Abstract
With increasingly strict federal and consumer standards for diesel engines, modifications to the fuel injection system are one of the most effective methods for engine improvement. The current research engine being studied is operated with traditional mechanical fuel injection, only capable of premixed charge compression ignition (PCCI) strategies with fixed injection timing and duration mechanically dependent on the speed and load of operation. Integration of an electronic common rail fuel injection system will enhance combustion control with reactivity controlled compression ignition (RCCI) strategies by providing custom injection commands depending on the engine operator.
The development of a diesel common rail fuel injection system consisted of configuring and testing hydraulic, electrical, and mechanical subcomponents. This research presents the process taken based on the verification and validation model, or V-model, of design and development for a powertrain system. In order to verify system operation and control, a test bench was designed to implement Hardware-In-the-Loop (HIL) testing by creating a virtual environment to test the entire systems operation depending on the signal inputs. HIL is crucial for time and cost reduction along with for safety of both the engine and engine operator during initial testing after system to engine integration.
Powertrain requirements were first identified in order to design a test bench to achieve adequate fuel flow and control at all engine operating conditions along with the flexibility of modifying the control modules for advanced combustion strategies. With the hardware configuration completed, the pressure regulator and fuel injector were then calibrated and investigated for the V-model process. System validation and verification was accomplished through HIL testing with a virtual engine, or plant, simulated through open source software programmed according to specifications of a real engine. This method provides validation of engine synchronous signal control along with providing the ability to coarsely tune the cruise control function for steady state operation at all speeds and loads.
