Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. [1] In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced ...
Engines with manifold injection, and an electronic engine control unit are often referred to as engines with electronic fuel injection (EFI). Typically, EFI engines have an engine map built into discrete electronic components, such as read-only memory. This is both more reliable and more precise than a three-dimensional cam.
In the system, air flow into the engine is measured by a moving vane (indicating engine load) known as the volume air flow sensor (VAF) — referred to in German documentation as the LuftMengenMesser or LMM. L-Jetronic used custom-designed integrated circuits, resulting in a simpler and more reliable engine control unit (ECU) than the D ...
With the Escort, the base engine was the same as all US Escorts, the 1.6L CVH, but featured unique intake and exhaust manifolds in addition to EFI. This was non-sequential EFI, meaning 1/4 of the required fuel for each cylinder was injected into the intake manifold, near the intake valve for each cylinder firing.
Driver input switches - cruise control, idle increase /decrease, engine/exhaust brake; Injector needle movement sensor - monitors the actual injection time and feeds the information to the ECU (as used on VM Motori 2.5 and 3.1 engines) Electronic Control Unit. EDC control unit. The ECU collects and processes signals from various on-board sensors.
Rochester Ramjet system installed on a 1957 Chevrolet 210. The Rochester Ramjet is an automotive fuel injection system developed by the Rochester Products Division of General Motors and first offered as a high-performance option on the Corvette and GM passenger cars in 1957.
The ramjet engine was designed by French engineer René Leduc. 1957: The first working prototype of the pistonless Wankel engine (sometimes called a rotary engine) is built by German engineer Felix Wankel. 1957: First usage of electronic fuel injection (EFI) in a production passenger car, using the American Bendix Electrojector system.
The 1.6 EFI shares the same head as the carbureted 1.6 found in North America but without a mechanical fuel pump. The 1.6 EFI engine was replaced by the 1.6 HO in all high-altitude regions, making the 1.6 EFI a rare model.
