Cummins Diesel advantage of the characteristics of advanced design and reliable performance of the cylinder: high-strength alloy cast iron, rigidity, vibration, low noise. Head: four-valve per cylinder design, optimized air / fuel ratio, improve combustion and emissions; one per cylinder cover for easy maintenance. Camshaft: DOHC design can accurately control valve and injection timing, cam profile optimization can reduce the impact force, improve reliability and durability. Crankshaft: high strength forged steel crankshaft overall, induction hardening process and journal fillets can guarantee higher fatigue strength of the crankshaft. Pistons: aluminum alloy using the latest technology, ω-type head and barrel skirt designed to compensate for thermal expansion and contraction, to ensure a good fit. Professional configuration best quality lubrication system: All the moving parts are forced lubrication; high-capacity gear pump provides pressure lubricating bearings are lubricated and cooled piston; oil cooler, full-flow filter, bypass filter to maintain good oil state. Fuel system: Cummins PT fuel system patented technology to optimize combustion, power surge; STC distributed timing system to better ensure all conditions of combustion; low-pressure fuel system, fuel-way loop configuration, safe and reliable. Cooling system: forced water cooling gear from the pump, a big flow waterway design, cooling effect; spin-mounted water filters and special additives DCA can effectively prevent corrosion and cavitation, control coolant acidity and remove impurities. Intake and exhaust systems: efficient Holset turbocharger to further improve the combustion exhaust gas; pressure pulse exhaust pipe can take full advantage of exhaust energy, improve engine efficiency; Air Cooling technology ensures better fuel economy and emissions.
