Homogeneous charge compression ignition technology has exhibited high potential to reduce fuel consumption and NOx emissions over normal spark-ignition engines significantly. Optimized kinetic process technology is implemented to realize homogeneous charge compression ignition combustion in a port fuel injection gasoline engine. The combustion and emission characteristics are investigated with ...
Current approaches to the analysis of internal combustion engines are no longer merely based on the first law of Thermodynamics and are conducted from the second law either. The evaluation of processes by the first law cannot provide a sophisticated insight into the issue. So, due to the necessity of having a detailed perspective of the losses in different thermodynamic processes, a useful m...
In spark ignition (SI) engines, the accurate control of air fuel ratio (AFR) in the stoichiometric value is required to reduce emission and fuel consumption. The wide operating range, the inherent nonlinearities and the modeling uncertainties of the engine system are the main difficulties arising in the design of AFR controller. In this paper, an optimization-based nonlinear control law is a...
