  2. Firing order - Wikipedia

    en.wikipedia.org/wiki/Firing_order

    For this inline-4 engine, 1-3-4-2 could be a valid firing order.. The firing order of an internal combustion engine is the sequence of ignition for the cylinders.. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated.

    This was Chevrolet's second 4.3L power plant; four other Chevrolet engines displaced 4.3L: the Vortec 4300 (a V6 based on the Chevrolet 350 cu in (5.7 L), with two cylinders removed), the original 265 cu in (4.3 L) V8 in 1954, a bored version of the stovebolt-era 235 inline six displacing 261 cu in (4.3 L), and a derivative of the Generation II ...

  7. MAP sensor - Wikipedia

    en.wikipedia.org/wiki/MAP_sensor

    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).

  9. Chevrolet 90° V6 engine - Wikipedia

    en.wikipedia.org/wiki/Chevrolet_90°_V6_engine

    The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu. The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans.
