Problems solved by technology

Therefore, because the engine operates at high rpm in its unloaded state (i.e. when the valves are not actuated), there are several problems, including high noise levels emanating from the engine, Reduced service life of the engine and pump, and higher fuel consumption than consumed at lower rpm

Embodiment Construction

[0020] The subject matter provides an automatic low-idling system and method for small engines. In one aspect, the present subject matter provides a system designed to automatically reduce engine speed below the governed speed range when the engine is under low load conditions (ie, when the pressure washer is not caused to trigger). Specifically, refer to figure 2 , a small engine E may generally include a carburetor C that may be located in the intake passage of the engine E, and the carburetor C may include a throttle control for controlling the delivery of the fuel / air mixture from the carburetor C to the engine E device TC. In one particular embodiment, for example, engine E may be configured to drive a pressure washer system. In particular, the engine may drive a water pump P, which may be connected to a rod W housing a nozzle. A user can actuate a switch or valve S, such as a trigger on a lever W, which can be moved to an "on" position to engage the pump P and start ...

Abstract

The subject matter of the invention relates to the arrangement and use of an engine speed governor. Specifically, an auto-idling system for a small engine may include an engine speed governor coupled to a small engine with a governor shaft rotatable in response to engine speed. A governor linkage may include a first portion for connection to the governor shaft; and a second portion for connection to a throttle controller of the engine, the first portion being movably connected to the The second part is or is movably connected with the second part. An actuator may be connected to the second portion of the governor linkage, the actuator being movable in response to engine load such that the second portion moves relative to the first portion. In this configuration, the second portion is movable relative to the first portion toward a closed throttle position when the engine is under a low load condition.

Description

[0001] priority statement [0002] This application claims the benefit of US Patent Application Serial No. 12 / 500,320, filed July 9, 2009, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The subject matter disclosed herein generally relates to speed regulation systems for small engines. More specifically, the subject matter disclosed herein relates to the deployment and use of engine speed governors. Background technique [0004] Small internal combustion engines can be used in a wide variety of power plants. For example, pressure washers, wood splitters, lawnmowers, air compressors, generators, etc. may use internal combustion engines to power working components (eg, high pressure water pumps, hydraulic pumps, cutting blades). In typical high pressure washers, a speed regulation system may be provided to maintain the engine speed within a governed speed range. refer to figure 1 , a typical speed regulation system may include ...
