MPFI (Multi Point Fuel Injection) This technology is principally developed for petrol engines to deliver more power with efficient use of fuel and resultant in less harmful emissions. The older engines worked with carburetor which sends a fix ratio of fuel and air to the cylinders for burning. It doesn’t judges of how much fuel is needed at what time. There are times when the engine is only idling at a traffic signal, or is just rolling downhill, so at that times injecting the fuel in the same amount is useless. The MPFI technology uses a microchip to control the quantity and timing of fuel injection to various cylinders. It opens and inserts the fuel to individual cylinders as per needed. The calculation is of chip is done on various factors like pressure on accelerator pedal, position of piston and current speed of piston movement. This overall process results in less harmful emissions and improved efficiency.
