It is well known that hydrogen addition to spark-ignited (SI) engines can reduce exhaust emissions and increase efficiency. Micro plasmatron fuel converters can be used for onboard generation of hydrogen-rich gas by partial oxidation of a wide range of fuels. These plasma boosted microreformers are compact, rugged, and provide rapid response. With hydrogen supplement to the main fuel, SI engine...

This works aims to provide an understanding on basic chemical kinetics pertaining three-way catalytic (TWC) converters from educational perspective, aimed at those novel readers in this field. Rate of reactions and its factors are explained, showcasing that the chosen catalyst is main factor affecting overall rate reaction. Furthermore, overview revisit insights converter structure environmenta...

Emission regulations for diesel engines are being strengthened and it is impossible to meet the standards without exhaust after-treatment systems. Lack of the space in many diesel vehicles, however, make it difficult to design and install stand-alone catalytic converters such as DOC, DPF, and SCR in the vehicle exhaust systems. Accordingly, those have been installed inside the muffler to save t...

The world’s rapidly dwindling crude oil supplies, their rising cost and the rapid growing of automobile pollutions from fossil fuels have led to an intensive search for alternative fuels. Experiments were conducted to evaluate the performance and control the exhaust emissions from two-stroke, single cylinder, spark ignition (SI) engine, with alcohol blended gasoline (80% gasoline and 20% ethano...

We investigated the biochemical and biophysical properties of one of the four alternative regions within the Drosophila myosin catalytic domain: the relay domain encoded by exon 9. This domain of the myosin head transmits conformational changes in the nucleotide-binding pocket to the converter domain, which is crucial to coupling catalytic activity with mechanical movement of the lever arm. To ...
