摘要:
An engine exhaust cleaning device is configured to prevent the temperature of a particulate matter filter (DPF) from rising sharply due to a reduction in the exhaust gas flow rate when a vehicle decelerates and shifts into idling operation during regeneration of the particulate matter filter. During regeneration of the particulate matter filter, the fuel cut (F/C) recovery engine speed used during deceleration is increased and the engine idling speed is increased for a prescribed amount of time when the engine idles.

An exhaust passage (2) of a diesel engine (1) is provided with a filter (41) for trapping particulate matter. Regeneration of the filter (41) is divided into first to third phases. In the first phase the filter temperature is raised to the combustion temperature of the particulate matter in a short period of time through control of the exhaust gas temperature. In the second phase, the oxygen concentration of the exhaust gas is held at a predetermined low level while the filter temperature is maintained so as to prevent excessive combustion of particulate matter. In the third phase, wherein the amount of trapped particulate matter has been reduced, the oxygen concentration of the exhaust gas is held at a predetermined high level while the filter temperature is maintained so as to complete the combustion of the trapped particulate matter.

摘要:
The present invention relates to an article having a silver layer and a resin composition for a coating material for silver which is used in reflective mirrors of photocopy machines and reflective members for indoor and outdoor lighting appliances, automobile headlights and the like. The article having a silver layer of the present invention has a first cured coating layer (A) comprising a resin having anti-corrosion properties for silver, and adhesiveness for both the substrate and silver or metal comprising mainly silver formed between the substrate and the silver layer (B); and, formed on the silver layer (B), a second cured coating layer (C) comprising a resin selected from the group consisting of a silicone acrylic resin (cl), a silicone alkyd resin (c2), and a multi-functional silicon cross-linked resin (c3) having a main chain formed by siloxane bonds. This type of article having a silver layer is superior in anti-discoloration (anti-corrosion) properties of the silver layer (B). In addition, since the resin composition for coating materials for silver of the present invention contains a multi-functional silicone cross-linked resin (c3) having a main chain formed by siloxane bends, it is superior in heat resistance, there is no yellowing of the coating thereof even when exposed to temperatures around 200° C. and it gives superior anti-discoloration (anti-corrosion) properties to silver.
