Engine air cleaner

#This disclosure relates in general to an engine air cleaner for the intake of an internal combustion engine, and more specifically an engine air cleaner including multiple tubes for dividing the flow of air for the intake of the internal combustion engine from debris.

#An internal combustion engine includes one or more cylinders that receive a flow through an intake manifold. The flow may be a mixture of air and fuel or only air. The intake manifold may include a carburetor and/or an air filter. In some environments, debris may enter the intake manifold. Debris may include dirt particles, or grass, for example. The intake manifold may be connected to a cleaner or separator for removing the debris from the flow of air.

#Exemplary implementations are described herein with reference to the following drawings.

#FIG. 1A illustrates an example three-dimensional view of an air cleaner for an engine.

#FIG. 1B illustrates an example two dimensional view of the air cleaner.

#FIGS. 1A-1D illustrate an example air cleaner 100 for removing debris from the intake of an engine. FIG. 1A illustrates a three dimensional view of the air cleaner 100, FIG. 1B illustrates a two dimensional view of the air cleaner 100, FIG. 1C illustrates an exploded front view of the components of the air cleaner 100, and FIG. 1D illustrates an exploded rear view of the components of the air cleaner 100. FIG. 1E illustrates an engine 101 including the air cleaner 101 of FIGS. 1A-1D.

#The air cleaner 100 includes a housing 13, an air filter fastener 15, a mounting grip 16, an air filter 17, a flow tube 10, and an air cleaner 100 outlet 21 for the engine intake or a combustion air manifold that is indirectly coupled with the set of flow tubes 10. The air cleaner 100 may also include additional outlets such as but not limited to a debris outlet and an air outlet. The flow tube 10 may include an inner tube 11, an outer tube 12, and a static actuator or air vane 14. The air cleaner 100 may also include multiple cavities including an output air cavity 25, a dirt ejection cavity 18, an air ejection cavity (not illustrated in FIG. 1), and an air injection cavity 23. Additional, different, or fewer components may be included.

#The air cleaner housing 13 surrounds the components of the air cleaner 100 and secures the air cleaner 100 to the engine. In one example, an air cleaner base 35 (illustrated in FIGS. 1C and 1D) is coupled to the carburetor, throttle body, or intake manifold. The air cleaner housing 13 and optionally flow tubes 10 and filter 17 are amounted to the air cleaner base 35.
