Development of an Ammonia Reduction Aftertreatment Systems for Stoichiometric Natural Gas Engines

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Research and Development Trends in Combustion and Aftertreatment Systems for Next-Generation HSDI Diesel Engines

Recently, the performance and exhaust emissions of high-speed direct injection (HSDI) diesel engines for passenger cars have been rapidly improved. In these engines, the power and torque densities have reached 50-60 kW/l and 160-170 Nm/l, respectively. In addition, the noise, vibration and harshness (NVH) and exhaust emissions have been decreasing toward a level that is comparable to that of ga...

Simulation of Dual Fuel Combustion of Direct Injection Engine with Variable Natural Gas Premixed Ratio

Nowadays, the major challenge of diesel engines development is simultaneous nitrogen oxides and soot emissions reduction without the thermal efficiency drop. Hence, different combustion concepts should be investigated to reach optimum emission and performance conditions in diesel engines without expensive aftertreatment systems. This paper presents the results of a study on a dual fuel (DF) eng...

Application of Natural Gas for Internal Combustion Engines

Coordinated Planning and Scheduling of Electricity and Natural Gas Systems

In this paper we propose a model for coordinated planning of power and natural gas systems, as a part of electricity supply chain. This model takes into account costs and constraints of both systems, and with hiring simplifications and linearization methods transforms initially nonlinear formulation to a mixed integer linear programming (MILP) problem. Natural gas would be assumed steady state,...
