In this paper, a multivariable control strategy based on a parameterized Nonlinear Model Predictive Control (NMPC) approach is proposed for a Diesel engine air path. The aim is to control the level of pollutant emissions by coordinating the Exhaust Gas Recirculation (EGR) and the Variable Geometry Turbocharger (VGT) valves simultaneously. The main feature of the proposed controller lies in its ...

Contact cooling using thermopressor technologies is a promising direction for the development of energy-efficient technologies. This technology based on implementation thermo-gas-dynamic compression effect in special contact heat exchangers that consists increasing pressure while decreasing temperature during evaporation finely dispersed liquid injected into gas flow moving at speed close to so...

Water cooled turbochargers used in gasoline engines present a difficulty studies due to heat transfers both the turbine and compressor. Data available for users is usually measured stable operating conditions with high temperature gradients on side which affects compressor whole turbocharger. The between different elements are not quantified. Heat transfer models necessary quantify amount of ex...

The use of supercharged diesel engines improves the combustion process, increases efficiency engine and overall its operation. As a concomitant beneficial effect, there is an increase in environmental performance engine. All above factors are particularly relevant for solving problem converting so-called "atmospheric" into turbocharged engines, objects conversion can be fleet old models that ha...

Water injection strategy is considered a promising technique to improve the performance of boosted engine and reduce NOx emission via latent heat water vaporization. Numerous research on has been conducted in-cylinder intake port injection. However, focusing spark ignition (SI) exhaust system still lacking. This study proposed pre-turbocharger turbine (PTWI) concept inlet temperature. was done ...
