ABSTRACT:
A multicylinder internal combustion engine, especially a self-igniting internal combustion engine, with supply ducts leading to the cylinders which supply ducts emanate from a common fuel supply chamber with the ducts being supplied with a fuel-gas mixture. The fuel-gas mixture is present in a mist form in the supply chamber with the fuel, with a substantially identical droplet size, exhibiting a droplet diameter at which a flow characteristic is obtained for the droplets in the ducts leading to the cylinders which is respectively at least approximately identical to the flow characteristic of the gas. The fuel is fed to the common supply chamber continuously by way of an injection device with the premixed fuel-gas mixture, which is at a pressure elevated with respect to the pressure level in the supply chamber, exiting from the injection device at a speed of sound with atomization of its proportion of fuel, on account of a pressure jump at a cross section of the discharge orifice of the injection device.
