In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
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 iron ...
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.
General Motors did not meet two specific requirements — torque required and vibration environment — for the ignition switch. The torque, or rotational power that prevents the ignition switch from changing modes, was required to be between 10 N·cm and 20 N·cm (Newton centimeters).
The TVR Cerbera is an example of a car with factory-fitted sports exhausts which produce frequent backfires on engine braking. In high-powered supercharged aircraft piston engines such as the Rolls-Royce Merlin and Griffon , backfiring into the inlet manifold is prevented with flame traps inside the manifold, the traps preventing the flame ...
What about self-driving cars? While most automakers are still focused on optimizing lower-level advanced safety tech like forward collision mitigation and lane departure prevention, full ...

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.
