Title:
DOUBLE-PISTON LEVER EFFICIENT ENGINE AND ACTING CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/063202
Kind Code:
A1
Abstract:
Disclosed is a double-piston lever efficient engine, comprising an engine cylinder body (1), wherein a crankshaft (2) is arranged in the engine cylinder body (1), the crankshaft (2) is connected to a body piston (4) by means of a connecting rod (3), a top piston (5) is further arranged in the engine cylinder body (1), and the top piston (5) is driven by a camshaft mechanism. When a power stroke of the engine starts, the body piston (4) is located at a top dead center position, the crankshaft (2) drives the body piston (4) to start to move towards the bottom dead center under the action of inertia, and the camshaft mechanism synchronously starts to accelerate to push the top piston (5) downwards. When the crankshaft (2) reaches a set angle, the top piston (5) is accelerated to be pushed to a near-end position, a closed and narrow compression space is formed between the two pistons, and fuel burns instantly to generate the maximum thrust to push the body piston (4) to move downwards, and the crankshaft (2) synchronously has a certain angle, such that a lever effect is generated, and the maximum thrust is efficiently converted into kinetic energy of rotation to be output.
