Abstract: PROBLEM TO BE SOLVED: To ensure the HC removing operation of an exhaust device of an engine for vehicle which is equipped with a layer of HC adsorbing material and a layer of exhaust gas purifying catalyst having an oxygen holding ability, whereby the HC in the exhaust gas is adsorbed to an HC adsorbant layer by passing the exhaust gas through the HC adsorbant layer when the engine is starting in cold condition, the adsorbed HC is separated from the HC adsorbant layer by passing the exhaust gas through the HC adsorbant layer after the engine is warmed up, and the separated HC is turned into H2O and CO2 by oxygen held in the catalyst layer to be exhausted. SOLUTION: The exhaust device of an engine for vehicle is equipped with a first means to judge the oxygen holding condition of the exhaust gas purifying catalyst layer and a second means to suppress the feed of exhaust gas for HC separation to the HC adsorbant layer when the judgement by the first means is such that the oxygen holding condition of the catalyst layer has not attained the specified degree.

Abstract: PROBLEM TO BE SOLVED: To comply with a reciprocal relationship between a temporal stop of an engine and the maintenance of an exhaust emission purifying catalyst activation temperature for keeping the exhaust emission purifying catalyst activation temperature while preventing the reduction in an engine temporal stop effect of an economy running system vehicle or a hybrid vehicle. SOLUTION: If a temperature of the engine exhaust emission purifying catalyst is lowered below a lower limit threshold necessary for keeping its purifying function when the engine temporal stop is allowed according to a vehicle operation condition and carried out, the engine is operated for heating the catalyst even if the engine temporal stop is allowed among the vehicle operating conditions. If the catalyst temperature reaches a predetermined higher limit threshold the engine operation for heating the catalyst can be stopped.

Abstract: PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of restraining deterioration of fuel cinsumption to the minimum while restraining degradation of a catalyst. SOLUTION: The control device for the internal combustion engine to control an air-fuel ratio stoical or rich by supplying fuel at the time of deceleration in a catalyst high temperature state while stopping fuel supply at the time of deceleration not in the catalyst high temperature state constitutes its characteristic feature of providing a sudden decelerating state detection means to detect a sudden decelerating state large in deceleration and a fuel supply prohibition means to prohibit fuel supply at the time when the sudden decelerating state is detected by the sudden decelerating state detection means even at the time of deceleration in the catalyst high temperature state. The sudden decelerating state detection means is to detect the sudden decelerating state having possibility to cause fuel supply stoppage to be carried out in the case when injection time of less than the minimum injection time free to inject by an injector.

Abstract: PROBLEM TO BE SOLVED: To provide a cooling control device for an internal combustion engine capable of sufficiently cooling the internal combustion engine in a hybrid vehicle. SOLUTION: In the case of the engine temperature of an internal combustion engine 1 being higher than the specified temperature when driving driving wheels 6 using only the driving force of an MG 3, a control device 11 controls power dividing mechanism 4 to forcibly drive the internal combustion engine 1 by an MG 2 or the MG 3, or sets a change-over operating condition to an operating condition low in engine speed or vehicle speed, or stops fuel supply to a fuel injector 14 at higher engine speed to stop fuel supply to the internal combustion engine 1 and rotates the internal combustion engine 1.

Abstract: PROBLEM TO BE SOLVED: To efficiently regenerate heating by providing multiple granular exhaust emission control members arranged in a prescribed zone of an exhaust passage, heating its near position by heating means, and circulating the members so as to bypass the vicinity of the heating member. SOLUTION: Net members 3, 4 are arranged on a pipe enlarging part 2 arranged in an exhaust passage 1 so as to form a zone 5, and multiple granular exhaust emission control members 10 are arranged in the zone 5. In the zone 5, a heater 6 is fixed to an inner wall of a pipe enlarging part 2, and a heater side end part of the net member 3 is substituted to a shield wall 7. Also, the other end part of the net member 3 is substituted to a push-pressing member 8 freely to rotate around a rotary shaft 8a. When pressure of exhaust gas is increased, the push-pressing member 8 is rotated upward, and the grain shaped exhaust gas purifying members 10 arranged in the vicinity of the push-pressing member 8 are pushed up in a nearly upper direction. All granular exhaust emission control members 10 are passed near the heater 6, and are heated and regenerated.

Abstract: PROBLEM TO BE SOLVED: To make channel connection efficient in a system where a center collects information from a vehicle and serves the information to other vehicle. SOLUTION: A permissible information generating section 300a of a center 300 monitors a channel use rate of a satellite 100 and generates permission information that inhibits connection to an area with a high channel use rate or adjusts a connection time when the channel use rate reaches a prescribed rate or over and the section 300a transmits the information to the satellite 100. A transmitter 100b of the satellite 100 transmits simultaneously the permission information to vehicles 200. The vehicle 200 receiving the permission information discriminates whether or not the transmission of its own vehicle and transmits information collected by a sensor 200d to the center 300 via the satellite 100 when the transmission is permitted. The center 300 processes the information and transmits the processed information to other vehicles.
