HILBORN Fuel Injection has been a leader in the design and implementation of mechanical fuel injection for over 65 years. The cam lobes rolling on the cage cause the plunger to reciprocate and rotate simultaneously, building the high pressure for injection. An essential tool for diagnosing many fuel injection problems inclding leaking or clogged injectors, fuel rail deterioration, clogged fuel filter and fuel pump malfunction. The electrically controlled common-rail fuel system provided maximum power for each pulse of fuel used and allowed full authority in injection timing and quantity. It covers from older mechanical to the most modern electronic ignition system, such as DIS, Waste-Spark, COP, CSI on GM-Saab and most ignition systems separated by engine type. The Fuel Pressure Regulator is a must have item for any EFI system, without it, the fuel rail will not be able to build up enough pressure to support the injectors with the sufficient amount of fuel, the fuel will instead flow straight through and not reach the injectors. This essentially is a system where one or two fuel injectors are located in the throttle body itself. The engine-driven systems comprise a fuel-injection pump with an integrated governor. We put the first fuel injected Harleys into the 9's, 8's and 7's at the drag strip and are looking to put one into the sixes in the near future. Each one is calibrated to deliver just the right quantity of fuel via the fuel injector into the combustion chamber. The Bosch VE pump is primarily found on compact and automotive diesel engines.

There is fuel to the injector pump, its gravity fed and flows freely, but nothing comes out of the pump (I have the lines to the injectors disconnected. Electronic fuel injection metering, when properly designed and programmed, is today’s accurate way to introduce fuel to an internal combustion engine. Earlier Bosch/Mercedes mechanical fuel injection systems included direct, timed, high pressure injection into the cylinder (DB600 series V-12s and some racing engines) timed, indirect medium pressure injection before the intake valve, and semi-timed (fewer injection pumps than cylinders, with paralleled injection lines) as before. Porsche used various types of MFI on factory racing cars from 67 to 84. Whenever the fuel system has been opened up for service (lines disconnected or filters removed), it will be necessary to bleed air from the system. An electronic controller converts the fuel information sent from the ECU into mechanical control of the fuel delivery by opening and closing fuel spill ports inside the pump mechanism. Several fuel injection manufacturers and flow bench services report that there does not seem to be any power advantage with fuel pressures over 100 psi in conventional stacker injection systems. AM General Corporation MILITARY HMMWV M998A1 Series Vehicles Component Testing and Troubleshooting 5715434. Designing and Tuning High-Performance Fuel Injection Systems. Turbo system, it is necessary to make an adjustment to the fuel injection pump. There may be various reasons for a malfunctioning fuel pump. The fuel tank must also be properly vented. high pressure central fuel injection and GM, Ford, and Chrysler multi-port fuel injection. Engines using indirect injection generally have lower levels of knock than direct injection engine, due to the greater dispersal of oxygen in the combustion chamber and lower injection pressures providing a more complete mixing of fuel and air. FUEL SYSTEM N/A Closed-Loop Electronic Fuel Injection HORSEPOWER (KW) 22. The high-pressure mechanical fuel pump, which is driven by one of the engine’s camshafts, is supplied by a conventional, ­single-line, in-tank pump. Keywords: diesel engine, diesel fuel injection system, simulation Abstract The injection process of a medium-speed diesel engine was studied in detail, using a computer program developed for this purpose. These allow for greater fuel efficiency and economy as different factors are taken into consideration to determine the correct amount of fuel to put into each cylinder. The fuel cell is much more than a place to store fuel before it is delivered to the engine. Gas admission is activated when combustion is stable in all cylinders. Diesels actually do not suffer exactly the same "knock" as gasoline engines since the cause is known. Kia makes reasonable efforts to ensure that information contained in its press releases is accurate at the time of posting. Initially developed for two-stroke direct injection gasoline engines, the solenoid-actuated electronic high-pressure fuel injector became available in the late 1980s and was soon adopted for the development of. HILBORN Mechanical Fuel Injection HILBORN Fuel Injection has been a leader in the design and implementation of mechanical fuel injection for over 65 years.

Volkswagen Transporter (Air-cooled) Petrol 1979 - 1982 manual covers: Transporter with air-cooled flat-four engines 1979 - 1982. Fuel has to be pumped from the fuel tank to the engine, and it has to be delivered under low pressure to the carburetor or fuel injectors. It won't be as good as a modern fuel injection system like Motec, but it will work. The electronic control unit determines how long the injector stays open. THE DUAL FUEL ENGINE In this case, the normal diesel fuel injection system still supplies a certain amount of diesel fuel. No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication. Diesel Fuel Injection Pumps. the fuel injection regulator via two filtered turbocharger inlets mounted on the rear engine baffles which feed compressed (turbocharged) air to a common intercooler mounted an the engine fire wall. The spray from a fuel injector can be continuous or intermittent. Our staff has over 75 combined years of mechanical injection experience, ranging from a basic 1 cylinder application to turbo charged V-12 monsters, so we can design the ideal system for your racing application. 2 Figure 2 shows the main components in the Lucas Mark Il petrol injection system.

Also included are diagnosis and replacement of related starting and charging system components. A regular addition of fuel system cleaner like STP Injector Cleaner, or Techtron fuel system cleaner can help keep your injectors clean. Fuel injection systems run at a fairly high pressure, typically 43. Systems competence:A higher injection pressure requires more than just a re-engineered injector. Bosch supplied the industry’s first fuel injection system with a high pressure electric fuel pump in 1967. This Self-Study Program concerns the design and function of the new pump injection system, and the modifications to the fuel system, engine management system, and engine mechanical components to accommodate the system. Fuel injection isn't new technology—it's been around almost as long as the internal combustion engine and was used in aircraft engines as far back as World War I.
