Lean combustion in automotive engines: as assessment of the addition of hydrogen to gasoline as compared to other techniques
An examination was made of the feasibility, practicability, performance, fuel economy, and emissions of the concept of the addition of hydrogen to gasoline for use as an automobile fuel. The specific hydrogen addition concepts evaluated included onboard storage of hydrogen as a bottled gas, as a cryogenic liquid, and as a regenerable gas in a metal hydride storage system, and the onboard generation of hydrogen by the reformation of gasoline in a fuel reformer (or gas generator). Both partial oxidation and steam reforming fuel reformers were considered. For perspective, comparisons were made of the hydrogen addition concept with the conventional spark ignition engine baseline and other lean engine concepts, e.g., advanced lean carbureted engines and stratified charge engines. Hydrogen addition via fuel reformation was found to be a feasible method of achieving ultralean engine operation.
