Inject the fuel with the correct spray pattern and sufficient atomization as demanded by the design of the combustion chamber. Inject the fuel at the correct rate (per unit time or crank angle degree). HISTORY OF FUEL INJECTION By FRANK DeLUCA, Chief Fuel Injection Engineer, of American Bosch Arma Corporation. Inject the fuel at the correct time (with respect to crank angle) in the cycle. Because of its greater immunity to wildly changing g- forces on the engine, the concept was adapted for use in gasoline- powered aircraft during World War II, and direct injection was employed in some notable designs like the .ĭistribute the metered fuel equally among cylinders in a multi- cylinder engine. Fuel injection was in widespread commercial use in diesel engines by the mid- 1. This system was adapted and improved by Robert Bosch and Clessie Cummins for use on diesel engines . History and Development: History and Development Herbert Akroyd Stuart developed the first system laid out on modern lines with a highly accurate 'jerk pump' to meter out fuel oil at high pressure to an injector. The basic function of a fuel injection system is to inject fuel to the engine cylinders in proper quantity, at correct time and at a pre- determined rate. Most fuel injection systems are for gasoline or diesel applications. Fuel Injection System.Ī fuel injection system is designed and calibrated specifically for the type(s) of fuel it will handle.

Vickers engines with the common rail fuel system were first used in 1916 in the G-class submarines. It has become the primary fuel delivery system used in automotive petrol engines, having almost completely replaced carburetors in the late 1.Ĭommon rail direct fuel injection is a direct fuel injection system for petrol and diesel engines.
