In a power control device for a vehicle in which an electric motor for driving the vehicle to travel is supplied with power from a battery mounted on the vehicle and a fuel cell, a control unit sets a target charging rate (SOCt) of the battery in such a manner that the target charging rate decreases as a remaining fuel amount (Qf) of the fuel cell decreases after the power generation of the fuel cell is started during high-output/high-speed travelling and controls a power generation output (Pf) of the fuel cell based on a difference between the target charging rate (SOCt) and a current charging rate (SOC).

Power control device for vehicle

Provided is a power control apparatus for a fuel cell vehicle which includes a fuel cell and which is driven by an electric motor that is supplied with electric power from the fuel cell. The power control apparatus includes an accelerator sensor that detects an operation of an accelerator, and a control unit that controls the fuel cell to increase the output power of the fuel cell so as to correspond to an increase in a requested acceleration output based on the detected accelerator opening degree. When the accelerator opening degree is less than a first accelerator determination value that is set in advance, the control unit controls the fuel cell to suppress an increase in the output power thereof.

Power control apparatus for fuel cell vehicle

A power controlling apparatus includes a secondary battery () connected to an electrical device (), and a fuel cell () connected to the electrical device () and the secondary battery (). The fuel cell () has two non-generating modes including an idling mode and a halt mode, the fuel cell () suspending generation of power while being supplied with fuel in the idling mode, the fuel cell () stopping generation of power without fuel supply in the halt mode. The power controlling apparatus further includes a remainder estimator () to calculate the remaining number of starts representing the remaining number of available starts of the fuel cell (), and a controller () to control the fuel cell () to be one of the two non-generating modes during a non-charging mode of the secondary battery (), based on the remaining number of starts calculated by the remainder estimator ().

Power controlling apparatus

An exhaust purification system includes a catalyst disposed in an exhaust path of an internal combustion engine; a fuel pump that supplies fuel to a common rail; an exhaust-side fuel injection valve that is interposed in the exhaust path so as to be located upstream of the catalyst and injects into the exhaust path the fuel supplied from the fuel pump; and estimation section that estimates a clogging degree of an injection port of the exhaust-side fuel injection valve on the basis of fluctuations in pressure of the common rail and those in revolution speed of the internal combustion engine at the time of fuel injection by the exhaust-side fuel injection valve.

Exhaust purification system for internal combustion engine

Control is performed such that when an HC adsorption catalytic converter having an oxygen storage capacity is in a specified temperature range, fuel supply quantity is increased with a first increase ratio relative to basic fuel quantity based on the operating state of an internal combustion engine, in a first specified period after the end of fuel cut, and increased with a second increase ratio smaller than the first increase ratio, in a second specified period succeeding the first specified period.

Emmision control device for internal combustion engine

A degradation estimating apparatus for an unburned fuel component adsorption catalyst, which is connected with an internal combustion engine and has an unburned fuel component adsorbent and an oxygen storage component is provided. The apparatus includes a degradation estimating unit for making estimation for a degradation of the unburned fuel component adsorption catalyst on the basis of a first term and a second term. The first term is from the cancellation of the fuel supply to detecting a variation of an upstream side air-fuel ratio occurring due to the increase of the reductant quantity in the exhaust gas. The second term is from the cancellation of the fuel supply to detecting of a variation of the downstream side air-fuel ratio due to an increase of the reductant quantity.

Degradation estimating apparatus for unburned component adsorption catalyst

The present invention provides an exhaust gas purifying catalyst that is capable of substantially reducing the degree of deterioration in an exhaust gas purifying capability, which results from dissipation of an absorbent agent. Accordingly, an exhaust gas purifying catalyst, which includes a carrier and a catalyst layer, and to which at least one material selected from a group of alkali metals and alkali earth metals is added as an absorbent agent, is characterized in that acid material with a high affinity with respect to the absorbent agent is mixed in the catalyst layer so as to fix the absorbent agent, and an inhibiting layer is formed between the catalyst layer and the carrier so as to inhibit the movement of the absorbent agent toward the carrier.

Exhaust gas purifying catalyst

An exhaust gas clean-up catalyst having a catalytic layer which contains, as an occluding agent, at least one (potassium and/or the like) chosen from a group consisting of alkaline metals and alkaline earth metals. The catalytic layer consists of a first catalytic layer ( ) which contains the occluding agent (potassium and/or the like) and an acid material ( ) having a high affinity to the occluding agent, and a second catalytic layer ( ) which contains the occluding agent and does not contain the acid material.

Catalyst for exhaust gas purification

It is an object of the present invention to provide an exhaust gas purifying catalyst formed as a single catalyst that has a great deal of flexibility when being assembled into an exhaust system and that is capable of executing both an NOx absorbing function and a three-way function in a desired manner. To attain the this object, an absorbent catalyst layer to which an absorbent agent such as potassium and an acid material such as zeolite are added, an absorbent agent block layer formed of zeolite, and a three-way catalyst layer to which an acid material such as phosphorus is added are bonded together on a cordierite carrier. The acid material in the absorbent catalyst layer and the absorbent agent block layer inhibit the movement of the absorbent agent to the three-way catalyst layer, and transform the absorbent agent into harmless and stable potassium phosphate even if the absorbent agent reaches the three-way catalyst.

In an exhaust gas purifying catalyst, an acid material with a high affinity with respect to an absorbing agent is dispersed and mixed in a catalyst layer, to which the absorbing agent is added, or a layer of the acid material is formed inside the catalyst layer in order to prevent the absorbing agent from moving from the catalyst layer into the carrier. This reduces the permeation of the absorbing agent added to the catalyst layer into a carrier, the evaporation and splash of the absorbing agent from the catalyst, and the deterioration in the durability and the exhaust gas purifying performance of the catalyst.

In a ceramic tip comprising a slipper block engaged by a cam arranged for rotation for causing opening and closing movement of an inlet valve on an exhaust valve of an engine, and a cast body block cast integrally with a valve rocker arm body, a round slope is formed at the conjoined boundary area between the slipper block and the cast body block to prevent occurrence of cracks, and retaining channels are formed on the cast body block to prevent escapement of the cast body block from the valve rocker arm body.
