Abstract: Provided is an apparatus and a method for controlling an internal combustion engine such that emissions may not worsen during recovery from a fuel cut. An internal combustion engine control apparatus executes feedback control on the air-fuel ratio of an internal combustion engine. The control apparatus increases a supply of fuel, with the air-fuel ratio feedback stopped, when combustion restarts after a fuel cut of the internal combustion engine. The control apparatus sets the air-fuel ratio criteria based on a rich-side peak value of the air-fuel ratio obtained after the fuel supply increase starts. The control apparatus starts the air-fuel ratio feedback when the air-fuel ratio falls within the set air-fuel ratio criteria after the fuel supply increase.

A determination process determines that wear has occurred on a gear mechanism in the throttle device based on a parameter related to a change speed of an angular position in a specific range during execution of the driving process. The specific range is a range from a specific angular position to the initial position. The specific angular position is the angular position that is separated from the initial position by a predetermined constant angle.

Abstract: The internal combustion engine includes a first oil jet that injects oil toward an inflow hole for flowing oil into the cavity, and a second oil jet that injects oil to a back surface so that the oil does not flow into the cavity. The control device of the internal combustion engine determines whether the temperature of the piston is equal to or higher than a specified temperature which is a threshold value for determining whether the piston has overheated to the extent that cooling is required. When the temperature of the piston is equal to or higher than the specified temperature, the control device cools the piston by using the first oil jet. When the temperature of the piston is lower than the specified temperature, the control device restricts the injection of the oil from the first oil jet and warms up the oil using the second oil jet.

Abstract: The invention is to utilize one radiator instead of two to cool two separate vehicle cooling systems. The main embodiment is a single radiator cooling system that partitions the physical radiator into two separate surface areas that are dedicated for each of the two respective circuits. A processor can control an actuator that drives a screw and plunger mechanism to push and pull a plunger. The plunger separates the two surface areas so as the plunger is moved, a corresponding surface area is increased or decreased for a cooling circuit. An increase in the surface area can provide more cooling for that circuit as the fluid has more core area to travel through. Temperature sensors can provide data to a processor that can adjust the actuator to provide cooling relief to the circuit where its most required.
