Two-stroke gasoline engine with functions of auxiliarily simulating aerodynamic analysis and adding double-filter-screen scavenging

Abstract

The invention provides a continuously improved and perfected two-stroke gasoline engine with the functions of auxiliarily simulating the aerodynamic analysis and adding double-filter-screen scavenging. According to the two-stroke gasoline engine, a double-screen-cloth and a scavenging opening buffering valve are added in a scavenging channel, and the emission reduction function and the standard reaching effect are achieved. A filter screen (58) in the scavenging channel is arranged beside a technological lap piece (55) and below the scavenging channel. The filter screen in the scavenging channel is formed by weaving a plurality of metal wires in a longitudinal and latitudinal mode and has the filtering function. The filter screen, namely, the screen cloth and the scavenging opening buffering valve, arranged below the scavenging channel and the double-screen-cloth, namely, the filter screen all have the regulating effect on air in a cylinder and breathe among crankcases. A plurality of wedges arranged on an anti-noise filter screen are provided, and then a catalytic roll is provided. The catalytic roll contains platinum, rhodium, indium and iridium and has the catalytic effect, so that airflow noise and hydrocarbon compounds (HC) emission are skillfully relieved. It is a new technology to apply the blade aerodynamic noise analysis simulated through computer digitals to a garden machine. The method for auxiliarily simulating the aerodynamic noise analysis can be conducted through LMS Virtual lab software, and learning and using are easy.

Description

technical field [0001] The invention provides a shrub cutter belt mower used for cutting shrubs in places such as flower beds, gardens, parks, roads, etc., in the shape of flowers and trees, belonging to the field of garden machines. Using the innovative method of indirect discharge after passing through the 1.5-meter catalase muffler pipe, in order to expand the use, a mowing head with cutting stacks and mowing steel wires, a cutting disc with internal and external serrations and carburetor are installed on the brush cutter The four-pronged nozzle of the device, and the long grass pressing wheel for easy grass pressing and moisture retention and grass pattern, to form a low-emission gasoline brush cutter. Combustion chamber with function wave and matching with ignition device for internal combustion engine with movable receiving electrode and micro-moving discharging electrode, double auxiliary skirt on piston skirt to reduce hydrocarbon emission, and logarithmic differential...
