Patent ID: 8746191

Claim:
A two-stroke engine comprising: a cylinder having a cylinder bore and defining a cylinder longitudinal axis; a piston mounted in said cylinder to move back and forth therein; said piston delimiting a combustion chamber formed in said cylinder; a crankcase connected to said cylinder; a transfer channel for connecting said crankcase to said combustion chamber at bottom dead center of said piston; an intake channel; an intake arrangement including a carburetor containing a portion of said intake channel; said intake channel dividing into a mixture channel and an air channel; said carburetor including a throttle element mounted therein for controlling the free flow cross section of said intake channel; an intermediate flange connecting said carburetor to said cylinder; said mixture channel and said air channel being guided in said intermediate flange; said intermediate flange having a carburetor connecting surface facing toward said carburetor and a cylinder connecting surface facing toward said cylinder; said air channel bifurcating into first and second branches in said intake channel upstream from said cylinder connecting surface referred to the flow direction in said intake channel; said first and second branches opening with respective air inlet openings at said cylinder bore; said first branch defining a first longitudinal center axis and said second branch defining a second longitudinal center axis; said first longitudinal center axis intersecting said carburetor connecting surface at a first intersect point and said cylinder connecting surface at a second intersect point; said second longitudinal center axis intersecting said carburetor connecting surface at a third intersect point and said cylinder connecting surface at a fourth intersect point; a first connecting line connecting said second intersect point with said fourth intersect point in said cylinder connecting surface; a second connecting line connecting said first intersect point with said third intersect point in said carburetor connecting surface; said first connecting line being projected perpendicularly onto said carburetor connecting surface to define a projected first connecting line; and, said projected first connecting line and said second connecting line conjointly defining an angle (β) greater than 0°.
