subtracting the p-value from 1. It is important to note that correlation does not imply causation, but simply the relationship between two values. The quantity of waste heat present in the engine coolant, engine oil, and exhaust gases was of primary interest due to the potential effect on WHR system performance. As shown in Figure 6-1 the heat rejected to the engine coolant decreased as its temperature increased. For example, coolant waste heat decreased from 27.69 ± 2.05% to 11.97 ± 0.62% for the 3100 rpm and 18 N-m torque load point as the coolant temperature was raised from 90°C to 200°C. This trend can be explained by considering the heat transfer from the combustion gases to the cylinder wall. The heat transfer rate is proportional to the temperature difference between the combustion gases and cylinder wall, and the thermal resistance between these two items, and can be expressed as follows: Qw Tg Tw Rcyl Here, the thermal resistance includes both radiation and convection effects [36, 49]: (6.1) (6.2) 1 1 1 h h A Rcyl Rcyl,conv Rcyl,rad As the coolant temperature rises, the ΔT between the coolant and the combustion gases decreases and heat transfer to the coolant drops. Furthermore, the thermal resistance between the gases and the wall also changes, especially because the radiation portion of the thermal resistance increases. In addition, as the engine coolant temperature increases, the temperature of the engine structure increases, which causes increased heat rejection to the environment and the lubrication oil. The engine oil temperature was maintained near 80°C for each test, and, thus, the fraction of fuel energy transferred to the engine oil increased. For example, the oil heat fraction increased from 8.42 ± 0.62% at 90°C coolant temperature to 14.32 ± 1.06% at 200°C for data collected at 18 N-m torque (i.e., a 70% relative increase). The ambient air temperature was also below the coolant temperature, 135 cyl,conv cyl,rad cylPDF Image | WASTE HEAT RECOVERY FROM A HIGH TEMPERATURE DIESEL ENGINE

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
