Product Description
The QSK19-C860 is a remarkable engine model developed , renowned for its high performance and reliability in various applications.
Engine Configuration
This engine features an in-line 6-cylinder design, which provides a smooth and balanced operation. The 6-cylinder configuration offers good power output and torque characteristics, making it suitable for demanding tasks. With a displacement of approximately 19 liters, it has the capacity to generate substantial power, typically ranging from 506 to 800 horsepower (377 - 597 kW) in its diesel variant, allowing it to handle heavy workloads with ease.
Advanced Fuel System
The QSK19-C860 is equipped with a sophisticated fuel system. It utilizes high-pressure injection technology, such as the modular common rail fuel system (MCRS), which enables precise control of fuel delivery. This results in more efficient combustion, improving fuel economy and reducing emissions. The electronic fuel pumps can deliver injection pressures of up to 1600 bar, eliminating the need for mechanical linkage adjustments and enhancing the overall performance and reliability of the engine.
Turbocharging and Air Intake
A single-stage Holset turbocharger is incorporated into the QSK19-C860 design. This turbocharger helps to increase the air density entering the engine by lowering the intake air temperature. The increased air density allows for more complete combustion, resulting in greater power output while also reducing emissions. Additionally, the engine requires the use of an air-to-air heat exchanger or charge-air-cooler (CAC) to further optimize the intake air temperature and meet strict emissions requirements.
Electronic Controls
Full-authority electronics are a key feature of the QSK19-C860. It is equipped with an upgraded CM850 ECM (Engine Control Module) that has twice the processing speed of its predecessor. The programmable electronic controls optimize combustion under all altitudes and operating conditions. This advanced electronic control system not only improves performance but also enables better diagnostics, making it easier to identify and address any potential issues promptly.
Durability and Reliability
The engine's design emphasizes durability. It incorporates precision-honed cylinder liners, which, along with superior metal technology, create an exceptionally smooth and durable surface. The power cylinder package consists of proven single-piece ferrous cast ductile iron pistons that can withstand high injection pressures and offer maximum durability and reliability. The high-durability camshaft, with micro-finishing, has a lifespan twice as long as previous designs, and the improved contact between the crosshead and rocker lever further reduces wear.
Filtration System
The QSK19-C860 features a two-stage oil filter system, combining a full-flow and bypass oil filter. This design helps to extend service intervals and reduce maintenance costs while ensuring clean oil is supplied to the engine components, enhancing their longevity. The Fleetguard® ES filtration system used in the engine keeps the equipment running smoothly by providing effective filtration and simplifying maintenance procedures.
Applications
Thanks to its impressive performance and reliability, the QSK19-C860 finds wide applications in various industries. It is commonly used in mining operations, where it powers large mining trucks and other heavy machinery. In the power generation sector, it serves as a reliable source of standby or prime power for industrial and commercial applications, providing stable and efficient electricity supply. Additionally, it is also suitable for other heavy-duty applications such as oil and gas exploration, construction, and marine propulsion, where high power and durability are essential requirements.
