[0002] The tractor exhaust tail pipe is an important component of the engine exhaust system, which can guide and control the temperature of the high-temperature gas discharged by the engine. Under extreme working conditions, the exhaust temperature of the engine can reach 800-1000℃, and with corresponding protective measures, the temperature can reach as high as 200℃; at the same time, the tractor operating conditions are generally farmland and orchards, and the working environment is relatively harsh, with a lot of combustibles such as weeds and wood chips. The exhaust tail pipe is generally arranged on the side of the rear end of the engine body. Most of the engine fans are suction fans. The fan airflow can easily blow up combustibles and scatter them near the high-temperature components such as the exhaust tail pipe and cause fires. In severe cases, it will cause the vehicle to spontaneously combust, causing significant economic and property losses.
