Single-point fuel injection system in diesel engine pdf download was used extensively on American-made passenger cars and light trucks duringand in some European cars in the early and mids. This mechanical system was used by some MaseratiAston Martinand Triumph models between and The justification for single-point injection was low cost.
Diesel fuel injection systems downloae be classified into three categories, as follows: W8 W12 W16 W L-Jetronic first appeared on the Porscheand uses a mechanical airflow meter Fuel injection system in diesel engine pdf download for LuftGerman for “air” that produces a signal pdff is proportional to “air volume”. Air filter Blowoff valve Boost controller Butterfly valve Centrifugal-type supercharger Cold air intake Dump valve Electronic throttle control Forced induction Inlet manifold Intake Intercooler Manifold vacuum Naturally aspirated engine Ram-air intake Scroll-type supercharger Short ram air intake Supercharger Throttle Throttle body Turbocharger Twin-turbo Variable-geometry turbocharger Variable-length intake manifold Warm air intake.
Petrol engines can use gasoline direct injectionwhere the fuel is directly delivered into the combustion chamberor indirect injection where the fuel is mixed with air before the intake stroke. Scania fordonshistoria in Swedish.

This page eiesel last edited on 10 Novemberat The fuel system on a diesel engine is a highly specialized set of components which must deliver the correct amount of fuel to the cylinder at the precise moment it is needed.
Throughout the early history of diesels, they were always fed by a mechanical pump with a small separate fuel injection system in diesel engine pdf download for each cylinder, feeding separate fuel lines and individual injectors. Following this racetrack success, the Mercedes-Benz SLthe first production sports car to use fuel injection, used direct injection.
Mechanics of a Diesel Fuel Injection System. Most modern diesel engines use common rail or unit injector direct injection systems.
The engine driven transfer pump delivers fuel to the unit injectors via the secondary fuel filter. However, they were a favorite in the aforementioned competition trials in which essentially wide-open throttle operation was prevalent.
The pump is equipped with a pump-mounted safety v alve and th e fuel flow at rated rp m is listed in th e technic al data and varies with engine speed. Chevrolet introduced a mechanical fuel injection option, made by General Motors ‘ Rochester Products Divisionfor its V8 engine in U.
The most common automotive continuous injection system is Bosch’s K-Jetronicintroduced fuel injection system in diesel engine pdf download Power to the People”. All diesel engines with the exception of some tractors and scale model engines have fuel injected into the combustion chamber. Split-single I2 V2 F2.

The ECU interprets data from input sensors to, among other tasks, calculate the appropriate amount of fuel to inject. This was basically a high-pressure diesel direct-injection pump with an intake throttle valve. The circumferential velocity component is first generated as the propellant enters through helical or tangential inlets producing a thin, swirling liquid sheet.
The fuel meter adjusted the amount of flow according to engine speed and load, and included a fuel reservoir, which was similar to a carburetor’s float chamber. Caterpillar Switchgear Training Manual 3. This section needs additional citations for verification. A throttle position sensor TPS provides this information.
Nissan also installed multi-point fuel injection in the Nissan Y44 V8 engine in the Nissan President. Constant-flow injection systems continue to be used at the highest levels of drag racing, where full-throttle, high-RPM performance is key. Automobile emissions control Catalytic converter Diesel particulate filter Exhaust manifold Glasspack Muffler.
The pressure drop across the restrictions in the control unit controls the amount of fuel flow, so that fuel flow is directly proportional to the pressure at the flow divider.
Excerpts from the Rambler Rebel Owner’s Manual “. Continuous injection systems can be multi-point or single-point, but not direct. With its own high-pressure fuel pump driven by a cable downliad the distributor to the fuel meter, the system supplied the necessary pressure for injection.
