Description
Technical field
The present invention relates to a kind of different angle regulating devices of engine.It is different more particularly to a kind of engine with index dial
Angle adjusts experimental rig.
Background technique
For engine, tumble flow exists simultaneously the tissue of more conducively combustion process with vortex.But four-valve engine by
It is arranged in twin-inlet symmetrical configuration and drives two cam profiles of inlet valve almost consistent, two inlet valves are in same a period of time
It is the same to carve opening degree, so that two inlet valve intake velocities of synchronization and air inflow are identical, is revolved in cylinder body cross-sectional direction
Turn air-flow to cancel out each other, the mass motion of air shows as single longitudinal tumble flow mode in cylinder, there's almost no vortex, this is
Cause mixed Daqu it is bad, deteriorate burning a key factor.Vortex meeting is such as obtained using tangential air flue or rotation air flue
Keep cylinder cover structure complicated, gas-flow resistance increases.When an inlet valve open, another IC Intake Valve Closes can produce compared with maelstrom (Wang Jian,
Liu Dexin, Liu Shuliang etc., current stabilization experimental study [J] internal combustion engine journal of four-air valve petrol engine inlet duct flow dynamic characteristic, 2004,
22(2):182-186)；Using slidingtype variable air inflow structure, in inlet manifold valve is respectively set also and can generate vortex, control
(Liu Ruilin, Liu Zengyong, Gao Jin wait vortex characteristic examination in the cylinder of four-air valve petrol engine Variable inclined swirl system generation to system vortex
Test research [J] internal-combustion engine engineering, 2006,27 (3): 29-32；Li Ming, Liu Dexin, Yang Yanxiang gasoline engine variable vortex air inlet pipe
Influence [J] combustion science and technology to vortex characteristic in cylinder, 2009,4:146-150), but it is equivalent to reduction or cut through
Divide inlet channel, affects air inflow.Lift range variable technology also can produce vortex, control vortex (king to a certain extent
Its friend, Liu great Ming, under Zhang Xueen lift range variable in Engine gas flow characteristic research [J] internal combustion engine journal,
2008,26 (5): 420-428；The such as Zhao Changpu, Zhong Bo, Zhu Yunyao lift range variable is to turbocharging direct spray petrol engine in cylinder
Influence [J] the University Of Tianjin journal (natural science and engineering technology version) of In-Cylinder Flow characteristic, 2013,46 (8): 737-742).
But these structures either two admission cam lifts become smaller simultaneously or one of admission cam lift becomes smaller, obtain compared with
Strong vortex is equivalent to part and closes two valves or in which a valve, but make in this way negotiability than double inlet valves (or into
Air flue) standard-sized sheet is poor, and obtaining high vortex intensity is to sacrifice charge flow rate as cost.
In order to solve the above problem, a kind of dress of different lift of engine variable inlet valve for not reducing charge flow rate is devised
Set obtain vortex (Zhang Shiqiang, Liu Ruilin, Liu Wuquan wait the device patent of invention of the different lift of engine variable inlet valve:
ZL201310029510.7,2015.2 authorizations), the device for the different lift of verifying engine variable inlet valve generates large scale eddy
The effect of stream has invented the different angle regulation experiment device of the different lift of corresponding engine variable inlet valve (Liu Ruilin, scholar
By force, Liu Wuquan waits the different angle regulation experiment device patent of invention of the different lift of engine variable inlet valve:
ZL201310265094.0,2016.01 authorizations), started on intake channel steady flow analogue testing stand using the above experimental provision
When machine in-cylinder air motion characteristic test, find when the different angle regulation experiment device obtains camshaft degree numerical value very not
Just, corner accuracy is also poor.
