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 QSL9 engine has a displacement of 8.9 liters, which is equivalent to 540 cubic inches. Displacement 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 offers a wide range of power options to meet various applications and customer requirements. The power output typically ranges from around 250 horsepower (186 kW) to 400 horsepower (298 kW) or more, depending on the specific configuration.
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. It incorporates advanced technologies like selective catalytic reduction (SCR) and exhaust gas recirculation (EGR) to minimize harmful exhaust emissions and ensure compliance with emission standards.
Cooling System: The engine features an efficient cooling system to maintain optimal operating temperatures. It 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 advanced fuel system delivers precise amounts of fuel at high pressure to each cylinder, ensuring efficient combustion, improved fuel economy, and reduced emissions.
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, enhancing lubrication efficiency and prolonging the engine's lifespan.
Electrical System: The QSL9 diesel engine has a 24-volt electrical system. This system powers various components, including the starter motor, alternator, engine control module (ECM), and other auxiliary electrical devices.
Weight and Dimensions: The weight and dimensions of the QSL9 engine assembly can vary depending on specific configurations and additional equipment. As a general guideline, the engine typically weighs between 1,600 to 2,000 kilograms (3,527 to 4,409 pounds). The dimensions can vary, but it usually has a length of approximately 1.6 meters (5.2 feet), width of 1.0 meter (3.3 feet), and height of 1.2 meters (3.9 feet).
Applications: The QSL9 diesel engine assembly is designed for a wide range of applications across various industries. It is commonly used in heavy-duty trucks, construction machinery, agricultural equipment, industrial generators, and marine propulsion systems. Its versatility and reliability make it suitable for demanding environments and operating conditions
