Efficient low-energy-consumption four-stroke opposed piston engine

Abstract

The invention discloses an efficient low-energy-consumption four-stroke opposed piston engine which comprises two opposed pistons and air cylinders and a combustion chamber arranged between the two pistons and air cylinders, the two pistons and air cylinders are symmetrically distributed relative to the combustion chamber, an intake valve and an exhaust valve of the combustion chamber are oppositely arranged up and down, the intake valve and the exhaust valve are of a traditional valve structure, the intake valve and the exhaust valve are connected through respective cam transmission mechanisms to achieve alternate opening and closing, and the cam transmission mechanisms are connected with respective pistons and rotating shafts of air cylinders, so that when the pistons move, the intake valve and the exhaust valve can be controlled through the cam transmission mechanisms to be opened and closed in a matched mode to achieve four-stroke air cylinder movement of air suction, compression, acting and air exhaust. The problem that the structure is tedious and swollen due to an external structure of the intake and exhaust valves can be effectively solved, the sealing problem of the intake and exhaust valves can be solved, and the overall performance of the engine can be improved.

Description

Technical field [0001] The present invention relates to the technical field opposed engine, in particular to a low energy efficient four-stroke, opposed-piston engine. Background technique [0002] Boxer engine, piston engine crankshaft evenly distributed on both sides, left and right movement in the horizontal direction. Reduce the overall height of the engine, to shorten the length, the center of gravity of the vehicle decreases, more stable vehicle running, the engine is mounted on the center line of the vehicle, the torque generated by the piston on both sides cancel each other out, greatly reduces vibration of the vehicle traveling in the greatly enhance the engine speed, reduce noise. Good balance piston (180 degrees offset). Compared-line, the balance weight reduction factor required in terms of the crankshaft, to help improve the speed. It can maintain a low speed of 650 rpm, and to ensure a smooth engine operation. Also compared to other types of engine minimum fuel cons...

AI Technical Summary

Problems solved by technology

[0003] However, the current opposed engine, especially the four-stroke opposed engine, uses a sliding sleeve structure for its valve structure, but it will cause a gap due to the impact of the work done by the combustion chamber on the sealing of the sliding sleeve. Due to carbon deposits and other reasons, the valve cannot be completely closed, and the cylinder pressure will also be unequal, which will cause unequal lateral force. In this case, it will also cause left and right vibration
