ABSTRACT:
A combustion engine which may be either of the spark-ignition type or the compression-ignition type (Diesel engine) is so constructed that two separate charges having different compositions are injected into a combustion chamber during the intake stroke. The charges are maintained essentially separate, i.e., in stratified condition, during the compression stroke. The combustion process which ensues results in emission of substantially lower quantities of unburnt hydrocarbons, partially-burned hydrocarbons, carbon monoxide and nitrogen oxides than is the case with conventional engines operating either with non-stratified charges or with conventional exhaust gas recirculation systems. One of the charges includes recirculated exhaust gases.
