Spark plugs ignite the mixture of petrol/autogas (LPG) and air produced by the carburettor or injection system. The resulting explosion pressure is the basis for starting the engine. Autogas (LPG) has an ignition temperature of ~500°C, petrol only ~350°C. Therefore a higher energy is needed for the ignition of the gas mixture than with a pure gasoline mixture. In order to avoid stressing the ignition coil of conventional spark plugs and to prevent premature ignition coil failure, the use of special "LPG spark plugs" is recommended.
These „LPG spark plugs“ differ from conventional „petrol spark plugs“ by a reduction of the electrode gap and the electrode treatment with special precious metals (e.g. platinum or iridium). This compensates the ignition voltage requirement and protects against premature wear.
