Abstract

A valve for injecting a fuel/gas mixture that includes a perforated body, which comprises an upper thin plate and a lower thin plate, both of which are for instance embodied of monocrystalline silicon. At least one conduit is formed between the upper thin plate and the lower thin plate, by way of which conduit the gas meets the fuel injected through the at least one injection port. It is unnecessary to adjust the metered gas quantity. The perforated body and the valve are particularly suitable for injection systems in mixture-compressing internal combustion engines with externally supplied ignition.
