A lawn mower includes an internal combustion engine (112), an electric motor (120) configured to start the engine (112), a blade driven by the engine aBST(112), and an assembly for stopping at least one of the blade and the engine. The assembly includes a brake mechanism (514), a release mechanism (126) movable to an engaged position to release the brake mechanism (514), an interlock (128) configured to selectively prevent the release mechanism (126) from moving to the engaged position, and an interface (122) allowing an operator to release the interlock (128) to allow the release mechanism (126) to move to the engaged position. The lawn mower further includes a switch (432) actuated by the release mechanism (126) and a control module (430) coupled to the switch (432) so that the switch provides a signal to the control module (430) when the release mechanism (126) is in the engaged position and the control module (430) turns on the electric motor (120) in response to the signal to start the engine (112).

An internal combustion engine (1000) includes an engine block (1002) including a cylinder (1004); a piston (1006) positioned within the cylinder (1004); a crankshaft (1008) configured to be driven by the piston (1006); a fuel system (1001) for supplying an air-fuel mixture to the cylinder (1004); a starter motor (1014); and a lithium-ion battery (1020) mounted on the engine, the lithium-ion battery (1020) configured to power the starter motor (1014) to start the engine (1000).
摘要:
A carburettor (10; 310) includes a body (14; 314), a throttle valve (26; 326) positioned in an air/fuel passageway (18; 318) in the body, a fuel bowl (30; 330) coupled to the body, a fuel bowl chamber (34; 334) at least partially defined by the fuel bowl, and a one-piece fuel-metering insert (42; 342) coupled to the body. The insert includes an idle circuit passageway (62; 362) having a first end in fluid communication with a fuel passageway in the body and a second end in fluid communication with the fuel bowl chamber (34; 334). The insert also includes a main circuit passageway (66; 366) having a first end in fluid communication with the air/fuel passageway (18; 318) and a second end in fluid communication with the fuel bowl chamber (34; 334).
摘要:
An internal combustion engine includes an engine block including a cylinder, a piston positioned within the cylinder, wherein the piston is configured to reciprocate in the cylinder along a cylinder axis, a crankshaft configured to be driven by the piston, a fuel system for supplying an air-fuel mixture to the cylinder, and an electric starting system including a starter motor, a battery receiver, and a lithium-ion battery removably attached to the battery receiver, wherein the lithium-ion battery is configured to power the starter motor to start the engine, wherein the lithium-ion battery includes at least one lithium-ion cell having a cell axis, and wherein the battery receiver is positioned so that with the lithium-ion battery attached to the battery receiver, the cylinder axis and the cell axis are not parallel to one another.
