Abstract
Improvements in electrically controlled injection installations, for internal combustion engines, of the poly-cylinder type with electromagnetic injection valves associated with the different cylinders, of which half in each case is assembled forming a group of simultaneously actuated valves, and with an electronic control device that is connected to the crankshaft turns compass to open the valves of at least one of the groups, and is disconnected after a duration determining the injection quantity, depending on at least one parameter of service of the internal combustion engine, especially its quantity of intake air, characterized in that a switch is available in the installation that can be operated by the throttle valve of the internal combustion engine in the area of its idle speed position, which at the throttle valve is open, causes an action Simultaneous operation of both valve groups, and when the throttle valve is closed or almost closed, it causes an alternative actuation of one of the valve groups in each case.
