Opposed-piston and opposed-cylinder two-stroke internal combustion engine without connection rod

Abstract

The invention discloses an opposed-piston and opposed-cylinder two-stroke internal combustion engine without a connection rod. The opposed-piston and opposed-cylinder two-stroke internal combustion engine comprises opposed cylinder sleeves, wherein a plurality of opposed pistons are arranged in each cylinder sleeve, and the interior of cylinder sleeve is partitioned into a plurality of cylinders by the opposed pistons; a power output mechanism is arranged on each opposed piston; a synchronization mechanism is arranged on each power output mechanism; a plurality of groups of dual fuel injectorsare symmetrically arranged on each cylinder sleeve; and the power output mechanisms convert the reciprocating rectilinear movement of the opposed pistons in the cylinder sleeves to rotational movement under the constraint of the synchronization mechanisms, so that power output is completed. The opposed-piston and opposed-cylinder two-stroke internal combustion engine disclosed by the invention issimple and reasonable in structure, low in friction loss and high in mechanical efficiency, effectively eliminates a lateral pressure between each piston and the corresponding cylinder sleeve, whichis generated by a crank-connection rod mechanism, and is high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a two-stroke internal combustion engine of a non-connecting rod type with opposed pistons and opposed cylinders. Background technique [0002] The two-stroke internal combustion engine with opposed pistons and opposed cylinders cancels the cylinder head and valve mechanism, and relies on the intake and exhaust ports on the cylinder liner to complete the ventilation in the cylinder. It has the advantages of simple and compact structure, high power density, low cost, light weight, and manufacturing inheritance. Good sex and other advantages. The opposed-piston opposed-cylinder two-stroke internal combustion engine from EcoMotors has two opposed pistons per cylinder. The two pistons are connected to the crankshaft through two connecting rods, one long and one short, and the two cylinders are placed on both sides of the crankshaft, which greatly reduc...

Problems solved by technology

At the same time, the side pressure between the piston and the cylinder liner increases the friction between the two and reduces the mechanical efficiency.

The reciprocating linear motion of the piston assembly and the small end of the connecting rod in the cylinder will generate a reciprocating inertial force, while the circular motion of the crank, crank pin and connecting rod head that deviates from the crankshaft axis will generate a rotational inertial force. Under the joint action of rotational inertial force, the internal combustion engine will produce greater vibration, and at the same time increase the deformation and wear of the internal combustion engine parts; Mechanical efficiency

At the same time, the internal combustion engine with internal and external connecting rods with opposed pistons and opposed cylinders is not conducive to the compact design of the complete engine
