Abstract

The invention discloses a flow guide structure for improving local high temperature of an exhaust side of a longitudinal engine assembly. The structure comprises an engine assembly and a particulate trap assembly arranged at the exhaust side of the engine assembly, and further comprises a flow guide component arranged between the engine assembly and the particulate trap assembly, wherein the flow guide component comprises a flow guide plate main body and a mounting component, the flow guide plate main body is connected with the particulate trap assembly through the mounting component, the flow guide plate main body comprises a flow guide plate front section, a flow guide plate middle section and a flow guide plate rear section which are sequentially connected from front to back, and a heat source airflow flowing inlet is formed among the flow guide plate front section, the engine assembly and the particulate trap assembly. The structure solves the problem of local high temperature of the exhaust side of the longitudinal engine assembly, the structures of the engine assembly and the particulate trap assembly do not need to be changed, the cost is low, the change of the whole vehicle is small, and the transformation period is short.

Description

technical field [0001] The invention relates to an engine assembly, in particular to a flow guide structure for improving local high temperature at the exhaust side of a longitudinal engine assembly. Background technique [0002] With the increasing demand for pickup trucks in the automotive market, customers' requirements for pickup trucks are gradually increasing. From the past, it was only enough to meet the needs of pulling goods, to the current high-quality multi-purpose family car. With the improvement of the quality of pickup trucks, the requirements for the thermal management of the cabin are also more stringent, especially the thermal aging and thermal failure of the electrical components in the engine assembly compartment. Restricted by the layout of the vehicle's engine assembly cabin, the engine assembly of most pickup trucks is arranged vertically. When the exhaust side of the engine assembly is outside the fan wake (that is, away from the fan outlet area), it...
