The present work describes the numerical modeling of medium-speed marine engines, operating under a fumigated dual-fuel concept, i.e. with the second fuel injected in the ports. Due to the need to reduce engine-out emissions while maintaining engine efficiency, manufacturers are investigating new engine technologies. In the maritime industry, a promising technology to achieve these goals is that of fumigated dual-fuel engines, allowing a large amount of diesel to be replaced by a premixed fuel. To fully optimize the operational parameters of such a large maritime engine, computational fluid dynamics can be very helpful. Accurately describing the combustion process in such an engine is key, as the prediction of the heat release and the pollutant formation is crucial. Auto-ignition of the diesel fuel needs to be captured, followed by the combustion and flame propagation of the premixed fuel. In this work, an approach based on tabulated kinetics has been used, to include detailed chemistry while still maintaining acceptable computation times. To allow for the modeling of a fumigated dual-fuel engine, it has been extending with a…

The present work investigates some recalibration possibilities of a 1.4l common rail turbo-charged diesel engine for the optimal operation in terms of emissions and fuel consumption (FC) with pure Hydrotreated Vegetable Oil (HVO). Initially, steady-state experimental data with nominal engine settings revealed HVO benefits as a drop-in fuel. Under these conditions, pure HVO is associated with lower engine out PM (up to 75%) and CO2 (up to 10%) emissions, and lower mass-based FC (up to 9%), while NOx are similar or slightly higher to diesel fuel. At the next step, a combustion model was developed for the particular engine targeting to identify the optimal IT (Injection Timing) and EGR settings for further emissions (PM, NOx and CO2) and FC reduction with pure HVO. For this purpose, four re-adjusted IT and EGR maps were developed with both conventional diesel and HVO. The results of the combustion model in steady-state conditions showed clear reductions in NOx (up to 45%), PM (up to 70%) and CO2 (up to 6%) emissions and in fuel mass consumed (up to 6%)…

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…

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 (CN 54) and a Naphtha fuel (CN 33) were tested investigating the impact of Ozone in conventional diesel combustion and LTC cases (e.g. high EGR rate). Minimal ozone concentration in the intake flow (10 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 CN 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 UHC produced in…

Due to the potential benefits in lowering of the CO2 emissions and lowering of the cost of fuel, internal combustion engines fueled by natural gas are an attractive alternative to conventional diesel or gasoline engines. In compression ignition engines natural gas is used in a dual fuel combustion mode where the premixed mixture of natural gas and air is ignited by a small amount of directly injected diesel fuel. At constant intake pressure the load is varied by the total fuel mass, i.e. by the excess air ratio, with specific limit on the highest possible excess air ratio. If 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 pressures and excess air ratios. Besides the impact on the combustion the specific combination of intake pressure - excess air ratio also has impact on the exhaust back pressure caused by the turbocharger and consequently on the obtained brake efficiency. In addition to the intake pressure…

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 today’s, 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 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 suggestive of…
