What is the Meaning of FSI?

[LaAlessandra]

FSI stands for Fuel Stratified Injection technology, which achieves a perfect combination of engine power and fuel economy under the same displacement. It is a relatively mature and advanced direct fuel injection technology in the automotive industry. This technology utilizes electronic chips in fuel-injected engines to precisely control the injection quantity into the cylinder for combustion through calculation and analysis, thereby improving the engine's fuel mixture ratio and subsequently enhancing engine efficiency. Compared to traditional engines, FSI-based engines exhibit better dynamic response, simultaneous improvement in power and torque, and lower fuel consumption. FSI engines have at least two combustion modes: stratified combustion and homogeneous combustion, with the latter further divided into homogeneous lean combustion mode and homogeneous combustion mode.
