Spark ignition definition

Spark ignition means relating to a gasoline, natural gas, or liquefied petroleum gas fueled engine or any other type of engine with a spark plug (or other sparking device) and with operating characteristics significantly similar to the theoretical Otto combustion cycle. Spark ignition engines usually use a throttle to regulate intake air flow to control power during normal operation. Dual-fuel engines in which a liquid fuel (typically diesel fuel) is used for compression ignition and gaseous fuel (typically natural gas) is used as the primary fuel at an annual average ratio of less than 2 parts diesel fuel to 100 parts total fuel on an energy equivalent basis are spark ignition engines.

Examples of Spark ignition in a sentence

  • Spark ignition engines usually use a throttle to regulate intake air flow to control power during normal operation.

  • Spark ignition engines are considerably less efficient than diesel engines, cancelling out most of the CO2- benefits from using natural gas instead of diesel.

  • Spark ignition engines use a spark (across a spark plug) to ignite the compressed fuel‐air mixture to create the motive force.

  • Spark ignition engines (Otto-cycle) use a spark plug to ignite a pre-mixed air fuel mixture introduced into the cylinder.

  • Spark ignition and initial phases of the combustion are reproduced accurately for all the three operating points by this simulation method.

  • Figure 6 presents this comparison for simulations without detailed mechanism (1-step mechanism) and with the three selected mechanisms after Spark ignition Timing (aST) till the end of spark discharge duration of 2 ms which are 18◦ CA for engine speed of 1500 rpm.

  • Spark ignition engine cycle simulation has been performed on the equivalent four stroke reciprocating engine of the AVRE engine, with approximately the same cylinder volume variation versus crank angle as this rotary engine.

  • Spark ignition testing of electric motors needs to be conducted under worst-case conditions.

  • The centre of combustion is kept constant at 8◦ CA after Top Dead Centre (aTDC) and hence, accordingly with the increase in the value of λ, Spark ignition Timing (ST) is advanced.
