  "textContent": "The enhanced two-stroke engine (1) comprises a crankcase (2), a cylinder (3) provided with an exhaust port (6), a series of transfer ports (7) communicating with the crankcase (2), the cylinder (3) further comprises at least an air inlet port (8) positioned in proximity to the exhaust port (6) and connected to a source (13) that supplies pure air towards the port (8), in such a way that the air allowed in by the port (8) creates an air barrier in front of the exhaust port (6); the pollution-abating action is based on three different principles: (i) shield against the egress of cool gases to the exhaust, (ii) oxidation and post-combustion in the exhaust system anticipating the operation of the catalyst, (iii) stratification of the charge of fuel-air mixture in the cylinder with globally leaner combustion with respect to traditional two-stroke engines.",
