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 ...
Oxy-fuel processes may use a variety of fuel gases (or combustible liquids), the most common being acetylene. Other gases that may be used are propylene, liquified petroleum gas (LPG), propane, natural gas, hydrogen, and MAPP gas. Liquid fuel cutting systems use such fuels as Gasoline (Petrol) Diesel, Kerosene and possibly some aviation fuels.
' bang-gas '), although some authors define knallgas to be a generic term for the mixture of fuel with the precise amount of oxygen required for complete combustion, thus 2:1 oxyhydrogen would be called "hydrogen-knallgas". [3] "Brown's gas" and HHO are terms for oxyhydrogen originating in pseudoscience, although x H 2 + y O 2 is preferred due ...
Diesel engine powerhouse Cummins has begun to shift toward hydrogen fuel cell powertrain development as it aims to become carbon neutral by 2050.
These hydrogen engines burn fuel in the same manner that gasoline engines do. The theoretical maximum power output from a hydrogen engine depends on the air/fuel ratio and fuel injection method used. 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 ...
In 2021, Tokyu Bus reported that the cost of fuelling a hydrogen fuel cell bus is around 2.6 times higher than an equivalent diesel bus, with brown hydrogen predominately used in Japan. [6] In January 2022, the city of Montpellier , France, cancelled a contract to procure 51 buses powered by hydrogen fuel cells, when it found that the cost of ...
