What are the differences between multi-point fuel injection and direct injection?
1 Answers
The following are the differences between multi-point fuel injection and direct injection: 1. Different definitions: Multi-point fuel injection refers to the process where gasoline fuel is injected into the intake manifold during the operation of a gasoline engine, controlled by a specific sequence of commands from the control program and executed by electronic fuel injectors. Direct injection, on the other hand, involves injecting fuel directly into the cylinder to mix with the intake air. 2. Different development speeds: The application of direct injection technology represents a significant attempt by people, and it is gradually replacing multi-point fuel injection. Moreover, the development of direct injection technology is progressing rapidly, with major automakers competing to research this technology, achieving quite remarkable results. Currently, Volkswagen is one of the automakers that has achieved relatively mature direct injection technology. 3. Different levels of fuel efficiency: Direct injection allows for a more balanced fuel injection compared to multi-point fuel injection vehicles, enabling more complete combustion of fuel during engine operation. This is an area where multi-point fuel injection vehicles can never match.
