what causes a car engine to vapor lock
Vapor lock The fuel can vapourize due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude. In regions where fuels with higher volatility are used during the winter to improve engine startup, continued use of the specialized fuels during the summer can cause vapour lock to occur more readily.
Ignition coil Where coils are individually applied per cylinder, they may all be contained in a single molded block with multiple high-tension terminals. This is commonly called a coil-pack.
Catalytic converter As an alternative, catalytic converters were moved to a third of the way back from the engine, and were then placed underneath the vehicle.
Fire Once ignited, a chain reaction must take place whereby fires can sustain their own heat by the further release of heat energy in the process of combustion and may propagate, provided there is a continuous supply of an oxidizer and fuel.
