摘要： An engine control unit includes pressure detector provided in a combustion chamber of the engine. A motoring pressure of the engine is estimated. A combustion starting time is detected when the difference between an internal pressure detected by the pressure detector and the pressure estimated by the ECU exceeds a predetermined value. When the internal pressure detected by the pressure detector reaches its peak after the combustion starting time has been detected, the crank angle at this time point is determined to correspond to the maximum internal cylinder pressure that is generated by combustion.

摘要： A combustion state detecting apparatus is provided for an engine having internal pressure sensor for detecting an internal pressure of a combustion chamber of the engine and crank angle detector for detecting a crank angle of the engine. The apparatus calculates a volume of the combustion chamber based on the crank angle detected by the crank angle detector and estimator for estimating a motoring pressure of the engine in accordance with a calculation equation using the calculated volume. The apparatus adjusts either of the pressure detected by the internal pressure sensor and the pressure estimated by the estimator during a compression stroke of the engine to minimize the error between the detected pressure and the estimated pressure. The apparatus determines a combustion state during a combustion stroke of the engine based on a relation between the pressure adjusted and the other pressure. The apparatus identifies parameters of the calculation equation during a compression stroke of the engine to minimize the error between the pressure detected by the internal pressure sensor and the pressure estimated by the estimator.

摘要： A failure diagnosis apparatus for a throttle valve actuating device is disclosed. The throttle valve actuating device has an actuator for actuating a throttle valve provided in an intake system of an internal combustion engine and biasing elements for biasing the throttle valve to a predetermined retention opening. A feedback control of the throttle valve is performed so that an opening of the throttle valve coincides with a first predetermined opening. After the throttle valve is controlled to the first predetermined opening, a feedback control of the throttle valve is performed so that an opening of the throttle valve coincides with a second predetermined opening. It is determined that the throttle valve actuating device has failed when the time period during which the opening of the throttle valve remains in a predetermined determination range including the second predetermined opening, is shorter than a predetermined time period when performing the feedback control to the second predetermined opening.

摘要： A vehicle fuel gas supply system includes a fuel line supplying a fuel gas to a gas engine, a shut-off valve and a pressure sensor disposed on said fuel line, and a control section. The pressure sensor is disposed closer to said gas engine in comparison with said shut-off valve. The control section closes the shut-off valve being opened, starts to count the time of a shut-off valve closing timer. Then, the control section opens the shut-off vale when the shut-off valve closing timer counts up, simultaneously therewith measures a pressure by the pressure sensor to store the pressure as an initial pressure, and starting to count the time of a diagnostic timer. Further, the control section measures a second pressure by the pressure sensor when the diagnostic timer counts up to store the second pressure as a final pressure value, and judges that the shut-off value is in a failure state when a pressure increase rate obtained from the initial pressure value and the final pressure value is smaller than a predetermined pressure increase rate threshold value.

摘要： A system for controlling an air/fuel ratio of an internal combustion engine, including a feedback control loop having an adaptive controller (STR controller) that receives as inputs a desired value r and a controlled variable y output from the plant (engine) and an adaptation mechanism that estimates adaptive parameters. The STR controller calculates a feedback correction coefficient KSTR, as an output u based upon at least the adaptive parameters, for correcting a basic amount of fuel supply calculated by retrieving mapped data, prepared beforehand, such that the controlled variable y converges to the desired value r. The system is configured such that the controlled variable y is determined based upon the detected air/fuel ratio KACT and a desired air/fuel ratio KCMD so that the desired value r is a predetermined value. More specifically, the controlled variable is determined to be a ratio between the detected air/fuel ratio and the desired air/fuel ratio such that the desired value r is 1.0 or thereabout. With this arrangement, when the desired air/fuel ratio is changed or corrected frequently, the estimation of the adaptive parameters is not affected, thereby improving the stability of air/fuel ratio control.

摘要： A system for purifying exhaust gas generated by an internal combustion engine including a bypass branching out from the exhaust pipe downstream of a catalyst and merging to the exhaust pipe, an adsorber installed in the bypass, a bypass valve member which closes the bypass, and an EGR conduit connected to the bypass at one end and connected to the air intake system for recirculating the exhaust gas to the air intake system. The bypass valve member is opened for a period after engine startup to introduce the exhaust gas such that the adsorber installed in the bypass adsorbs the unburnt HC component in the exhaust gas. The adsorber adsorbs the HC component when the exhaust temperature rises and the adsorbed component is recirculated to the air intake system through the EGR conduit. In the system, the bypass valve is provided at or close to the branching point in the exhaust pipe and a chamber is provided close to the branching point such that the conduit is connected to the bypass at the one end in the chamber. The bypass valve member is combined with an exhaust pipe valve member as a combination valve such that when the bypass valve member closes the bypass, the exhaust pipe valve member opens the exhaust pipe. With the arrangement, the system can effectively prevent the exhaust pipe from being clogged even when a valve for closing a bypass is stuck in the closed position. At the same time, the system can provide a relatively short EGR conduit for recirculating unburnt HC component adsorbed from the adsorber and the adsorption and desorption are conducted optimally.

摘要： An air-fuel control system for use with an internal combustion engine has a catalytic converter, a first exhaust gas sensor, and a second exhaust gas sensor. A sliding mode controller determines a correction quantity to equalize the concentration of the component downstream of the catalytic converter to a predetermined appropriate value based on the output from the second exhaust gas sensor. A feedback controller determines a correction quantity to converge the concentration of the component downstream of the catalytic converter toward the predetermined appropriate value, and feed-back controls the rate at which fuel is supplied to the engine with the determined correction quantity. The sliding mode controller has a hyperplane setting unit for establishing a hyperplane for the sliding mode control process with a linear function having as variables a plurality of quantities of the exhaust system which include at least the concentration, detected by the second exhaust gas sensor, of the component of the exhaust gas downstream of the catalytic converter and a rate of change of the concentration, and a calculator for determining the correction quantity to correct the air-fuel ratio of the internal combustion engine so as to converge the state quantities onto the established hyperplane and also to converge the state quantities toward a balanced point on the established hyperplane while converging the state quantities onto the hyperplane. The hyperplane setting unit variably establishes the hyperplane depending on the manner in which the state quantities converge onto the hyperplane.
