Abstract

A kind of engine for changing internal combustion engine geometrical compression ratio, the adjustment of compression ratio can be completed in a stroke, need only adjust exhaust valve timing, simple, practical, fuel-efficient.

Description

A kind of internal combustion engine for becoming geometrical compression ratio
Technical field
This technology is related to a kind of internal combustion engine for becoming geometrical compression ratio, can adjust compression ratio in a stroke complete.
Background technology
Well known change geometrical compression ratio internal combustion engine is such as：Link-type, gear type, cylinder body offset, hydraulic piston type etc., they Adjustment response performance it is slow, adjustment mechanism is complicated, and weight is big, it is impossible to meet actual needs.
The content of the invention
For reach become geometrical compression ratio transient process adjustment time it is short, the simple real requirement of mechanism.The present invention solves The technical solution of problem is to adjust the exhaust valve closing angle of ZL201420431180.4 patents, and exhaust gas inside cylinder is made to change phase by compression The compression ratio of the compression travel of connection, making the compression travel of engine, instroke is between 2R+2r >=2R in 2R-2r≤2R Variation, so as to the geometrical compression ratio for quickly selecting internal combustion engine reach in any number of 4-30 sections the change of geometrical compression ratio with The simple purpose of the change synchronization of load condition and mechanism.
The invention has the advantages that reducing the specific fuel consumption of Smaller load in internal combustion engine, the adjustment of Ratios need only adjust Closing angle (prior art) mechanism of exhaust valve is simple, and the transient process of adjustment can be completed in a stroke, and response speed is most It is fast practical.
Description of the drawings
Fig. 1 is the mechanism principle figure of the present invention, is operating mode of the internal combustion engine geometrical compression ratio in minimum value 2R-2r ＜ 2R.
Fig. 2 is section operating mode of the geometrical compression ratio in 2R-2r≤2R.
Fig. 3 is operating mode of the geometrical compression ratio in maximum 2R-2r ≈ 2R.

Specific embodiment
Exhaust valve closing angle α degree After Top Center in Fig. 1, geometrical compression ratio
ε=2R-2r ＜ 2R
Exhaust valve closing angle β degree before top dead centre in fig. 2, geometrical compression ratio
ε=2R-2r≤2R
Exhaust valve closing angle γ degree before top dead centre in figure 3, geometrical compression ratio
ε=2R-2r ≈ 2R
General IC Intake Valve Closes angle slightly adjusts preferably.
