摘要： A stop/start control device (20) applied to a spark ignition internal combustion engine (1). When stop conditions are established, the stop/start control device stops the internal combustion engine (1), and when the restart conditions are established, the stop/start control device restarts the internal combustion engine (1). While interrupting spark ignition of the internal combustion engine (1) in response to the stop conditions being established, the stop/start control device (20) allows fuel supply to the engine (1) to continue. When the restart conditions are established after the stop conditions are established and before the engine (1) completes its stop, the stop/start control device (20) restarts the engine (1) by restarting spark ignition of the engine (1) so that fuel supplied after the stop conditions are established combusts.

摘要： An engine system with a thermal storage device is capable of efficiently supplying heat from a thermal storage device to an internal combustion engine. The engine system (1) equipped with the thermal storage tank (100) supplies the hot water stored in the thermal storage tank (100) to a cylinder head (20a) of the internal combustion engine (20) before the starting thereof. At this time, an electronic control unit (90) sets a target value of the temperature of the internal combustion engine (20) at the start of the hot water supply in such a manner that the lower the temperature of the internal combustion engine (20), the lower does the target value become. As a result, a variation in combustion states between cylinders can be suppressed at the starting of the internal combustion engine (20).

摘要： An apparatus for detecting imbalance abnormality in an air-fuel ratio between cylinders in a multi-cylinder internal combustion engine comprises a turbocharger, a bypass passage, a waist gate valve, an air-fuel ratio sensor, and a stepless transmission. The imbalance abnormality is detected based upon a variation degree in output of the air-fuel ratio sensor. The internal combustion engine and the stepless transmission are controlled in such a manner that an actual operating point of the internal combustion engine moves on a predetermined operating line in a coordinate system defined by an engine rotational speed and engine torque. The operating line is changed in such a manner that, when the actual operating point is outside of a waist gate valve opening region at the time of detecting the imbalance abnormality, the actual operating point moves into the waist gate valve opening region.

摘要： A malfunction detection apparatus for detecting a malfunction in an evaporated fuel purge system in which fuel vapor from a fuel tank is adsorbed in an adsorbent in a canister and the adsorbed fuel vapor in the adsorbent is purged into an intake passage of an engine. The apparatus includes a detection part for detecting a concentration of fuel in the fuel vapor purged into the intake passage so that a change in the detected fuel concentration from a time when a purge cutting is performed to a time when a purging is performed after the purge cutting has been performed is detected, and a discrimination part for determining whether there is a malfunction in the system on the basis of the change in the detected fuel concentration by the detection part. The apparatus also includes a fuel vapor detection part for detecting a condition of fuel vapor in the fuel tank, and a purge cut time varying part for varying a purge cut time period for which the purge cutting is continuously performed, the purge cut time being varied by the purge cut time varying part in response to the detected fuel vapor condition by the fuel vapor detection part.
