An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed . [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.
A water in fuel sensor, or WiF sensor, is an electronic sensor used to indicate the presence of water in fuel.It is installed in a fuel filter.When the water level in the water separator reaches the warning level, the WiF sends an electrical signal to the ECU or to dashboard (lamp). [1]
In 1981, a Delco Electronics ECU was used by several Chevrolet and Buick engines to control their fuel system (a closed-loop carburetor) and ignition system. [10] By 1988, Delco Electronics was the leading producer of engine management systems, producing over 28,000 ECUs per day.
A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine" Graphical tell-talesA tell-tale, sometimes called an idiot light [1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
Unlike the pushrod systems used by DaimlerChrysler's Multi-Displacement System and General Motors' Active Fuel Management, Honda's VCM uses overhead cams. A solenoid unlocks the cam followers on one bank from their respective rockers, so the cam follower floats freely while the valve springs keep the valves closed. The system operates through ...
The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU).
EK31 engine of Subaru 360. The 360 featured an air-cooled, two-stroke inline 2-cylinder 356 cc engine mounted transversely at the rear, and was introduced March 3, 1958. [2]As with many other small two-stroke gas-engined cars, oil needed to be premixed with the petrol (gasoline), with the fuel tank lid serving as a measuring cup.
EICAS typically includes instrumentation of various engine parameters, including for example speed of rotation, temperature values including exhaust gas temperature, fuel flow and quantity, oil pressure etc. Other aircraft systems typically monitored by EICAS are for example hydraulic, pneumatic, electrical, deicing, environmental and control ...
