Abstract: An electric power storage system 10 of the present invention includes a lithium secondary battery; a detection device to detect the temperature of the lithium secondary battery; and a control device to decrease a remaining capacity of the lithium secondary battery based on an increase of the detected temperature and a temperature Tbx of the lithium secondary battery. When a self-heating rate of the lithium secondary battery at a temperature T (K) and a remaining capacity x (%) is represented by Hs(x, T) (K/min), and a heat dissipation rate at a temperature T (K) of the lithium secondary battery is represented by Hd(T) (K/min), the temperature Tbx is a temperature at which Hs(x,Tbx)>Hd(Tbx) holds. That is, this temperature Tbx is a temperature at which the heat generating rate is higher than the heat dissipation rate and at which the battery temperature T starts to increase.

Abstract: Provided is a fitting adjustment structure for a lid in which, before a frame and a lid are incorporated into an opening portion, a height of a stopper can be adjusted with the lid being closed, to thereby eliminate the need for adjustment after the incorporation. The fitting adjustment structure for the lid includes: the opening portion formed on a panel; the lid which turns to open and close the opening portion; and the frame which is placed along a periphery of the opening portion, and supports the lid, in which: a screw hole is pierced in the frame; a stopper having an upper surface which abuts against a rear surface of the lid in a closed state is screwed with the screw hole; and a turning operation portion engageable with a rotating tool is provided at a lower end of the stopper.

Abstract: A four-bar linkage is provided with an opened position holding mechanism. The opened position holding mechanism includes: an engagement pin which protrudes in a rear end portion of a second hinge arm; a support pin which protrudes in a base end portion of an extending portion of a link bracket; a hook bracket having a central portion which is turnably supported by the support pin; and an urging spring which pulls the hook bracket in one direction with respect to the support pin as the center. The hook bracket includes: a guide surface; and an engagement concave portion to be engaged with the engagement pin. The guide surface hits against the engagement pin in accordance with a lid opening operation, and a hit position therebetween relatively moves in a central direction in accordance with a turn with respect to the support pin as the center performed against the pulling force of the urging spring.

Abstract: An air-fuel ratio control apparatus estimates, on the basis of an exhaust air-fuel ratio of exhaust gas flowing into an exhaust purifying catalyst unit disposed in an exhaust passage of an engine, an emission of at least one specific component contained in exhaust gas flowing out of the exhaust purifying catalyst unit. The air-fuel ratio control apparatus performs the estimation by use of a model, and controls the air-fuel ratio in such a manner that the estimation value reaches a target state. The model is previously determined in consideration of the mass balance of the specific component.

Abstract: An exhaust gas purification system comprises a NOx catalyst for absorbing the NOx in the exhaust gas when the air-fuel ratio of the influent exhaust gas is lean and purifying by reducing the absorbed NOx with a reducing agent in the exhaust gas when the air-fuel ratio of the exhaust gas turns rich, a first unit for calculating the amount of NOx absorbed per unit time in each area of the NOx catalyst when the air-fuel ratio of the exhaust gas flowing into the NOx catalyst is lean, and a second unit for calculating the total amount of NOx absorbed into the NOx catalyst by totaling the amounts of NOx calculated by the first calculation unit for the areas of the NOx catalyst.

Abstract: A catalytic emission control apparatus of an internal combustion engine that has an engine stop mode of stopping the internal combustion engine during a run of a vehicle utilizes an oxygen absorption-storage action of an emission control catalyst disposed in an exhaust passage of the internal combustion engine. The emission control apparatus has a storage computing device that computes a storage of oxygen in the emission control catalyst, and air-fuel ratio controller performs an air-fuel ratio control of the internal combustion engine based on the storage of oxygen computed by the storage computing device. The storage computing device computes the storage of oxygen during the engine stop mode of the internal combustion engine. The air-fuel ratio controller performs the air-fuel ratio control when the internal combustion engine is restarted after the engine stop mode is discontinued, based on the storage of oxygen computed by the storage computing device during the engine stop mode.
