Abstract: A variety of gaseous fuels and a wide range of cooled exhaust gas recirculation (EGR) can be used in turbo-charged spark ignition (S.I.) gas engines. This makes the experimental investigation ...

Abstract: Instead of measuring total ozone by observing the direct sun (if visible) or at the zenith, photometric measurements of sky radiation were made in the solar vertical. The newly developed spectrophotometer uses filters and ...

Abstract: Hydrogen is well recognized as a suitable fuel for spark-ignition engine applications that has many unique attractive features and limitations. It is a fuel that can continue potentially to ...

Abstract: The operation of spark ignition (SI) engines on lean mixtures is attractive, in principle, since it can provide improved fuel economy, reduced tendency to knock, and extremely low NOx emissions. ...

Abstract: The operation of engines whether spark ignition or compression ignition on a wide range of alternative gaseous fuels when using lean mixtures can offer in principle distinct advantages. These ...

Abstract: The knock and combustion characteristics of CO, H2, CH4, and their mixtures were determined experimentally in a variable compression ratio spark ignition (SI) cooperative fuel research (CFR) ...

Abstract: Satellite ozone observations made by the Stratospheric Aerossol and Gas Experiment (SAGE) and corresponding meteorological temperature data are used to study the radiative damping processes associated with planetary waves ...

Abstract: Signs of premature deterioration are customarily observed in areas adjacent to joints in concrete pavements. These areas, especially in cold regions, continue to hold water/solution (due to application of deicing salts) ...
