K19 series Cummins engine

Designed with advanced performance reliable
cylinder block: made of high-strength alloy cast iron, good rigidity, low vibration and low noise.
Cylinder head: Four valves per cylinder are designed, optimized air/fuel mixing ratio, combustion and emissions; one cover per cylinder, easy maintenance.
Camshaft: The single camshaft is designed to accurately control valves and fuel injection timing, and the optimized camline reduces impact, improves reliability and durability.
Crankshaft: The integrated crankshaft made of high-strength forged steel, the induction hardening process of rounded corners and journals can ensure higher fatigue strength of the crankshaft.
Piston: Use aluminum alloy casting technology, the ω-shaped head and barrel skirt design can compensate for thermal expansion and contraction, ensuring good cooperation.


Lubrication system: All moving parts are forced lubricated; large-capacity gear pump provides pressure lubricating oil to lubricate the bearing and cool the piston; engine oil cooler, full flow filter, and bypass filter maintain good engine oil condition.
Fuel system: PT fuel system with Cummins patented technology, optimized combustion and strong power; STC distributed timing system ensures good combustion in all working conditions; low-pressure oil supply system is adopted, equipped with a one-way fuel circuit, which is reliable.
Cooling system: Forced water cooling with gear centrifugal water pump, large flow water channel design, good cooling effect; rotary water filter and DCA additives can effectively prevent rust and cavitation, control the acidity of the coolant and remove impurities.

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