“…Most of the vehicle types, along with passenger cars, are required to satisfy European emission standards. Recently, various effective techniques have been applied to improve engine power and toxic gas emissions, such as optimizing operating parameters like ignition timing, 1 injection timing, 2 compression ratio, air–fuel ratio, and valve overlap. 3 Furthermore, alternative fuels 4 have been investigated as an effective method to reduce toxic gas production and solve the fossil fuel crisis.…”

In this research, we estimated and summarized the effects of combustion duration on the performance and emission characteristics of a spark-ignition engine using pure methanol and ethanol as fuels, which have not been previously presented. From the results, we demonstrated that an increase in combustion duration causes a decrease in peak firing temperature and peak firing pressure and an increase in trapped residual gas. The level of trapped residual gas when using ethanol as fuel is higher than that of methanol fuel. The indicated mean effective pressure (IMEP) and brake mean effective pressure (BMEP) increase to maximum values and then decrease with increasing combustion duration, while the brake specific fuel consumption (BSFC) reaches a minimum value and then increases. The optimal BSFC improved to 33.31% when the engine used ethanol fuel instead of methanol. The increase in combustion duration helps to reduce NO x and HC emissions, but an increase in CO emissions is observed.

“…In the research, a small injection angle was suggested when the injection timing was at a early stage of intake stroke for the ideal fuel distribution. Amrouche et al [21] indicated that the hydrogen-enriched fuel effectively improved the combustion characteristics due to the wide flammability [24,25], small quenching distance [26], high diffusive and flame propagation velocities [27,28], and broadened lean burn limitations [1,29]. Su et al [15] investigated the combustion and exhaust emission characteristics of a hydrogen-blended n-butanol port injection Wankel engine at part load and stoichiometric conditions.…”

Efficiency and emission reduction are the primary targets of internal combustion engine research due the large number of vehicles in operation and the impact of emissions-related pollution on human and ecosystem health. Harmful components of engine exhaust gases include nitrous oxides (NOx), carbon dioxide, hydrocarbons, and particulate matter. NOx emissions in particular are associated with significant health threats. The recirculation of exhaust gases can reduce NOx emissions and improve engine efficiency when combined with other advanced techniques. On the other hand, the residual exhaust gas also effects on the quality of lubricating engine oil and therefore causes an increase in engine piston ring wear. In this review paper, the effects of external and internal exhaust gas recirculation on the performance and emission characteristics of diesel, gasoline, and alternative fuel engines are summarized and discussed in detail. Because it is difficult to estimate the internal residual exhaust gas in the combustion engine by doing experiments. This review paper introduces control strategies and prediction methods for internal and external exhaust gas recirculation.
