An Investigate on Power, Torque and Exhaust Gas Emission Variation: Effect of Hydroxy Gas Addition to Inlet Air of a SI Engine
Hydrogen has been known as a clean and suitable fuel to replace conventional fossil fuels. One of the common hydrogen production methods is using water electrolysis process. This method produces oxygen as well as hydrogen by ratio of 1:2. The aim of this work is to investigate the effects of inlet air enrichment by adding produced hydrogen and oxygen to an internal combustion engine. For this p...
متن کاملEffect of Dissolved Oxygen and Chemical Oxygen Demand to Nitrogen Ratios on the Partial Nitrification/Denitrification Process in Moving bed Biofilm Reactors
Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewaterwith high ammonium concentration or low C/N ratio. In this study, the effect of dissolved oxygen (DO)and influent ratio of chemical oxygen demand to nitrogen (COD/N) ratio on biological nitrogen removal fromsynthetic wastewater was investigated. Experiments were c...
متن کاملComparison of the Effects of Hydrogen and Hydroxygen Additions and Oxygen Enrichment on the Emission Characteristics of EF7 Engine
In this study, the effects of hydrogen and hydroxygen additions and oxygen enrichment on the emission characteristics of a gasoline engine (EF7) were investigated and compared with each other. The simulation was launched by GT-Power at different engine speeds with 5 % to 15 % volume fractions for both of oxygen and hydrogen enrichment and 4.5 % to 9 % volume fractions of hydroxygen addition in ...
متن کاملThe spring bloom in the northwestern Sargasso Sea: spatial extent and relationship with winter mixing
The interannual variability of the spatial extent of the spring bloom in the central Sargasso Sea was quantified by remote-sensing approaches. Proxy measurements employing satellite-derived sea-surface temperature and chlorophyll a concentrations were used to estimate the amount of new production derived from inorganic nitrate supplied by convective winter mixing. Nitrate supply and new product...
متن کاملInvestigation of Auto Ignition Condition under Different Parameters
In this work, the potential of auto-ignition of heavy oil during in-situ combustion (ISC) process was studied. Kinetic studies were carried out using Thermo Gravimetric Analyzer (TGA), Differential Scanning Calorimetry (DSC) and Accelerating Rate Calorimetric (ARC) techniques. Effects of oxygen partial pressure, reservoir pressure and clay on auto ignition condition were investigated on a n...
