“…Figure 12 shows the variation of HC emission with respect to engine load. In a diesel engine, HC emission rises due to the incomplete combustion of fuel [18]. The maximum concentration of 48 PPM was liberated from the diesel engine at full load conditions.…”

Diesel-powered transportation is considered an efficient method of transportation; this sees the increase in the demand for the diesel engine. But diesel engines are considered to be one of the largest contributors to environmental pollution. The automobile sector accounts for the second-largest source for increasing CO2 emission globally. In this experiment, a suitable postcombustion treatment to control CO2 emission from IC engine exhaust is developed and tested. This work focuses to control CO2 emission by using the chemical adsorbent technique in diesel engine exhaust. An amine-based liquid is used to adsorb the CO2 molecules first and absorb over the amines from the diesel engine exhaust. Three types of amino solutions (L-alanine, L-aspartic acid, and L-arginine) were prepared for 0.3 mole concentrations, and the CO2 absorption investigation is performed in each solution by passing the diesel exhaust. A suitable CO2 adsorption trap is developed and tested for CO2 absorption. The experiments were performed in a single-cylinder diesel engine under variable load conditions. The eddy current dynamometer is used to apply appropriate loads on the engine based on the settings. The AVL DIGAS analyzer was used to measure the CO2, HC, and CO emissions. An uncertainty analysis is carried out on the experimental results to minimize the errors in the results. The effective CO2 reduction was achieved up to 85%, and simultaneous reduction of HC and CO was also observed.

“…The CO emissions were also produced with carbon which was from the diesel combustion assisted with hydrogen combustion after the diesel ignition. However, the CO emissions were produced from incomplete combustion (Hariharan et al, 2021). In summary, the configuration of the diesel engine operating conditions was highly related to the utilization of the oxy-hydrogen gas injection parameter.…”

Reducing carbon emissions such as carbon dioxide (CO2) and carbon monoxide (CO) from diesel engines struggled with engine performance challenges and fossil fuel limitations. Besides, huge transportation such as ships hardly replaced diesel engines due to the higher thermal efficiency and low operation cost. Oxy-hydrogen gas, as a carbon-free gas, could potentially improve diesel engine performance and carbon emissions. Most of the studies tried to identify the effect of oxy-hydrogen induction into diesel engine combustion on performance and emissions. However, this study evaluated oxy-hydrogen injector sizes to the diesel engine performance and carbon emissions at several loads and several engine speed conditions. Overall, the result showed that the oxy-hydrogen gas injection into the diesel engine’s intake port improved the performance and carbon emissions compared to the single diesel fuel as a baseline. High engine performance with low carbon emissions could be achieved at low and medium engine load conditions with high engine speeds. Moreover, smaller oxy-hydrogen injector sizes were suitable for the medium engine load and vice versa, to improve the performance and carbon emissions. At low load, the engine performance improvement of engine torque, specific fuel consumption, and thermal efficiency were 1800 to 2200 rpm. Moreover, the CO2 and CO emissions reductions were also suitable with 2200 rpm with a bigger oxy-hydrogen gas injector (6 mm). Furthermore, at medium load, the engine performance improved at 1400 rpm but the CO2 and CO emissions were lower at 2200 rpm with a small oxy-hydrogen gas injector (4 mm). The engine operation at 2200 rpm with a 4 mm injector also improved the engine performance regarding carbon emissions reduction. However, injecting oxy-hydrogen gas into diesel engines had the potential to enhance the engine performance and reduce carbon emissions, moving closer to achieving zero emissions

“…10 shows the variation of exergetic efficiency with respect to the acetylene premixed ratio and equivalence ratio. The exergetic efficiency has been calculated on the basis of eqn (3). The exergetic efficiency tells us about the maximum work output that can be extracted while running the engine with a particular set of fuels and also about the best strategy of operation where maximum output can be attained.…”

“…It is well known that the conditions for the production of NO x and PM are just inversely related in the case of conventional diesel combustion. 3 Better combustion results in high cylinder temperature and, thus, higher NO x is produced, whereas a trial of controlling NO x emission leads to incompleteness in combustion and higher hydrocarbon, and PM emissions. 4 Significant hardware development like CRDI has provided dramatically superior control over fuel consumption and emissions by increasing combustion efficiency in the past decade.…”
