An exhaust emission control system of an internal combustion engine is provided which controls the oxygen concentration of exhaust passing through the exhaust emission control device according to the flow rate of exhaust flowing through an exhaust passage when the exhaust emission control device is regenerated, so that the regeneration is completed within a short period of time while the filter is prevented from being damaged by melting during the regeneration. This improves the exhaust emission control performance and reliability of the filter.
摘要:
An exhaust emission control system of an internal combustion engine capable of post injection is disclosed which provides control such that the injection timing in sub injection is set to a point earlier than the target injection timing when the sub injection is started, and the injection timing in the sub injection is then delayed to the target injection timing. This realizes the post injection under the optimum conditions and enables an efficient rise in the exhaust temperature while inhibiting deterioration of the drivability due to a rapid change in torque.

A crankcase of an internal combustion engine includes protruding portions formed on an outer surface of the crankcase which are constituted of a pair of left and right wall members, and a vibration isolating rubber is fitted between the wall members. The crankcase configured in this manner prevents the generation of sounds from a protruding portion of the crankcase and is light-weight.

A hydraulic clutch for preventing a drag of a clutch at the time of disengaging the clutch by decreasing an oil supply quantity between a plurality of clutch plates and a plurality of clutch discs thus decreasing a change hitting sound at the time of shifting. A hydraulic clutch is configured such that the superposition between an oil supply hole formed in a clutch pressure plate and an oil supply hole formed in a clutch center becomes maximum when the clutch is engaged.

A secure electronic inserter. A picture analyzer 3 analyzes an input picture 101, and decides the insertion strength of the electronic water marking to be inserted, from one pixel of the input picture 101 to another, to output the insertion strength information 104 to an electronic watermark pattern inserter 1 and to a shifting information pattern inserter 2. The electronic watermark pattern inserter 1 inserts an electronic watermark pattern 105, stored in an electronic watermark pattern storage unit 4, into the input pattern 101. The key information pattern inserter 2 inserts the key information pattern 106, stored in the key information pattern storage unit 5, into a picture to be processed 102, having the inserted electronic watermark pattern, in accordance with the insertion strength information 104, to output the resulting picture.

An exhaust structure for a fuel cell vehicle includes a fuel cell for generating electrical power by inducing a reaction between hydrogen and oxygen and, a motor to generate motive power for supply to the rear wheel functioning as the drive wheel based on the electrical power generated by the fuel cell and, an exhaust pipe to convey byproducts in the fuel cell power generation process and, an exhaust port formed on the exhaust pipe opening towards the outer side of the vehicle frame, wherein the exhaust port is positioned more to the rear with respect to the front end of the rear wheel, and more specifically is formed further to the rear with respect to the rear wheel drive shaft. The exhaust structure so configured for fuel cell vehicles is capable of preventing byproducts from the fuel cell from reaching the drive wheel, even when struck by the wind, or when changing the turn radius.

A variable compression ratio engine includes a control actuator which has a simple structure, seals well internally, and provides high reliability. In the variable compression ratio engine, a connecting rod is divided into at least two portions. A control rod is operatively connected to a juncture of the connecting rod. A support shaft position of the control rod is displaced. The control rod is operatively connected to a right cylinder rod of a piston-type double-acting hydraulic control cylinder. A piston section of the hydraulic control cylinder is configured to selectively move in accordance with displacement of the support shaft position of the control rod. A channel is used to connect two hydraulic chambers divided by the piston section. The channel is configured to selectively control the flow of hydraulic fluid from the right hydraulic chamber to the left hydraulic chamber, and vice versa.

A process for producing an ion exchange resin having a specific surface area of at least 0.04 m.sup.2 /g, an ion exchange resin produced by the process, and a method for removing ionic and noinionic impurities from a condensate by means of the ion exchange resin produced by the process. The process comprises the steps of: (1) uniformly imbibing a monomer mixture comprising a bifunctional unsaturated aromatic monomer and a monofunctional unsaturated aromatic monomer into aromatic crosslinked copolymer particles comprising a monofunctional unsaturated aromatic monomer and a bifunctional unsaturated aromatic monomer and having a porosity of not more than 0.2 ml/g; (2) polymerizing the monomer mixture in the presence of a polymerization initiator; and (3) introducing an ion exchange group into the resulting copolymer particles. The ion exchange resin has a large specific surface area and high physical strength and is capable of removing both ionic and noinionic impurities from a condensate.
摘要:
A fuel cell two-wheel vehicle is provided with: a fuel cell, fuel tanks, a supercharger, a pipe line, an in-wheel motor, and a motor driver. The fuel cell generates electric power using hydrogen and air as reaction sources. The fuel tanks supply hydrogen to the fuel cell through a hydrogen supply path. The supercharger supplies air from the outside air to the fuel cell. Through the pipe line, an exhaust from the fuel cell is discharged to the outside. The in-wheel motor serves as a driving source of the fuel cell two-wheel vehicle, and the motor driver drives the in-wheel motor. In an air system, a route and an outlet of the pipe line are arranged to be directed toward the motor driver. Thus, a heat sink is exposed to the discharged air having passed through the fuel cell, and thereby the motor driver is cooled.
