What is the difference between direct injection and multi-point injection?

[ONoah]

Here are the differences between direct injection and multi-point injection: 1. Different advantages: Direct injection gasoline engines have low fuel consumption and high power; multi-point injection replaces the design of multiple cylinders sharing one fuel injector. 2. Different disadvantages: Direct injection requires frequent replacement of parts such as spark plugs; multi-point injection engines have low injection pressure. 3. Different principles: Direct injection is a technology that directly injects fuel into the cylinder to mix with the intake air. Multi-point injection is completed by electronic injectors. The electronic injection device consists of three major parts: the fuel injection circuit, a set of sensors, and an electronic control unit. If the injector is installed in the original carburetor position, meaning the entire engine has only one fuel injection point, this is single-point injection.
