Summary: In this paper, the modern car engine electronic control system with the development of purpose, significance and the status quo; focuses on the modern car engine electronic control systems (including time control diesel EFI, Common Rail EFI, in the turbocharged Cold, EGR) of the new technology at the same time pointed out the new Common Rail EFI technology is the future of modern diesel engine car the inevitable trend of development.
Key words: Common Rail Diesel Engine Electronic Control System-EFI new technology

1. Diesel Engine Electronic Control System Development

Hyundai Motor gasoline and electrical control technology development background, unavoidable in the face of local and global environmental and energy issues, the modern diesel engine vehicles to use and the development of electronic control systems, in order to maintain the sustainable development of diesel engine vehicles, give full play to the inherent advantages of diesel engine (low fuel consumption and low CO2 emissions). Maintain excellence in diesel engine fuel economy at the same time, in order to meet increasingly stringent emissions regulations, in addition to reducing oil consumption, optimized turbocharger technology and the use of advanced exhaust after-treatment system, the main engine of the need to be further improved combustion process. The fuel injection system performance impact of diesel engine combustion process is the key, using micro-electromechanical control technology to improve the combustion process of many new technologies, although some new technology and electronic control technology did not directly linked, but to improve the overall performance, Electronic technology and still have an indirect link.
