The pressure drop across DPFs directly affects the exhaust back-pressure and fuel economy of
compression ignition engines. Pressure drop is related to the soot trapped inside the DPF, increasing
exhaust back-pressure as ...
Nowadays, EGR systems are being incorporated in the research focused on spark-ignition direct-injection engines
as a solution to the problems presented by them; i.e. knock risk and high combustion temperature which produces ...

A study of soot measurement deviation using a diffusion charger sensor with three dilution ratios was conducted in order to obtain an optimum setting that can be used to obtain accurate measurements in terms of soot mass ...
In this study, an experimental investigation of particle size distribution emission over performance of transient
conditions in a high speed diesel engine fuelled with diesel, biodiesel and Fischer Tropsch fuels have been ...
