MPI stands for Multi-Point Injection on a Mercruiser engine.
This technology refers to a fuel injection system where fuel is delivered to each cylinder individually through multiple injectors, rather than using a single injector for the entire engine (as in throttle-body injection systems). Each injector is placed near the intake valve, allowing for precise fuel delivery to each cylinder, which leads to more efficient combustion and better overall engine performance.
Here’s what MPI technology offers:
-
Improved Fuel Efficiency: By delivering the exact amount of fuel needed to each cylinder, MPI systems reduce fuel wastage and improve the engine’s fuel economy.
-
Enhanced Performance: MPI systems allow for better air-fuel mixture control, resulting in smoother acceleration, more power, and better throttle response.
-
Lower Emissions: With more precise fuel delivery, MPI systems help engines run cleaner, reducing harmful emissions compared to older carbureted systems or single-point injection systems.
-
Better Reliability: MPI engines are generally more reliable due to the more controlled and efficient fuel delivery, reducing the chances of engine knocking or misfires.
Overall, MPI is a key technology that enhances the performance, efficiency, and reliability of Mercruiser engines, making them well-suited for a variety of marine applications.
