Brief introduction of cummins QSK38-C1086 diesel Engine

The QSK38-C1086 is a V12 cylinder type engine with a 38 litre displacement.Which Developed from the robust K1500E, the QSK38 is designed to survive the toughest mining applications such as the 176 short ton (160 tonne) class excavators and large wheel loaders. The QSK38 features the Cummins Modular Common Rail (MCR) fuel system that maintains constant fuel injection pressure at all engine speeds – realizing greater application flexibility and precision by controlling both injection rates and timing. Multiple injection events during each power stroke yield smoother, more consistent power at every rpm, with an 18% faster load acceptance and 50% improved cold start than the K1500E. Single-stage turbocharging delivers reliable performance up to altitudes of 10,500 feet (3,200 m) without power derate. The QSK38 with the MCR system has significantly reduced noise emissions (80% lower at idle) and engine vibration than its predecessor, resulting in a safer and more comfortable work environment. Durability is excellent, with a conservative rating of 625,000 gallons-to-overhaul (2,365,882 liters). Cummins analysis-led computer modeling has designed piston combustion bowl geometry which allows the QSK38 to reduce NOx by 40% and particulate matter by 60%, achieving U.S. EPA Tier 2 emissions levels in-cylinder with minimal impact to fuel consumption.

QSK38 Specifications

QSK38-C1086 diesel Engine features And Benefits.

■ Advanced Modular Common Rail (MCR) fuel injection system generates clean, quiet and efficient power.

■ State-of-the-art combustion control system features enhanced electronics integrated with upgraded sensors and powerful new Electronic Control Modules (ECM) for peak performance at high altitudes and under every load condition.

■ Single-stage turbocharging for easy servicing and weight savings. Designed and built by Cummins Turbo Technologies, they feature a titanium impeller and watercooled bearing housings for long-term reliability, and a larger compressor to provide higher airflows for maximum power and long life.

■ Ferrous Cast Ductile (FCD) iron pistons provide increased strength and durability to handle increased cylinder pressures for longer life-to-overhaul.

■ Piston-cooling nozzles direct a cooling stream of oil beneath each piston crown and bowl rim for long life with increased reliability.
