  2. Rev limiter - Wikipedia

    en.wikipedia.org/wiki/Rev_limiter

    The RPM level that results with the spark timing being arrested can be a constant level, or, with the proper ignition control modules, variable. Variable rate ignition modules can be adjusted quickly and easily to achieve the appropriate RPM limit for different situations, such as street racing, drag racing, road course racing and highway driving.

  3. OBD-II PIDs - Wikipedia

    en.wikipedia.org/wiki/OBD-II_PIDs

    The third and fourth bytes are to be interpreted differently depending upon whether the engine is spark ignition (e.g. Otto or Wankel engines) or compression ignition (e.g. Diesel engines). In the second byte (B), bit 3 indicates the engine type and thus how to interpret bytes C and D, with 0 being spark (Otto or Wankel) and 1 (set) being ...

  4. Factory service manual - Wikipedia

    en.wikipedia.org/wiki/Factory_service_manual

    Chrysler manuals. Factory service manuals (FSM) are the manuals provided by manufacturers which cover the servicing, maintenance, and repair of their products. They are not designed for the general public, however they are created by manufacturers for use at their OEM dealerships.

  5. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.

  6. MegaSquirt - Wikipedia

    en.wikipedia.org/wiki/MegaSquirt

    This is an extension of the base code, adding many of the much needed MS1/Extra features to the MS-II chip. Enhancements include wide support for OEM crank/cam wheels, wasted spark and COP ignition, closed loop idle, EAE, boost control, nitrous control and many other features. Latest test codes support 4 cyl sequential fuel.

  7. Contact breaker - Wikipedia

    en.wikipedia.org/wiki/Contact_breaker

    A mechanism may be provided to slightly adjust timing to allow for varying load on the engine. Since these contacts operate frequently, they are subject to wear, causing erratic ignition of the engine. More recent engines use electronic means to trigger the spark, which eliminated contact wear and allows computer control of ignition timing.

  8. Standard Test Data Format - Wikipedia

    en.wikipedia.org/wiki/Standard_Test_Data_Format

    It is a commonly used format produced by automatic test equipment (ATE) platforms from companies such as Cohu, Roos Instruments, Teradyne, Advantest, SPEA S.p.A, and others. STDF is a binary format, but can be converted either to an ASCII format known as ATDF or to a tab delimited text file. Decoding the STDF variable length binary field data ...

  9. Auto reignition - Wikipedia

    en.wikipedia.org/wiki/Auto_reignition

    Auto reignition lowers the risk of gas leaks: if a flame goes out during operation, for example, from vibration or a gust of wind; due to misoperation—a user might not understand the "light" position must be maintained for about 0.5 to 2 seconds before turning the burner knob on fully.
