Up until the mids, the majority of cars had carburetors; however, today, every car on the market, regardless of price, has a Multi-Point Fuel Injection System MPFI.

By all odds, the engine is the most important part of any car, and its life very much depends upon the way fuel is supplied to it. While carburettors used to do this duty until the mids, it was in the late 90s when multi point fuel injection systems made their way to the Indian market, and then rapidly popularised themselves for their best efficiency. The multi point fuel injection system is one of the best engineering marvels ever produced, and today, every petrol and CNG car, irrespective of its price, comes with MPFI. In this article, we learn what MPFIs are and how they function. The carburettors mix the air-fuel in the required ratio, and supply it to the intake manifold. Due to the absence of electronic control, a carburettor cannot properly measure the air-fuel ratio with changing air pressure and fuel temperature. These fuel injectors inject an optimum quantity of fuel into the combustion chamber, which also results in better atomization and swirl of fuel in the combustion chamber.

Up until the mids, the majority of cars had carburetors; however, today, every car on the market, regardless of price, has a Multi-Point Fuel Injection System MPFI. The first mass-market MPFI automobiles were introduced here in the late s, and as time went on, as emission standards tightened and automakers focused more on boosting vehicle efficiency, every car on the market began to include this technology. After the various articles published on this site on a fuel injection system in internal combustion engines, here we are on the multi-point injection types. The multi-point injection is a system or technique in which fuel is introduced into the cylinder of an internal combustion engine. Just as earlier mentioned, the MPFI is a system of injecting fuel into an internal combustion engine through multiple ports situated on the intake valve of each cylinder. Conventionally, petrol or gasoline engines are also called spark ignition SI engines. The purpose of these fuel injectors is to inject a precise quantity of fuel into the chamber. In a batched MPFI system, fuel is injected into a group or batches of cylinders without bringing their intake stroke together.
