Atkinson cycle

A cycle called the Atkinson cycle is similar to the Otto cycle except that the isochoric exhaust and intake process at the end of the Otto cycle power stroke is replaced by an isobaric process. The schematic diagram of the cycle is shown in Fig. 3.18. The cycle consists of the following four processes ... 

Find the pressure and temperature of each state of an ideal Atkinson cycle with a compression ratio of 8. The heat addition to the combustion chamber is 800Btu/lbm, the atmospheric air is at 14.7 psia and 60°F, and the cylinder contains 0.02 Ibm of air. Determine the maximum temperature, maximum pressure, heat supplied, heat removed, work added during the compression processes, work produced during the expansion...

The engine is 1.81 with an output of 99 hp and 142 Nm on Prius Atkinson cycle, whereas the permanent magnet electric motor is 60 kW/82 hp and 207 Nm. This car allows three types of drive HV, EV and EV-City. The last of the three delays engine operation also in case of firm pressure on the throttle pedal. The Eco Mode modifies the...

There are no published studies of silica on coral reefs. Silica minerals are not abundant on coral reefs, so the biogeochemistry of silica has been ignored. It is evident, however, from the results of our uptake experiments (we measure silica in all our experiments) that silica concentrations in the water sometimes decreases and sometimes increases. This result is probably related to whether benthic diatoms are occupying the reef surfaces. At Biosphere 2 coral reef mesocosm, silica goes through a distinct seasonal cycle related to blooms of benthic diatoms (Atkinson etal., 2001). Concentrations of silica in pore-water can also change seasonally (Falter, 1998). 

Iodine is a basic nutrient compound in the ocean. Iodate (I03) is the oxidized form and abundant in ocean. Iodate is removed by plants, iodide 1 is released and oxidizes chemically and bacterially to iodate. The biogeochemical cycle has not been studied in reef ecosystems, but we believe it will be one of the most interesting. It appears iodate can be removed from the water column by reef communities very rapidly and has rate constants similar to nitrate (Atkinson,...
