NOx Emission and Fuel Economy of the Honda CVCC Engine 741158

In this paper, the experimental results concerning the effect of the geometrical and operating factors of the CVCC engine on NOx emission, taking into consideration the fuel economy, are described with respect to a specific engine configuration, and they are compared with the results calculated by means of the mixture formation model. Furthermore the relationship between the NOx emission level and specific fuel consumption has been explained, and then it has been shown that the controlled combustion obtained with the CVCC engine is very effective for eliminating fuel economy penalty and reducing emissions.
