ignition timing — It is important that the spark coming from the spark plugs ignites the air fuel mixture at the correct moment determined by the manufacturer of the engine. Often this is a few degrees before top dead center (BTDC). Suppose the specs indicate that … Dictionary of automotive terms

static ignition timing — An obsolete timing procedure carried out by rotating the engine until the timing marks are aligned and then connecting a test lamp or a voltmeter between the negative coil terminal and ground; when the points open, the test lamp lights up or the… … Dictionary of automotive terms
timing — One of the essential factors in a internal combustion engine (Fuel, Air, Proper proportion of mixture, compression Timing, spark). When the piston is in the compression stroke both valves must be closed. If one or more is open, the valve timing… … Dictionary of automotive terms
ignition — A process which initiates the combustion of the compressed air/fuel mixture in the combustion chamber. In a spark ignition engine, the mixture is ignited by an electric spark; in a diesel engine, the self igniting mixture must be preheated by… … Dictionary of automotive terms

Homogeneous Charge Compression Ignition — Homogeneous Charge Compression Ignition, or HCCI, is a form of internal combustion in which well mixed fuel and oxidizer (typically air) are compressed to the point of auto ignition. As in other forms of combustion, this exothermic reaction… … Wikipedia
Compression ratio — For compression ratio in data compression, see data compression ratio. The compression ratio of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its… … Wikipedia
