Abstract
The utility model protects an intake manifold of a turbo-supercharged engine with a cooling pipe, comprising an intake manifold resonant cavity and an intake manifold airway connected with the resonant cavity. The utility model is characterized in that: a cooling cavity which has a common wall with the intake manifold resonant cavity is arranged under or above the intake manifold resonant cavity; both ends of the cooling cavity are provided with an inlet/outlet communicated with fresh clean air; the designed length of the cooling cavity is more than the length of the resonant cavity so as to obtain the maximum cooling capacity. The utility model has the advantages that: the pipeline designed inside the intake manifold is provided with a cooling pipeline of pressurized gas to further lower the temperature of the compressed gas entering into the intake manifold of an engine, i.e. to lower intake temperature and increase air intake efficiency.
Description
Technical field
The utility model belongs to technical field of automobile engine, is specifically related to adopt petrol engine cold in the exhaust gas turbocharge.
Background technique
At present, adopt cold petrol engine in the exhaust gas turbocharge, because the size of intercooler and the relation of position make through the cooled pressurization gas temperature of intercooler still very high.Too high gas temperature can make gas expand, and causes intake efficiency to descend.
Summary of the invention
The purpose of this utility model is the turbo-supercharged engine intake manifold that proposes to have cooling line, the cooling line of gas after the supercharging is introduced in employing in the pipeline of intake manifold design, further reduce the pressurized gas temperature that enters engine intake manifold, promptly reduce intake temperature, improve intake efficiency.
The technical solution of the utility model is as follows:
A kind of turbo-supercharged engine intake manifold that has cooling line, include the intake manifold resonant cavity with the intake manifold air flue that is connected, it is characterized in that below the intake manifold resonant cavity or above a cooling chamber of wall altogether with it is set, be provided with at the cooling chamber two ends and connect import/export fresh, cleaned air.The design length of this cooling chamber preferably surpasses cavity length, to reach maximum one.
Intake manifold structure of the present invention is compared with existing structure, has following beneficial effect;
1, by the cooling chamber of common wall is set on resonant cavity, reaches utilize fresh cool air to the supercharging that enters resonant cavity after gas cool off, further reduce the pressurized gas temperature that enters engine intake manifold, thereby improve intake efficiency.
2, adopt cooling chamber resonant cavity wall construction altogether, but economical with materials and reduce intake manifold weight also.
3, the clean gas after fresh air filters from empty filter need not be provided with cooling source separately.
Description of drawings
Fig. 1 is resonant cavity and the sectional drawing that is total to the cooling chamber of wall with it;
Fig. 2 is the structural representation of whole engine intake manifold.
Embodiment
Referring to 1 and Fig. 2, in Fig. 1,1 is the intake manifold resonant cavity, 2 is the interlayer between intake manifold resonant cavity and the cooling chamber, 3 is cooling chamber, and 4,5 is the inlet, outlet (according to the position difference that empty filter is arranged, 4 and 5 all can be used as air inlet/outlet) from fresh, the cleaned air of empty filter, 6 is the intake manifold air flue, and 7 is interface.
From Fig. 1 and Fig. 2 as seen, engine intake manifold is along intake manifold resonant cavity 1 lower edge a cooling chamber parallel with it 2 to be set, and this cooling chamber and resonant cavity be wall altogether, and interlayer 3 is promptly arranged, to guarantee the transmission of cooling capacity, the length of cooling chamber 2 surpasses resonant cavity 1 length.Be provided with in addition the inlet, outlet 4 and 5 that is provided with from fresh, the cleaned air of empty filter, interface 7 is arranged on the inlet, outlet 4 and 5 at cooling chamber 2 two ends.
Claims (2)
1. the turbo-supercharged engine intake manifold that has cooling line, include the intake manifold resonant cavity with the intake manifold air flue that is connected, it is characterized in that: below the intake manifold resonant cavity or above a cooling chamber of wall altogether with it is set, be provided with into/air outlet at the cooling chamber two ends.
2. the turbo-supercharged engine intake manifold that has cooling line according to claim 1 is characterized in that: the length of described cooling chamber surpasses cavity length.
