Abstract
A method is provided for operating an internal combustion engine that includes, but is not limited to ascertaining a possible instant of a stoppage of the internal combustion engine and injecting fuel to fill a cylinder of the internal combustion engine. The injection performed shortly before the instant of the stoppage of the internal combustion engine.
Claims20
A method for operating an internal combustion engine, comprising:
- ascertaining a possible instant of a stoppage of the internal combustion engine;
- and
- injecting fuel to fill a cylinder of the internal combustion engine shortly before the instant of the stoppage of the internal combustion engine.
A method for operating an internal combustion engine, comprising:
- monitoring a curve of a parameter of a crankshaft of the internal combustion engine,
- storing the curve of the parameter of the crankshaft over a defined minimum measuring period of time;
- extrapolating the curve of the parameter of the crankshaft for a decelerating crankshaft;
- and
- determining an angle of the crankshaft upon an extrapolated stoppage of the crankshaft.
A control unit for operating an internal combustion engine, comprising:
- an input port configured to receive measured values about a parameter of a crankshaft of the internal combustion engine;
- a storage unit configured to store a time curve of the parameter of the crankshaft of the internal combustion engine;
- a computer unit configured to calculate a possible instant of a stoppage of the internal combustion engine upon an extrapolated stoppage of the crankshaft;
- and
- an output port configured to control a fuel supply and control an ignition of a cylinder of the internal combustion engine.
A computer readable medium embodying a computer program product, said computer program product comprising:
- an operating program for operating an internal combustion engine, the operating program configured to:
- ascertain a possible instant of a stoppage of the internal combustion engine;
- and
- inject fuel to fill a cylinder of the internal combustion engine shortly before the instant of the stoppage of the internal combustion engine.
A computer readable medium embodying a computer program product, said computer program product comprising:
- an operating program for operating an internal combustion engine, the operating program configured to:
- monitor a curve of a parameter of a crankshaft of the internal combustion engine,
- store the curve of the parameter of the crankshaft over a defined minimum measuring period of time;
- extrapolate the curve of the parameter of the crankshaft for a decelerating crankshaft;
- and
- determine an angle of the crankshaft upon an extrapolated stoppage of the crankshaft.
