Title:
INTERNAL COMBUSTION ENGINE HAVING VARIABLE VOLUME COMBUSTION CHAMBER AND AUXILIARY PISTON
Document Type and Number:
WIPO Patent Application WO/2016/150231
Kind Code:
A1
Abstract:
An internal combustion engine having a variable volume combustion chamber and an auxiliary piston. The internal combustion engine comprises a cylinder (21), a piston (22), and a crankshaft connected in a transmission manner by a connecting rod (23). A position on a cylinder head (2) and close to a side of the cylinder is provided with a small cylinder (26) constituting a combustion chamber volume, and the controlled auxiliary piston (31) is mounted within the small cylinder. When a compression process is completed within the cylinder (21), the auxiliary piston (31) within a small cylinder combustion chamber is also driven to move to a position forming a maximum combustion chamber volume, and after the cylinder (21) has begun a work-doing process, the auxiliary piston rapidly presses work-doing gas produced within the small cylinder combustion chamber into the cylinder to push the piston (22) to do work, causing a clearance volume formed between the small cylinder (26) and the cylinder (21) to be in a minimal state, so that the work-doing gas which originally expanded in the combustion chamber is pressed into the cylinder to expand and do work, thereby further increasing the efficiency of the internal combustion engine.
