File Bosch A Type Injection Pump 001 Jpg Wikimedia Commons Mechanical Fuel Injector

Mechanical fuel injection works with a simple throttle-controlled air valve and a fuel pump, usually running at one-half engine speed. After pulling fuel from a vented fuel tank, the fuel is delivered through a barrel valve that controls the amount of fuel with the position of the air valve. Bosch developed an electronic fuel injection system, called D-Jetronic (D for Druck, German for "pressure"), which was first used on the VW 1600TL/E in 1967. This was a speed/density system, using engine speed and intake manifold air density to calculate "air mass" flow rate and thus fuel requirements. Bosch Mechanical Fuel Injection is a splendid, if not inexpensive, performance induction system. It was used on the 911S and 911E from 69 to 73 as well as the 73 Carrera RS. Porsche used various types of MFI on factory racing cars from 67 to 84. PLEASE NOTE This tester will also work with older Porsche and other European cars that used the Bosch mechanical fuel injection system from the 1960's. This kit will work on the fuel injectors from the 6.3 V8 but it WILL NOT WORK on the 3.5 and 4.5 V8 engines (those used electronic fuel injectors. Bosch Port Fuel Injectors (PFI) have a robust design and are capable of using Ethanol fuel (E100). All Bosch fuel injectors released to the aftermarket are OE fit, form and function, and are produced to OE specifications. The Bosch fuel injector has a return rate of 1 part per million (PPM), making Bosch the industry benchmark. Jetronic is a trade name of a fuel injection technology for automotive petrol engines, developed and marketed by Robert Bosch GmbH from the 1960s onwards. Bosch licensed the concept to many automobile manufacturers. There are several variations of the technology offering technological development and refinement. Bosch Classic, Remakes, Fuel injector.

Bosch supplied the industry’s first fuel injection system with a high pressure electric fuel pump in 1967. Since then, Bosch has stood at the forefront of fuel system technology, providing fuel pumps to virtually all vehicle manufacturers.
