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.
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 ...
Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic multi-point injection system for internal combustion engines. It has been available since the early 1980s. This system has been used in motorcycles, automobiles, and outboard motors.
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.
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 ...
It performs the same function as a conventional unit injector in an internal combustion engine, such as in an on-road or off-road vehicle or a diesel-electric locomotive. The pressurized delivery of fuel is camshaft -driven, but the timing of the injector's internal operations are controlled by the engine control unit so as to achieve certain ...
Business leaders warn of risks from inflationary tariffs and potential budget cuts at Goldman Sachs' Industrial and Materials conference.
The Lucas 14CUX (sometimes referred to as the Rover 14CUX) is an automotive electronic fuel injection system developed by Lucas Industries and fitted to the Rover V8 engine in Land Rover vehicles between 1990 and 1995. [1] The system was also paired with the Rover V8 by a number of low-volume manufacturers such as TVR, Marcos, Ginetta, and Morgan.
