The rapid transition from a non-conducting to a conductive state produces a brief emission of light and a sharp crack or snapping sound. A spark is created when the applied electric field exceeds the dielectric breakdown strength of the intervening medium.
SI (Spark Ignition) engine- Combustion in engine happens due to the spark given by spark plug to ignite the fuel i.e. spark ignition engine. GDCI ( Gasoline Direct Combustion Ignition)- Combustion happens by compression of gasoline by a lean mixture (14.8:1). This eliminates spark plug.
