Abstract: A removal determination device that accurately determines a removal of an exhaust gas purification device from an exhaust pipe. The removal determination device comprises: an input temperature sensor detecting a temperature at an upstream side of casing; an output temperature sensor detecting a temperature at a downstream side of the casing; an engine stop time collector measuring a time period from an inactivation of an engine to a startup of the engine; and a determiner determining a presence of the exhaust gas purifying device based on the input temperature and the output temperature, in a case that the time period is equal to or longer than a predetermined time.

Abstract: An engine starting system for starting an engine promptly during propulsion without reducing a drive force. When a condition to crank the engine is satisfied during propulsion in a neutral stage, torque is applied to an input rotary element to crank the engine by reducing a rotational speed of a control rotary element by increasing a torque capacity of a first engagement device to utilize an inertial force of the free rotary element as a reaction force.

Abstract: A vehicle control system, in which that maintains a reaction force against the backward movement of a vehicle while preventing an overheating of a motor due to phase lock of the motor. When a thermal load on a specific phase of the motor exceeds a threshold value, a controller execute a phase shift control to reduce a thermal load on a specific phase of the motor by changing a rotational angle of the motor, while interrupting torque transmission between the motor and wheels and generating the torque to stop the vehicle by the actuator.

Abstract: In an internal combustion engine, a hydrocarbon feed valve (15), NOx storage catalyst (13), particulate filter (14), and electric resistance type sensor (29) are arranged in an engine exhaust passage in this order from an upstream side. The electric resistance type sensor (29) generates an output value corresponding to the amounts of deposition of particulate matter and hydrocarbons which are contained in the exhaust gas and deposited at the sensor part thereof. From the change of the output value of the electric resistance type sensor (29), it is judged if the hydrocarbons have slipped through the NOx storage catalyst (13) and if the particulate matter has slipped through the particulate filter (14).

Abstract: A controller is provided for an engine comprising urea-SCR catalyst, a urea-water supply section, a low pressure gas recirculating section including a low pressure EGR pipe forming a low pressure EGR passage and a low pressure EGR valve. The controller controls an amount of a fuel supplied to the engine, and an opening degree of the low pressure EGR valve. The controller supplies the urea-water to the urea-SCR catalyst in such a manner that an ammonia flowing out from the urea-SCR catalyst neutralizes an acid condensed water produced by a gas passing through the low pressure EGR passage.

Abstract: An internal combustion is configured such that a hydrocarbon supply valve (15) and an exhaust gas purification catalyst (13) are arranged in an engine exhaust gas passage and such that NOx contained within exhaust gas is purified by spraying hydrocarbon from the hydrocarbon supply valve (15) at predetermined intervals. When SOx is to be released from the exhaust gas purification catalyst (13), the air-fuel ratio of exhaust gas which flows into the exhaust gas purification catalyst (13) is enriched by generating, within a cylinder, combustion gas having a rich air-fuel ratio, and after that the air-fuel ratio of exhaust gas which flows into the exhaust gas purification catalyst (13) is enriched by supplying hydrocarbon from the hydrocarbon supply valve (15).

Abstract: In an internal combustion engine, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged in an engine exhaust passage. As rich control for making the air-fuel ratio of the exhaust gas which flows into the exhaust purification catalyst (13) rich, cylinder rich control for generating rich air-fuel ratio combustion gas in the cylinder and exhaust rich control for feeding hydrocarbons from the hydrocarbon feed valve (15) to make air-fuel ratio of the exhaust gas rich are used. When the air-fuel ratio of the exhaust gas which flows into the exhaust purification catalyst should be made rich, if the speed of the vehicle is lower than a predetermined speed and the gear position of the transmission is at a predetermined low speed gear position, exhaust rich control is used instead of cylinder rich control.

The control section controls, based on an engine operating parameter, “an amount of a fuel supplied to the engine, and an opening degree of the low pressure EGR valve.” The control section supplies the urea-water to the urea-SCR catalyst in such a manner that ammonia of an amount required for reducing nitrogen oxides contained in an exhaust gas in the urea-SCR catalyst is produced in the urea-SCR catalyst (urea-water for reducing nitrogen oxides supply control).

Abstract: A control device includes first means and second means for recirculating exhaust gas from an exhaust passage toward an intake passage. When first recirculated gas amount recirculated by first means for recirculating exhaust gas is changed to a target amount, the control device compensates for the difference of the first recirculated gas amount during a period from a start time of change to an end time of change by increasing or decreasing the second recirculated gas amount recirculated by second means for recirculating exhaust gas, according to a predetermined control pattern. When an actual amount of index related to the recirculated gas amount that is a constituent included in the exhaust gas and an amount of the constituent vary depending on total amount of the exhaust gas does not match a referential amount of the index, the control pattern is corrected to decrease the difference of the index that is a difference of the actual amount with reference to the referential amount.
