Difference between Contact breaker and Electronic ignitionsThe main difference between contact breaker and electronic ignitions is the way that they generate the spark that is needed to ignite the fuel in the engine’s cylinder. Contact breaker ignitions, also known as points ignitions, use a mechanical system to generate the spark. This system consists of a…

Retard is less amount of advance. Internal combustion engines need to start the combustion fire before the piston reaches TDC because it…
