The QSK50 builds upon its legendary robustness with an extended ratings range, improved power delivery, and upgrades to meet Euro Stage V emissions levels.

This is the latest evolution of the Cummins QSK50 engine which includes the Modular Common Rail Fuel System (MCRS) and Ferrous Cast Ductile (FCD) power cylinder. It has been designed using the experience of the K50 and its proven exceptional level of reliability.

Features & Benefits

Modular Common Rail Fuel System (MCRS) — This system maintains high injection pressures regardless of engine speed for exceptional performance at every rpm.
Quantum System — It continuously monitors engine conditions and automatically adjusts for peak operation.
Low-temperature aftercooling with single stage turbocharging — This feature reduces mechanical and thermal stress while lowering emissions, providing a compact engine envelope while maintaining engine accessibility.
FCD Power Cylinder — Proven ferrous cast ductile iron /steel pistons ensure maximum durability and reliability. Individual, seven-bolt, cross-flow cylinder heads provide high efficiency and excellent pressure capability.
Enhanced Camshaft and Gear Train — A large-diameter micro-finished camshaft and a heavy-duty gear train with high-contact ratio spur gears provide higher capacities and greater durability.
Prelub™ System — This system prevents starts without oil pressure, eliminating dry starts and improving engine life.
ELIMINATOR™ — Save up to 90% of lube system maintenance costs and increase productivity.
CENTINEL™ — The device constantly monitors engine duty cycle and load factors, removing small amounts of used oil as required and replenishing them with new oil.
875,000 gallons to overhaul — Proven power cylinder, one-piece cast-iron block, heavy-duty crankshaft and connecting rods allow a life-to-overhaul of up to 875,000 gallons (3,312,235 liters) of fuel burned with no mid-life overhaul required.
