  2. Crankshaft position sensor - Wikipedia

    en.wikipedia.org/wiki/Crankshaft_position_sensor

    When it goes wrong, it stops transmitting the signal which contains the vital data for the ignition and other parts in the system. A bad crank position sensor can worsen the way the engine idles, or the acceleration behaviour. If the engine is revved up with a bad or faulty sensor, it may cause misfiring, motor vibration or backfires.

  3. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).

  4. Rotary encoder - Wikipedia

    en.wikipedia.org/wiki/Rotary_encoder

    A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. [1] There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle ...

  5. Switched reluctance motor - Wikipedia

    en.wikipedia.org/wiki/Switched_reluctance_motor

    The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .

  6. Engine control unit - Wikipedia

    en.wikipedia.org/wiki/Engine_control_unit

    The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...

  7. Dynamometer - Wikipedia

    The schematic shows the most common type of water brake, known as the "variable level" type. Water is added until the engine is held at a steady RPM against the load, with the water then kept at that level and replaced by constant draining and refilling (which is needed to carry away the heat created by absorbing the horsepower).

  8. Proton CamPro engine - Wikipedia

    en.wikipedia.org/wiki/Proton_CamPro_engine

    The first CamPro engine used in older Gen-2 models.. The first CamPro engine made its debut in 2004 fitted to the newly released Gen•2 models. It was codenamed S4PH and was a DOHC 16-valve 1.6-litre engine that produced 110 bhp (82 kW) of power at 6,000 rpm and 148 N⋅m (109 ft⋅lbf) of torque at 4,000 rpm.

  9. Resolver (electrical) - Wikipedia

    en.wikipedia.org/wiki/Resolver_(electrical)

    The two diphased windings are energized, the ratio between the sine and the cosine representing the electrical angle. The system turns the rotor to obtain a zero voltage in the rotor winding. At this position, the mechanical angle of the rotor equals the electrical angle applied to the stator. Differential resolvers
