Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. . All diesel engines use fuel injection by design. Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke.Sep 27, 2018 Aeronautical turbine fuel system general requirements injection system description lication photo governor for dieselPump Line Nozzle Injection SystemElectronic Fuel InjectionRead More Hydro Mechanical Diesel Fuel Injection Systems hydro-mechanical diesel fuel injection systems

Abstract: A number of heavyduty diesel engine manufacturers have developed their own electronic fuel injection systems. Examples include the Hydraulic Electronic Unit Injector (HEUI) and the Mechanically actuated Electronically Controlled (MEUI) systems by Caterpillar, and a number of systems by Cummins such as the Accumulator Pump System (CAPS), Quantum CELECT, HPI, and XPI injection systems.

How a fuel injection system works. Others use indirect injection in which the diesel fuel is injected into the specially shaped precombustion chamber which has a narrow passage connecting it to the cylinder head. Only air is drawn into the cylinder.

In order for the fuel injection system to fulfill its purpose, fuel must be transferred to it from the fuel tank. This is the role of the lowpressure fuel system components. The low pressure side of the fuel system consists of a number of components including the fuel tank, one or more fuel supply pumps and one or more fuel filters.

However, the conventional or first generation injectors open with hydromechanical pressure. Inside the conventional injector, a spring holds the needle valve in closed position until the pressure in the highpressure lines reaches the specific value. Furthermore, fuel injection systems on the CRDi diesel engines use UnitInjector

One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use port injection or a carburetor. A port injection system injects fuel just prior to the intake stroke (outside the cylinder). A carburetor mixes air and fuel long before the air enters the cylinder.

Jan 27, 2012  Mechanical fuel injection is used to indicate the metering functions of the fuel injection system. Carburetor fuel injection is an advancement of the mechanical fuel injection method. The aim of all types of fuel injections systems is to achieve a delivery of the exact airfuel
