What is the effect hydrogen towards ignition delay in diesel? 


Best insight from top research papers

Hydrogen has an effect on the ignition delay in diesel engines. The addition of hydrogen tends to increase the ignition delay of diesel fuel due to both dilution and chemical effects . However, increasing the hydrogen fraction can shorten the fuel ignition delay phase . The simulation results also indicate that a small amount of hydrogen can improve the indicated power of the engine by increasing the in-cylinder pressure . Additionally, the burning rate of diesel fuel is accelerated when mixed with hydrogen, leading to a decrease in combustion duration . Overall, the presence of hydrogen in diesel fuel can affect the ignition delay, with the specific effect depending on factors such as the hydrogen fraction and the engine operating conditions.

What is the temperature of the exhaust of the hydrogen combustion engine.?5 answersThe temperature of the exhaust of a hydrogen combustion engine can vary depending on various factors such as engine load and speed. However, in one study, it was found that the exhaust temperature of a diesel engine, which can be used as a hydrogen combustion engine, ranges from 250°C to 450°C depending on the engine load. Another study proposed an apparatus for estimating the temperature of the exhaust gas in the exhaust manifold of an internal combustion engine. This estimation is based on the temperature increment caused by adiabatic compression and the amount of heat lost in the exhaust gas. Therefore, the exact temperature of the exhaust of a hydrogen combustion engine would depend on the specific engine and its operating conditions.
What is the effect of the mole fraction of hydrogen in a combustion engine?5 answersThe mole fraction of hydrogen in a combustion engine has several effects. Increasing the hydrogen fraction in low calorific value gas fuels can increase laminar flame propagation rate, heat release rate, and engine volumetric efficiency, while reducing engine cycle variation. Co-combustion of hydrogen and diesel fuel in a compression-ignition engine can increase the maximum combustion pressure, rate of heat release, and efficiency, while reducing soot, carbon monoxide, and carbon dioxide emissions. However, it can also lead to a significant increase in HC and NO emissions. Blending hydrogen with gasoline in a direct injection engine can accelerate the combustion process, increase peak heat release rate and cylinder pressure, and enhance knock resistance. Adding hydrogen to a methane-fueled free-piston linear engine can enhance ignition and combustion processes, increase the maximum heat release rate, and affect combustion temperature, NOx, and soot emissions. Hydrogen addition to hydrocarbon and alcohol fuels can increase laminar burning velocity, adiabatic flame temperatures, engine performance, and thermal efficiency, while reducing pollutant emissions.
What is the effect hydrogen towards ignition delay?5 answersHydrogen addition has a significant effect on ignition delay time. The presence of hydrogen in fuel mixtures can promote ignition, leading to a reduction in ignition delay time. The effect of hydrogen on ignition delay is non-linear, with the magnitude of the effect depending on factors such as hydrogen fraction and equivalence ratio. Increasing the hydrogen fraction in mixtures can decrease ignition delay time. However, this effect is more pronounced at lower equivalence ratios and higher temperatures. The addition of hydrogen increases the reactivity of the mixture by increasing the radical pool concentration, which promotes the ignition process. The preferential mass diffusion of hydrogen over other fuel components can also contribute to a reduction in ignition delay time. Overall, hydrogen addition has a complex and non-linear effect on ignition delay time, with the specific impact depending on various factors such as mixture composition and operating conditions.
What is the impact the combustion of natural gas bleended with hydrogen in an oven?5 answersThe combustion of natural gas blended with hydrogen in an oven has been studied in several papers. The results indicate that the impact of hydrogen addition on the combustion performance of the oven burner is minimal up to a certain level of hydrogen concentration. According to the experiments conducted, up to about 15% hydrogen addition by volume does not significantly affect the combustion performance of the oven burner. However, above this amount, flashback in the burner tube becomes a limiting factor. The addition of hydrogen to natural gas also has minimal impact on NOX emissions while decreasing CO emissions. It is important to note that the combustion performance of the oven burner was evaluated based on various parameters such as flashback limits, ignition performance, flame characteristics, combustion noise, burner temperature, and emissions (NO, NO2, N2O, CO, UHC, NH3). These findings suggest that blending hydrogen with natural gas in an oven can be feasible without significant performance impacts, but the concentration of hydrogen should be carefully controlled to avoid flashback and ensure safety.
Which reaction kinetics occur during the combustion of hydrogen?5 answersThe combustion of hydrogen involves several reaction kinetics. One important reaction is the catalytic combustion of hydrogen, which occurs at lower temperatures and allows for the release of heat. Another significant reaction is the chemically termolecular reactions between H + O2 + R, which can affect the global reactivity and burning velocities of hydrogen flames. Additionally, the presence of high concentrations of H2O and CO2 can impact the ignition delay time (IDT) of hydrogen combustion, and a minimally-tuned H2/CO reaction mechanism has been developed to model this behavior. Furthermore, chemically reactive termolecular reactions between radicals and bimolecular complexes have been found to play a role in hydrogen combustion. Overall, the combustion of hydrogen involves a complex interplay of various reaction kinetics, including catalytic combustion, termolecular reactions, and the influence of different species on ignition delay time.
