摘要

A suction air heater for an air-compressing injection-type internal combustion engine which includes a spark plug and fuel injection nozzle arranged in an air suction pipe and an electric motor driving a fuel pump; an oil pressure switch controlling the operation of the heater is provided in the internal combustion engine which assures that energy is supplied to the electric motor when the engine is running; a temperature-dependent switch is series-connected with the oil pressure switch for selectively opening or closing the circuit of the electric motor while a starter switch may be connected in parallel with the oil pressure switch.
