Fluid injection system for IC engine - fluid is injected into inlet gas flow operated by pump controlled by pressure changes within combustion chamber

摘要

Fluid injection system into the suction airflow of an I.C. engine, includes a unit to determine the pressure changes in at least one combustion chamber of the motor and a pump which operates in accordance with the determined pressure changes and fitted with inlet and outlet pipes and with injection links (130) connected to the pump outlet to provide a fine spray injection of the fluid into the engine suction inlet gas flow. The pump is driven by the pressure changes within the combustion chamber in order to convey the fluid to the injection link (130).
