[1] The company today marks its official starting date as 1903 when they started mass-producing carburetors for Henry Ford. [2] "Their first original carburetor, called the iron pot, appeared on the curved-dash Oldsmobile in 1904." [3] In April 1905 Holley Brothers Company was established with an address at 661-75 Beaubien St., Detroit ...
The fuel is injected only into the pre-chamber (where it begins to combust), and not directly into the main combustion chamber. Therefore, this principle is called indirect injection. There exist several slightly different indirect injection systems that have similar characteristics. [19] Types of indirect injection used by diesel engines include:
Early Lucas electronic diesel unit injector. A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and ...
Injection pump for a 12-cylinder diesel engine. An injection pump is the device that pumps fuel into the cylinders of a diesel engine.Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.
Gasoline does not provide the same level of lubrication for the injector components as diesel, which sometimes becomes a limiting factor in the injection pressures used by GDI engines. The injection pressure of a GDI engine is typically limited to approximately 20 MPa (2.9 ksi), to prevent excessive wear on the injectors.
The first win of a restrictor plate race during the fuel injection era would go to Matt Kenseth. [20] However, Kenseth simply could not keep the consistency to win any other restrictor plate race during the current fuel injection era. Roger Penske would become the first person to win the owner's championship while fielding cars with fuel injection.
Originally invented for Henry Fords six cylinder racer in 1905, the first production use of a CDI system was put into use in 1906 as standard equipment with the Ford Model K. The Model K utilized dual ignition systems, one of which was the Holley-Huff Magneto, or Huff System, manufactured by the Holley Brothers Company.
Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve , have mostly fallen out of favor to direct injection .
