“…Non-catalysts using SNCR only use urea or NH3 without catalyst so the cost is low [27]. The reactions occur within certain temperature ranges and the high temperature range for SNCR operation is very narrow, the optimum temperature for effective SNCR is about 900 ÷ 11000C so it should be applied to the exhaust stream having High temperature, stable operation and reasonable SNCR regulator [28].…”

“…The reactions are the same as the SCR but only at the right temperature range, so the range of activity of the SNCR is very narrow, the NOx reduction effect is lower than the SCR but the price is much cheaper because it is not equipped with catalysts. The SNCR system reduces 30-60% of NOx, minimizes the operation of the machine, easy to install, the fact that SNCR is less used than SCR, SNCR mainly applies to boilers where the agent is sprayed directly into Boiler chamber at very high temperature in accordance with SNCR reaction [27]. Chemical methods have the advantage that they can be applied to older engines without affecting the structure of the engine, the engine only needs to be equipped with this device in the exhaust line.…”

Energy in the transportation sector has become a hot issue all over the world because it can affect the energy security of nations. Finding a new type of energy to replace fossil energy is a top concern of many countries, including biofuels. Over the past two decades, there have been many studies on the use of biodiesel and its mix for diesel engines, the results are very positive. In Vietnam, there have also been studies on the use of biodiesel and its mixes on road transport vehicles. However, in the field of waterway transport, there has not been any specific research. Through a comprehensive synthesis of the application situation and research directions in the world, as well as the ability to produce biodiesel in Vietnam, the article wishes to create a premise to develop more research to find develop new technology solutions to apply clean fuels, especially biofuels on the domestic fleet, in line with the development trend of the world on the use of biodiesel fuel.

“…However, concerns over hazardous emissions from shipping on air quality (Viana et al 2014) and on global warming (Taljegard et al 2014) have led to more stringent regulations on emissions, such as sulfur and NO x (IMO MARPOL 2011), and the target to reduce annual global shipping emissions with 50% by 2050 (IMO MEPC 72 2018). Economic studies suggest that internal combustion engines will maintain their leading position over the next decades (Taljegard et al 2014), due to the long operating profiles and the high energy requirement of transport ships, although alternative fuels, such as Liquefied Natural Gas (LNG) (Anderson et al 2015), methanol (Svanberg et al 2018;Amma 2019) and biodiesel (Geng et al 2017;Hoang et al 2019) could reduce the environmental impact of engine emissions.…”

Fast diesel engine models for real-time prediction in dynamic conditions are required to predict engine performance parameters, to identify emerging failures early on and to establish trends in performance reduction. In order to address these issues, two main alternatives exist: one is to exploit the physical knowledge of the problem, the other one is to exploit the historical data produced by the modern automation system. Unfortunately, the first approach often results in hard-to-tune and very computationally demanding models that are not suited for real-time prediction, while the second approach is often not trusted because of its questionable physical grounds. In this paper, the authors propose a novel hybrid model, which combines physical and data-driven models, to model diesel engine exhaust gas temperatures in operational conditions. Thanks to the combination of these two techniques, the authors were able to build a fast, accurate and physically grounded model that bridges the gap between the physical and data driven approaches. In order to support the proposal, the authors will show the performance of the different methods on real-world data collected from the Holland Class Oceangoing Patrol Vessel.

“…Bio-based fuels, with their renewability and other advantages, have been considered a promising candidate. They can be divided by origin, the first being vegetable-oilbased, the second being animal-fat-based and biomassbased (Hoang et al 2019a;Hoang et al 2019b). Among biobased fuel, several researchers about the biodiesel production feedstock and use of biodiesel for diesel engine * Corresponding author: phuong@ut.edu.vn have been studying.…”

Biodiesel, an environmentally-friendly bio-fuel, has been regarded as one of the most promising alternatives to fossil fuels whose use is rampant in the transportation sector. However, it is important that the corrosive effects of this fuel on engines are studied. This work reviews the corrosiveness that biodiesel exerts on various engine components, especially those made out of metals. First, an analysis of the corrosion mechanisms of metals exposed to biodiesel is provided. The conventional and advanced analysis methods will be applied to measure the level of corrosiveness in static immersion test, and to assess the formation of secondary products, if any, in biodiesel and any metal strips in contact with biodiesel-based fuel. The use of inhibitions to guard against corrosion will be mentioned. Lastly, several significant causes of metal corrosion, namely, the presence of dissolved oxygen and oxidation products, TAN change, a rise in dissolved water, the presence of metals, and the changes in biodiesel properties will also be presented. ©2019.
