DEVICE AND PROCESS FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a device and a process for controlling an internal combustion engine (1) which can be operated with either a liquid or a gaseous fuel. A pressure reducer (4) and a low-pressure injection valve (6) are provided for use with the gaseous fuel. Monitoring devices are also provided which detect an increase in pressure which exceeds the limiting value in front of the low-pressure injection valve (6) when operating the internal combustion engine with liquid fuel, and trigger a drop in pressure by injecting the gaseous fuel.
