Experimental investigations carried out in a diesel engine incorporated with Exhaust gas recirculation (EGR), fuelled with the blend of diesel and plastic oil along with an antioxidant additive (p-Phenylenediamine) are presented in this paper. Plastic oil is produced from waste plastics through the process of pyrolysis which could be a potential substitute to fossil diesel in diesel engine applications. Production of plastic oil provides solution to the global twin problems of plastic waste management and energy crisis. Investigations have been carried out with the test fuel separately, test fuel with the additive, test fuel with incorporation of EGR in the engine and test fuel with additive and EGR incorporation. Test results revealed that blend of diesel and plastic oil exhibited performance and emissions at par with pure diesel, 18% reduction in NO emission through EGR incorporation as compared to without EGR and 15% reduction in NO through use of antioxidant additive. It is found that the combined effect of EGR incorporation in the engine and antioxidant additive to the test fuel is a drastic reduction…

In this experimental study, combustion, performance & emission characteristics of a single cylinder D.I. diesel engine is analyzed using lemon grass oil and diesel blend B20. The alumina (Al2O3) nano-particles of 10, 20 and 30 parts per million (B20A10, B20A20, B20A30) are assorted with prepared fuel blend through an ultrasonicator which would help to fetch an unvarying suspension of nano-particles over the blend fuel. SEM analysis and X-ray diffraction have been done for the alumina nano-particles to test the size of the particles that are blended to the bio-fuel blends. The chemical reactivity and rate of mixing are better though the characteristics of nano-particles exhibit high exterior area/capacity ratio during combustion that ultimately results in good characteristics of a diesel engine. Among test fuels, B20A20 shows healthier performance both in relationships of efficiency & emissions such as Nitrous oxide (NOx), hydrocarbon (HC), Carbon monoxide (CO), and Smoke. The ŋBTE for fuel B20A20 is significantly improved by 11.5% when it is compared to the fuel B100. The HC emission is decreased by 40%, CO emission reduced…

Synthetic fuels generated with surplus renewable electricity, water and captured CO2, so called E-fuels, offer the possibility to easily store excess energy over long periods of time. Therefore, the ALIGN-CCUS-project seeks to use them for power-generation and as a fuel for the transport-sector. Polyoxymethylene-dimethyl-ethers (POMDMEs, short: OME) are promising E-fuels for passenger-car applications. Their molecular structure is CH3-O-(CH2O)n-CH3. For passenger-car applications, OME-mixtures with n between 3 and 5 seem most suitable, as the mixture is liquid under normal ambient conditions, offers a high cetane-number and sufficient lubricity. Their high flash-point, low toxicity and good miscibility with conventional diesel-fuel also may ease their market-introduction. The lack of direct C-C-bonds within their molecule and the high oxygen-content lead to very low soot-emissions, thus attenuating the NOx-soot-tradeoff through higher EGR-rates which are required for lowest NOx raw-emissions. However, oxygenated fuels such as OME offer a lower heating value and a different evaporation-behavior compared to conventional diesel-fuel. This leads to differences in spray-formation and ignition-delay. In order to determine the mixture formation characteristics and the combustion behavior of neat…

Literature Review on Dual-Fuel Combustion Modelling

Lund University-Menno Merts, Sebastian Verhelst
Published 2019-09-09 by SAE International in United States
In the search for low greenhouse gas propulsion, the dual fuel engine provides a solution to use low carbon fuel at diesel-like high efficiency. Also a lower emission of NOx and particles can be achieved by replacing a substantial part of the diesel fuel by for example natural gas. Limitations can be found in excessively high heat release rate (combustion-knock), and high methane emissions. These limitations are strongly influenced by operating parameters and properties of the used (bio)-gas. To find the dominant relations between fuel properties, operating parameters and the heat release rate and methane emissions, a combustion model is beneficial. Such a model can be used for optimizing the process, or can even be used in real time control. As precursor for such a model, the current state of art of dual fuel combustion modelling is investigated in this work.The focus is on high speed dual fuel engines for heavy duty and marine applications, with a varying gas/diesel ratio. Modelling is limited to the closed part of the 4-stroke engine cycle. A methodology part…

