Technical Field

The utility model belongs to the technical field of the booster technique and specifically relates to a side booster structure.

Background

The existing methanol engine is developed on the basis of the original diesel engine, and the structure type of the existing methanol engine is a V-shaped engine. The existing methanol engine and an original diesel engine supercharger adopt a mid-set structure, the methanol engine is fixed at the upper end of a flywheel shell, an air outlet of a gas compressor is parallel to the direction of a crankshaft and extends towards the free end of the engine, and a pressurized air pipe is arranged above a V-shaped included angle and is connected and sealed with the air outlet of the gas compressor of the supercharger in a plug connector and O-shaped ring mode. Because the methanol engine is additionally provided with the air inlet manifold cushion block, the air inlet pipes on the two sides move towards the inside of the V-shaped included angle in the opposite direction, the arrangement of the supercharged air pipe is difficult, and the position of the supercharged air pipe is occupied. Under the condition, due to the special structural limitation of the methanol engine, if a supercharger with a middle-mounted structure is adopted, the air outlet of the air compressor only faces upwards and is perpendicular to the direction of the crankshaft, the supercharged air pipe only can be continuously arranged upwards, the height of the whole engine is increased, and the fixation is difficult.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

the utility model provides a side supercharger structure, includes the booster, set up in the inside booster air pipe of engine V type contained angle that is linked together with the booster, the pulse converter that is linked together with the bottom of booster, the left exhaust return bend and the right exhaust return bend that are linked together with the pulse converter, the compressor gas outlet of booster is on a parallel with the bent axle axis, left exhaust return bend and right exhaust return bend pass through support and engine fixed connection.

The utility model discloses technical scheme's further improvement lies in: the direction of extension of the supercharger air pipe is parallel to the axis of the crankshaft.

The utility model discloses technical scheme's further improvement lies in: the V-shaped included angle of the engine is characterized by further comprising an air injection pipe which is arranged inside the V-shaped included angle of the engine and is positioned below an air pipe of the supercharger in an extending direction parallel to the axis of the crankshaft, a plurality of air injection ports are arranged on the air injection pipe, and the air injection pipe is communicated with a compressed air device.

The utility model discloses technical scheme's further improvement lies in: and the opening of the air jet is towards the opening between the supercharger air pipe and the V-shaped included angle.

The utility model discloses technical scheme's further improvement lies in: the air nozzles are positioned on the left side and the right side of the air injection pipe, and the air nozzles on the left side and the right side of the air injection pipe are symmetrically arranged.

The utility model discloses technical scheme's further improvement lies in: the air introduced into the air injection pipe is normal-temperature air.

Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:

the utility model discloses utilize engine V type contained angle spatial arrangement charge air pipe, reduce the complete machine height, the structure is simpler, arranges more rationally, and the installation of being convenient for in time cools down, prevents effectively that equipment is overheated.

The extending direction of the air pipe of the supercharger is parallel to the axis of the crankshaft, so that the air pipe of the supercharger can be conveniently arranged, and the space utilization rate can be improved.

The installation of jet-propelled pipe is convenient for reduce the temperature in the V type contained angle space, is convenient for in time dispel the heat, is convenient for reduce the vibration, effectively utilizes the space, prevents that equipment is overheated. The extension direction of the air injection pipe is parallel to the axis of the crankshaft, so that the air injection pipe and the supercharger air pipe can be synchronously extended and cooled for the supercharger air pipe and each part of the engine. The opening of air jet is towards the opening between booster air pipe and the V type contained angle, prevents that the interior control of air jet from directly jetting on booster air pipe or V type contained angle and causing extra vibration. The air that the jet-propelled pipe inside lets in is normal atmospheric temperature air, prevents that the temperature of blowout air is low excessively, causes the impact that certain part of booster air pipe or engine received too big cooling to cause the material impaired, has prolonged equipment life.
