Engine control apparatus

TL;DR: A throttle valve controller achieves high output response to the smaller deviation of the actual opening from the demand opening of the throttle valve and achieves high control stability against the larger deviation as discussed by the authors.

TL;DR: In this paper, a throttle control apparatus includes a throttle opening degree sensor for detecting the degree of opening of the throttle valve and an engine operating condition detecting device is used to detect an operating condition of the engine.

TL;DR: A throttle control system comprises a throttle valve disposed within an air intake duct of an engine, a direct current motor connected to the throttle valve, and a throttle angle sensor, throttle open angle command value deriving unit, motor load condition detecting unit for detecting a load condition on the direct-current motor, rounding unit for moderating variation of the open-angle command value depending upon the load condition of the directcurrent motor as discussed by the authors.

TL;DR: In this paper, a method for controlling a throttle of an electronic throttle control-equipped engine is presented, which includes the steps of providing a desired throttle position derived from the driver demand and vehicle system requests.

TL;DR: In this article, a device for reducing longitudinal dynamic instabilities of vehicles, in particular back and forth movements of cargo (load) and the uncontrolled periodic feeding of gas having, for the purpose of damping, a differentiation device (8) which differentiates an electric signal of the engine speed of rotation, preferably a voltage.

TL;DR: An active Wien-Robinson suppression filter connected as electrical filter in the electric transmission line from a drive-pedal potentiometer of a motor vehicle to the adjusting member of the throttle valve of the internal combustion engine can be avoided with the use of such a filter as discussed by the authors.

TL;DR: An installation for damping periodically alternating longitudinal accelerations of a motor vehicle is also designated as jerking movements and which occur, above all, in motor vehicles whose internal combustion engines are equipped with electronic fuel injection systems and have a high torque already in the lower rotational speed as discussed by the authors.

TL;DR: In this article, an arrangement for regulating the idling rotational speed of an internal combustion engine includes a comparison stage which compares the actual and the desired rotational speeds, an idling operation filling regulation device connected to the output of the comparison stage, including at least a proportional region, and controlling an electrically manipulated adjustment member for the adjustment of the amount of intake air in the throttling damper.
