Prevent coolant liquid from carrying out supercooling to block temperature, and keep current desirable temperature range, at this time can it is appropriate will
The aperture of solenoid valve controls in lower range, so that distributing the coolant rate to block jacket from cylinder head jacket
It is smaller, it is only necessary to the heat constantly generated in cylinder block to be offset, so that cylinder block maintains current temperature.
(c4) when first object section be normal interval when, and the second target interval be the second high temperature section when, keep electricity
The aperture of magnet valve is to default moderate range.
Wherein, the corresponding opening value of above-mentioned default moderate range is greater than the corresponding opening value of above-mentioned default minuent range.
When to determine current cylinder temperature moderate in desirable temperature range for controller, and coolant temperature is higher, examine
It is poor to consider current coolant liquid cooling effect, it, can be appropriate by solenoid valve in order to keep current desirable temperature range
Aperture controls in the range of moderate, so that moderate, the gas that distributes the coolant rate to block jacket from cylinder head jacket
Cylinder body maintains current temperature.
(c5) when first object section is the first high temperature section, increase the aperture of solenoid valve to preset height range.
Wherein, the corresponding opening value of above-mentioned preset height range is greater than the corresponding opening value of above-mentioned default moderate range.Its
In the default low range, default moderate range and preset height range, can be determined according to priori, or according to more
Secondary test determines, is not limited thereto.
When controller determines current cylinder temperature higher (being greater than desirable temperature range), no matter liquid temperature is in any area
Between, it is required to pay the utmost attention to cool down to cylinder block, increases the aperture of solenoid valve to preset height range, so that from cylinder head jacket
It distributes to the coolant rate in block jacket and increases, to cylinder block fast cooling, avoid scuffing of cylinder bore and caused by components
Damage, while improving fuel efficiency.
In conclusion controlling in coolant liquid cyclic process the circulation path of cylinder block coolant liquid, realize to gas
The switch and flow of lateral between cylinder body water jacket and cylinder head jacket adjust.
