  • Patent number: 11319885
    Abstract: A vehicular internal combustion engine system includes an internal combustion engine and an electric intake air supply device. The internal combustion engine is shifted into a stoichiometric combustion mode, and a lean combustion mode. The electric intake air supply device is driven by an on-vehicle battery, and employed to contribute a part of intake air quantity at least under a specific operating condition when in the lean combustion mode. A control method includes: determining a requested electric energy of the electric intake air supply device for a shift into the lean combustion mode in response to a shift from a stoichiometric combustion operation region into a lean combustion operation region; and continuing the stoichiometric combustion mode, without operation of the electric intake air supply device, when the on-vehicle battery is in an insufficient state of charge with respect to the requested electric energy.

  • Patent number: 11313313
    Abstract: When a rotational speed of an engine is higher than a predetermined rotational speed, a low-pressure fuel injection valve is controlled through the use of a fuel injection time based on an estimated fuel pressure in a low pressure supply pipe and a target fuel injection amount. When the rotational speed of the engine is equal to or lower than the predetermined rotational speed, the low-pressure fuel injection valve is controlled through the use of a fuel injection time based on a detected fuel pressure input from the fuel pressure sensor from the issuance of a command to activate energization of a solenoid to the start of energization of the solenoid and a target fuel injection amount.

  • Patent number: 11280289
    Abstract: An internal combustion engine is equipped with a downstream temperature sensor arranged in an intake passage, an upstream temperature sensor arranged in the intake passage upstream of the downstream temperature sensor, an EGR temperature sensor arranged in an EGR passage, and an airflow meter arranged in the intake passage. A control device corrects a temperature detected by each of the temperature sensors based on an amount of deviation of the temperature detected by that one of the temperature sensors upon activation of the control device after the lapse of a prescribed time or more since stoppage of the internal combustion engine from a reference temperature. Then, the control device calculates a flow rate of EGR gas based on the corrected temperature of that one of the temperature sensors and a flow rate of intake air, and detects the clogging of the EGR passage based on the flow rate.

  • Patent number: 11274613
    Abstract: A control system and method relating to operation of an internal combustion engine, particularly an engine for powering an unmanned aerial vehicle. The engine has a combustion chamber and a throttle for regulating fluid flow to the combustion chamber, the throttle being operable under the control of an electronic control unit. With the control system and method there are first and second modes optionally available for operation of the engine. In the first mode the engine is operable at a throttle setting set by a request from a first remote controller (e.g. a ground-based controller) via a second on-board controller. In the second mode the engine is operable at a prescribed minimum throttle setting asserted by the electronic control unit which limits the authority of the on-board controller. The engine is caused to operate in the second mode if a particular throttle setting determined from a request of the remote controller is less than the prescribed minimum throttle setting.
