Systems and methods are provided for controlling a power plant during use of a power take-off (PTO) device, wherein the responsiveness and stability of the controller are adjustable by an operator in the field. The use of setting maps allows fine tuning of controller responsiveness while also ensuring that expected performance would be achieved at any setting within the setting map. In some embodiments, a proportional-integral-derivative (PID) controller is used to control engine speed, and gains for the proportional, integral, and derivative terms are obtained from setting maps based on a responsiveness setting chosen by a vehicle operator.

Method of offering finely calibrated engine speed control to a large number of diverse power take-off (PTO) applications

Approaches to control engine overspeed are provided. Engine overspeed is controlled by one or more mechanisms that operate the intake and/or exhaust valves of the engine to interrupt the combustion cycle. In use, the 'combustion interrupter' mechanism(s) actuate the intake and/or exhaust valves according to, for example, one or more control strategies in order to interrupt the combustion cycle and/or cause the engine to expend energy to move the pistons through a complete cycle in an aim to retard engine speed. The engine's cam(s) can include one or more sets of variable valve timing lobes that operate the intake and/or exhaust valves of the engine in order to, for example, interrupt the combustion cycle. The combustion interrupter mechanism can additionally or alternatively include one or more computer controlled actuators that operate the intake and/or exhaust valves in order, for example, to interrupt the combustion cycle.

A flow diffuser for vehicles of the type having an engine and an exhaust pipe generally includes a body including a plurality of inner diffusion ports extending through the body, wherein the body may be attached to an exhaust pipe at or near the exit plane of the exhaust pipe, wherein the body is sized to have a cross-sectional area that is smaller than the cross-sectional area of the exit plane of the exhaust pipe to create a plurality of outer diffusion ports around at least a portion of the outer perimeter of the body when coupled to the exhaust pipe, and one or more extension flaps extending from at least a portion of the outer perimeter of the body.

A fairing assemblyis demountably coupled to a vehicle and includes a first and second support structureandfixedly secured to the vehicle. The fairing assemblyfurther includes a first support memberhaving first end coupled to the first support structureand a second end coupled to the second support structure. A first elastic compression memberis positioned between the first end of the first support memberand the first support structure, and a second elastic compression memberis positioned between the second end of the first support memberand the second support structure. The first and second elastic compression membersimpart opposing forces on the first support memberto position the first support member relative to the first and second support structuresand
