Abstract: A control device for an internal combustion engine comprising a combustion control part controlling a fuel feed system and ozone feed system so as to form a difference in ozone concentration space-wise or time-wise in a combustion chamber 11 so that premixed gas burns by compression ignition in stages in the combustion chamber and an ozone malfunction judging part judging malfunction of the ozone feed system. The ozone malfunction judging part judges that the ozone feed system is malfunctioning when the self-ignition timing is retarded from the presumed self-ignition timing and the combustion noise is larger than the presumed combustion noise or when the self-ignition timing is advanced from the presumed self-ignition timing and the combustion noise is smaller than the presumed combustion noise.

The spool valve includes an axially extending internal passage fluidly connected to a fluid volume at the front end of the spool valve, and a control port at the back end of the spool valve, selectively alignable to fluidly connect the ports. Two springs of different lengths either alone or together, bias the spool valve toward opening of the inlet check valve.

Abstract: A starter is installed in a vehicle. In the starter, a crank shaft is driven by a motor which rotates a pinion gear in a state where a ring gear connected to the crank shaft is in engagement with the pinion gear. Thus, an engine is started. The starter sets a start-up period depending on the type of the start-up trigger that generates a start-up request for the engine, and sets a current supplied to the motor on the basis of the set start-up period. Thus, at least either of a rotation speed and an output torque of the motor is controlled. This control is implemented by a control circuit.

Abstract: A method for a model-based determination of a cylinder charge of a combustion chamber of an internal combustion engine as well as an internal combustion engine in a computer program product. The method utilizes a neuronal network having at least three input values. A pressure quotient is used as one of the input values. The pressure quotient is determined as the ratio of the pressure of the air set by the engine over the operating pressure of the engine. The pressure of the air set by the internal combustion engine may be determined by utilizing a measured value, a computed value, and/or a value determined from a characteristic map. It is also possible to include a combination of these in the pressure quotient.

Abstract: In some embodiments, a vehicle includes a temperature monitoring controller. The temperature monitoring controller is a processor, control module, or other suitable hardware that is configured to receive temperature sensor values from an engine control module (ECM) when an ignition bus is in a powered on state, and to decide when the engine should be automatically started in order to maintain a temperature above a low temperature threshold. The temperature monitoring controller periodically causes an ignition bus of the vehicle to be placed in the powered on state when the engine is shut down in order to collect temperature sensor values. The temperature monitoring controller determines whether to automatically start the engine, and if not, determines how long to wait before collecting temperature sensor values again based on a rate of change of the temperature sensor values.
