Abstract—Producer gas is a biomass derived gaseous fuel which is extensively used in internal combustion engines for power generation application. Unlike the conventional hydrocarbon fuels (Gasoline and Natural gas), the combustion properties of producer gas fuel are much different. Therefore, setting of optimal spark time for efficient engine operation is required. Owing to the fluctuating ten...

To meet the target of reducing greenhouse gas emissions, hydrogen as a carbon-free fuel is expected to play major role in future energy supplies. A challenge with its low density and volumetric value, meaning that large tanks are needed store transport it. By injecting into natural network, transportation issue could be solved if hydrogen–natural mixture satisfies grid quality requirements set ...

the first step in dealing with the behavior of an engine on ng mode is the installation of a suitable gas fueling system on the engine. two generations of gas fueling systems which were studied and installed on research engine were mixer type and sequential system type. the results, including performance, emissions and fuel consumption, were recorded and analyzed. the results showed that the se...

The development of Crush Natural Gas (CNG) Engine Control Unit (ECU) depends on expensive bench tests or traditional gasoline engine simulation software, which expand researching and developing period. A new approach is presented in this paper, in which a novelty CNG Turbo engine model based on Mean Value Model and Hardware In Loop (HIL) platform are included. The model acts as many roles e.g. ...

The dual-fuel diesel engine (D.F.D.E) is a conventional diesel engine in which much of the energy released, hence power, comes from the combustion of gaseous fuel such as natural gas. The exhaust emission characteristics of the D.F.D.E needs further refinements, particularly in terms of reduction of Unburnt Hydrocarbons (U7HC) and Carbon Monoxide (CO) emission, because the concentration of thes...

Increasingly restrictive emission regulations and renewed focus on energy efficiency drive the current researches to find alternative fuels and their related better combustion strategies. In this regard, dual fuel engines, in which natural gas fuel is used as a main fuel and diesel fuel is employed as a pilot fuel, have received considerable attention. However, poor fuel utilization efficiencie...
