Self-adapting cold grinding and hot testing apparatus for car engine

Abstract

The invention relates to a cold grinding and hot testing device for an engine of a self-adaptive type automobile and belongs to automobile engine grinding and detection technology. The device mainly comprises a test bench (A) for an engine cold grinding and hot testing system, an engine hoisting system (B), a cooling system (C), a control chamber (E) and a smoke exhaust system (F). The device is characterized in that the test bench (A) for the engine cold grinding and hot testing system is fixed on a test bench groundsill (35); the engine hoisting system (B) is fixed on a house groundsill; a crossbeam and a house girder (D) are fixed by a U-shaped bolt; the cooling system (C) is fixed on the underground part of a house and forms an integrated structure with the house groundsill; the control chamber (E) is fixed on one corner of the house; and the smoke exhaust system (F) is fixed on the underground part of the house and forms an integrated structure with the house groundsill. The device realizes the function of completing cold grinding and hot grinding on the same bench and can directly carry out power testing on the ground engine.

Description

technical field [0001] The invention relates to an adaptive cold-grinding and hot-testing device for an automobile engine, which belongs to the automobile engine running-in and detection technology. Background technique [0002] The engine is the heart of the car and the main factor affecting the power of the car. In order to improve the power and economy of the overhauled engine, prolong the service life of the engine, and check whether the performance of the engine after repair reaches the specified standard, it is necessary to carry out a cold grinding and hot test on the engine after the overhaul. [0003] The purpose of running-in is to improve the surface quality of the matching parts, to establish the matching surface suitable for the working conditions as soon as possible with the minimum amount of wear and the shortest running-in time, to prevent destructive wear and prolong the service life of the engine. During the running-in process, it can also check and elimin...

AI Technical Summary

Problems solved by technology

However, these devices are expensive, maintenance costs and training costs are also very high, and it is difficult to be fully compatible with existing product measurement and control systems (such as water temperature, fuel pressure control systems, etc.) Give full play to the effectiveness and utilization of the system, resulting in waste of production and technology

After decades of development, domestic engine bench measurement and control systems have also improved by leaps and bounds. Although some manufacturers have relatively mature technologies, these dynamometers have a common shortcoming: lack of dynamic monitoring of electronically controlled engine PCM (or ECU) work Status capabilities and networked data management functions cannot meet the needs of mass production
