Title:
DIRECTLY-CONNECTED PISTON ENGINE WITH NO CRANKSHAFT
Document Type and Number:
WIPO Patent Application WO/2019/052186
Kind Code:
A1
Abstract:
A directly-connected piston engine with no crankshaft comprises a cylinder group (1), a piston group (2), a connecting mechanism (3), and a first flywheel (4). The cylinder group (1) comprises a horizontally opposed first cylinder (11) and second cylinder (12). The piston group (2) comprises a first piston (21) and a second piston (22) respectively disposed in the first cylinder (11) and the second cylinder (12). The connecting mechanism (3) is connected to the first flywheel (4), and comprises a connecting rod (5), a first rotating shaft (31), a second rotating shaft (32), and an output shaft (33). The engine also comprises a second flywheel (9). The cylinder group (1) and the piston group (2) each comprise a second group having the same structure as the first group. The two groups of pistons move in opposite directions, are connected to the second flywheel (9) by the same connecting mechanism and are connected to an engine gearbox by a common shaft (10). Reciprocating motion of the pistons directly works via interaction of the connecting rods, energy loss is low, and efficiency is high. Moreover, a connection point of the connecting mechanism has low friction and low resistance. The two groups of cylinders and pistons cancel out the reaction force generated by energy combustion, reducing engine vibrations and ensuring engine stability.
