Hot sale mining machine original spare parts 22456989 202 kw 270 hp 2100 rpm QSL QSL9 complete diesel engine assy

Engine Type: The QSL9 is a 4-stroke, turbocharged, and air-to-air aftercooled diesel engine. It operates on the compression-ignition principle, where fuel is injected into the combustion chamber and ignited by the heat of compression.

Displacement: The engine has a displacement of 8.9 liters (or 540 cubic inches), which refers to the total volume of air and fuel that the engine's cylinders can displace during one complete cycle.

Power Output: The QSL9 diesel engine is known for its high power output. It typically delivers a range of power options, varying based on specific applications and customer requirements. The power output can range from around 250 horsepower (186 kW) to 400 horsepower (298 kW) or more.

Emissions Compliance: The QSL9 engine assembly meets stringent emissions regulations, such as those set by the Environmental Protection Agency (EPA) in the United States and similar organizations worldwide. The engine employs advanced technologies, such as selective catalytic reduction (SCR) and exhaust gas recirculation (EGR), to minimize harmful exhaust emissions.

Cooling System: The engine features an efficient cooling system that includes a radiator and an air-to-air aftercooler. The aftercooler helps reduce the temperature of the compressed air before it enters the combustion chamber, optimizing combustion and improving engine performance.

Fuel System: The QSL9 utilizes a high-pressure common rail fuel injection system. This system delivers precise amounts of fuel at high pressure to each cylinder, ensuring efficient combustion and optimized fuel consumption.

Lubrication System: The engine assembly is equipped with a full-flow oil filter and a bypass filter to remove contaminants and ensure clean oil circulation throughout the engine. An integrated oil cooler helps maintain proper oil temperature during operation.

Electrical System: The QSL9 diesel engine has a 24-volt electrical system, which powers various components, including the starter motor, alternator, and engine control module (ECM).

Weight and Dimensions: The weight and dimensions of the QSL9 engine assembly can vary depending on specific configurations and additional equipment. However, as a general guideline, the engine typically weighs between 1,600 to 2,000 kilograms (3,527 to 4,409 pounds) and has approximate dimensions of 1.6 meters (5.2 feet) in length, 1.0 meter (3.3 feet) in width, and 1.2 meters (3.9 feet) in height.

Application: The QSL9 engine assembly is designed for a wide range of applications, including heavy-duty trucks, construction machinery, agricultural equipment, industrial generators, and marine propulsion systems. It offers versatility and reliability to meet the demands of various industries and operating conditions.
