CFD Investigation into Diesel PCCI Combustion with Optimized Fuel Injection
A multi-pulse injection strategy for premixed charge compression ignition (PCCI) combustion was investigated in a four-valve, direct-injection diesel engine by a computational fluid dynamics (CFD) simulation using KIVA-3V code coupled with detailed chemistry. The effects of fuel splitting proportion, injection timing, spray angles, and injection velocity were examined. The mixing process and fo...
متن کاملModeling and Control of Combustion Instability Using Fuel Injection
Active control using periodic fuel injection has the potential of suppressing combustion instability without radically changing the engine design or sacrificing performance. In this paper, we carry out a study of optimal model-based control of combustion instability using fuel injection. The model developed is physically based and includes the acoustics, the heat-release dynamics, their couplin...
متن کاملCFD Modeling of PROX Microreactor for Fuel Processing
In order to investigate a PROX microreactor performance, two-dimensional modeling of the reacting flow between two parallel plates is performed through a finite volume method using an improved SIMPLE algorithm. A three-step surface kinetics including hydrogen oxidation, carbon monoxide oxidation and water-gas shift reaction is applied for a Pt-Fe/γ-Al2O3 catalyst and operating temperatures of a...
متن کاملProcess modeling for future technologies
Process modeling is an integral portion of technology computer-aided design (TCAD) and can be used to predict device structures and doping. Truly predictive process modeling has proven to be an elusive goal, because the controlling physics is complicated and difficult to investigate experimentally. The current state of process modeling is reviewed, and current and future challenges are discusse...
متن کاملEngine Fuel Injection Control using Fuzzy Logic
This paper describes a cost-effective fuzzy control system applied to a small spark-ignition internal-combustion engine to achieve regulation of the fuel injection system. The system determines the amount of fuel required from a fuzzy algorithm that uses the engine speed and manifold air pressure as input values. The parameters of the fuzzy control paradigm were a collection of rules and fuzzy-...
