Auxiliary tool of engine hot test connection process exhaust device

Abstract

The invention relates to an auxiliary tool for connecting an engine with a process exhaust device in a hot test, which comprises a rectangular shaping plate, a protective plate and two handle components, the front side of the rectangular shaping plate is in contact with the process exhaust device, the upper side of the protective plate is vertically connected with the rear side of the rectangular shaping plate, and the process exhaust device is attached to an exhaust surface of an engine cylinder cover; the protection plate is connected with the process exhaust device through a long bolt; limiting components are arranged on the left side and the right side of the protection plate respectively. One ends of the two pairs of limiting components respectively penetrate through the process exhaust device and are connected with the exhaust surface of the engine cylinder cover; the structure of the process exhaust device is the same as that of the exhaust manifold, the process exhaust device is of a cavity structure, the upper portion of the process exhaust device is provided with a combination face, the lower portion of the process exhaust device is provided with an exhaust pipe, and the combination face is provided with exhaust holes and attached to the exhaust face of the engine cylinder cover. The air exhaust accessory can solve the problem that a naturally aspirated engine hot test original air exhaust accessory is too large in size and inconvenient to install, can also solve the problem that the assembling space is limited, and is convenient and fast to operate, safe and reliable.

Description

technical field [0001] The invention relates to an engine thermal test, in particular to an auxiliary tool for an exhaust device of an engine thermal test connection process. In particular, it is an auxiliary tool for hot test connection process exhaust pipes of naturally aspirated engines. Background technique [0002] Before the engine is sent to the vehicle assembly workshop, the hot test bench is used as the terminal inspection station of the engine, and various vehicle accessories need to be assembled for inspection. If the original accessories of the whole vehicle are used for reconstruction, the assembling and storage of the tooling will require a large area. If the derivative models have many states, it is necessary to reserve a very large hot test room to switch tooling, which wastes the process layout. The exhaust pipe of the engine is also an accessory of the whole vehicle. Some naturally aspirated models are designed with the exhaust pipe and the three-way cata...
