Embodiment Construction

[0006] (4) The exhaust valve needle is used as the only top of the (1) combustion chamber and (5) the exhaust pipe part is completely sealed to form the combustion chamber. When the piston (2) is compressed, (4) the exhaust valve needle moves upward to a certain position, its upper limit is determined by (10) pump piston, (13) variable lift and stop lever and (14) EPU signal. At this time, the combustion chamber is only composed of (5) exhaust pipe and (4) exhaust valve needle In that section (combustion chamber size, extensibility, and lower edge can be customized according to needs), during the exhaust stroke, the valve mechanism makes the exhaust valve fully open when the piston is at the bottom dead center according to the movement process of the piston. (4) The exhaust valve needle uses the negative pressure generated by the spring to take the exhaust gas out of the combustion chamber, and at the same time absorbs fresh air. The inertial spring flips back and forth for ene...

Abstract

The improved-type internal combustion engine combustor is made up of exhausting valve needle; a part of exhaust pipe; variable lift stop bar; offset friction upper link rod and inertial spring. It has advantage of adjustable internal space of combustion room and capable of discharging empty of waste gas. It is adapted to using in internal combustion engine system.

Description

1. Technical field [0001] The present invention relates to internal combustion engines, in particular to the improvement of combustion systems of internal combustion engines. 2. Technical Background [0002] There are many types of internal combustion engine combustion chambers in the prior art, including bathtub type, hemispherical, etc. There are various types, each with its own advantages and disadvantages. The main disadvantage is that the exhaust gas cannot be completely removed and the combustion effect is not good. In addition to gas exchange, the intake and exhaust valves have low utilization. Overall efficiency is not high. 3. Contents of the invention [0003] The purpose of the present invention is mainly to solve the problems of dirty exhaust gas discharge and low combustion efficiency of the four-stroke internal combustion engine in the prior art, in order to improve the efficiency of the internal combustion engine. The basic idea of ​​the present invention ...
