Definitions
- the present invention relates to an engine device mounted on a work machine such as a construction engineering machine, an agricultural machine, and an engine generator.
- the electrical wiring connector for the detection member for the exhaust gas purification device is disposed on the opposite side of the cooling fan in a plan view of the outer peripheral portion of the exhaust gas purification device,
- the electrical wiring connector can be positioned at a height that is substantially the same as or lower than the upper end of the exhaust gas purification device, and the electrical wiring connector with respect to the overall engine height including the exhaust gas purification device. This can reduce or eliminate the influence of the arrangement. Therefore, it is effective to keep the overall height as low as possible in the engine assembled with the exhaust gas purification device, and this also contributes to the downsizing of the engine.
- the bracket bodies are made of different materials, one is a cast iron bracket body, the other is a sheet metal bracket body, and the cast iron bracket body is fastened to the cylinder head of the engine. Therefore, by the fastening, it is possible to set the mounting reference position of the exhaust gas purification device with respect to the engine with high accuracy, and even if the exhaust gas purification device is heavier than a muffler that is a post-processing device, It can be properly mounted at a predetermined position.
- a fuel pipe for supplying fuel to the injector and a control harness are arranged close to each other outside the engine having an injector in the cylinder head, and the control harness is attached. Since the harness support is disposed on the cylinder head so as to straddle the fuel pipe, the cylinder, which is the high-temperature part of the engine, is mounted by fixing the control harness on the harness support. The control harness can be disposed away from the head, and contact between the fuel pipe and the control harness can be avoided. Therefore, deterioration of the control harness due to high temperature (heat) can be suppressed, and charging of the fuel pipe can also be prevented. Further, the presence of the harness support body makes it easy to grasp the wiring path of the control harness at the time of assembly, and helps to improve the assembly workability of the control harness.
- an engine 1 as a prime mover mounted on a work machine such as a construction civil machine or an agricultural machine has a continuously regenerative exhaust gas purification device 2 (DPF).
- the exhaust gas purification device 2 removes particulate matter (PM) in the exhaust gas discharged from the engine 1 and reduces carbon monoxide (CO) and hydrocarbons (HC) in the exhaust gas.
- a sensor fastening portion 46 with a through hole is formed on the intermediate clamping flange 45 of the purification casing 38 on the opposite side (the head cover 8 side) of the outer periphery of the purification casing 38 to the cooling fan 9.
- the exhaust pressure sensor 44 integrally provided with the electrical wiring connector 44 a is bolted to the sensor fastening portion 46 of the intermediate clamping flange 45. That is, an electrical wiring connector 44 a for the exhaust pressure sensor 44 for the exhaust gas purification device 2 is arranged on the opposite side of the outer periphery of the exhaust gas purification device 2 from the cooling fan 9.
- the exhaust pressure sensor 44 corresponds to a detection member.
- a reinforcing plate 74 is provided on the upper end side of the inlet side bracket body 71.
- the distal end portion (right end portion) of the reinforcing plate portion 74 of the inlet side bracket body 71 is connected to the upper end side of the outlet side bracket body 72. That is, a single mounting base 70 is configured by connecting the inlet side bracket body 71 and the outlet side bracket body 72 through the reinforcing plate portion 74.
- the receiving bracket 75 welded and fixed to the exhaust downstream side of the outer peripheral surface of the purification casing 38 is bolted to the base end portion (left end portion) of the reinforcing plate portion 74 fixed to the upper end side of the inlet side bracket body 71.
- the upper end side of the outlet side bracket body 72 is bolted to the intermediate clamping flange 45 of the purification casing 38.
- the exhaust-gas purification device 2 (purification casing 38) is supported on the cylinder head 5 of the engine 1 by the inlet-side bracket body 71 and the outlet-side bracket body 72 which are a single mounting base 70.
- the control harness 100 can be disposed away from the cylinder head 5 which is the high temperature part of the engine 1, and the Contact between the fuel pipes 102 and 103 and the control harness 100 can also be avoided.Therefore, deterioration of the control harness 100 due to high temperature (heat) can be suppressed, and charging of the fuel pipes 102 and 103 can be prevented. Further, the presence of the harness support 110 makes it easy to grasp the wiring path of the control harness 100 during assembly, and helps to improve the assembly workability of the control harness 100.
