Abstract
The utility model provides a two-channel combined exhaust manifold for an engine, and the two-channel combined exhaust manifold comprises an air outlet main pipe, air inlets connecting the air outlet main pipe with air cylinders, and air outlets connected with a supercharger, wherein the air inlets connected with the air cylinders are independent air inlet pipes, and each independent air inlet pipe is communicated with air outlets. The two air outlets are available, are in parallel with each other, and are separated from each other by a common pipe wall, and the pipe wall is the pipe wall common for the two middle air inlet pipes at the same time, so that the plurality of air inlet pipes are divided into two groups from the middle, and the two groups of air inlet pipes are respectively communicated with the two air outlets. According to the two-channel combined exhaust manifold for the engine, a cylindrical boss of a sensor for measuring the temperature of discharged air is designed at the side-wall regions of the air inlet pipes, and threaded holes for installing the wiring harness of the sensor are machined on the cylindrical boss. The upper side and lower side of each air inlet pipe are respectively provided with the threaded hole connected with the air cylinders. Angles from 45 degrees to 60 degrees are available between a plane A at which the openings of the plurality of independent air inlet pipes are arranged and a plane B at which the air outlets are arranged, so that the air outlets are upwards inclined.
Description
Technical field
The utility model relates to the motor car engine product technical field, specifically a kind of motor Twin channel combination exhaust manifold.
Background technique
Discharge manifold is the pipeline that connects cylinder exhaust port.Generally be that discharge manifold one end is the main air inlet that is connected with the cylinder head air outlet flue, the other end is the total relief opening that is connected with pressurized machine.Prior art can't satisfy pressurized machine and install
Relief opening requirement up can not satisfy that the impact of each temperature difference of the cylinder is little, exhaust is smooth, the requirement of car load coupling.
Summary of the invention
The purpose of this utility model is for the problems referred to above, designs a kind of Twin channel combination exhaust manifold, satisfy relief opening up, the impact of each temperature difference of the cylinder is little, exhaust is smooth requirement.
The technical solution of the utility model: motor double flow channel combination exhaust manifold of the present utility model comprises exhaust manifold and the exhaust manifold suction port that is connected with cylinder and the relief opening that is connected with pressurized machine, its suction port that is connected with each cylinder is suction tude independently, each independently suction tude communicate with relief opening.
Described relief opening has two, and two relief openings are arranged side by side, between separated by the tube wall that shares, the tube wall that two suction tude of this tube wall in the middle of being simultaneously share makes a plurality of independently suction tude be divided into two groups from the centre, two groups of suction tude are communicated with respectively two relief openings.
Described motor double flow channel combination exhaust manifold is designed with cylinder boss be used to the sensor that installs and measures delivery temperature in the sidewall areas of suction tude, is processed with the tapped hole for the sensor installation wire harness on the cylinder boss.
The upper and lower sides of described each suction tude has the bolt hole that is connected with cylinder.
The plane A at described a plurality of independently suction tude mouths of pipe place becomes 45～60 ° of angles with the plane B at relief opening place, and relief opening is inclined upwardly.
