Engine Control Strategy

EMS is an engine management system integrated with fuel injection, ignition angle and emission control. It uses a variety of sensors
to convert the engine intake air volume, cooling water temperature, engine speed and other conditions into electrical signals, which
are managed by ECU. Through the sensor information, the fuel supply, ignition advance angle and idle air flow can be calculated
accurately, which can greatly improve the engine performance Motivational performance.

Engine Control Strategy
—— Electronic Control System Of High Pressure Common-Rail Diesel Engine
High pressure common rail diesel injection system can realize the flexible control of fuel injection pressure, injection pulse width and injection timing. It is the preferred fuel system for electronically controlled diesel engines to meet the National IV and above emission standards. At the same time, the high pressure common-rail diesel engine also has significant fuel economy and strong power performance.

Based on RapidECU rapid development solution for high pressure common rail diesel engine ECU, users can complete the development of high pressure common-rail diesel engine ECU prototype within a few weeks, realize the basic working conditions of engine starting, idling, acceleration and deceleration, complete the development of mass product samples within a few months, realize the small and medium-sized batch loading, and lay a good foundation for the mass industrialization of high pressure common-rail diesel engine ECU.
 


Composition of electronic control system for high pressure common-rail diesel engine

Basic Functions:
•  Engine start and idle control
•  Multi injection control, Complex injection waveform control
•  Rail pressure control, Smoke limit function
•  Torque control, Adaptive control of transition conditions
•  Cooling fan control, Preheating control
•  Engine speed limit function, Exhaust temperature protection
•  Variable section turbocharger control
 
—— Alternative Fuel Engine Management System
In the face of the rising oil price and more and more stringent emission regulations around the world, major engine plants and research institutions are committed to the development and research of alternative fuel engines with higher thermal efficiency, economy and low emissions.

Through the research and analysis of the latest trend of alternative fuel engine technology and industrial development, combined with our company's technical advantages in the field of engine control and development of test platform resources, we provide customers with alternative fuel engine management system development turnkey engineering solutions, which are suitable for automobile, ship, engineering machinery, energy and power industry users.

Composition of typical application system:



 
Mainly for the following engine types:
•  Natural gas - diesel hybrid fuel engine
•  Methanol \ ethanol-gasoline hybrid fuel engine
•  LNG\CNG\LPG engine
