Possibly one of the most significant advantages that hydrogen may have as a fuel is its potential for increased second … hydrocarbon-based fuels. A computational investigation of this effect is pursued for the case of mixtures of hydrogen and natural … function of hydrogen content of the fuel and the operating parameters of the engine. Of particular importance is the …

Hydrogen-fueled internal combustion engines are considered to be more efficient and cleaner alternatives to their …, control and optimization of hydrogen engines. To serve for this broader purpose, a computational model, which has been widely … used for gasoline and diesel engines, is investigated for its capability to simulate hydrogen engines. Specifically, fuel …

This paper experimentally investigated the co-effect of cylinder cutoff and hydrogen addition … engine equipped with an electronically controlled hydrogen injection system and a hybrid electronic control unit. The engine …, respectively. For each cylinder closing strategy, the hydrogen energy fraction in the total fuel (βH2) was increased from 0% to …

The membrane reactor is a novel technology for the production of hydrogen from natural gas. It promises economic small …-scale hydrogen production, e.g. at refuelling stations and has the potential of inexpensive CO2 separation. Four configurations of … to assess the trade-off between production scale and the construction of a hydrogen and a CO2 distribution infrastructure …
