  2. Motronic - Wikipedia

    en.wikipedia.org/wiki/Motronic

    If the engine is naturally aspirated, an air temperature sensor is located in the air flow meter to work out the air mass. However, if the engine is turbocharged , an additional charge air temperature sensor is used to monitor the temperature of the inducted air after it has passed through the turbocharger and intercooler , in order to ...

  3. Timing light - Wikipedia

    en.wikipedia.org/wiki/Timing_light

    Timing light, combination instrument with RPM, volt meter and dwell angle meter. The actual light is on the far end. The black clamp connects to the battery -, the red clamp to +, the green one to the breaker side of the coil (for RPM), the big black clamp in the foreground is an inductive pick-up that clamps around a spark plug wire.

  4. Piston motion equations - Wikipedia

    en.wikipedia.org/wiki/Piston_motion_equations

    The reciprocating motion of a non-offset piston connected to a rotating crank through a connecting rod (as would be found in internal combustion engines) can be expressed by equations of motion. This article shows how these equations of motion can be derived using calculus as functions of angle ( angle domain ) and of time ( time domain ) .

  5. Dwell mechanism - Wikipedia

    en.wikipedia.org/wiki/Dwell_mechanism

    A single dwell linkage takes advantage of the behavior of a link with a stationary revolute (hinge) or prismatic (sliding) joint and its interaction with special coupler curves. There are two methods of producing a single-dwell: arc-based and linear-based. An arc-based single dwell linkage uses the approximation of a circular arc.

  6. Scotch yoke - Wikipedia

    en.wikipedia.org/wiki/Scotch_yoke

    The higher percentage of time spent at top dead centre (dwell) improves theoretical engine efficiency of constant volume combustion cycles. [4] It allows the elimination of joints typically served by a wrist pin, and near elimination of piston skirts and cylinder scuffing, as side loading of piston due to sine of connecting rod angle is ...

  7. Engine tuning - Wikipedia

    en.wikipedia.org/wiki/Engine_tuning

    Vintage engine testing equipment that can test ignition timing, ignition dwell, manifold vacuum and exhaust emissions. Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be ...

  9. 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.
