The Besturn B50 is equipped with the CA4GB16 engine model, which delivers a maximum horsepower of 109 HP, a maximum power output of 80 KW, a power peak at 4500-5500 rpm, and a maximum torque of 155 Nm. The Besturn B50 engine is produced by the Dalian Engine Plant. Here are some daily maintenance methods for the Besturn B50 engine: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, its performance will degrade, leading to various engine issues. To prevent malfunctions, change the oil periodically 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 becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or bypass the safety valve, carrying contaminants back to the lubrication areas, accelerating engine wear and increasing 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 particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

I remember when I drove the Besturn B50, the engine was really crucial. It was manufactured by FAW in their Changchun plant, using a self-developed core, but some technologies referenced the Mazda platform. In daily driving, the power output was quite smooth, with no sluggishness during starts, and enough kick-down feeling when overtaking on highways. Fuel consumption was decently controlled, averaging around seven liters per hundred kilometers, making it economical for commuting. However, regular maintenance is essential—don’t skimp on engine oil, or carbon buildup could affect performance. Over time, you might notice slightly louder engine noise, but it’s not a major issue. Overall, domestic production costs make it highly cost-effective, and for repairs, visiting the 4S store is more reliable since the parts are exclusive and dependable. If I were to change cars, I’d prioritize models with similar domestic-engine specs.

From experience, the core components of the Besturn B50's engine are manufactured at FAW's Changchun production base. In my daily interactions, I've found this engine to be highly durable, with a design that combines domestic technology and some overseas optimizations. It runs stably with few major issues, but I recommend changing the oil and filter every 5,000 kilometers to keep the intake tract clean and avoid carbon buildup. If left idling for extended periods, the electronic control system may issue warnings, requiring prompt diagnosis. When purchasing, it's crucial to check if the engine number matches the factory origin to avoid reassembled units. Overall, it's reliable with low maintenance costs, making it a great choice for family users. Compared to joint-venture cars in the same price range, this engine's reliability is truly impressive.

The engine of the Besturn B50 is produced at FAW's Changchun plant in Jilin, China. After research, it's known to be modified based on the Mazda platform, emphasizing high compression ratio and ECU management, with optional displacements of 1.6L or 1.8L, delivering linear power output and fuel efficiency. It accelerates quickly when driven, with slightly noticeable noise that can be improved through sound insulation. Most user feedback is positive, highlighting its high cost-performance ratio.
