Fuel injection system for IC engines - has manifold accommodating nozzle and with outlet branches to individual combustion chambers

摘要

The fuel injection system has the nozzle discharge passage in the horn of the vibration amplifier. The nozzle discharge passage is normally shut by a valve movable in the lengthwise direction of the amplifier, and it opens only on injection. It has a manifold (1) accommodating the injection nozzle (9), together with a number of brances (2-5) emanating from the nozzle. The outlet of each branch is connected to one of the combustion chambers of the engine. The manifold can be an air inlet manifold with a throttle butterfly (7). The throttle butterfly can be situated between the nozzle and the manifold outlet branches.
