An ignition process obeys the law of ______________
View Answer Explanation
The pressure, temperature and density of the mixture between the spark plug electrodes have a considerable influence on the __________ required to produce a spark.
If the spark energy exceeds 40 mJ and the duration is longer than 0.5 ms, reliable ignition is obtained.
If the resistance of the deposits on the spark plug electrodes is sufficiently high, the loss of electrical energy through these deposits may prevent the spark discharge.
As air is poor conductor of electricity an air gap in an electric circuit acts as a high _____________
A spark is produced to ignite a homogeneous air fuel mixture in the combustion chamber of an engine, it is called spark ignition system.
An ignition system should provide a good spark between the _____________ of the plugs at the correct timing.
An ignition system should function efficiently over the entire range of engine speed.
An ignition system should be heavy, effective and reliable in service.
An ignition system should be compact and easy to maintain.
An ignition system should be cheap and convenient to handle.
