Combustion stability, engine efficiency and emissions in a multi-cylinder spark-ignition internal combustion engines can be improved through the advanced control optimization of individual cylinder operation. In this work, experimental numerical analyses were carried out on twin-cylinder turbocharged port fuel injection (PFI) to evaluate influence cylinder-by-cylinder variation performance poll...

The concept of control Lyapunov function has proven a useful tool for designing robust control laws for nonlinear systems. Recently, this concept has been extended to time-delay systems in the form of Control Lyapunov Razumikhin functions and Control Lyapunov Krasovsky functionals (CLKF). Universal formulas, such as Sontag's formula and domination redesign formula, apply to CLKF's and achieve r...

Due to environmental changes across the global, there is urgent need take care of pollutions. 15–20% air pollution caused by automobiles, reason behind incomplete combustion, lack oxygen in fuel and etc. There are so many methods developed make good combustion inside cylinder adding additives, using biodiesels, changing injection timing pressures. Present researchers Nano additives harmful plan...

Dilution of the intake air of the SI engine with the inert gases is one of the emission control techniques like exhaust gas recirculation, water injection into combustion chamber and cyclic variability, without scarifying power output and/or thermal efficiency (TE). This paper investigates the effects of using argon (Ar) gas to mitigate the spark ignition engine intake air to enhance the perfor...

Moderate or intense low-oxygen dilution (MILD) combustion is a novel technique that can simultaneously improve thermal efficiency and reduce emissions. This paper focuses on the differences in statistical behaviours of surface density function (SDF = magnitude reaction progress variable gradient) between conventional premixed flames exhaust gas recirculation (EGR) type homogeneous-mixture under...

Internal combustion engines working at cold conditions lead to the production of excessive pollutant emissions levels. The use exhaust gas recirculation could be necessary reduce nitrogen oxides emissions, even these conditions. This paper evaluates impact using high-pressure strategy while diesel particulate filter is under active regeneration mode on a Euro 6 turbocharged engine running low a...
