12:02 - So by targeting a richer air fuel ratio, that additional fuel actually helps to cool our combustion temperature and that's going to help aid our engine reliability. 12:02 - 因此,通过设定较富的空燃比,额外的燃油实际上有助于冷却燃烧温度,从而有助于提高发动机的可靠性。 12:14 - It'...
2016). Harsh acceleration causes higher fuel consumption and CO2e emissions, mainly due to a richer fuel-to-air ratio needed to avoid engine knocks and overheating of the cylinder head, which increases fuel consumption and CO2e emissions. Furthermore, this richer fuel-to-air ratio persists even...
No clear dependency of this ratio on dissolved concentrations, such as CO or acetic acid concentration, was found. This is largely caused by the lack of knowledge about the dependency of the CO uptake rate (and hence all other rates) on the CO concentration. This knowledge gap is caused by...
Additionally, electricity production and construction costs of the project could again be a disadvantage, according to the respondents: “Energy vs investing ratio could be low.”. For the increase of transmission capacity methods, mainly “costs” were identified as the major disadvantage. Therefore,...
The chapter talks about capacity control and fuel/air ratio control; the four most common fuel/air ratio and capacity control systems are cross-connected systems, single-point parallel-positioning mechanical linkage systems, individual actuator systems, and mass flow control systems.John R. Puskar...
The work:active-rest ratio in the above example is 1:3. Over weeks and months, you increase the work interval and decrease the active rest. For example: Interval 1: 3.5 mph for five minutes to warm up Interval 2: 3.8 mph for two minutes Interval 3: 3.5 mph for two minutes (active ...
Increased compression ratio Higher compression ratios mean higher cylinder pressure and temperature. And again, you may need a colder heat range to rapidly transfer all that extra heat to the cooling system. Supercharging/turbocharging Supercharging forced induction leads to augmented cylinder pressure an...
The ratio of average energy demand to maximum demand for a time period, such as one year, one month, or one hour. An end user with a high load factor uses energy at a consistently higher level year-round than an end user who may use energy specifically for heating or cooling. What is...
Because gas powered RC helicopters are fairly large, and powered by rather heavy two stroke petrol engines, the power to weight ratio of Gassers is fairly low compared to that of nitro or electric. You won't find a gas powered heli for example performing the hard core 3D smacking you see...
The optimized FVD condition followed the one used in Rao et al.’s work46, with 18.4SLPM:12.5SLPM CH4 to air flow ratio and a substrate temperature 550 °C for 10 min of deposition (Supplementary Table 4). W18O49 nanowires were further converted to WO3 nanowires by annealing at 500...
