Abstract
The invention discloses a particle catcher with a cooling function and a vehicle. The heat transfer on the surface of the end cone of the particle catcher can be effectively blocked, and the temperature of the air around the particle catcher is reduced.
Description
Technical Field
The invention relates to a vehicle engine, in particular to a particle catcher with a cooling function and a vehicle.
Background
The particle trap is used for trapping particles in engine exhaust gas, and then combusting the particles to generate carbon dioxide to be discharged into the atmosphere, so that emission pollution is reduced. Typically the particulate trap is mounted at the bottom of the vehicle remote from the engine and close to the muffler. However, with the stricter and stricter national emission regulations, the regeneration temperature of the particle catcher is often lower after the particle catcher is far away from the engine, which cannot meet the requirements of the emission regulations, and the trapped particles can be rapidly and thoroughly combusted only by installing the particle catcher on the engine and increasing the regeneration temperature of the particle catcher, thereby reducing the atmospheric pollution.
However, when the particulate trap is installed on an engine, the temperature of air around the particulate trap is also rapidly increased due to continuous combustion of particulate matter in the particulate trap, and the problem of thermal damage caused by the narrow engine compartment, slow heat dissipation, and numerous parts is also becoming more and more serious. Referring to fig. 1, particulate matters in engine exhaust gas are continuously combusted in a cylinder of the particulate trap, high-temperature gas passes through an end cone of the existing particulate trap 8 and then is subjected to heat transfer, so that the temperature of air around the end cone is rapidly increased, and high-temperature air around engine parts closest to the end cone, such as an oil filter 10, cannot be diffused in time, and the temperature of the engine parts is continuously higher and even exceeds the temperature resistance limit of the oil filter 10 by 120 ℃, so that the service life of the engine parts is greatly reduced, and the performance of the engine is affected.
In order to solve this problem, referring to fig. 1, the prior art approach is to weld a stainless steel heat shield 9 to the end cone of the existing particle catcher 8 for heat insulation. However, this measure can only block part of the heat of the end cone, and cannot reduce the temperature of the air around the end cone, and cannot completely solve the problem of heat damage of the components such as the oil filter 10.
