What brand is the diesel engine of the BAIC BJ40?
1 Answers
The diesel version of the BAIC BJ40 uses a Yuchai engine. Yuchai heavy-duty engines are suitable for buses, trucks, construction machinery, etc. Therefore, this engine is a domestically produced engine. The engine model of the BAIC BJ40 diesel version is HY4C20B, with a maximum power of 170 kW, a maximum torque of 345 Nm, a maximum horsepower of 231 Ps, a maximum power speed of 5200 rpm, and a maximum torque speed of 1900-4000 rpm. For the daily maintenance of the BAIC BJ40 diesel engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to bypass through the bypass valve, bringing contaminants back to the lubrication area, accelerating engine wear and internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
