Abstract

The invention provides a cold wear and hot test device of an engine, and relates to a running-in device of the engine. The cold wear and hot test device solves the problems that the existing mode of hoisting the engine on a vehicle to be subjected to running-in is long in running-in time, and overhaul and detachment are not convenient in the running-in process. The cold wear and hot test device comprises a cold wear part and a hot test part. The cold wear part comprises a gearbox a transmission shaft and the engine which are sequentially arranged on a working table, and a motor and a belt transmission device which drive the gearbox to work. An output shaft of the engine is fixedly connected with the gearbox through a transmission shaft. A support is arranged between the output shaft of the engine and the working table. The hot test part comprises an automobile gas filling dial, a pressure reducer, a heat exchanger, an injection valve, an air filter and a throttle valve which are sequentially connected through a gas pipe. The throttle valve is connected with a cylinder of the engine. The cold wear and hot test device is used for running-in of the engine.

Description

technical field [0001] The invention relates to an engine running-in device, in particular to an engine cold grinding and heat testing device. Background technique [0002] The engine is the heart of the car and the main factor affecting the power of the car. Gas vehicles will wear and tear during use, the mechanical aging phenomenon is serious, and engine failures occur frequently, which seriously affects the vehicle's intact rate and outage rate. Usually overhaul is required, but the overhauled engine cannot be put into work directly, and needs to be hoisted to the vehicle for running-in. This has a huge impact on enterprises that need vehicles for transportation. For example, using gas vehicles to transport coal, aging Due to the influence of many factors such as the working environment under the pit, road problems, heavy load and heavy workload, the life of the car's engine is greatly shortened. The average overhaul is once a year, and it takes at least six days for ov...
