Embodiment Construction

[0098] The present invention will be further described below in conjunction with the drawings and embodiments.

[0099] A logarithmic connection hook (39) is provided in the connection part of a spark plug with functional connection and the high-voltage connector, which has an arc-shaped profile of the function connection, which is approximately a section of a logarithmic spiral, in order to obtain Utilizing the characteristic that the pressure angles of the logarithmic spiral are equal everywhere through the logarithmic coupling hook head, a function-connected spark plug and a high-voltage coupling are connected to eliminate the old and difficult problem of accidental ignition and poor contact.

[0100] For engines with logarithmic reed valve port pistons, the spark plug (35) used has a protective welding skin (36) and is wrapped around the discharge electrode (38) to facilitate the discharge electrode (38) and the receiving electrode (35). The component part of the protective sol...

Abstract

The invention relates to a riding lawn mower having a moist filtration muffler. According to the riding lawn mower disclosed by the invention, an adopted engine (27) is provided with a muffler (122) having a plurality of hexagonal pyramid wedges, and a moist filter chamber (123), so that the situation that waste gas firstly enters the muffler having the plurality of the hexagonal pyramid wedges for noise elimination, and then enters a moist filtration layer of the moist filter chamber for noise reduction is facilitated.

Description

Technical field [0001] The invention relates to a riding lawn mower with a wetting filter muffler, belonging to the technical field of pistons, crank connecting rods and spark plugs of internal combustion engines, and an engine-driven lawn mower with logarithmic reed valve port pistons. Background technique [0002] The assembly of piston and crank connecting rod has great potential to be tapped. Seeking improvements in engine pistons, crank connecting rods and spark plugs, as well as lawn mowers driven by engines with logarithmic reed valve port pistons, is an old and difficult problem involving energy saving and emission reduction. Lawn mowers without cameras and rotor blades cannot observe the details of cutting and dicing. Summary of the invention [0003] The technical solutions and methods adopted by the present invention to solve its technical problems are: [0004] The riding lawn mower with a wetting filter muffler adopts an engine with a logarithmic reed valve port pisto...
