Method and equipment for control of an internal combustion engine with a fuel-reforming device wherein air passing through the fuel-reforming device is mechanically controlled depending on the volume of air to be sucked into the engine without passing through the fuel-reforming device and is supplied into the air not passing through the fuel-reforming device, upstream of a throttle valve by means of an air pump; the total air volume sucked into the engine is detected; and the volume of fuel matching the total air volume is electrically controlled so that it can be supplied upstream of the fuel-reforming device into the air passing through the fuel-reforming device, and if necessary, also into the air not passing through the fuel-reforming device.

Method and equipment for control of an internal combustion engine including a fuel-reforming device includes appropriate control of the ratio of total air to total fuel supplied to the internal combustion engine through mechanical regulation of the volume of air to pass through the fuel-reforming device in accordance with the volume of air to be sucked into the engine without passing through the fuel-reforming device, suction being done utilizing the negative pressure downstream of the throttle valve; through electrical regulation of the volume of fuel to be supplied to the air passing through the fuel-reforming device in accordance with the volume of the air; and through electrical control of a separate fuel-supply provided in the air path which does not run through the fuel-reforming device and of a fuel-supply which runs through the fuel-reforming device.
