Title:
LOW EMISSIONS TWO-CYCLE INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO2000070211
Kind Code:
B1
Abstract:
A two-cycle engine comprises a cylinder block (37) containing two parallel cylinders (45, 61) adjacent to each other. One cylinder (61) operating as a volumetric fuel pump. Both cylinders' center lines lying in a plane perpendicular to a crankshaft (34). The cylinder block (37) is disposed over an engine block (32) having a crankcase (31). The two pistons (40, 59) are connected by a connecting rod (38) to a common crankpin (35). The kinematics of this engine leads to advancing the pump piston (59) ahead of the power piston (40). The combustion gases are evacuated by air compressed into the crankcase (31) through scavenging ports (65). After the exhaust port closes (41), a rich air/fuel mixture is introduced into the power cylinder (45) through a unidirectional valve (48).
