What Does Dual Injection Mean?
3 Answers
Dual injection is a fuel injection technology that combines the advantages of multi-point fuel injection and direct injection, leveraging the strengths of both while mitigating their respective weaknesses. Here is expanded information about dual injection: 1. Typically, the multi-point fuel injection system is only used when the vehicle is driving at low speeds, which can prevent carbon buildup while avoiding issues caused by insufficient power. 2. However, during high-speed driving, direct injection is employed, which not only enhances engine power but also prevents excessive carbon buildup. 3. The seamless switching and timely regulation between these two systems constitute dual injection.
Hybrid injection refers to an engine fuel system technology that flexibly switches between direct injection and port injection under different conditions. Simply put, when the engine operates under low load, such as during city commuting, the system prioritizes port injection, spraying fuel in front of the intake valve, which helps prevent carbon buildup. When more power is needed, such as during highway overtaking, it switches to direct injection technology, injecting fuel directly into the cylinder to improve combustion efficiency and output. This design balances performance and fuel economy, making the car run smoother, more fuel-efficient, and reducing emissions. Many new car models are now equipped with this technology, especially in some Japanese brands, significantly enhancing daily driving experience.
Hybrid injection refers to the engine's fuel injection system utilizing two methods to handle the fuel delivery: one injects fuel at the intake port, while the other directly injects it into the cylinder. The system automatically switches between these methods based on vehicle speed and engine load. For example, during slow-speed driving, it tends to use port injection to prevent carbon buildup; when accelerating or climbing hills, it switches to direct injection to enhance power output. The benefits include improved reliability, reduced likelihood of issues, and enhanced fuel efficiency, saving you money on gas. I believe this technology is relatively simple to maintain, requiring only checks on the fuel injectors and sensors during servicing, making it suitable for most car owners' daily use.
