block and the cylinder head adopt built-in pressure lubricating oil passages, which have compact structure, low failure rate, advanced design and reliable performance.
Cylinder block: made of high strength alloy cast iron, with good rigidity, small vibration and low noise.
Cylinder head: four valves per cylinder design, optimize air-fuel ratio, effectively improve combustion and emissions; Each cylinder has a cover for easy maintenance.
Camshaft: Single camshaft design can accurately control valve and injection timing, and optimized cam profile can reduce impact force and improve reliability and durability.
C. Cummins professional configuration international quality
Lubrication system: all moving parts are forced to be lubricated; Large-capacity gear pump provides pressure lubricating oil, lubricates bearings and cools pistons; The oil cooler, full-flow filter and bypass filter are kept in good oil condition.
Fuel system: PT fuel system with Cummins patented technology optimizes combustion and surges power; STC distributed timing system ensures better combustion under all working conditions; Adopt low-pressure oil supply system, equipped with one-way oil circuit, safe and reliable.
Cooling system: gear centrifugal pump is used for forced water cooling, with large flow waterway design and good cooling effect; Rotating water filter and special additives can effectively prevent corrosion and cavitation, control the acidity of cooling liquid and remove impurities.
Intake and exhaust system: efficient exhaust gas supercharger further improves combustion; Pressure pulse exhaust pipe can make full use of exhaust energy and improve engine efficiency; Air-to-air cooling technology ensures better fuel economy and emissions.
Crankshaft: An integral crankshaft made of high-strength forged steel. The fillet and journal induction quenching process can ensure that the crankshaft has high fatigue strength.
Piston: adopting the latest aluminum alloy casting technology, ω-shaped head and skirt design can compensate thermal expansion and cold contraction to ensure good fit.
