Gasification involves turning organic fuels (such as biomass resources) into gaseous compounds (producer gas or syngas) by supplying less oxygen than is needed for com­ plete combustion of the fuel. Gasifica­ tion occurs at temperatures between 1112o and 2732o F and produces a lowto medium-energy gas depending upon the process type and operating conditions. Gasification of biomass resources is ...

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

Biogas is competitive, viable, and generally a sustainable energy resource due to abundant supply of cheap feedstocks availability wide range biogas applications in heating, power generation, fuel, raw materials for further processing production chemicals including hydrogen, carbon dioxide biofuels. The capacity based has been growing rapidly the past decade with global electricity generation i...

The aim of the research is to test the fuel additives which decrease dimensions of atomised fuel drops, by applying changes to the specific parameters which impact the atomisation process. Those parameters include density, surface tension, viscosity and the viscosity index. Dimensions of drops of biofuels are much bigger compared to hydrocarbon fuels. By modifying the physical and chemical para...

Nowadays, the environmental impact of shipping constitutes an important challenge. In order to achieve climate neutrality as soon possible, priority consists progressing on decarbonization marine fuels. Free-carbon fuels, used single fuel or in a dual-fuel mode, are gaining special interest for engines. A dual ammonia-diesel operation is proposed which ammonia introduced with intake air. Accord...

In this study, performance and combustion characteristics of dual fuel operations (biogas, biogas+hydrogen) were experimentally analyzed compared with corresponding baseline diesel in four-cylinder, common-rail engine without thermal barrier coated piston. Tests conducted at three different loads (50 Nm, 75 100 Nm) a constant speed 1750 min-1. Engine pistons Yttria Stabilized Zirconia material ...

Ammonia, as an alternative fuel for internal combustion engines, can achieve nearly zero carbon emissions. Although the development of pure ammonia engine is limited by its poor characteristics, ammonia–hydrocarbon mixed effectively improve fuel. With increase in proportion mixture, a large number nitrogen oxides (NOX) and unburned may be discharged, which have impact on environment. In this st...

Different optical techniques were applied to describe the thermal and chemical processes that occur in a SI small engine from the ported fuel injection and in-cylinder mixture formation to the combustion process and the exhaust emission. In PFI SI engines, the atomized fuel is sprayed towards the intake valves, where it may evaporate, puddle or rebound. Furthermore, a portion of the fuel may fl...
