Abstract

An air intake device includes a supercharger, a connection tube, an intercooler, and an intake manifold. The supercharger is connected to an exhaust port of a cylinder. The intercooler is connected to the supercharger through the connection tube. The intake manifold is connected to the intercooler and an intake port of the cylinder. The intercooler is located above a cylinder head of an engine. The device of the present disclosure features less height space occupation, a short connection tubeline between elements and a compact structure, which is beneficial for an increase of the pressurization response speed and reduction in the cost.

First claim

What is claimed is:

1. An air intake device comprising:
a supercharger connected to an exhaust port of a cylinder;
a connection tube;
an intercooler connected to the supercharger through the connection tube, and
an intake manifold connected to the intercooler and an air inlet of the cylinder,
wherein the intercooler is located above a cylinder head of an engine;
wherein the intake manifold is disposed above the cylinder head of the engine;
wherein the air intake device is of a flat structure;
wherein a gas passage in the intercooler is inclined downward relative to a horizontal direction, and a height of a gas passage inlet of the intercooler is higher than a height of a gas passage outlet;
wherein the supercharger is located on an upper left side of the cylinder head of the engine;
wherein an exhaust gas inlet pipe of the supercharger is connected to an exhaust gas inlet of the supercharger and extends upward from the exhaust gas inlet; and
wherein a height of the exhaust gas inlet pipe between the exhaust gas inlet and a turbine is greater than a height of the exhaust gas inlet.

2. The air intake device according to claim 1 , wherein a height of an air outlet of the supercharger is lower than the height of the gas passage inlet of the intercooler.

3. The air intake device according to claim 1 , wherein the gas passage of the intercooler is inclined downward relative to the horizontal direction at an angle ranging from 13.65° to 19.65°.

4. The air intake device according to claim 1 , wherein an intake passage in the intake manifold is inclined downward relative to a horizontal direction, and a height of one end of the intake passage close to the intercooler is higher than a height of one end of the intake passage close to the cylinder.

5. The air intake device according to claim 4 , wherein the intake passage in the intake manifold is inclined downward relative to the horizontal direction.

6. The air intake device according to claim 5 , wherein the intake passage in the intake manifold is inclined downward relative to the horizontal direction at an angle ranging from 22° to 28°.

7. The air intake device according to claim 4 , wherein the intake manifold further comprises a pressure stabilizing chamber having a height higher than a height of the intake passage.

8. The air intake device according to claim 1 , further comprising a throttle valve directly fixed between the intercooler and the intake manifold.

9. The air intake device according to claim 8 , wherein the throttle valve is of a flat structure.

10. The air intake device according to claim 1 , wherein the connection tube has a V-shaped structure with an apex pointing upwards.
