Abstract
A fuel injection device comprises electrically controlled fuel injectors, each opening into an air induction passage upstream of a respective intake valve of a combustion chamber. Each injector has an air-fuel mixture chamber. A throttle valve in the induction passage is constructed to close it when in a minimum opening position. An air line connects the induction passage to the mixture chambers and has an additional air electrically controlled valve. A supplemental electrically controlled valve is branched out of the line and opens into the induction passage downstream of the throttle valve. An electronic unit controls the injectors and the supplementary valve and opens the supplemental valve during cold start of the engine at low temperature and during operation of the engine as a brake at normal temperature, high speed and with the throttle valve closed.
