Mpi systems utilize a single or dual fuel pumps to feed fuel injectors mounted in the intake port of the engine. These are categorized depending upon how the fuel is injected in the system. Some industrial diesel engines use multipoint fuel injection mpi similar to that used in most cars. We carry many efi systems many selftuning and selflearningfrom the top players in engine performance, including msd ignition, edelbrock, holley, fast, accel, chevrolet performance, quick fuel, and more. There are a few different types of fuel injection systems, and each one requires a certain type of maintenance and repair. Fuel injection atomizes the fuel through a small nozzle under high pressure. Materials for high pressure fuel injection systems department of. In this injection system, the fuel will be directly injected into the cylinder without the aid of the compressed air as like in the air injection system. Les moteurs et aeroplanes antoinette antoinette engines and aeroplanes pdf in. Pdf flow in fuel injection systems for di diesel engines. Hope you understand how the engine type affects the injection of a fuel. Fuel injection is the introduction of fuel in an internal combustion engine, most commonly.
Flow in fuel injection systems for di diesel engines. The fuel is injected directly into an open combustion chamber formed by the piston and cylinder head. The functional objectives for fuel injection systems can vary. These can be split into categories based on where the fuel is added. Carburettor relies on suction created by intake air accelerated through a venturi tube to draw the fuel into the mainstream. In a petrol engine, fuel injection is carried out by a carburettor. This can be also called as the airless mechanical injection system. The impeller type pump uses a vane or impeller that is driven by an electric motor. As the name suggests, this injection system has different ports for fuel injection. The main advantage of this type of injection is that it is. Introduction to fuel injection systems and components.

There is various fuel injection system used in automobile engineering. Over time, the point of injection has moved closer and closer to the cylinders themselves. The other types of fuel injection are that of multiport fuel injection. Line from hp pump to rail often uses ball type fittings onetimeuse. Solid injection systems can be classified into four types. The earliest and simplest type of fuel injection, singlepoint simply replaces the carburetor with one or two fuelinjector nozzles in the throttle body, which is the throat of the engines air intake manifold. This is all for the basic differences between the injection systems. The three major types of fuel injection are known as throttle body injection, multiport injection, and direct injection. For some automakers, singlepoint injection was a stepping stone to the more complex multipoint system. Solid injection system in this system the liquid fuel is injected directly into the combustion chamber without the aid of compressed air. Know the requirements for a basic fuel system for a diesel engine.
