Description
Technical field
The utility model relates to a kind of intake manifold, especially relates to a kind of plastic air intake manifold of the integrated water-cooled intercooler in throttle body front end.
Background technique
At present, turbosupercharged engine relies on turbosupercharger to carry out greater engine air inflow thus obtains the motor of higher moment of torsion and power; Because turbosupercharger is that the gas of discharging by motor drives, need to cool air inlet so can be raised by the intake temperature after pressurized machine.Conventional cooling means has two kinds of i.e. directly coolings and indirectly cooling.
So-called directly cooling is exactly that participation gas and gas carry out heat exchange to carry out heat trnasfer, be about to the radiator that the gas after pressurized machine is incorporated into automotive front end, the air inlet gas higher to the temperature after supercharging by radiator carries out wind-cooling heat dissipating cooling, cooled gas is incorporated into throttle body by pressure pipeline, and then by intake manifold, gas is assigned in each cylinder body of motor.
So-called cooling indirectly refer to the medium participating in cooling be through air-cooled after the medium such as cooling water, be about to be introduced directly into throttle body through the high-temperature gas of pressurized machine through pressure pipeline and enter into intake manifold, gas is cooled by the water-cooled intercooler being integrated in plastic air intake manifold, first high-temperature gas carries out cooling by water-cooling cooler to air inlet gas in intake manifold, is redistributed to each air flue of intake manifold thus is transported in each cylinder body of motor.
When employing directly cools, because the gas after supercharging needs could arrive in cylinder through longer pipeline path, make pressurized machine from start to final arrival and need the regular hour in cylinder and the phenomenons such as accelerated reaction is slow that cause supercharged engine to occur, and occupy more engine compartment arrangement space and be unfavorable for the shortcomings such as the minimizing of energy-absorbing safe distance after the layout of engine compartment miscellaneous part and car crash.
Adopt when indirectly cooling, because the high temperature air inlet gas after supercharging is introduced directly into throttle body, cause throttle body temperature too high and damage internal sensor and electronic unit thus motor cannot normally be worked shortcomings such as bringing potential safety hazard; This method is owing to directly entering in engine cylinder-body by intake manifold air flue by the gas after water-cooled intercooler, and effectively cannot utilize the maximum cooling effectiveness of intercooler, cause due to through the region of water-cooling cooler with area is inconsistent and to enter the gas temperature of each cylinder body after causing cooling inconsistent, thus affect the power of motor and the dangerous working conditions such as engine combustion pinking even appear in moment of torsion.

The intake manifold of integrated intercooler is utilized to reduce installing space.The intake manifold that make use of integrated intercooler greatly reduces the temperature entering throttle body, avoids the damage to throttle body electronic component.Owing to first passing through throttle body by the gas after intercooler, enter intake manifold air flue more then in engine cylinder-body, the maximum cooling effectiveness of intercooler can be made full use of, thus ensure that the uniformity consistency of the air inlet gas temperature through throttle body, thus improve the power of motor and moment of torsion and avoid occurring the dangerous working conditions such as engine combustion pinking.
Compared with prior art, the utility model has the following advantages:
One, throttle body is solved overheated: because the high-temperature gas after pressurized machine is first through supercooler, then cooled gas is again by throttle body, solves the throttle body body temperature of throttle body caused by high-temperature gas and raises and cause internal sensor to damage and affect the problem of traffic safety.
Two, the conformity of intake temperature is ensured: because gas temperature is even after intercooler cooling, greatly can improve engine performance, reduce CO2 emission.
Three, airtight performance is good: the seal ring available protecting manifold its Surrounding Parts that intercooler place installs is from the infringement of hot air.
Four, the flexibility of application: above the remodeling that can be applied to present supercharged engine flexibly and upgrading, solve the obstacle of electronic parts and components that motor runs in upgrading.
Five, manufacture stability high: due to intake manifold fluctuating plate be all be molding and forming after, employing vibration friction welding connect, so increase substantially for the manufacture stability of product, reduce reject ratio.
Six, energy-saving and emission-reduction: integrated design has shortened engine charge path, reduce the pressure loss of gas, improve the booster response of motor and decrease the weight using and reduce motor itself of material, finally decreasing oil consumption and the discharge of automobile.
