Hydrogen dual-fuelling of compression ignition engines with emulsified biodiesel as pilot fuel

Hydrogen Use in Internal Combustion Engine: A Review

“…Here water acts in a similar manner to diluents such as EGR, cooling the charge and reducing the combustion rate. However, water injected into the intake manifold reduces volumetric efficiency [24]. Conventional diesel engines can be converted to operate on hydrogen-diesel dual mode with up to about 38% of full-load energy substitution without any sacrifice on the performance parameters such as power and efficiency [25].…”

Effect of hydrogen enrichment on the combustion characteristics of a biofuel diesel engine

“…The point where the pressure curves suddenly rises also indicates the start of combustion [17]. The advantage in attaining peak pressure is due to high rate of pressure rise while inducting hydrogen compared to that of diesel operation [16].…”

A Comparative Study on the Performance and Emission Analysis of a Dual Fuelled Diesel Engine with Karanja Biodiesel and Natural Gas

“…The emission benefits of dual fuel CI engine operation are mainly based on a more homogeneous air-fuel mixture and low temperature combustion operation than in the case of conventional CI engine combustion. [4,5] Among several alternative fuels Natural gas is very promising and highly attractive. Beside its availability in several areas worldwide at encouraging prices, natural gas is eco-friendly fuel that has clean nature of combustion.…”
