“…In both cases, there was also a decrease in engine performance and an increase in carbon dioxide (CO 2 ) and NO x emissions with reduced CO emissions. It turns out that the biggest disadvantage of using hydrogen for co-combustion with biodiesel is the increase in nitrogen oxide emissions due to the higher temperature of combustion in the engine's cylinder [16,17]. However, for small and medium loads, replacing diesel with biodiesel and co-combustion it with hydrogen with a large share of exhaust gas recirculation (EGR) contributes to reducing NO x emissions and keeping a constant level of soot emissions [18].…”

The paper presents the results of co-combustion of biodiesel with hydrogen in a compression-ignition internal combustion engine. The tests were carried out on a stationary engine with constant settings. The paper presents the results of the assessment of the combustion process, combustion stability and exhaust emissions in a dual-fuel diesel engine fueled with biodiesel and hydrogen. It was found that it is possible to replace biodiesel with hydrogen to its energetic share of 38%. The share of hydrogen in the co-combustion process causes a change in combustion phases and reducing the duration of combustion. The increase of the engine thermal efficiency was obtained with the increase of the H2 share. A different character of heat release rate was obtained compared to a conventional engine. The reduction in the diffusion combustion phase has contributed to a significant reduction in soot emissions. The maximum 38% of hydrogen energy share acceptable by the engine, resulted in a more than 25-times reduction in soot emissions. The combustion stability assessed on the basis of the unrepeatability of the indicated mean effective pressure (COVIMEP) index and also on the basis of the indicated mean effective pressure (IMEP) normal distribution was also analyzed.

“…Biodiesel is an environmentally friendly, renewable fuel which can be used in any compression ignition engine to substitute diesel fuel. Chemically, biodiesel contains a mixture of methyl esters with long-chain fatty acids, and is typically derived from nontoxic biological resources, such as vegetable oils [35][36][37][38][39], animal fats [40][41][42][43][44][45][46], or even cooking oils [47][48][49][50]. While many recent works analyzed the effects of biodiesel on the injection process, spray formation, and combustion [51][52][53][54][55][56], this section will emphasize the potential of different biofuel blends in reducing the noise and chemical pollutions of ICEs.…”

Performance Enhancement of Internal Combustion Engines through Vibration Control: State of the Art and Challenges

et al. 2019

Internal combustion engines (ICEs) are the primary source of power generation in today’s driving vehicles. They convert the chemical energy of the fuel into the mechanical energy which is used to drive the vehicle. In this process of energy conversion, several parameters cause the engine to vibrate, which significantly deteriorate the efficiency and service life of the engine. The present study aims to gather all the recent works conducted to reduce and isolate engine vibration, before transmitting to other vehicle parts such as drive shafts and chassis. For this purpose, a background history of the ICEs, as well as the parameters associated with their vibration, will be introduced. The body of the paper is divided into three main parts: First, a brief summary of the vibration theory in fault detection of ICEs is provided. Then, vibration reduction using various mechanisms and engine modifications is reviewed. Next, the effect of using different biofuels and fuel additives, such as alcohols and hydrogen, is discussed. Finally, the paper ends with a conclusion, summarizing the most recent methods and approaches that studied the vibration and noise in the ICEs.

“…However, it is time to search for the alternative renewable biodiesel as the efficient fuel that helps to minimize the excessive use of conventional diesel depends on the increase of need (Ramesh et al, 2018;Wu et al, 2017;Hosseini et al, 2017). Regarding the regulatory framework, new regulations for the construction of diesel engines are updated and adapted, that allow complying with the regulations of atmospheric pollutants emitted by the combustion of diesel, and whose main objective is to take care of the environment (Efe et al, 2018;Akar et al, 2018).…”
