High pressure common rail diesel injection system can be achieved for fuel injection pressure and injection pulse width, injection timing, such as flexible control, electronic control diesel engine is to meet the Ⅳ and above the fuel system of choice for emissions standards, at the same time, also has significant high pressure common rail diesel engine fuel economy and robust performance.
Based on the high pressure common rail diesel engine ECU RapidECU rapid development solution, users can be done in a few weeks of high pressure common rail diesel engine ECU prototype prototype development, realize the engine starting, idling, deceleration, such as basic conditions, development samples in a few months to complete the batch products, implementation of small and medium-sized batch loading, for the high pressure common rail diesel engine ECU mass industrialization to lay a good foundation.
The electric control system of high pressure common rail diesel engine
Basic functions:
• Engine starting and idle control
• Multiple injection control, complex spray oil waveform control
• Rail pressure control, smoke restriction function
• Torque control, transition condition adaptive control
• Cooling fan control, preheating control
• Engine speed limit function, exhaust protection
• Variable section turbocharger control
In the face of the world within the scope of the rise in oil prices and the increasingly stringent emission regulations, the major forms and research institutions are committed to research and development have a higher thermal efficiency, economy and low emissions of alternative fuel engine. Through research and analysis of alternative fuel engine technology and the latest trends in industrial development, combined with our company in the field of engine control technology resources advantage and development of experimental platform to provide customers with alternative fuel engine management system development turnkey engineering solutions, suitable for cars, ships, engineering machinery, energy, electric power industries.
