The linear regulator (3) of the error signal (delta s) gives an output (alpha'') which is compensated and filtered (4) for subtraction (6) from the actual accelerator pedal signal (5),(alpha-actuell). The diffe
Since the sensor has a high response, the output of the sensor oscillates as shown by the dot-dash line of FIG. 7, because of the pulsation of the intake air induced in the cylinders of the engine. Heretofore, the output Qs is averaged to obtain an intake air quantity Qs'. In the f...

(2) hold under the condition that the air-fuel ratio is the theoretical air-fuel ratio, the EGR rate equals zero, the warming-up operation of the engine is finished (i.e., the oil-water temperature is a predetermined value or more), and the opening/closing timing of the intake valve ...
(PWC) have been widely used in leisure, sport, rescue activities, and the like. The personal watercraft is configured to have a water jet pump that pressurizes and accelerates water sucked from a water intake generally provided on a bottom of a hull and ejects it rearward from an outlet ...
The accelerator position sensor 2 and the vehicle speed sensor 3 supply electric signals indicative of the sensed accelerator position AP and the sensed vehicle speed V to the ECU 1. Also connected to the ECU 1 is an actuator 4 for driving a throttle valve 5 arranged in an intake pipe, no...
5.The catalyst temperature calculating apparatus according to claim 2, wherein the physical parameter used by the temperature estimating unit is at least one of measured values of an outside air temperature sensor, an engine coolant sensor, an intake-air temperature sensor, and an exhaust emission...
17. A cylinder intake air quantity calculating apparatus for an engine, comprising: a detecting section that detects a camshaft rotational phase based on output of a sensor, wherein the camshaft rotational phase at this a time when an engine speed is below a predetermined level is substituted wi...
