Understanding Fuel Injection System in Petrol Engine (Working Principle + Diagram)

Fuel injection system is a system for supplying fuel into the engine through the spraying path. Most of fuel injection systems are applied to diesel engines. You may already be very familiar with the injectors found in all diesel engines. But the petrol engine also has a fuel injection system. Is the fuel injection system in the petrol engine the same as a diesel engine? let's discuss in detail. Dеfіnіtіоn оf Fuеl Injесtіоn Sуѕtеmѕ іn Pеtrоl Engіnеѕ Petrol engine uses gasoline as fuel, gasoline will be inserted into the cylinder along with fresh air at the suction step. In older vehicles, there is one component called a саrburеtоr , its function as a mixer of air and gasoline. The carburetor will supply gasoline into the intake manifold based on the pressure difference. The pressure inside the intake is lower because there is air flow acceleration which makes the gasoline sucked into the intake manifold. The result is fresh air and gasoline can be mixed. While the fuel injection sys…
