Detachable supercharger of single-cylinder internal combustion engine

Abstract

The invention relates to a detachable single-cylinder combustion engine pressurizing device, which is formed by an air compressor, a flywheel of combustion engine, a bracket, a spring and a drawing rod. Wherein, the friction wheel of air compressor is connected to the flywheel via friction drive; the air compressor is movably connected to the bracket via axle sleeve; the spring is mounted between the bracket and the air compressor to process friction drive between friction wheel and the flywheel, to confirm the normal operation of blade wheel of air compressor; and a drawing rod is connected to the support, drawing which the friction wheel and the flywheel can be separated. The invention with simple structure can apply the pressurizing demands in different rotational speed of single cylinder machine to improve power, reduce dirt discharge and save fuel.

Description

technical field [0001] The invention relates to the technical field of supercharging of internal combustion engines, in particular to the technical field of supercharging of single-cylinder internal combustion engines. Background technique [0002] In internal combustion engine supercharging technology, there are turbocharging technology and mechanical supercharging technology. The power source used in turbocharging technology comes from the exhaust gas of the internal combustion engine. The technology cannot be applied to single-cylinder internal combustion engines. In Chinese Patent No. 96207809.3, "Single Cylinder Series Diesel Engine Supercharging Device", the power source for supercharging comes from the flywheel on the power output shaft of the internal combustion engine, and the impeller shaft of the turbocharger is connected to the flywheel of the internal combustion engine by means of belt or gear transmission. The patent claims that the tra...

AI Technical Summary

Problems solved by technology

The supercharging purpose to be achieved by this patent cannot be realized. First, the speed of the supercharger can only be moved at a relatively low speed by using a belt drive, and it is impossible to reach 30,000 revolutions. This is because the existing The diameter of the flywheel of the single-cylinder machine is about 500mm. To achieve a transmission ratio of 1:15, the diameter of the pulley of the supercharger is only about 30mm. The diameter of the pulley of the supercharger is too small, and there is no wrap angle. unreasonable

Second, the described situation of adopting the gear transmission mode is carried out without any lubrication and in a harsh environment, which is not allowed for the gear transmission structure. In summary, the implementation of this patent is difficult Yes, the effect is not obvious

[0003] In the application of the current mechanical supercharging technology, a belt transmission mode with a low transmission ratio is adopted between the power output shaft of the internal combustion engine and the supercharger to increase the torque of the internal combustion engine at low speed. This transmission mode increases with the speed of the internal combustion engine. However, it has no adjustment function itself, and the speed of the supercharger cannot adapt to the supercharging requirements of the internal combustion engine at different speeds, and the fuel-saving effect is not obvious.
