Air cleaner of engine and air cleaner mounting device for mounting air cleaner on engine

Abstract

An air cleaner (AC) of an engine, wherein the skirt wall (11a) of an upper cover body (11) near a suction port (50) is extended to the lower side of the suction port (50) to prevent rain drips flowing down the outer surface of a cleaner cover body (10) from being sucked into the air cleaner through the suction port (50). A seal packing (68) and a cleaner element unit (Ue) are stackingly fitted tothe outer periphery of a suction passage (17) in the cleaner cover body (10), and a locking projection (75) tightly engaged with the suction passage (17) is formed on the seal packing (68) to preventthe seal packing (68) from falling down when the cleaner element unit (Ue) is replaced. Furthermore, the air cleaner (AC) is disposed on one side of the engine (E) parallel with each other, the lowerpart of the cleaner cover body (10) is integrally joined to and supported on the engine (E) together with a carburetor (4) with a pair of connection bolts (22, 23). The reinforcement vertical wall part (37) of the cleaner cover body (10) facing the engine (E) through a clearance is integrally joined to and supported on the engine (E) with the other one connection bolt (24). Thus, the supporting rigidity of the air cleaner for supporting the air cleaner on the engine (E) can be increased.

Description

technical field [0001] The present invention relates to an engine, and in particular to an air cleaner that prevents raindrops flowing down the outer surface of a filter cover provided on a general-purpose engine from being sucked in, and prevents the sucked outside air from being sucked into the engine side without being purified, Furthermore, it relates to an air cleaner installation device for installing an air cleaner on an engine for purifying and introducing the outside air into an engine, especially a general-purpose engine. Background technique [0002] Generally, engine-driven working machines are mostly used outdoors, and since the air filter connected to the intake system of the engine is exposed to the atmosphere, the following disadvantages may be incurred: The raindrops flowing down the outer wall of the body are sucked into the air filter by the intake negative pressure of the engine. [0003] Therefore, it is conventionally known to provide an air cleaner wi...

Problems solved by technology

[0011] In addition, in general-purpose engines, the air purified by the air filter is mixed with the fuel in the carburetor supported on the engine, and then the mixed gas is supplied to the engine. The position where the carburetor is away from the engine is supported on the engine in an overhanging state, so there is a problem that it is difficult to ensure the support rigidity of the air filter, and in order to improve the performance of the air filter, the air filter chamber is enlarged In the case of a smaller volume, the air cleaner cover will increase and the above problems will become more significant. Furthermore, in order to fasten the air filter to the engine, sometimes the air filter cover must be removed to install the air filter. Fastened to the engine, which also causes inefficiency in the fastening work of the air filter and the engine
