摘要： The present invention relates to a structure of a liquid reducing agent injection nozzle in an exhaust emission purifying system arranged to inject and supply a liquid reducing agent into an exhaust flow passage so as to reduce and purify NOx in exhaust gas. A nozzle tip end portion (12a, 20a, 30a, 40a) of the liquid reducing agent injection nozzle (12, 20, 30, 40) which protrudes from a wall surface of an exhaust flow passage into the passage, is bent obliquely with respect to an exhaust flow direction, or nozzle holes (21, 31,41) of the nozzle tip end portion are formed so as to tilt in the exhaust flow direction with respect to a radial direction perpendicular to a center axis of the nozzle tip end portion or are unevenly distributed in the circumferential direction of the nozzle tip end portion.

摘要： Reliable brake switch failure diagnosis is enabled with a simple structure. When it is judged that brake switches (6a, 6b) are both not in on state and not in off state (S110, S112), first and second judgment counters perform counting (S114, S120). When it is judged that the brake switches (6a, 6b) are both in on state, the count of the first judgment counter is reset to zero (S132). When it is judged that the brake switches (6a, 6b) are both in off state, the count of the second judgment counter is reset to zero (S136). This operation is cyclically repeated. When the count of one of the first and second judgment counters exceeds predetermined corresponding value α or β (S118, S214), one of the brake switches (6a, 6b) is judged as failed. Thus, a failure that one of the brake switches (6a, 6b) stays normally on or off can be detected.

摘要： An exhaust gas purification device is provided that is capable of diffusing and introducing a reducing agent into a NO x catalyst arranged in a downstream side exhaust gas passage. The exhaust gas purification device is compact and has an exhaust gas passage that returns back in the middle thereof. A housing of the exhaust gas purification device includes a main body in which an upstream side exhaust gas passage and the downstream side exhaust gas passage are housed, and a cap which is attached to a first surface of the main body that is provided with an outlet side opening of the upstream side exhaust gas passage and an inlet side opening of the downstream side exhaust gas passage. The return portion is formed by a space surrounded by the main body and the cap. At least one of the first surface of the main body and a second surface in the cap which faces the first surface is provided with a guide portion, for guiding an exhaust gas flow, which is arranged in a direction intersecting with the first surface and the second surface, and a reducing agent diffusion portion, for facilitating mixing of the reducing agent with the exhaust gas, which is arranged in the middle of the flow of the exhaust gas guided by the guide portion.

摘要： An automatic speed-change control device comprises a speed change map for detecting an accel operation quantity provided by the operator stepping on the accel pedal and detecting the engine rpm depending on the detected accel operation quantity, the speed change being regulated by the accel operation quantity and engine rpm, wherein the speed changer is automatically shifted up or down for start control on the basis of the speed change map, the arrangement being such that the point at which the speed change map is switched by the operator stepping on the accel pedal is made learnable, preventing occurrence of unnecessary shift-down or delay in shift-up, ensuring efficient travel.
