Abstract: A safety system for engine powered machinery having a fuel cut functionality to promote more rapid shutdown of the rotating parts of the engine powered machinery. In one aspect, the system is implemented as a wiring harness disposed exclusively on the engine which simultaneously disables one or more ignition coils and prevents a fuel-air mixer from supplying a mixture of air and fuel to the engine upon activation of a safety switch. In alternate aspects, the system further comprises a stator brake which is activated by the safety switch to provide additional braking torque on the engine. These features bring the machinery to a rapid halt, further enhancing safety.

Abstract: A method for manufacturing engine powered machinery having a fuel cut functionality to promote more rapid shutdown of the rotating parts of the engine powered machinery. In one aspect, the method is implemented by assembling a wiring harness disposed exclusively on the engine which are configured to simultaneously disable one or more ignition coils and prevent a fuel-air mixer from supplying a mixture of air and fuel to the engine upon activation of a safety switch. In alternate aspects, the method further comprises a stator brake which is activated by the safety switch to provide additional braking torque on the engine. These features bring the machinery to a rapid halt, further enhancing safety.

Abstract translation: 用于发动机动力机械的安全系统具有燃料切断功能，以促进发动机动力机械的旋转部件的更快速关闭。 在一个方面，该系统被实现为专门设置在发动机上的线束，其同时禁用一个或多个点火线圈并且在启动安全开关时防止燃料 - 空气混合器将空气和燃料的混合物供应到发动机。 在替代方面，系统还包括定子制动器，该定子制动器由安全开关启动以在发动机上提供额外的制动转矩。 这些功能使机器迅速停止，进一步提高安全性。
