INJECTION SYSTEM FOR TWO-STROKE ENGINES

摘要

An electronic injection two-stroke endothermic engine comprising an upper fuel injector (13) and a lower fuel injector (14), both accommodated in an intake duct (12) directly facing the cylinder (1), the latter closed by a head to form a combustion chamber (6) with one or more spark plugs (5) and connected to a pump-crankcase underneath via a plurality of side transfer ports (7, 8) which a central transfer port (15) is added to and crosses said intake duct (12) and allows the fuel sprayed by said lower injector (14) to reach the inside of the cylinder (1).
