An experimental study was carried out to analyze the influence of different post-injection strategies on regulated and unregulated emissions from a heavy-duty compression ignition (CI) diesel engine. FTIR (Fourier transform infrared spectroscopy) used measure exhaust which include such as NOx, soot, including acetaldehyde, formaldehyde, methane, ethane, propane, ethylene, propylene, ethyne. Experimental results manifested that technique can notably minimize compared single main injection....
Perovskite type La0·8K0·2MnO3 (LKMO) was prepared by citric acid sol–gel method. X-ray diffraction, SEM and Brunauer–Emmett–Teller were used to characterise the products. The non-thermal plasma assisted catalyst (NPAC) system established combining (NTP) reactor with LKMO catalyst. Following up on bench test, NOx reductions in diesel emissions investigated NPAC system. Results showed that conversion reaches its highest level at 300°C 200°C Improved catalytic properties of can be explained...
A citrate gel process and a assisted dip coating method have been used to prepare the nanocrystalline La0·8K0·2Fe0·5Mn0·45CO0·05O3 (LKFMCO) powders an LKFMCO catalyst. The catalyst was characterised by X-ray diffraction (XRD), scanning electron microscope (SEM), surface area analyzer (BET). Results showed that presented rather irregular porous structure, in which pores were distributed from about 0·5 1·5 μm. Following up on bench test, soot reductions diesel engine exhausts investigated with...
The purpose of this study was to investigate hydrocarbon emissions from the in-cylinder post-injection effect on NO oxidation over a diesel catalyst (DOC) with various feed mixtures. In temperature ramp experiments varying C3H6 concentrations in NO/O2 and NO/O2/H2 mixtures, addition observed inhibit by delaying ignition NO. Furthermore, NO2 production decreased an increase concentration. able reduce platinum oxide produce at 200 °C. Experimental results switching in/out 350 °C indicated that...
A composite oxides’ Co-Mn-Ce catalyst was synthesized by a coprecipitation method, and the experiment carried out to study effects of reaction parameters light hydrothermal aging on propane combustion over catalyst. The influence temperature, concentration, oxygen water vapor, studied during catalytic propane. conversion significantly decreased 10% when concentration increased at 300°C then further from 80% 40% as vapor 0 10 vol.%. In addition, also prolonged time required reach equilibrium....
In this study, the experiments combined with activity tests and characterizations were conducted to investigate influence of hydrothermal aging on reactivity NH3 -SCR over a Cu-CHA catalyst. NOx conversion, N2O production, NO oxidation, adsorption capacity intermediates formation during NH oxidized by NO+O2 comparatively investigated fresh catalysts. The results showed that conversion efficiency below 225°C was well retained while increased in reaction after aging, which associated migration...
