Abstract
A device capable of changing distance between an automobile engine air inlet to the ground comprises a normal condition air inlet pipe 1, a wading condition air inlet pipe 2, an air inlet pipe switching valve control device 3, an air inlet pipe switching valve 4 and an air filter 5, and is characterized in that the distance between an air inlet of the wading condition air inlet pipe 2 to the ground is dozens of centimeters longer than the distance between an air inlet of the normal condition air inlet pipe 1 to the ground; a driver can select the air inlet of an engine by operating the air inlet pipe switching valve control device 3 and the air inlet pipe switching valve 4 according to road conditions; when an automobile runs in a normal road condition, the air inlet pipe switching valve control device 3 is in a non-working state, air enters from the normal condition air inlet pipe 1, then passes through the air filter 5 and then flows into an engine cylinder, when the automobile wades to run, the air inlet pipe switching valve control device 3 is opened, and the air entering from the wading condition air inlet pipe 2 flows into the engine cylinder after passing through the air filter 5, so that the possibility that water enters the engine cylinder during wading driving of the automobile can be greatly reduced, and a favorable condition is provided for wading driving of the automobile.
Description
Technical field
The present invention relates to the Automobile Motor Design field, be specially a kind of car engine air admittance mouth road clearance variset.
Background technique
China's Urbanization Construction development in recent years is very fast, but, quite a few city its urban infrastructure standard for various reasons is on the low side, meet thunderstorm rain severse weather or continuous several days heavy showers weather, waterlogging often occurs in urban road, and the urban road waterlogging has brought great inconvenience to people's trip, and the people that especially open car trip are subject to great impact especially, motor car engine is flame-out, and automobile is sat of common occurrence.We know, can automobile paddle to travel smoothly has certain relation with car engine air admittance mouth road clearance, in case because if car engine air admittance mouth water inlet, motor is just immediately flame-out, if starting by force, you will cause at once that motor is badly damaged, so people wish this moment the engine intake road clearance is uprised paddling while driving, to reduce the possibility of engine intake water inlet.Yet the present more consideration of motor car engine is compact structure and power energy-saving etc., and the specific (special) requirements while for automobile wading, travelling is often considered seldom, so car engine air admittance mouth road clearance is all changeless now, if people drive to go on a journey and meet road waterlogging ponding and must paddle while moving ahead like this, it is unique that what can do is meticulous, drive with caution, way is available nothing better.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of suction port road clearance variset that is applied on motor car engine, this car engine air admittance mouth road clearance variset can be in automobile running way as road waterlogging ponding and must paddle while passing through, can suitably improve car engine air admittance mouth road clearance, thereby paddle smoothly and move ahead for automobile, avoid engine misses to create favorable conditions.
in order to achieve the above object, the technical solution used in the present invention is: a kind of car engine air admittance mouth road clearance variset, this application of installation is on automobile, this device comprises the normal conditions suction tude, the condition of paddling suction tude, suction tude switching valve control gear, suction tude switching valve and air-strainer, it is characterized in that: the condition of paddling suction tude suction port road clearance is higher tens centimetres than normal conditions suction tude suction port road clearance, when automobile travels under normal operation, suction tude switching valve control gear is not worked, this moment normal conditions suction tude and air-strainer conducting, the condition of paddling suction tude and air-strainer path are cut off, air enters by in air-strainer flow direction engine cylinder from normal conditions suction tude suction port, in case meet road waterlogging ponding, automobile need be paddled while passing through, the driver opens suction tude switching valve control gear, this moment, normal conditions suction tude and air-strainer path were cut off, the condition of paddling suction tude and air-strainer conducting, air enters by in air-strainer flow direction engine cylinder from the condition suction tude suction port of paddling.
During concrete enforcement, the driver looks the road actual conditions and determines to open or close described automobile engine intake tube switching valve control gear.
Owing to having taked above-mentioned technological scheme, a present invention compared with prior art obvious advantage is: when described automobile runs into road surface waterlogging ponding in the process of moving, as long as open described automobile engine intake tube switching valve control gear, this moment, described engine charge was provided by the condition suction tude of paddling, and the described condition suction tude of paddling exceeds tens centimetres due to its road clearance than described normal conditions suction tude road clearance, so greatly reduced the possibility of described engine charge water inlet tube, thereby for automobile, paddle smoothly to travel, provided safeguard.

Embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 2, the car engine air admittance mouth road clearance variset in the present embodiment comprise normal conditions suction tude 1, the condition of paddling suction tude 2, suction tude switching valve control gear 3, suction tude switching valve 4 and air-strainer 5.
When described automobile travels under normal road conditions condition at ordinary times, suction tude switching valve control gear 3 in described car engine air admittance mouth road clearance variset is in off position, at this moment, normal conditions suction tude 1 and air-strainer 5 conductings, the condition of paddling suction tude 2 is cut off by suction tude switching valve 4 with air-strainer 5 paths, and the air inlet of described motor car engine enters in cylinder after air-strainer 5 from normal conditions suction tude 1.(seeing accompanying drawing 1)
Described automobile is when waterlogging ponding road traveling, the driver opens described automobile engine intake tube switching valve control gear 3,4 actions of suction tude switching valve, at this moment, normal conditions suction tude 1 is cut off by suction tude switching valve 4 with air-strainer 5 paths, the condition of paddling suction tude 2 and air-strainer 5 conductings, the air inlet of described motor car engine enters in cylinder after air-strainer 5 from the condition suction tude 2 of paddling.(seeing accompanying drawing 2)
Suction tude switching valve control gear 3 can be used manual control mode, also can, with solenoid valve or other control modes such as pneumatic, can select as the case may be.
The above embodiment has only expressed the specific embodiment of the present invention; therefore but can not be interpreted as it is restriction to scope of patent protection of the present invention; should be noted that; for a person skilled in the art; without departing from the inventive concept of the premise; can also make certain adjustments and improvements structural type of the present invention, these all belong to protection scope of the present invention.
