“…In 1982, the concept of the diesel engine was introduced into the literature with the work of Rudolf Diesel entitled "Working Method Design for Combustion Engines" (Mollenhauer & Tschoeke, 2010). With the construction of a diesel engine onboard a river boat named Vandal in 1903, diesel engines began to be used onboard ships, to the present, diesel engines are used in the vast majority of ships navigating the world (Morsy El-Gohary, 2013).…”

The oil crisis in the world has led countries to seek an alternative fuel that can replace fossil fuels. In addition, the fact that global warming, which is one of the most important problems for the world, has reached significant levels, has led to an increase in studies on greenhouse gas emissions and the efficient use of energy. Every effort to increase efficiency contributes to both environmental and economic improvements. Considering this situation, the study was compiled by examining the studies on energy and exergy analysis related to diesel engines and marine diesel power systems in the literature. As a result of the study, it has been seen that the use of different fuel types contributes significantly to the decrease in environmental emissions as well as the increase in efficiency in diesel engines. In addition, it is thought that there are few studies in the literature on ship diesel engines, and with the increase in the studies to be done on this subject, there may be important references to both companies engaged in maritime transport and studies that will conduct research on this subject.

“…Table 5 shows the inventory for the present study (FU: 1kWh). The marabou harvester considered is the self-propelled biomass harvester BMH480 Kangaroo (diesel-fueled) [70], and the exhaust gas emissions are composed of CO 2 , NO 2 , HC, CO, and PM<10 [71,72]. The consumption of diesel in the transportation stage is modeled on the data provided by Prinoth [70] and EPA [71].…”

“…Transportation is carried out in all scenarios using Kamaz trucks (diesel-fueled), model 5320 at total capacity (8.00E+03 kg) with a fuel consumption index of 2.40-6.00 L/km (empty-full capacity) [75]. The emissions evaluated in the internal combustion engines of these vehicles are CO 2 , CO, volatile organic compounds (VOC), NO 2 , SO 2 , and PM<10 [72,76]. For this scenario, the data were gathered from a previous study [41].…”

Purpose This study aims to assess environmentally three different alternatives related to the valorization of Dichrostachys cinerea (L.) Wight & Arm. (marabou), identified as an invasive tree, as a feedstock for cogeneration facilities installed in the sugarcane industry in Cuba. The alternatives are (A-1) Electricity generation from marabou in a conventional back-pressure steam turbine cycle, (A-2) Electricity generation from torrefied marabou in a back-pressure steam turbine cycle, and (A-3) Electricity generation from torrefied marabou using extraction-condensing turbines.Methods SimaPro 9.0.0.35 software was used for the modeling of the inventory, based on different operational parameters. The ReCiPe environmental impact assessment method was used in the hierarchical perspective, assessing 18 impact categories (midpoint), and 3 damage categories (endpoint).Results and discussion The results demonstrated that A-3 shows the lower environmental impacts (Fine Particulate Matter Formation, Terrestrial Acidification, and Water Consumption) as compared to A-2 and A-1. This performance is explained by a lower normalized marabou consumption (1.85 kg marabou/kWh generated), and lower emissions associated with marabou harvesting, transportation, and processing. The cogeneration stage was the main contributor to the environmental burdens in Water Consumption (100% in A-1; 87% in A-2 and A-3). Marine Ecotoxicity was the impact category with better environmental performance due to the substitution of synthetic mineral fertilizers by ashes produced during combustion. The human health damage category reached the higher impacts on the torrefaction subsystem in the A-3 scenario, representing over 94% of the total environmental burden of the process. PM<10, NO2, and SO2 contributed the most over this damage category, mainly in marabou combustion, causing injuries in respiratory systems by aspiration of organic compounds.Conclusions The use of more efficient technology (extraction-condensing steam turbine), using torrefied marabou as feedstock, compared with the previous alternatives, impacts beneficially on the environment. Thus, a combination of marabou torrefaction with cogeneration facilities in sugarcane industries can be considered as an environmental-friendly technology in the Cuban context. The current study results will help decision-makers implement more sustainable policies in the Cuban energy sector, using marabou as feedstock as an attractive bioenergy route pathway.

“…In the late 1800s when Rudolf Diesel wanted to improve upon the thermal efficiency of the steam engine he settled on a design that relied on high compression of the air in the cylinder to selfignite the fuel and the diesel engine was born. 1 The ability to operate at high air-to-fuel ratios make diesel engines particularly cost efficient for the amount of work produced and they are still the engine of choice for large on-and off-road vehicles, locomotives, and ships. 2 The utilization of diesel engines in passenger cars did not occur until the 1930s and remained relatively small until the 1990s.…”

On-Road NO_x Emissions Evaluation of the Repair Effectiveness for Recalled Volkswagen Group Light-Duty Diesel Vehicles in the United States

The admission by the Volkswagen Group in the fall of 2015 that they had duped the United States new vehicle emissions certification testing resulted in perhaps the most expensive violation of U.S. environmental vehicle emission regulations in its history. As part of the subsequent recall of more than 500 000 vehicles in the U.S., owners could sell their vehicles back to the companies or have them repaired. We have used a number of large on-road emission measurement data sets that were routinely collected before and after the recall to evaluate the fuel specific NO x emissions benefit for the vehicles that were repaired and remained in service. We found that onroad fuel specific NO x emissions were reduced by 83% from the prerepair group. The reductions increased to 91% if we only compare with vehicles that were fully repaired. NO 2 emissions were dramatically reduced by an even larger percentage >95%. We find that the repairs resulted in fuel specific NO x emissions that are comparable or slightly lower than in-use light and medium-duty diesel trucks measured in Denver in 2020 indicating the repairs were a success.
