“…Although the use of lemongrass oil is perfect for reducing emissions, however, the price is still too high for fuel. Investigation of emissions on diesel engines has been carried out with a variety of different fuels [40][41][42]. However, the emission results shown in several previous studies have resulted in higher emissions than in this article.…”

The emissions generated from vehicle engines are one of the problems of global warming worldwide. Conventional oil depletion globally has encouraged various researchers to look for alternative fuel solutions as a substitute for petroleum. Various studies on additive fuels have also studied and most of the fuels have shown perfect results. In this experiment, citronella oil blended into pure diesel fuel to investigate emissions and fuel consumption in a single-cylinder diesel engine. Citronella oil used for diesel fuel blends as much as 0.5%. This test carried out on a single-cylinder engine with three loads (25%, 50% and 75%) and different engine speeds. The results of experiments with diesel-citronella fuel show CO2 emissions lower than pure diesel. Reduction of CO2 emissions from the diesel-citronella mixture for engine loads 25% (0.4%), 50% (0.8%) and 75% (1.9%), respectively. While diesel-citronella fuel blend consumption is higher than pure diesel for each engine load and all speeds tested. Overall diesel-citronella mixed fuel for all tests showed better results compared to pure diesel.

“…While the diesel fuel ignites the mixture at lower temperatures, the substituted hydrogen reduces the overall emissions. At high engine loads, this has no negative effects on the brake thermal efficiency (BTE), while at low-to midrange engine loads, the BTE decreases [31,32]. Exhaust gas recirculation was shown to greatly reduce the nitrogen oxide emissions of dual fuel hydrogen engines, which are a big problem for any engine operating at high temperatures [32].…”

Exhaust gas recirculation was shown to greatly reduce the nitrogen oxide emissions of dual fuel hydrogen engines, which are a big problem for any engine operating at high temperatures [32]. While it was shown that it is possible to run hydrogen in a diesel combustion process by itself using either air preheated to 200 • C or glow plugs resulting in thermal efficiencies varying between 32 and 49% depending on the engine load, this approach could not be found in recent publications [33].…”

Climate change is one of the major problems that people face in this century, with fossil fuel combustion engines being huge contributors. Currently, the battery powered electric vehicle is considered the predecessor, while hydrogen vehicles only have an insignificant market share. To evaluate if this is justified, different hydrogen power train technologies are analyzed and compared to the battery powered electric vehicle. Even though most research focuses on the hydrogen fuel cells, it is shown that, despite the lower efficiency, the often-neglected hydrogen combustion engine could be the right solution for transitioning away from fossil fuels. This is mainly due to the lower costs and possibility of the use of existing manufacturing infrastructure. To achieve a similar level of refueling comfort as with the battery powered electric vehicle, the economic and technological aspects of the local small-scale hydrogen production are being investigated. Due to the low efficiency and high prices for the required components, this domestically produced hydrogen cannot compete with hydrogen produced from fossil fuels on a larger scale.

“…The experimental setup was designed to study the net potential of waste heat recovery from engine exhaust. Moreover, the other important feature was its implementation in cooling the exhaust gases for exhaust gas recirculation (EGR) for limiting emissions of oxides of nitrogen (NOx), which has been published elsewhere (Nag et al 2019). Figure 12.3 shows the schematic diagram of the experimental setup for exhaust heat recovery.…”

This study aims at energy harvesting mufflers that utilize thermoelectric generators (TEG) to convert waste heat from the engine exhaust into electricity and simultaneously reduce engine noise. The recovered electricity can be used to power the auxiliary units in the automobile and can effectively improve the overall efficiency of the system. In this study, an automotive exhaust thermoelectric generator (AETEG) unit is fabricated to extract the waste exhaust heat from the engine. To further enhance the performance of AETEG unit, changes in the internal geometry of the unit are proposed, and a systematic computational study is carried. Investigation results indicate that transformations in the internal geometry enhance the heat transfer rate due to lower flow stratification and induced turbulence. This shows increasing potential for higher electricity generation. However, an increase in backpressure due to flow obstruction remains a problem with increasing baffle count. The internal geometry with six baffles gave the best thermal performance with backpressure within acceptable limits for the studied cases. Additionally, that AETEG unit serves as a noise muffler and attenuates the exhaust noise by 53 dBA.
