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. In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder.
The Kettering ignition system consisted of a single ignition coil, breaker points, a capacitor (to prevent the points from arcing at break) and a distributor (to direct the electricity from the ignition coil to the correct cylinder). [3] [4] [5] The Kettering system became the primary ignition system for many years in the automotive industry [6 ...
Low-speed pre-ignition ( LSPI ), also known as stochastic pre-ignition ( SPI ), [ 1] is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. [ 2] LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions. [ 3]
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 straight-6 Zephyr engine was used widely. Displacement began at 2.3 L; 137.8 cu in (2,258 cc) when it shared the same bore and stroke as the 1.5 L; 91.8 cu in (1,505 cc) 4-cylinder engine. It was produced with two standard compression ratios of 6.8:1 and 7.5:1 with outputs of 68 and 71 bhp (51 and 53 kW).
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 ...
The ignition coil is a transformer. The primary winding (called the low-tension winding in early texts) is connected to the battery voltage when the points are closed. Due to the inductance of the coil, the current in this circuit builds gradually. This current creates a magnetic field in the coil, which stores a quantity of energy.
