Founded in 1993, he has been working on the research and development of dynamic maintenance models for automobiles and engineering machinery, and is now spread throughout the country. Much of the effort has been made to develop and innovate on the basis of traditional maintenance, using high-tech technology tools, based on a governance-based, surveillance-backed approach, a service model that integrates car conservation with tail gas management and is integrated with the information age and fully meets the individualized needs of the owner. Over the years of conservation experience, a unique set of logical conservation theory systems centred on cylinder pressure, based on the functionality of the systems, organized by function, closely around the three elements of the engine. This dynamic, functional, logical thinking approach is function-oriented and analyses, processes and solves problems according to the logical linkages between the systems. The system-by-system roll-out of the traditional system-based organization-based thinking approach to drug-painted and arranged analysis, treatment and problem-solving has clear advantages, simplifying the process of analysis and treatment and improving the accuracy of analysis, judgement and treatment. It is a major advance in the way of thinking and a breakthrough in conservation and maintenance theories, especially in the way of judging problems。
