Hydrogen fuel becomes an alternative fuel because of its advantage properties. Hydrogen fuel can be used in form of H2 or HHO. On the dual-fuel systems, hydrogen may be supplied to engines by injectors or by the differential pressure in the intake manifold. This paper presented the applicability of hydrogen on gasoline engines. The paper analyzed and evaluated the methods of hydrogen fuel applications, the results of the performance and engine emissions of the latest researches in over the world. The experiments were performed at hydrogen volume ratio from 1% to 4.5% and different experimental conditions. The experimental results were compared with only-gasoline engines. The combustion cylinders pressure is increased. The thermal efficiency is increased to 7%. The emission of HC and CO emissions are decreased significantly. NOx is reduced at learn conditions and increased at other conditions.

Flexible dual-fuel power technology is becoming increasingly important in a marine market where fuel oil prices are fluctuating and emission legislation is becoming ever more stringent.The advantage of the dual-fuel technology is, without doubt, fuel flexibility. This technology makes it possible to utilise the economic and environmental superiority of gas fuel. The benefits of natural gas are low price and good environmental compatibility, thanks to its clean combustion.The main objective of the present work is to provide a more comprehensive view of the advantages of choosing a dual fuel engine instead of the conventional engine. For this analysis will be considered two ships and will also be taken into account the Energy Efficiency Operational Indicator (EEOI).

Dual-Fuel™ technology combines compression-ignition efficiency with natural gas emissions to create a popular platform for heavy-duty, on-highway, low-emission vehicles. This paper will summarize that technology for on-highway vehicles, benefits to the customer, and commercial issues and trends. Clean Air Partner’s lean-burn Dual-Fuel technology includes electronic control of multi-point, port gas injection, pilot diesel timing and quantity, and lambda (excess air ratio) on a compression-ignition platform. Performance benefits include low emissions plus diesel-like efficiency, power, and torque. There are approximately 1500 CAP Dual-Fuel vehicles on the road in nine countries on four continents. Stringent environmental regulations require new approaches; CAP has developed, adopted, and acquired several technologies to meet this challenge. CAP has also transferred the core Dual-Fuel™ technology from low emissions vehicles to stationary engines for the power generation market.

This paper presents results of investigation of co-combustion process of biodiesel with gasoline, in form of mixture and using dual fuel technology. The main objective of this work was to show differences in both combustion systems of the engine powered by fuels of different reactivity. This paper presents parameters of the engine and the assessment of combustion stability. It turns out that combustion process of biodiesel was characterized by lower ignition delay compared to diesel fuel combustion. For 0.54 of gasoline energetic fraction, the ignition delay increased by 25% compared to the combustion of the pure biodiesel, but for dual fuel technology for 0.95 of gasoline fraction it was decreased by 85%. For dual fuel technology with the increase in gasoline fraction, the specific fuel consumption (SFC) was decreased for all analyzed fractions of gasoline. In the case of blend combustion, the SFC was increased in comparison to dual fuel technology. An analysis of spread of ignition delay and combustion duration was also presented. The study confirmed that it is possible to co-combust biodiesel with gasoline in a relatively high energetic fraction. For the blend, the ignition delay was up to 0.54 and for dual fuel it was near to 0.95.


This research work investigated the diesel engine performance using 20% Pongamia grease methyl ester through the effect of different flow rates of acetylene using dual-fuel technique. Acetylene be inducted within the intake various at the flow rates of 1lpm, 2lpm, 3lpm and 4lpm along with air. Initially a test was conducted by diesel fuel along with POME20 on different loads. Then the experiment was carried out with POME20 with different flow rates of acetylene. Addition of acetylene increased the brake thermal efficiency (BTE) among POME20 at all acetylene flow rates on 100% load. The results showed that the BTE was enhanced via regarding 1–3.4% at knock-limited acetylene shares at 100% load. The engine emits higher NOx emission for POME20 without acetylene share and then it is additional improved with the adding up of acetylene shares, while the smoke opacity was reduced by 47% with acetylene addition at complete load. Here is a decrease in HC as well as CO emissions were experiential through an acetylene orientation along with POME20. Finally, it is suggested that the poor presentation as well as emissions connected through biodiesel into a diesel engine can be improved through the induction of acetylene with 4lpm flow rate in the intake various by dual fuel technology.
