Embodiment Construction

[0022] People in this industry know that the compression ratio is the ratio of the volume of the cylinder above the top of the piston (called the combustion chamber) when the piston is at the top dead center to the volume of the cylinder above the top of the piston (called the total working volume) when the piston is at the bottom dead center. Reducing the volume of the combustion chamber increases the compression ratio. Our test prototype uses a 168F engine with a piston diameter of 68mm, a stroke of 45mm, and a displacement of 163ml. The original 1.2mm thick cylinder gasket is changed to a 0.2mm thick cylinder gasket, so that the volume of the combustion chamber is reduced from 21.6ml to 18ml Left and right, the compression ratio is increased to 10; the spray pipe is designed with 3 rows on the back of the air intake direction (one row in the middle, and one row of small holes with a diameter of 0.3mm at 30° intervals on both sides. In order to ensure the effect of atomizatio...

Abstract

The invention relates to a high-compression-ratio carburetor type gasoline engine. The compression ratio can be improved from normal 8.5 to 10-12, the defects of poor atomization and poor mixing of a normal carburetor are solved by mainly utilizing an injection spray pipe installed in a carburetor throat, the problem that knocking is generated after the compression ratio is improved is solved, and compared with the original engine, the gasoline engine provided by the invention has the advantages of larger power, lower energy consumption and better emission.

Description

Technical field: [0001] The invention relates to a high compression ratio carburetor gasoline engine. Background technique: [0002] With the further shortage of oil and energy in the world, European and American countries have higher and higher requirements for waste emissions. my country has also formulated the National III standard for two-wheeled and three-wheeled motorcycles that is equal to foreign standards, and also for non-road general-purpose engines. Emission regulations equivalent to those in Europe and the United States have been formulated. my country is a major producer of motorcycles, and the annual output of non-road general-purpose engines exceeds 17 million units, but most of the products do not meet the requirements of the above emission regulations. Whether to strictly enforce the established regulations is a serious issue before law enforcement agencies and relevant personnel in this industry. [0003] Existing small gasoline engines for non-road use a...
