Abstract
The utility model relates to an engine exhaust pipe with a cooling structure. The engine exhaust pipe comprises a plurality of exhaust pipes and a sealed cooling box body, wherein the exhaust pipes are respectively arranged in the cooling box body, exhaust gas inlets of the exhaust pipes are positioned on the upper end surface of the cooling box body, exhaust gas outlets of the exhaust pipes are positioned on the left end surface of the cooling box body, the exhaust gas outlets of other exhaust pipes are positioned on the right end surface of the cooling box body, and a cooling inlet pipe and a cooling outlet pipe which are communicated with the inside of the cooling box body are arranged on the cooling box body. The engine exhaust pipe can ensure the normal operation and safety of the engine and prevent the heat radiation from damaging other parts of the engine and the high temperature from possibly harming the human body.
Description
Technical field
The utility model relates to a kind of gas outlet means of motor car engine, is specifically related to a kind of engine exhaust pipe with cooling structure.
Background technique
During engine operation, the high-temp waste gas of discharging raises the outlet pipe surface temperature, for the proper functioning and the safety of motor, prevent that thermal radiation infringement other component of motor and high temperature from may cause the injury to human body, motor uses traditional water-cooled exhaust gas pipe mostly.This outlet pipe adopts the cast iron double-layer tube wall structure, and motor adopts isobaric turbosupercharging, and waste gas converges to pressurized machine by an exhaust passage, and cooling water can be taken away the heat that the outlet pipe inwall distributes rapidly and keep the outer tube wall temperature not too high; Pressurized machine utilizes the exhaust gas pressure acting, is using under the water-cooling exhaust pipe condition, and current can be taken away waste-gas heat rapidly, makes exhaust gas pressure decline in the exhaust passage, causes the working efficiency of pressurized machine to descend, and engine performance descends, oil consumption increases thereby make; All waste gases is flowed in the total exhaust passage, and exhaust can appear in each cylinder of motor to be disturbed, and influences the motor scavenging, thereby influences engine performance.
Summary of the invention
At above-mentioned technical problem, the utility model provides a kind of engine exhaust pipe with cooling structure, can not occur exhaust between each cylinder and disturb, can guarantee the proper functioning and the safety of motor, prevent that thermal radiation infringement other component of motor and high temperature from may cause to the human injury.
The realization the technical solution of the utility model is as follows:
A kind of engine exhaust pipe with cooling structure, comprise a plurality of outlet pipes, and the cooling casing of sealing, a plurality of outlet pipes are separately positioned in the cooling casing, the exhaust gas inlet of a plurality of outlet pipes is positioned at the upper-end surface of cooling casing, wherein the exhaust outlet of several outlet pipes is positioned at the left side of cooling casing, the exhaust outlet of remaining several outlet pipes is positioned at the right side of cooling off casing, and the connection that is provided with of described cooling casing is cooled off the cooling inlet pipe of box house, cooled off pipe.
Be provided with temperature detection sensor in the described cooling casing, temperature detection sensor is connected with the controller of cooling system.
The number of described outlet pipe is six, and wherein the exhaust outlet of three outlet pipes is positioned at the left side of cooling casing, the exhaust outlet of three outlet pipes is positioned at the right side of cooling casing in addition.
Adopted such scheme, six cylinders of motor are connected with six outlet pipes respectively, and each cylinder is discharged waste gas by independent outlet pipe like this, have avoided the exhaust between each cylinder to disturb, and do not influence the motor scavenging, and engine performance is brought into play normally; In addition six outlet pipes are arranged in the cooling casing of sealing, can cool off each outlet pipe, in cooling procedure, the real-time chilling temperature in the cooling casing of temperature detection sensor in the cooling casing is monitored, then in the cooling casing, add cooling medium if temperature is too high from the cooling inlet pipe, the utility model can guarantee the proper functioning and the safety of motor, prevent that thermal radiation infringement other component of motor and high temperature from may cause to the human injury.
