  • Method for operating an internal-combustion engine
    Patent number: 6698402
    Abstract: In a method for operating an internal-combustion engine, a fuel/air mixture is fed to a combustion chamber of the internal-combustion engine and is ignited therein. At least for a defined period during the starting and/or warm-up of the internal-combustion engine, at least some of the liquid fuel is replaced with fuel which is in vapor form and is ignited in the at least one combustion chamber of the internal-combustion engine. The fuel which is in vapor form is taken from at least one fuel tank, which is connected to the internal-combustion engine, above a liquid-fuel level and/or from a charcoal canister which is connected to the fuel tank.

  • Method for shutting down and restarting individual cylinders of an engine
    Patent number: 5803040
    Abstract: The invention provides a method for shutting down and restarting individual cylinders of a multicylinder internal combustion engine by deactivating the charge change valves and the fuel injection. According to the invention, in shutting down a selected cylinder, the exhaust valve is disconnected first in all cases. Thereafter, the intake valve and fuel injection for the selected cylinder are controlled such that the last fuel injection into that cylinder takes place immediately before the last intake cycle. When a cylinder is restarted, the exhaust valve is always operated first, and only thereafter is the intake valve opened, with the first fuel injection always taking place immediately before the first intake cycle.
