Definitions
- the present invention relates to a wheel loader.
- a diesel engine is generally used as a wheel loader engine.
- the hydraulic excavator described in Patent Document 1 includes a selective catalyst reduction device, an injection device, a reducing agent tank, a reducing agent pump, and a reducing agent pipe.
- the reducing agent pump sends the reducing agent stored in the reducing agent tank to the injection device via the reducing agent pipe, and the injection device injects the reducing agent into the exhaust gas upstream of the selective catalyst reduction device.
- the nitrogen oxides of the exhaust gas discharged from the engine are reduced to nitrogen.
- the reducing agent pipe Since the injection device is generally arranged in the engine compartment, the reducing agent pipe must pass through the engine compartment. However, the reducing agent flowing in the reducing agent pipe is heated by radiant heat from the selective catalyst reduction device housed in the engine compartment. Urea water generally used as a reducing agent changes to ammonia when heated. Since ammonia is strongly alkaline, there is a problem that durability of a reducing agent pipe, an injection device, a reducing agent pump, a reducing agent tank, or the like is lowered.
- An object of the present invention is to prevent the reducing agent pipe from being heated.
- a wheel loader includes an engine, a selective catalyst reduction device, an injection device, an engine room, a vehicle body cover, a partition plate, a reducing agent tank, a reducing agent pump, and a reducing agent pipe.
- the selective catalyst reduction device processes exhaust gas from the engine.
- the injection device injects the reducing agent into the exhaust gas sent from the engine to the selective catalyst reduction device.
- the engine chamber houses an engine, a selective catalyst reduction device, and an injection device.
- the vehicle body cover defines an engine compartment.
- the partition plate includes a first partition portion disposed between the selective catalyst reduction device and the vehicle body cover.
- the reducing agent tank is disposed outside the engine compartment and stores the reducing agent.
- the reducing agent pump supplies the reducing agent from the reducing agent tank to the injection device.
- the reducing agent pipe connects the reducing agent pump and the injection device, and extends between the vehicle body cover and the partition plate in the engine compartment.
- the first partition portion of the partition plate is disposed between the vehicle body cover and the selective catalyst reduction device, and the reducing agent pipe extends between the first partition portion and the vehicle body cover. Therefore, it is possible to prevent the radiant heat from the selective catalyst reduction device from being blocked by the first partition portion and heating the reducing agent pipe. As a result, when the reducing agent flowing in the reducing agent pipe is urea water, the urea water can be prevented from changing to ammonia.
- the wheel loader further includes a support member.
- the support member supports the reducing agent pipe so as to extend between the vehicle body cover and the partition plate in a state in which the reducing agent pipe is spaced a predetermined distance from the partition plate.
- the reducing agent pipe can be prevented from coming into contact with the partition plate by supporting the reducing agent pipe with the support member. Since the partition plate is heated by the radiant heat from the selective catalyst reduction device, heat conduction from the partition plate to the reducing agent pipe can be prevented by preventing the reducing agent pipe from coming into contact with the partition plate.
- the vehicle body cover includes a bulging portion that bulges outward including the pipe inlet.
- the reducing agent pipe is introduced into the engine room from the pipe inlet.
- the reducing agent pipe is introduced into the engine room from the pipe introduction port of the bulging portion. Since the bulging portion bulges outward, the reducing agent pipe can be introduced into the engine compartment without abrupt bending. Further, if the reducing agent pipe is extended along the bulging portion, the bulging portion bulges outward, so that the reducing agent piping can be arranged at a position further away from the selective catalytic reduction device.
- the partition plate further includes a second partition portion disposed between the injection device and the selective catalyst reduction device. According to this configuration, radiant heat from the selective catalyst reduction device to the injection device can be blocked by the second partition.
- the wheel loader further includes a cab, a hydraulic oil tank, and a relay member.
- the cab is provided with a driver's seat inside.
- the hydraulic oil tank is disposed between the cab and the engine compartment.
- the relay member is disposed on the side of the hydraulic oil tank.
- the reducing agent pipe has a first pipe that connects the relay member and the injection device, and a second pipe that connects the relay member and the reducing agent pump.
- the reducing agent pipe is constituted by two pipes of the first pipe and the second pipe, the length of the pipe to be handled can be shortened and the replacement work can be facilitated.
- the pipes are not exchanged in vain by replacing them at appropriate times.
- the reducing agent pipe has a heating wire for heating the reducing agent flowing inside, and the heating wire of the first piping and the heating wire of the second piping are controlled independently of each other. According to this configuration, only the necessary pipes of the first pipe or the second pipe can be heated with the heating wire, so that power saving can be achieved. In general, since the second pipe connecting the relay member and the reducing agent pump is exposed to the outside air, there are more opportunities to heat the second pipe with a heating wire than the first pipe.
- the reducing agent is urea water.
- urea water is injected into the exhaust gas at a high temperature, the urea water is hydrolyzed to obtain ammonia. This ammonia chemically reacts with nitrogen oxides, and the nitrogen oxides are reduced to nitrogen and water.
- the reducing agent pipe can be prevented from being heated.
