HYDROGEN-ENRICHMENT-CONCEPT PRELIMINARY EVALUATION FINAL REPORT

摘要

The Jet Propulsion Laboratory (JPL) has previously investigated the feasibility of supplementing automotive engine gasoline/air mixtures with a hydro¬gen rich gas in order to permit the combustion of gasoline under ultralean condi¬tions. It is desirable to operate an automobile engine in the ultralean region because the thermal efficiency is increased and the peak combustion tempera¬tures are decreased. Increased engine thermal efficiency leads directly to improved fuel economy, while lower combustion temperatures result in lessnNO formation. xnThe JPL concept for producing the hydrogen avoids the hazard of carrying stored quantities of the gas in the automobile by generating the desired amount on a demand basis. This is accomplished by using a hydrogen generator in conjunction with a standard IC engine.
