It moves.Return solenoid valve 9, which is powered, generates downward electromagnetic force, while oil outlet 12 is opened, and the machine oil inside main piston 6 flows back to oily bottom
In shell, the hydraulic coupling inside main piston 6 reduces, and when 6 inside of main piston, upward hydraulic coupling is less than the downward electricity of return solenoid valve 9
When the spring force resultant force of magnetic force and return spring 10, under downward force action, auxiliary piston 7 is moved downward, and depth pistion subtracts
Small, combustion chamber volume becomes larger, and compression ratio becomes smaller, pressure sensor 17, temperature sensor 18 detect cylinder block 5 inside temperature and
Pressure, when compression ratio is reduced to the value of needs, oil outlet 12 is closed, and return solenoid valve 9 powers off, the power-off knot of self-locking electromagnetic valve 8
It closes, main piston 6 and auxiliary piston 7 are in lockup state, and relative displacement up and down can not occur.
Operating condition 3: when engine is in cold-mix asphalt mixture, 5 inside initial temperature of cylinder block is lower, engine start revolving speed
Lower, the pressure and temperature inside cylinder block 5 is far below normal value, and flammability deteriorates, deterioration of emission, using " variable displacement
And compression ratio " double mode.When main piston 6 is in top dead centre " induction stroke " start time, controller 16 issues instructions to self-locking electricity
Magnet valve 8, return solenoid valve 9 and oil outlet 12, electrically separated on self-locking electromagnetic valve 8, main piston 6 and auxiliary piston 7 are in free state,
Relative displacement up and down can occur.Return solenoid valve 9, which is powered, generates downward electromagnetic force, while oil outlet 12 is opened, main piston 6
Internal machine oil flows back to oil sump, and the hydraulic coupling inside main piston 6 reduces, and when 6 inside of main piston, upward hydraulic coupling is less than downward
Return solenoid valve 9 electromagnetic force and return spring 10 spring force resultant force when, auxiliary piston 7 moves downward, and depth pistion subtracts
Small, cylinder total volume becomes larger, and when increasing to the value of needs, oil outlet 12 is closed, and return solenoid valve 9 powers off, and self-locking electromagnetic valve 8 is disconnected
It is electrically coupled, main piston 6 and auxiliary piston 7 are in lockup state, and relative displacement up and down can not occur.When main piston 6 is past from top dead centre
When lower dead center moves " induction stroke ", since cylinder total volume becomes larger, discharge capacity becomes larger, and cylinder vacuum degree becomes larger, and air inflow increases
It is more.
When main piston 6 is in lower dead center " compression stroke " start time, controller 16 issues instructions to self-locking electromagnetic valve 8, into
Hydraulic fluid port 11.Electrically separated on self-locking electromagnetic valve 8, main piston 6 and auxiliary piston 7 are in free state, and relative displacement up and down can occur.
Oil inlet 11 is opened, and lubricating oil pump 15 pressurizes the machine oil inside oil sump, is entered inside main piston 6 by oil inlet 11, when
When the upward hydraulic coupling in 6 inside of main piston is greater than the downward spring force of return spring 10, it is secondary living that hydraulic coupling overcomes spring force to push
Plug 7 moves upwards, and depth pistion increases, and combustion chamber volume reduces, and compression ratio becomes larger, pressure sensor 17, temperature sensor 18
The temperature and pressure inside cylinder block 5 is detected, when temperature and pressure increases to the value of needs, oil inlet 11 is closed, self-locking electricity
The power-off of magnet valve 8 combines, and main piston 6 and auxiliary piston 7 are in lockup state, and relative displacement up and down can not occur.
Operating condition 4: when engine is in combustion conditions, before pressure sensor 17, the kindling of 18 real-time detection of temperature sensor
Pressure and temperature inside cylinder block 5, if the pressure and temperature inside cylinder block 5 is lower than normal value, " delay period " is long,
Fiery after-combustion pressure and the rate of pressure rise are high, and the impact load that moving parts are subject to is big, and engine operation is rough.Engine enters
" adjusting in real time " mode, controller 16 issue instructions to self-locking electromagnetic valve 8, oil inlet 11.It is electrically separated on self-locking electromagnetic valve 8, it is main
Piston 6 and auxiliary piston 7 are in free state, and relative displacement up and down can occur.Oil inlet 11 is opened, and lubricating oil pump 15 is by cylinder block
Machine oil pressurization inside 5 oil sumps, is entered inside main piston 6 by oil inlet 11, when the upward hydraulic coupling in 6 inside of main piston
