“…Especially the fuel bound oxygen plays an important role for a more completed soot oxidation. This was also the conclusion in [28] [29] [3]. Figure 10 represents the integrated intensity during the combustion (not included end of combustion) and corresponds to the area under the graph in Figure 9 for 1000 bar.…”

Maritime environmental regulations stipulate lower emissions from the shipping industry. To cope with these rules, improving the combustion processes, make use of cleaner alternative fuels and implement exhaust gas cleaning systems is necessary. Alternative fuels, like fish oil, have a potential to reduce soot formation during the combustion process and will be deeply investigated in this paper. For this purpose, two different types of fish oil and their blends with marine gas oil (MGO) have been tested in a constant volume pre-combustion cell (CVPC). The CVPC laboratory was built in collaboration between MARINTEK and NTNU. To generate similar injection condition in the combustion cell as in an internal combustion engine, the CVPC is heated using a chemical heating process. The CVPC is used as a fundamental investigation tool for studying the fuel injection system for large engine applications. Parameters that were studied include the combustion, spray development, fuel evaporation process and ignition delay. The general experimental setup of the test facility is described and the optical methods applied are explained for the investigation of fish oil. The aim is to study soot intensity and spray development and to compare the results to pure low-sulphur MGO as a reference fuel. The results conclude that the combustion and ignition properties of fish oil are very similar to marine gas oil and this makes it applicable as an alternative fuel for power generation in the maritime industry. The tests also showed a significant decrease in soot formation for the two fish oils.

“…The well-known NO x versus particle trade-off in diesel combustion leads to the need of either a NO x or a particle exhaust gas after-treatment system if demanding exhaust gas emission limits have to be met. Future emission limits include, besides of strict particle mass limit values, also particle number limit values which will very likely enforce the use of combined NO x and particle exhaust gas after-treatment systems (Soltic et al, 2009). The pollutant emissions are calculated according to Directive 2005/55/EC and its amendments.…”

“…This leads to the need of adding exhaust gas aftertreatment for the NO x and adjusting the engine parameters to meet these limits for new engines. Soltic et al (2009) shows an experience with a heavy-duty on-road engine with exhaust gas aftertreatment, running with SVO from rapeseed that meets the German pre-standard DIN V 51605. This work demonstrates that similar and even lower emissions for SVO compared to diesel can be achieved by engine parameter optimization for SVO and the use of an oxidation catalyst and a diesel particulate filter (DPF).…”

“…cetane number, density, viscosity, heating value, lubricity, boiling behaviour-, when using SVO in diesel engines, only small modifications of the engine are required (Soltic et al, 2009). However, SVO has different chemical and physical properties compared to mineral diesel fuel which have to be considered and regulated.…”

Small-scale production of straight vegetable oil from rapeseed and its use as biofuel in the Spanish territory

et al. 2010

View full text Add to dashboard Cite

Biofuels nowadays are an important topic of study. The most significant point is the availability of bioethanol or biodiesel and their production from different raw materials. It is already known that large scale production of first-generation biodiesel cannot be seen as an alternative to fossil fuels due to land requirements, competition with food, increase in fertilizer requirements and pressure on tropical forests among others. This fact does not necessarily apply to second-generation biofuels or small scale niche productions. Straight vegetable oil (SVO) can be used directly in diesel engines with minor modifications. Our proposal is a small-scale SVO production system for self-supply in agricultural machinery. In this paper a model to provide SVO to local farmers in a specific area in Catalonia (Spain) is presented. We also present a discussion about the regulations to be changed in order to make possible the incorporation of SVO as engine fuel in diesel vehicles and a comparative analysis between the emissions of tractors fed with SVO and petrodiesel. Moreover a quantitative economic analysis of modifying diesel engines and long-term operability costs are shown and a firstrun economic analysis comparing the actual crop rotation with the proposed one and some alternatives is studied.

“…Biodiesel is the most important type of alternative fuels used in compression ignition engines because of its advantages in terms of emission reduction without significant changes to engine layout [3,4,5] and, at the same time, for being partly bound by future European legislation [6]. Anyway, several studies showed that the impact of biodiesel on the modern diesel engines is significant also in terms of engine performance mainly because of the interaction between the biodiesel characteristics and the engine-management strategies [7,8]. One of the main differences of FAME with respect to petro-based diesel fuel is its oxygen content.…”

Biodiesel- Quality, Emissions and by-Products

View full text Add to dashboard Cite

This book entitled "Biodiesel: Quality, Emissions and By-products" covers topics related to biodiesel quality, performance of combustion engines that use biodiesel and the emissions they generate. New routes to determinate biodiesel properties are proposed and the process how the raw material source, impurities and production practices can affect the quality of the biodiesel is analyzed. In relation to the utilization of biofuel, the performance of combustion engines fuelled by biodiesel and biodiesels blends are evaluated. The applications of glycerol, a byproduct of the biodiesel production process as a feedstock for biotechnological processes, and a key compound of the biorefinery of the future is also emphasized.
