Start up system for hydrogen generator used with an internal combustion engine [PDF]

open access: yes, 1977
A hydrogen generator provides hydrogen rich product gases which are mixed with the fuel being supplied to an internal combustion engine for the purpose of enabling a very lean mixture of that fuel to be used, whereby nitrous oxides emitted by the engine ...

Modeling of NO sensitization of IC engines surrogate fuels auto-ignition and combustion [PDF]

open access: yesarXiv, 2009
This paper presents a new chemical kinetic model developed for the simulation of auto-ignition and combustion of engine surrogate fuel mixtures sensitized by the presence of NOx. The chemical mechanism is based on the PRF auto-ignition model (n-heptane/iso-octane) of Buda et al. [1] and the NO/n-butane/n-pentane model of Glaude et al. [2].
