Abstract
An installation for preheating the combustion air for the multi-fuel operation of air-compressing and auto-igniting injection-type internal combustion engines with poorly ignitable fuels, for example, gasoline, during idling and partial loads, which essentially consists of an injection nozzle for fuel and of a spark plug arranged in the suction pipe. The spark plug and injection nozzle are thereby combined into a structural unit as an insert body which includes a cover structure partially covering the spark plug and the injection nozzle while a protective plate member is provided in the path of the combustion air within the suction pipe for shielding the flame.
