Experimental investigations on performance, emission and combustion characteristics of Diesel-Hydrogen and Diesel-HHO gas in a Dual fuel CI engine

Abstract Stringent emission norms being followed throughout the world increases the demand for clean and green fuels. Gaseous fuels like compressed natural gas (CNG), liquefied petroleum gas (LPG) and hydrogen are promising alternatives to conventional diesel and gasoline. The use of hydrogen in the IC engine has gained interest among researchers as it can be […]

Engine performance, emissions characteristics of the compression ignition engine using HHO gas (Brown’s gas)

Abstract HHO gas (Brown’s gas) has recently been used as a new source of energy. The study presents the experimental results at 50% of the accelerator pedal when installed hydroxy (HHO) gas generator on 490 QZL diesel engines. HHO gas was provided into the engine manifold. Comparing the experimental results found that: the economic, technical […]

Assessing the addition of hydrogen and oxygen into the engine’s intake air on selected vehicle features

Abstract Road transport has a significant effect on air pollution. Therefore, the article focuses on the impact of addition of “oxyhydrogen”, known as HHO, on selected vehicle features. These features, on which this study is focused, include the engine power and torque, composition of the exhaust gases and fuel consumption. There was also an impact […]

Emissions and Total Energy Consumption of a Multicylinder Piston Engine Running on Gasoline and a Hydrogen-gasoline Mixture

Abstract A multicylinder reciprocating engine was used to extend the efficient lean operating range of gasoline by adding hydrogen. Both bottled hydrogen and hydrogen produced by a research methanol steam reformer were used. These results were compared with results for all gasoline. A high-compression-ratio, displacement production engine was used. Apparent flame speed was used to […]
