Abstract:
1. A method for providing oxygen enriched air to an internal combustion engine of an automobile comprising the steps of: (a) providing a molecular sieve for receiving and expelling air, said sieve having the property (i) of absorbing at least a portion of nitrogen from air moving therethrough under pressure such that air expelled therefrom has a higher concentration of oxygen than atmospheric air and (ii) upon being exposed to atmosphere at normal atmospheric pressure, desorbing at least a portion of said nitrogen; (b) delivering air to and through said molecular sieve under pressure higher than atmospheric pressure to form oxygen enriched air; (c) delivering fuel to said internal combustion engine; (d) delivering said oxygen enriched air and fuel in greater amounts than in step (c) to said internal combustion engine while said automobile is accelerating; (e) stopping step (b); (f) venting said molecular sieve to atmosphere; and (g) delivering normal air and fuel in lesser amounts to said internal combustion engine when said automobile is not accelerating.
