An automatic aircraft powerplant control system includes a throttle servo for adjusting a throttle valve via a throttle control linkage. A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A propeller servo may be provided for adjusting a propeller governor setting of an engine. A propeller control lever provides a user input to the propeller servo, and a propeller controller controls the propeller servo. A full-authority digital engine control (FADEC) controller is used to automatically control mixing of fuel and air via a fuel-air mixture device. The FADEC controller may be used to automatically provide propeller control.

A control apparatus includes a throttle configured to adjust an amount of air flowing in an intake passage of an engine, an accelerator opening sensor configured to detect an accelerator opening, a throttle opening sensor configured to detect an opening of the throttle, and a control unit configured to control the opening of the throttle. The control unit includes a setting unit configured to set a target opening and set a control amount of the throttle based on a deviation between the target opening and the opening detected by the throttle opening sensor, and a correction unit configured to, if the target opening is not more than a predetermined opening, set a correction amount of the control amount such that the opening of the throttle becomes large independently of the deviation.

A vehicle includes an engine, a second MG for running, a battery that supplies and receives electric power to and from the second MG, and an ECU. The ECU is configured to control the engine and the second MG and to execute intake air amount learning. When the SOC of the battery exceeds a second threshold value that is higher than a first threshold value while the vehicle is running using the second MG with the engine in a stopped state, the ECU maintains the engine in the stopped state and maintains the second MG in a driven state, and then does not execute the intake air amount learning. When the SOC of the battery takes a value between the first threshold value and the second threshold value, the ECU starts the engine, drives the second MG with constant torque, and executes the intake air amount learning.

A spark ignition type engine adjusts a base lower limit value of a valve opening degree of an ISC valve to avoid excessive engine rotation that may occur when an increase correction by atmospheric pressure is performed. When a detected engine temperature becomes lower, the base lower limit value of the ISC valve opening degree is increased to the fully open side, and the base lower limit value is corrected to increase to the fully open side with an increase correction value on the basis of a detected atmospheric pressure in an engine middle-high temperature range where the engine temperature exceeds a predetermined value, and the increase correction value is increased to the fully open side as the detected atmospheric pressure becomes lower, and the increase correction is prohibited in an engine low temperature range where the engine temperature is equal to or lower than the predetermined value.

An electrically-operated actuator rotates a valve toward its closing side or opening side. A valve urging part urges the valve from a fully-closed position toward the opening side. An ACT control part controls the electrically-operated actuator to drive. A set load of the valve urging part is smaller than a set load that is capable of returning the valve from a fully-closed position to an intermediate position only by urging force of the valve urging part. When a position of the valve at time of turning off an IG switch for stopping operation of an internal-combustion engine is on the closing side of the intermediate position, the ACT control part shifts the valve to the intermediate position by the electrically-operated actuator after the IG switch is turned off.

Systems and methods for operating an engine that includes two throttles that are arranged in parallel to deliver air into a single intake manifold are described. In one example, a first throttle and a second throttle are opened according to a value of a variable that changes as a function of a requested engine air flow.
