A vehicular control device includes a determining unit configured to determine whether an absolute value of a steering angle as a rotation angle of a steering wheel exceeds a first threshold value, an estimating unit configured to estimate a lithium deposition amount as an amount of lithium metal deposited on the lithium-ion battery by regenerative current flowing into the lithium-ion battery, based on vehicle information obtained from the vehicle, when the determining unit determines that the absolute value of the steering angle exceeds the first threshold value, and a reporting command unit configured to give a command to report that the vehicle is in a first state, based on the lithium deposition amount estimated by the estimating unit.

Vehicular control device, control method, non-temporary storage medium, and vehicle

A carbon monoxide selective oxidizing catalyst includes a carrier of ferrierite or ZSM-5 that supports a metal component of platinum (Pt) alone or platinum and at least one type of transition metal. Alternatively, a carbon monoxide selective oxidizing catalyst includes a carrier whose maximum pore diameter ranges from 0.55 to 0.65 nanometers (nm) that supports a metal component of platinum (Pt) alone or platinum and at least one type of transition metal.

Carbon monoxide selective oxidizing catalyst and manufacturing method for the same

An exhaust-gas-purifying catalyst wherein a first zeolite loaded with a catalyst metal and a second zeolite unloaded with a catalyst metal are mixed. By actively adsorbing HC onto the second zeolite, it is possible to inhibit the catalyst metal loaded on the first zeolite from being poisoned by HC, and to sufficiently adsorb HC. Accordingly, since the HC adsorbing capability is improved, and since the HC poisoning of the catalyst metal is suppressed, the NO purifying capability is enhanced and the durability is also upgraded.

Exhaust emission control catalyst

In an exhaust gas in an oxygen-rich atmosphere, a method of purifying an exhaust gas and a catalyst for purifying an exhaust gas, which can exhibit a high NO,conversion securely, are provided. Disclosed is a method of purifying an exhaust gas that reduces and purifies NO,in an exhaust gas in an oxygen-rich atmosphere. Here, as a catalyst for purifying an exhaust gas, a loading layer comprising zeolite is loaded with alumina sulfate and cerium sulfate-zirconium composite oxide, and Pt is loaded on these. And, in a temperature range where HC are not oxidized, the HC are adsorbed and held by the zeolite, the HC, which the zeolite releases at the temperature increment, are subjected to cracking by the zeolite, the alumina sulfate and the cerium sulfate-zirconium composite oxide, and the thus produced low-grade HC are turned into reducing agents, thereby reducing and purifying the NO,in the exhaust gas.
