Problems solved by technology

Therefore, for different types of engines, it is necessary to design one speed control mechanism for horizontal left-right direction actuation and another different speed control mechanism for vertical up-down direction actuation, which forces an increase in cost, total number of parts and Inventory increase

Embodiment Construction

[0027] Referring to Figures 1a-2b, there is shown a small internal combustion engine 10 which includes a speed control mechanism according to the present invention.

[0028] Engine 10 may be a small internal combustion engine of the type produced by Tecumseh Power Company of Grafton, Wisconsin, and includes known components not visible in the drawings, including the crankcase and connection to the crankshaft A cylinder block on the case that includes one or more bores for receiving pistons. Each piston is connected with a crankshaft of engine 10 via a connecting rod. The engine 10 shown here is a horizontal crankshaft engine; however, the invention is equally applicable to vertical crankshaft engines. Some typical motors that may be used with the speed control mechanism of the present invention as will be described below are disclosed in U.S. Patent No. 6,295,959, No. 6,612,275 and No. 6,941,914, each of which is assigned to the assignee of the present invention , the conten...

Abstract

A common engine speed control mechanism for small internal combustion engines, which may be configured to allow for actuation of the speed control mechanism between stop, idle, and various engine running speed positions by actuation of one of a selected plurality of speed control levers. Each of the plurality of speed control levers is oriented so that it is movable in a direction which is substantially non-parallel to the direction of movement of the other speed control levers. In one embodiment, the actuation of the common speed control mechanism can be accomplished by movement of a first speed control lever in a substantially horizontal, side-to-side direction or by movement of a second speed control lever in a substantially vertical, up-and-down direction.

Description

technical field [0001] This invention relates to small internal combustion engines used in lawn mowers, lawn tractors, other utility tools, and sporting vehicles, and more particularly to speed control mechanisms for these engines. Background technique [0002] Small internal combustion engines typically include a carburetor that provides one or more combustion chambers of the engine with an air / fuel mixture for combustion to drive the engine's pistons and crankshaft. Engine speed is usually regulated by a throttle valve mounted in the intake passage of the carburetor, which is movable between a fully closed position and a fully open position, wherein the fully closed position corresponds to the engine being stopped or the engine running at a low speed Or idling, the fully open position corresponds to the engine running at its operating speed. [0003] Many small internal combustion engines also include a governor for maintaining the engine's desired operating speed, which ...
