“…It indicated that brake thermal efficiency of this engine fuelled with hydrogen was approximately 2% higher than that of gasoline; however, the maximum NO x concentration of hydrogen fuel combustion was more than four times higher than that of gasoline, caused by high in-cylinder temperature. Açıkgöz et al [28] also demonstrated that hydrogen additions effectively increased the brake thermal efficiency of IC engines and decreased CO 2 , HC, and CO emissions [28], which was consistent with other researches [29][30][31].…”

The objective of the present work is to evaluate the performance of a low-cost tractor equipped with a parallel hybrid engine, which was simulated using AMESim software. The tractor was evaluated with three different farming implements attached to the tractor, and each implement requires a different type of power. The first simulation was executed without any implements attached. The tractor was able to run for 170 s with the electric motor only, which resulted in fuel savings during this period. The first implement, a moldboard plow, was attached for the second round of evaluation, and the electric motor ran by itself for 150 s, which also led to fuel savings during operation. During the third simulation, the tractor was attached to a Bette Harvest, which has a very high-power demand. The obtained results show that both engines were engaged to provide the required energy. During the final round of evaluation, simulations were run for a straw tub grinder. In this simulation, the electric motor ran alone until the battery was fully discharged. Thereafter, the combustion engine was activated in order to facilitate operations and to charge the battery. The results show that the parallel hybrid architecture employed for the low-cost tractor significantly decreased the CO2 emissions and minimized the consumption of fuel.

“… 12 , 13 Compared with traditional fuels, such as gasoline and diesel, hydrogen exhibits the features of a higher laminar flame velocity, shorter quenching distance, and higher diffusion coefficient. 14 , 15 However, hydrogen as an engine fuel also faces problems such as safety, preignition, backfire, and power reduction. It can effectively improve fuel vaporization and mixture, speed up combustion, and decrease cold wall quenching and cyclic variations when hydrogen is introduced into a gasoline engine.…”

To explore the effect of hydrogen blending on the combustion of a gasoline direct injection engine, a three-dimensional model of the engine is built. The effects of some hydrogen volume fractions (HVFs) and ignition timings (ITs) on the engine performance parameters are studied. Furthermore, the microstructure and mechanism of combustion are analyzed. The simulation results reveal that when the gasoline engine is blended with hydrogen, the active hydroxyl radical concentration increases, and the combustion process is accelerated. When the IT is fixed, with the HVF rising, the peak heat release rate and cylinder pressure will increase. The ignition delay, combustion duration, and crank angle when cumulative heat release reaches 50% decrease. Additionally, the autoignition is shifted to an earlier time as the IT advances. Under the studied conditions with the increase in the HVF, the knock resistance is enhanced because hydrogen has a high knock resistance and octane number.
