Electrical-to-thermal energy conversion efficiency - defined here as the thermal energy deposited into the gas ([E.sub.therm]) normalized by the pulse electrical energy delivered ([E.sub.elec]) to the igniter - was determined for each discharge.
However, for additionally examining vehicle performance in the energy conversion efficiency and tractive energy domain, fuel economy and tailpipe C[O.sub.2] emissions must first be converted from their native units into a common energy-based metric.
However, those researches lack discussion of how to improve the EM energy conversion efficiency. In addition, the establishment of a control map requires extensive experimental data as a practical foundation (which means it would be difficult to use in product development phases of the vehicle).
Amorphous silicon technology is less widespread, as it offers lower efficiency, lower longevity, and higher degradation rates than its competitors [International Energy Agency 2014], Although First Solar has steadily improved the average energy conversion efficiency of its cadmium telluride solar modules to more than 14.0 percent, plummeting polysilicon prices in recent years have reduced thin-film modules' cost advantage.
Under illumination with a simulated solar light of 100 mW [cm.sup.-2] (AM 1.5), the photovoltaic parameters of the DSSCs including short circuit photocurrent density ([J.sub.SC]), open circuit voltage ([V.sub.OC]), FF, and the light-to-electric energy conversion efficiency ([eta]) are listed in Table 2.
Their usage is limited because of the low energy conversion efficiency and high costs.
As for bare solar cells, the average energy conversion efficiency of 20 cells after 500 h of exposure degraded by 5-6%, which is higher than the data of sealed cells.
Three papers from Yunnan Normal University produce fatty acids from soybean oil through lipase catalysis, assess the inhibition effect of fusarium oxyspomm with bioslurry, and measure the energy conversion efficiency of sorghum distilled residue biogas fermentation.
The energy conversion efficiency from electrical energy from the grid to turning the wheels for electric vehicles is about three times greater compared to the energy conversion efficiency from the energy stored in gasoline to turning the wheels for gasoline vehicles.
Energy conversion efficiency is very important for the solar power generation system.
For example, in the PV sector, there is a growing emphasis on energy conversion efficiency as solar subsidies begin to go away and as panel prices are on a relentlessly downward trend.
Both energy conversion efficiency and C sequestration by bamboo forest in subtropical China (Table 2) were quite high.
