Is There a Difference Between Direct Injection and Multi-Point Electronic Injection?

[OLandon]

Multi-point electronic injection refers to the electronic injection system of an automobile engine, which generally consists of three major components: the fuel injection circuit, sensor group, and electronic control unit. Direct injection technology is a new type of fuel injection technology. The difference between multi-point electronic injection and direct injection lies in the fact that the injectors in multi-point electronic injection do not extend into the cylinder, whereas the injectors in direct injection do. Multi-point electronic injection technology is more mature, has higher combustion efficiency, is cheaper, and is also more convenient to maintain. On the other hand, direct injection technology is more advanced, offering better performance in terms of energy saving and emission reduction compared to multi-point electronic injection, but it tends to produce more carbon deposits in the engine.
