“…The decrease in the combustion rate of diffusive formed mixtures up to 26% with hydrogen fuel was in correlation with the reduction of the smoke emission level; see Figure 10. Similar tendencies regarding the reduction of pollutant emissions levels have been reported in papers describing the effects of hydrogen use in ICE [23,24,[27][28][29][30]52,53,55,56].…”

“…Specifically, by increasing the hydrogen quantity, the peak pressure slightly increases in reduced loading conditions, while it rapidly increases at higher loads. This is a consequence of a smaller delay in diesel fuel autoignition, correlating with the higher combustion rate of hydrogen compared to that of diesel fuel [26,27]. The same trend applies to the maximum pressure rise rate [27,28].…”

The same trend applies to the maximum pressure rise rate [27,28]. Both parameters can be used for hydrogen addition optimization in order to limit mechanical stress on the engine [18,29].…”

Considering the current environmental restrictions, particularly those imposed on fossil fuel exploitation, hydrogen stands out as a very promising alternative for the power and transportation sectors. This paper investigates the effects of the employment of hydrogen in a K9K automotive diesel engine. Experiments were conducted at a speed of 2000 min−1 with various engine load levels of 40%, 55%, 70%, and 85%; several quantities were monitored to evaluate the performance with hydrogen use in terms of brake-specific energetic consumption (BSEC), fuel economy, maximum pressure, and heat-release characteristics. It was found that at 55% engine load, the engine efficiency increased by 5.3% with hydrogen addition, achieving a diesel fuel economy of 1.32 kg/h. The rate of increase of the peak pressure and maximum pressure started to increase as a consequence of the higher fuel quantity that burned in the premixed combustion phase, while still remaining within reliable operational limits. The accelerated combustion and augmented heat release rate resulted in a combustion duration that was reduced by 3° CA (crank angle degree), achieving a mass fraction burned percentage of 10% to 90% earlier in the cycle, and the combustion variability was also influenced. Hydrogen use assured the decrease of CO2, HC, NOx, and smoke emission levels in comparison with classic fueling.

“…Hydrogen has some limitations such as backfire and preignition. Saravanan et al [1] proposed that the direct injection (DI) diesel engine was used to test the performance and emission of an engine. Hydrogen was injected at the intake port of the engine and diesel can be used as an ignition source.…”

The aim of this project is detecting knock during combustion of biodiesel-hydrogen fuel and also the knock is suppressed by timed injection of diethyl ether (DEE) with biodiesel-hydrogen fuel for different loads. Hydrogen fuel is an effective alternate fuel in making a pollution-free environment with higher efficiency. The usage of hydrogen in compression ignition engine leads to production of knocking or detonation because of its lower ignition energy, wider flammability range, and shorter quenching distance. Knocking combustion causes major engine damage, and also reduces the efficiency. The method uses the measurement and analysis of cylinder pressure signal for various loads. The pressure signal is to be converted into frequency domain that shows the accurate knocking combustion of fuel mixtures. The variation of pressure signal is gradually increased and smoothly reduced to minimum during normal combustion. The rapid rise of pressure signal has occurred during knocking combustion. The experimental setup was mainly available for evaluating the feasibility of normal combustion by comparing with the signals from both fuel mixtures in compression ignition engine. This method provides better results in predicting the knocking feature of biodiesel-hydrogen fuel and the usage of DEE provides complete combustion of fuels with higher performance, and lower emission.
