Abstract
A method for operating an internal combustion engine used as a fuel which, special fuel characteristics, during combustion by compression ignition may achieve a favorable efficiency, and may provide consumption advantages over conventional combustion methods using conventional fuels. The fuel used may be straight-run naphtha, which is also known as raw gasoline. The fuel characteristics of this fuel are less expensive than conventional fuels, since expensive further treatment of the fuel may be dispensed with during production.
Claims17
A method for operating an internal combustion engine including intake valves, exhaust valves, a control device and a fuel-feed device, comprising:
- forming a fuel/air mix including fresh air and a fuel having a boiling range of 20 C to 190 C and an ignition performance of approximately 25 to 40 CN and introducing the fuel/air mix into a combustion chamber;
- and
- igniting the fuel/air mix.
