ABSTRACT:
High-compression spark-ignited stratified-charge fuel-injection reciprocating-piston engine in which the combustion chamber initial charge includes a discrete air-fuel stratum that is lean with fuel at low speed idle and progressively increased in fuel richness and volume until that stratum ultimately completely fills the chamber with a homogeneous air-fuel mixture using all of the intaken air to attain maximum power. The combustion process minimizes pollutive exhaust emissions.
