What is the difference between direct injection and multi-point electronic injection?
1 Answers
The difference between direct injection and multi-point electronic injection lies in the fuel injection method: direct injection sprays fuel directly into the cylinder; multi-point electronic injection has injectors mounted on the intake manifold, where fuel and air begin to mix in the manifold before entering the cylinder. The engine generates power by burning fuel and air, and the fuel enters the cylinder through "injection." For electronic fuel injection engines, the key component is the fuel injector. If it becomes clogged, it can cause unstable idling, increased fuel consumption, poor acceleration, difficulty starting, excessive emissions, and in severe cases, completely block the injector, damaging the engine. If the injectors are installed on the intake pipe of each cylinder, meaning gasoline is injected from multiple locations (at least one injection point per cylinder), this is called multi-point electronic injection.
