Abstract
Combustion charge compositions comprised of a gasoline-like fuel and air for use in spark ignited internal combustion engines and methods to reduce global warming are described.
Claims8
A combustion charge composition for use in spark ignited internal combustion engines with said composition being comprised of a gasoline type fuel and air wherein said fuel contains as part of its specification:
- a. 95 to 100 percent by weight of liquid hydrocarbon volatiles;
- b. an octane number (R+M)/2 range of 70 to 81;
- and
- c. Reid vapor pressure ranges of 6 psi or less (summer) and 6 psi or more (winter) both depending on ambient conditions,
- and wherein said air is ambient air falling within a variable air to fuel weight ratio range of 15:1 to over 30:1.
