An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
An ignition coil is used in the ignition system of a spark-ignition engine to transform the battery voltage to the much higher voltages required to operate the spark plug(s). The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. The ignition coil is constructed of two sets of coils wound around an iron ...
Incorrect or out of specification fuel can cause problems or severe damage to the engines and associated equipment. [1] The effects may include: corrosion, abrasive wear, clogged cylinder valves, fuel equipment damage, fuel pump failure, premature ignition, ignition failure, explosion, or engine failure. [1]
The most famous aftermarket electronic ignition which debuted in 1965, was the Delta Mark 10 capacitive discharge ignition, which was sold assembled or as a kit. The Fiat Dino was the first production car to come standard with EI in 1968, followed by the Jaguar XJ Series 1 [ 9 ] in 1971, Chrysler (after a 1971 trial) in 1973 and by Ford and GM ...
The ignition switch was designed to remove power from the vehicle's airbags when in the Off or Accessory mode. [11] Therefore, this was a safety hazard: If the switch changed from Run to Accessory and the vehicle was involved in an accident, it would no longer have power to release the airbags, and it would be difficult for the driver to steer ...
Later models have the TFI module mounted on a heatsink in the engine compartment. It is prone to damage from heat. It was created with surface-mount technology parts, allowing it to be much smaller than the previous Dura-Spark ignition module. The ignition coil used is the E-Core design.
In March 1948, the service (now the USAF) ordered four more aircraft under the new designation XG-18A and a fifth to be fitted with engines as the YC-122.The air force eventually lost interest in purchasing assault gliders, but continued with the development of the powered variant, purchasing two more examples for evaluation as the YC-122A and redesignating the second of these as the YC-122B ...
