Investigations on the Potential of Miller Cycle for Performance Improvement of Gas Engine
Published In: GJRE Part: B: Automotive Engineering Volume: 16 Issue: 1
To further improve thermal efficiency, Miller Cycle was applied to a turbo-charged 338 kW gas engine. Different methods of Miller Cycle were analyzed, including three Early Intake- Valve Closing (EIVC) methods and three Late Intake-Valve Closing (LIVC) methods. After the relatively suitable methods were chosen, the combination of the Miller Cycle and higher compression ratio was extensiv...

Isolated Traffic Signal Control using Nash Bargaining Optimization
Published In: GJRE Part: B: Automotive Engineering Volume: 16 Issue: 1
This paper presents a novel isolated traffic signal control algorithm based on a gametheoretic optimization framework. The algorithm models a signalized intersection considering four phases, where each phase is modeled as a player in a game in which the players cooperate to reach a mutual agreement. The Nash bargaining solution is applied to obtain the optimal control strategy, consideri...

Development a Single Zone Heat Release Model
Published In: GJRE Part: B: Automotive Engineering Volume: 14 Issue: 4
Single zone heat release models can effectively be used to model diesel engine combustion process with acceptable degree of accuracy. These models are mainly depend on double Wiebe function which requires as many as six parameters in order to predict the heat release rate (HRR) accurately. However, Wiebe function does not look into the physical air fuel mixing process during the ignition...

Linear Damping Seat to Reduce Whiplash Injury in Rear-end Collision
Published In: GJRE Part: B: Automotive Engineering Volume: 14 Issue: 3
Neck injuries caused by rear end collisions have become a major problem in traffic safety over the last two decades. This situation calls for more research in the field. One area of interest is a damping seat slide to reduce neck injury. To reduce neck injury (Whiplash), based upon new biomechanical research, the motion between head and torso should be reduced. In case of a rear end impa...
