Nowadays optimization is increasing in experiments on the engine tests studies. In this study, the test fuel obtained by mixing isopropanol with n-heptane fuel under various engine conditions in HCCI mode was examined combustion, performance and emissions. The study was carried out both experimentally and statistically. Set as engine parameters, different engine speed, test fuel with isopropanol (IP20-IP40) and excess air ratio for experimental study. Engine speed is 800 rpm -1200 rpm, excess air ratio is 1.6 and 2.8, and isopropanol ratio in test fuel of 20% and 40%. From the experiment, investigations were made on effective torque, indicated mean effective pressure, indicated thermal efficiency, maximum pressure increase rate, start of combustion (SOC), combustion duration, COVIMEP, HC, CO and NOx. Before the experiments, experimental series were determined with Response Surface Method, Central Compound Design matrix. Experiments were carried out with the experimental series obtained and the data were analysed. Counter charts, ANOVA results and quartic models were obtained by entering the combustion, performance and output of the HCCI engine into the RSM interface. Then, the targeted response parameters were entered and optimization was made to determine the optimum input parameter. Response parameters under optimum operating conditions Effective Torque 11.438 Nm, IMEP 4.366 bar, MPRR 2.747 bar/°CA, COVIMEP 4.364%, CA10 2.315 °CA, CA50 7 °CA, CA10-CA90 36.245 °CA, UHCs 324.562 ppm, CO 0.0118% and NOx 2.549 ppm were determined.

“…It significantly affects the thermodynamic properties of the overall combustion process and therefore has to be carefully controlled in order to yield a desired engine behavior [27]. In particular, the ignition timing substantially changes the pressure and temperature characteristics inside the cylinder which, in turn, leads to a high impact on basic engine properties such as fuel consumption, mechanical efficiency, and the formation of pollutants [27][28][29][30]. It is generally specified by defining the spark event to occur at a specific crank angle ζ during the engine cycle and is expressed in relation to the top dead center (TDC) of the engine.…”

Reduction of Cold-Start Emissions for a Micro Combined Heat and Power Plant

et al. 2020

Decentralized power generation by combined heat and power plants becomes increasingly popular as a measure to advance the energy transition. In this context, a substantial advantage of small combined heat and power plants is based on the relatively low pollutant emissions. However, a large proportion of the pollutant emissions is produced during a cold-start. This fact is not reflected in governmental and institutional emission guidelines, as these strongly focus on the emission levels under steady-state conditions. This study analyzes the spark advance, the reference air/fuel ratio and an electrically heated catalyst in terms of their potential to reduce the cold-start emissions of a micro combined heat and power plant which uses a natural gas fueled reciprocating internal combustion engine as prime mover and a three-way catalytic converter as aftertreatment system. Based on these measures, control approaches were developed that account for the specific operating conditions of the class of small combined heat and power plants, e.g., full-load operation and flexible, demand-driven runtimes. The experimental data demonstrates that even solutions with marginal adaptation/integration effort can reduce cold-start emissions to a great extent.

Electrical turbocharger assist is one of the most critical technologies in improving fuel efficiency of conventional powertrain vehicles. However, strong challenges lie in high efficient operations of the device due to its complexity. In this paper, an integrated framework on characterization, control, and testing of the electrical turbocharger assist is proposed. Starting from a physical characterization of the engine, the controllability and the impact of the electrical turbocharger assist on fuel economy and exhaust emissions are both analyzed. A multivariable robust controller is designed to regulate the dynamics of the electrified turbocharged engine in a systematic approach. To minimize the fuel consumption in real time, a supervisory level controller is designed to update the setpoints of key controlled variables in an optimal way. Furthermore, a cutting-edge experimental platform based on a heavy-duty diesel engine is built. The proposed framework has been evaluated in simulations, physical simulations, and experiments. Results are presented for the developed system and the proposed framework that demonstrate excellent tracking performance, high robustness, and the potential for improvements in fuel efficiency. Index Terms-Electrical turbocharger assist (ETA), multivariable control, real-time energy management, system characterization, testing framework design. NOMENCLATURE GHG Greenhouse gas. EM Electrical machine. ETA Electrical turbocharger assist. TDE Turbocharged diesel engine. ETDE Electrified turbocharged diesel engine.
