Unlike the inerting systems on military aircraft, this inerting system runs continuously to reduce fuel vapor flammability whenever the aircraft's engines are running. The goal is to reduce oxygen content within the fuel tank to 12%, lower than normal atmospheric oxygen content of 21%, but higher than that of inerted military aircraft fuel ...
Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704 's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ordinary air.
The stoichiometric air/fuel ratio for hydrogen is 34:1. At this air/fuel ratio, hydrogen will displace 29% of the combustion chamber leaving only 71% for the air. As a result, the energy content of this mixture will be less than it would be if the fuel were gasoline.
If it is to be used as fuel stored on board a vehicle, pure hydrogen gas must be stored in an energy-dense form to provide sufficient driving range. Because hydrogen is the smallest molecule, it easily escapes from containers. Its effective 100-year global warming potential (GWP100) is estimated to be 11.6 ± 2.8.
Hydrogen fuel enhancement from electrolysis (using automotive alternators) has been promoted for use with gasoline-powered and diesel trucks, [14] [15] [16] although electrolysis-based designs have repeatedly failed efficiency tests and contradict widely accepted laws of thermodynamics (i.e. conservation of energy). Proponents, who sell the ...
Methanol reformers are used as a component of stationary fuel cell systems or hydrogen fuel cell-powered vehicles (see Reformed methanol fuel cell). A prototype car, the NECAR 5, was introduced by Daimler-Chrysler in the year 2000. The primary advantage of a vehicle with a reformer is that it does not need a pressurized gas tank to store ...
A Minnesota couple has reportedly been sentenced to four years after they locked their children in cages for "their safety." The couple was arrested and charged with 16 counts in June 2023. They ...
The high compression ratio in the auxiliary combustion chamber causes the auto-ignition of the homogeneous lean air-fuel mixture therein (no spark plug required); the burnt gas bursts - through some "transfer ports", just before the TDC - into the main combustion chamber triggering its auto-ignition.
