Description

Mechanical inertia intake double-sided turbocharger

technical field

The utility model relates to an air booster device, in particular to a double-sided turbocharger used for air intake of an internal combustion engine.

Background technique

The valves of existing internal combustion engines generally adopt natural suction, the air intake is insufficient, the fuel atomization and combustion are incomplete, and the exhaust gas discharged is seriously polluting. It is of great significance to improve the combustion efficiency of internal combustion engines and reduce the pollution of exhaust gas. The air intake supercharger of internal combustion engine is usually composed of a diffuser tube and an impeller, and is installed in the intake pipe of the engine. The mixing degree helps to improve the combustion efficiency of internal combustion engines and reduce environmental pollution. The outer diameter of the diffuser cylinder of the current supercharger cannot be adjusted, and its versatility is poor. It needs to process a variety of different specifications to meet different types of internal combustion engines; it usually uses an impeller to pressurize, and there is no set on the cylinder wall. There is a flow guide device, so the supercharging effect still needs to be improved, and the vortex effect of the airflow is not obvious; in addition, it needs to maintain a specific direction during installation, which is easy to be installed incorrectly due to negligence, and affect the normal operation of the internal combustion engine.

Contents of the invention

In order to overcome the above technical problems, the utility model provides a mechanical inertial intake double-sided turbocharger with simple structure, convenient installation, strong applicability and good supercharging effect.

In order to achieve the above-mentioned technical purpose, the utility model adopts the following scheme: a mechanical inertia air intake double-sided turbocharger, including an air intake cylinder and two impellers; the two impellers are respectively located at the air inlet and the air outlet of the air intake cylinder, and the two impellers They are respectively fixed at both ends of an impeller shaft, and the impeller shaft is fixed by a bearing device, and the bearing device is fixed in the air intake tube by several supporting ribs; the two ends of the air intake tube are provided with anti-skid bars on the outer wall. Pattern, the variable diameter silicone ring set on the outer wall.

Several spiral guide fins are distributed on the inner wall of the air intake tube.

The utility model has the following beneficial effects: when the airflow passes through the impeller, it drives the impeller to rotate, and when the impeller rotates, the airflow is pressurized and the airflow forms a vortex, thereby increasing the intake air volume and the mixing degree of air and fuel. Because it is equipped with two impellers with the same installation direction, and the inner wall of the air intake tube is provided with spiral guide fins, which can boost the air flow twice and help to improve the vortex effect of the air flow; The thickness of the diameter silicone ring can be processed into various sizes, and the combination of the two can be applied to internal combustion engines of all displacements; because it uses the principle of mechanical inertia to drive the impeller to rotate passively, there is no difference between forward and reverse during installation, and the installation is convenient and quick .
