What is the fuel injection pressure of the Xingyue L?
2 Answers
The fuel injection pressure of the Xingyue L is around 300. The fuel injection pressure for gasoline engines is: For naturally aspirated engines, it is generally 2.5-3.5 bar, while for direct injection fuel lines, the pressure is typically 120-200 bar. Definition of the fuel injector: The fuel injector itself is a normally closed valve (a normally closed valve means that when there is no control signal input, the valve remains closed; whereas a normally open valve remains open when there is no control signal input), controlled by the up and down movement of a valve needle to open or close the valve. Reasons for low pressure: Dirty diesel fuel, impurities in the high-pressure fuel line causing the needle valve pair to not close tightly, high-pressure gas in the combustion chamber backflowing, burning out the needle valve pair, etc.
I've been driving the Xingyue L for almost two years now. The fuel injection pressure is around 200 bar, and the system is quite intelligently designed. The high pressure ensures finer fuel atomization and more complete combustion, resulting in quick acceleration and good fuel efficiency. I can achieve around 8 liters per 100 kilometers in the city. During maintenance, the technician mentioned that Geely adopted this direct injection technology to reduce emissions, but it's important to pay attention to fuel quality—avoid using low-grade gasoline, as it can easily cause carbon buildup and clog the injectors. I make it a habit to add a fuel system cleaner every 5,000 kilometers to keep the system running smoothly. Additionally, stable fuel injection pressure is crucial for engine longevity. If you notice a drop in power or unusual noises, it's best to check the fuel pump and sensors immediately. Overall, the driving experience is smooth and efficient, and with proper maintenance, the costs are reasonable. I'd recommend it to practical-minded car owners.
