Wetting the appetite of spark ignition engines for lean combustion. SAE Paper 780234

摘要: Single-cylinder spark ignition engine experiments conducted at constant speed, fixed airflow, and using isooctane as the fuel, demonstrated effects of fuel-air mixture preparation on lean operation. Mixture was changed by varying time fuel injection in induction manifold, near intake valve port. For comparison, a prevaporized also investigated. Emphasis placed determining combustion characteristics. Based results from this study, often favored air may not be best diet for
