An Ultrasonic Intake Port for Gasoline Engine

Abstract

The invention discloses an ultrasonic-wave gas inlet passage for a gasoline engine. The ultrasonic-wave gas inlet passage comprises a gas passage connected with the gasoline engine and a carburetor or electronic control fuel injection system arranged in the gas passage. A cavity with an opening is formed in the narrow position between the downstream of a fuel oil injection port of the carburetor or electronic control fuel injection system in the gas passage and a gas inlet of the gasoline engine, and the opening of the cavity faces inlet gas flow. According to the ultrasonic-wave gas inlet passage, the cavity is formed in the ultrasonic-wave gas inlet passage, when the inlet gas flow of the gasoline engine passes through the gas passage, the opening of the cavity is impacted at the high speed, sound waves even ultrasonic waves are generated in the cavity, the sound waves (ultrasonic waves) are transmitted and reflected inside communication components such as the gas passage and the gasoline engine, fuel oil atomization and fuel oil vaporization are promoted, mixing and burning of the fuel oil and air are strengthened, lean burning and supplemental burning of the gasoline engine are facilitated, the air-fuel ratio is improved, the burning temperature is reduced, harmful waste gas discharging is reduced, the design compression ratio is improved, the efficiency of an engine under the partial loads is improved, energy conservation and environment protection are achieved, starting is easily achieved, and the maximum power is improved.

Description

technical field [0001] The invention relates to an ultrasonic air inlet for a gasoline engine. Background technique [0002] Existing gasoline engines, fuel-air mixing devices (carburetors or electronically controlled fuel injection systems, etc.) have poor atomization of fuel, and there are a large number of large-diameter oil droplets at the outlet that are not conducive to full combustion. Its air intake channel does not use fluid mechanics to optimize the structure of the airflow movement mode. The fuel mist and air basically flow in a synchronous laminar flow, and the relative speed is very low, which makes it impossible to further atomize and vaporize the fuel. Therefore, the combustion of the existing gasoline engine is difficult to be sufficient, and the content of carbon monoxide and hydrocarbons in the exhaust gas is relatively high. Moreover, due to poor intake air atomization and vaporized fuel, existing gasoline engines can only operate within a relatively narr...
