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
Ignition timing — in an internal combustion engine is the process of setting the time that a spark will occur in the combustion chamber (during the power stroke) relative to piston position and crankshaft angular velocity. Setting the correct ignition timing is… … Wikipedia
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
Ignition system — For other uses, see Ignition system (disambiguation). An ignition system is a system for igniting a fuel air mixture. Ignition systems are well known in the field of internal combustion engines such as those used in petrol (gasoline) engines used … Wikipedia
Mechanical fuel injection — Basic Concept of Mechanical Injection All forms of fuel injection (FI) are designed to achieve the delivery of a correct fuel/air mix into an internal combustion engine for the most fuel efficient burn. All forms of fuel injection do so by… … Wikipedia
