进入二十一世纪，随着电子技术的突飞猛进电子技术和汽车产业都有了前所未有 的发展。两者的有机结合，有力地推动了汽车工业的发展。汽车采用微电子控制系统 等智能化部件后，其性能得到了显著的改善和提高。然而，这些高科技装置使我们在得 到方便的同时，却给汽车维修行业带来了严峻的考验，传统的汽车维修技术和汽车维修 工艺已经远远不能适应现代的汽车工业，现代汽车工业的维修技术已经上升到和汽车设 计同等重要的地位。      

    随着现代科学技术的快速发展推动了发动机试验的进步。冷磨合技术是近年来发展起 来的新技术。国外汽车制造企业已发展冷磨合技术来代替热磨合架，而国内还是以热磨合架为主要 检测方式。 按照负载状态，热磨合架有加载和空载两种方式。目前，我国国内大部分柴油机采取加 载热磨合试验。我国汽油机的热磨合大部分采用空载的形式，而国外开始使用加载热磨合架验设备。

 

 

 Abstract

Into the twenty-first century, with the electronic technology by leaps and bounds electronic technology and the automotive industry has an unprecedented development. The combination of the two, a strong impetus to the development of the automotive industry. Automotive microelectronics control system and other intelligent components, its performance has been significantly improved and improved. However, these high-tech devices so that we are at the same time, but to the car repair industry has brought a severe test, the traditional vehicle maintenance technology and vehicle maintenance technology has been far from being able to adapt to the modern automotive industry, modern automotive industry maintenance Technology has risen to the same important position as car design.

With the rapid development of modern science and technology to promote the progress of the engine test. Cold running technology is a new technology developed in recent years. Foreign automobile manufacturing enterprises have developed cold running technology to replace the hot mill, and the domestic or hot mill with the main detection method. In accordance with the load state, the hot mill has two ways of loading and unloading. At present, most of China's domestic diesel engine to take the hot running test. China's gasoline engine run-in most of the use of no-load form, and foreign began to use the loading of hot running test equipment.

The design of the engine hot mill frame, mainly for automotive engine assembly assembly, decomposition and hot run.

 

Keywords: engine; assembly; hot mill stand
