2. Spark plug - Wikipedia

   en.wikipedia.org/wiki/Spark_plug

   Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...

3. Gasoline direct injection - Wikipedia

   en.wikipedia.org/wiki/Gasoline_direct_injection

   The spark plug must be placed in such a way, that it is exactly in the zone where the mixture is ignitable. ... They estimate the annual social cost of these ...

4. Ignition timing - Wikipedia

   en.wikipedia.org/wiki/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 compression stroke.

5. Internal combustion engine - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine

   Just before the piston reaches TDC, ignition begins. In the case of a SI engine, the spark plug receives a high voltage pulse that generates the spark which gives it its name and ignites the charge. In the case of a CI engine, the fuel injector quickly injects fuel into the combustion chamber as a spray; the fuel ignites due to the high ...

6. Reciprocating engine - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_engine

   Ray-traced image of a piston engine. There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, either already under pressure (e.g. steam engine), or heated inside the cylinder either by ignition of a fuel air mixture (internal combustion engine) or by contact with a hot heat exchanger in the cylinder (Stirling engine).

8. Spark-ignition engine - Wikipedia

   en.wikipedia.org/wiki/Spark-ignition_engine

   Spark-ignition engines are commonly referred to as "gasoline engines" in North America, and "petrol engines" in Britain and the rest of the world. [1] Spark-ignition engines can (and increasingly are) run on fuels other than petrol/gasoline, such as autogas (), methanol, ethanol, bioethanol, compressed natural gas (CNG), hydrogen, and (in drag racing) nitromethane.

9. National Ignition Facility - Wikipedia

   en.wikipedia.org/wiki/National_Ignition_Facility

   This is normally in the form of a small plutonium "spark plug" in the center of the fuel. Nuckolls's idea was to explore how small the secondary could be made, and what effects this would have on the energy needed from the primary to cause ignition. The simplest change is to replace the LiD fuel with DT gas, removing the need for the spark plug.