Experimental Assessment of Ozone Addition Potential in Direct Injection Compression Ignition Engines

IFP Energies nouvelles-Institut Carnot-Michele Bardi, Guillaume Pilla, Mickaël Matrat
Published 2019-09-09 by SAE International in United States
The potential of ozone addition in compression ignition engines is investigated experimentally in this paper. Experiments were carried out in an optically accessible single cylinder engine equipped with a common rail direct injection system. A commercially available ozone generator (P < 100W) was used to add to the intake flow a controlled amount of ozone.EU Diesel fuel (cetane number 52) and a Naphtha fuel (cetane number 33) were tested investigating the impact of Ozone in conventional diesel combustion and LTC cases (e.g. high exhaust gas recirculation rate).Minimal ozone concentration in the intake flow (100 ppm) demonstrated to reduce significantly the ignition delay. However, the impact observed strongly depends on the engine conditions tested and, in general, this effect observed becomes significant in conditions characterized by a long ignition delay: low intake temperature, high dilution, and low cetane number fuel.Significant practical benefits of ozone addition were found for engine cold-start, where ozone yields a significant reduction in misfire events during the first cycle and a faster stabilization of the combustion phasing and a reduction of the…

Experimental and Numerical Analysis of a Dual Fuel Operation of Turbocharged Engine at Mid-High Load

Univ. of Zagreb-Darko Kozarac, Mladen Bozic, Ante Vucetic, Josip Krajnovic, Momir Sjeric
Published 2019-09-09 by SAE International in United States
In the paper the operation of a turbocharged dual fuel engine at mid-high load is investigated on a single cylinder experimental engine complemented by a full 0D/1D simulation model that provides boundary conditions for the experiment and full engine system results. When duel fuel combustion mode is used on a turbocharged engine with the variable geometry turbocharger, the mid-high load operating points can be obtained with number of different combinations of intake pressure and excess air ratio. Besides the impact on combustion, the specific combination of intake pressure - excess air ratio has also impact on the exhaust back pressure caused by the turbocharger and consequently on the obtained brake efficiency. Additionally, the dual fuel combustion is influenced by natural gas mass fraction and start of injection of diesel fuel and the search for the optimal solution could be a challenging task. The method presented here enables the use of a single cylinder experimental engine in this search, while simultaneously taking into account the influences of the effects of a full engine system. The results…

1D Modeling of Alternative Fuels Spray in a Compression Ignition Engine Using Injection Rate Shaping Strategy

Istituto Motori CNR-Ezio Mancaruso, Luigi Sequino
Univ.di Napoli Parthenope, Ist.Mot.CNR-Carmela Perozziello
Published 2019-09-09 by SAE International in United States
The Injection Rate Shaping consists in a novel injection strategy to control air-fuel mixing quality via a suitable variation of injection timing that affects the injection rate profile. This strategy has already provided to be useful to increase combustion efficiency and reduce pollutant emissions in the modern compression ignition engines fed with fossil Diesel fuel. But nowadays, the ever more rigorous emission targets are enhancing a search for alternative fuels and/or new blends to replace conventional ones, leading, in turn, a change in the air-fuel mixture formation.In this work, a 1D model of spray injection aims to investigate the combined effects of both Injection Rate Shaping and alternative fuels on the air-fuel mixture formation in a compression ignition engine. In a first step, a ready-made model for conventional injection strategies has been set up for the Injection Rate Shaping. Experimental data collected in an optical single-cylinder compression ignition research engine via the 2D visible and infrared advanced diagnostic techniques have been used to validate the model. Commercial Diesel fuel has been used. Afterward, two parameters…
