Problems solved by technology

In this way, the working stroke is longer, the working energy is consumed, and the energy conversion efficiency is greatly reduced.
Therefore, most of the existing vehicle engines are heat engines with low energy conversion, and the energy conversion efficiency cannot be further improved, so that the energy of each drop of oil cannot be fully utilized.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] refer to figure 1 , the variable power stroke engine crank-link mechanism of the present invention comprises a crankshaft 10 and at least one connecting rod 13 that is rotatably connected to its journal 11 at one end, the journal 11 is provided with a crank distance changing mechanism, and the connecting rod 13 is provided with There is a control mechanism for controlling the change of the curvature, and the journal 11 is also provided with a control mechanism for controlling the change of the curvature. The eccentric sleeve 15 is controlled jointly by the control tooth 12 and the control tooth 14, so that it can achieve the purpose of changing the stroke distance of the engine.

[0018] refer to figure 2 and image 3 , the control mechanism includes: a control tooth 12 provided on the journal 11 and a control tooth 14 provided on the connect...

Abstract

The invention discloses an engine crank-connecting rod mechanism with a variable expansion stroke, which comprises a crankshaft and at least one connecting rod of which one end forms rotatable connection with the shaft neck of the crankshaft, wherein the shaft neck of the crankshaft is provided with a crank moment change mechanism and a control mechanism for controlling the change of the crank moment; and a hole which is connected with the connecting rod is also provided with a control mechanism for controlling the crank moment change. The engine crank-connecting rod mechanism can improve the energy conversion efficiency by automatically shortening the distance of the expansion stroke, and the power stroke is shortened to ensure that the heat transfer is quicker, and the thrust of fuel production is more powerful so as to improve the engine efficiency. Because the energy conversion efficiency is improved and the power loss is reduced, the economy of the fuel is achieved.

Description

technical field [0001] The invention relates to an engine, in particular to a crank connecting rod mechanism of a reciprocating piston engine. Background technique [0002] On the existing vehicle engine, the motion distance of the air intake, compression stroke, work and exhaust stroke of the engine is the same, and the air intake capacity and the work capacity are also the same. In this way, the working stroke is longer, the working energy is consumed, and the conversion efficiency of energy is greatly reduced. Therefore, most of the existing vehicle engines are heat engines with low energy conversion, which cannot further improve the energy conversion efficiency, thereby failing to fully utilize the energy of each drop of oil. Obviously, if the stroke of the engine is variable, the energy conversion efficiency can be improved by automatically shortening the distance of the power stroke. The shortening of the power stroke makes the heat transfer faster, the thrust generat...
