    摘要： A dual component injector, especially for internal combustion engines, has a nozzle body, which has a nozzle outlet, and a valve needle for opening and closing the nozzle outlet. A first feed channel is used for supplying a first fluid to the nozzle outlet, and a second feed channel is used for supplying a second fluid to the nozzle outlet. Optionally, a fluid chamber, which is located in the nozzle body, is connected to the nozzle outlet. The second feed channel is connected to the fluid chamber or to the first feed channel via at least two bored holes. The bored holes open out in the fluid chamber or in the first feed channel in such a way that the second fluid produces a swirling flow pattern in the fluid chamber or in the first feed channel.

    摘要： An internal combustion engine has a preparation device for fuel, for the purpose of providing a starting fuel which comprises low-boiling fuel constituents. A catalytic converter is accommodated in an exhaust train of the internal combustion engine. After-treatment of the exhaust gases is carried out by a secondary air device, by means of the combustion being carried out with an excess of starting fuel for rich-burn operation during the cold start and the subsequent warm-up phase. The system is provided for spark-ignition mixture-compressing or spark-ignition direct injection internal combustion engines.

    摘要： A fuel fractionation device is provided for separating a low-boiling fuel fraction from a liquid fuel in an internal combustion engine, having a fuel tank which contains the liquid fuel and having a separator, to which an extracted fuel fraction mixture can be fed, and a reservoir to which the fuel fraction can be fed, and furthermore having a pump which extracts fuel vapor and air and has a pump drive. The pump and the pump drive are fixed in a housing and are accommodated removably in the fuel tank together with the separator and the reservoir, forming a structural unit.
