Biodiesel fuels derived from different feedstocks may have significantly fatty acid profiles and physicochemical properties. To gain further insight into the effect of biodiesel chemical structure, specifically its degree unsaturation, on engine performance, combustion characteristics, emissions, an experimental investigation was conducted a high-speed direct-injection automotive diesel fueled with three mixtures methyl esters. The fuel matrix designed such that unsaturation tested isolated....
Tire pyrolysis oil (TPO) is a complex mixture of hydrocarbons (HC), and it one the useful fractions obtained from waste tires (WT). As result its high energy density (HHV ∼ 43 MJ/kg), TPO use as fuel in combustion systems promising approach for recycling WT. However, fundamental characteristics properties are still unexplored, which stand bottleneck potential applications. This work pursues comprehensive understanding structural produced lab-scale twin-auger reactor first step toward...
This work assesses the effect of adding CaO during pyrolysis waste tires (WT) using a twin-auger reactor on properties derived products. Pyrolysis was conducted in lab-scale facility at temperature 475 °C, solid residence time 3.5 min, WT mass flow rate 1.16 kg/h, and N2 300 mL/min. continuously fed ratios 10, 15, 20 wt %, according to rate, two particle size ranges: fine (105–149 μm) coarse (149–841 μm). The resulting tire oil (TPO) initially characterized terms sulfur content, sample with...
Altitude above sea level produces a reduction in air density affecting the combustion process, pollutant emissions, and engine performance. In this work diagnosis of an automotive turbocharged diesel enginewas carried out from in-cylinder pressure signal. Tests were performed at three altitudes level, under steady state operating conditions, using conventional fuel. As altitude increased, fuel/air mixture became richer. The brake specific fuel consumption, duration, premixed phase, maximum...
The development of a steady-state model an Integrated Plasma Gasification Combined Cycle (IPGCC) power plant is presented here. includes the plasma gasifier, syngas conditioning units, and generation unit. Furthermore, each component implemented in Aspen Plus described detail (thermodynamic method, chemical reactions, operative conditions). proposed was validated by comparing gasification results with experimental numerical data from literature; relative error 6.23% 5.24%, respectively. then...
This study aims to establish a baseline of PN emission in the BRT system Bogotá, Colombia. The PN-PTI test was performed 1,474 buses with standards from Euro II-VI, including without DPF, retrofitted and OEM CNG fueled. median DPF is below 3,000 #/cm3. limits such as 1,000,000 or 250,000 #/cm3 cannot detect all mulfunctioning DPF. An additional high-idle proposed for above 50,000 order that may require maintenance. For which are majority bus fleets Latin America, can be used very-high...
This work focuses on the potential for waste energy recovery from exhaust gases in a diesel light-duty vehicle tested under real driving conditions, fueled with animal fat biodiesel, Gas To Liquid (GTL) and fuels. The was following random velocity profiles urban while extra-urban followed previously defined profiles. Tests were carried out at three different locations altitudes. ambient temperature (20 ± 2 °C) relative humidity (50 2%) conditions similar all locations. Exergy analysis...
