Spontaneous combustion. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.
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.
