What brand is the BJ40 diesel engine?

The brand of the BJ40 diesel engine is Yuchai. It is an engine originally from Swedish Saab, which was acquired by BAIC and is now produced by BAIC itself. The BJ40 diesel engine model is 4F20TC13, with a maximum horsepower of 163, a maximum power output of 120kw, a maximum power speed of 4000rpm, and a peak torque of 680N.m. For daily maintenance of the BJ40 diesel engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB_CD grade diesel engine oil according to the mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, change the oil regularly according to 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 becomes 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 and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. 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 particles from component wear to form sludge. In small amounts, this sludge remains suspended in the oil, but in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
I've always been quite interested in the Beijing BJ40. Its diesel engine models typically come from Beijing Foton Cummins, especially the ISF2.8 series. As a representative of Chinese-made off-road vehicles, Foton Cummins is a globally renowned brand specializing in diesel engines, known for their stable power output and exceptional torque during off-road climbing—unlike gasoline engines that tend to overheat easily. I once drove a friend's BJ40 on a countryside trip and found the engine incredibly durable with decent fuel efficiency, averaging around 8 liters per 100km on highways, making it suitable for long-distance travel. If you're considering buying this type of vehicle, opting for the diesel version is mainly due to the engine's reliability, lower maintenance costs, and smoother performance in city traffic without the jerky feel common in gasoline engines. Of course, the engine noise is a bit loud, but that's part of the rugged off-road character. Overall, it's a cost-effective and capable machine.
