Title:
METHOD FOR IMPROVING EFFECTIVE THERMAL EFFICIENCY OF ENGINE AND POWER TRANSMISSION MECHANISM PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2019/192288
Kind Code:
A1
Abstract:
A method for improving the effective thermal efficiency of an engine and a power transmission mechanism prepared thereby, said mechanism comprising a cylinder (1); a piston (2) is mounted in the cylinder (1), the piston (2) is connected to crank links (4, 13) by means of a connector, the crank links (4, 13) are respectively connected to cranks (7, 10) by means of crank shafts (6, 11), the cranks (7, 10) are connected to bent axles (8, 9), there are two bent axles (8, 9), and an eccentric distance (e) is set, and the eccentric distance is the distance between a bent axle axis and an axis of a connecting end between a piston rod and the crank link, the connecting end between the piston rod and the crank link is located above the bent axle center point, or the eccentric distance is the distance between the bent axle axis and the axis of the connecting end between a pin shaft on a circular slide block and the crank link, or the eccentric distance is the distance between the bent axle axis and the axis of the connecting end between the piston and the crank link, and the eccentric distance (e) is greater than the crank radius (R), the range of the angle through which the crank rotates is less than 180 degrees during working stroke. By this way, the overall mechanism is compact; when the bent axles rotate in a negative bias manner, the bent axles splash lubricating oil always toward the piston, the piston cylinder is well lubricated, the engine oil has strong heat dissipation effect for the piston, and the engine has high working strength and long service life.
