Engine synchronizer

A system for synchronizing the rotational speeds of a plurality of engines of a vehicle, the system comprising:

• a master engine and at least one slave engine;
• an actuator assembly connected to said at least one slave engine, said actuator assembly comprising an actuator operably connected to a shaft having an axis and a distal end, said actuator being adapted to displace said shaft along said axis;
• a bracket comprising a first bracket end adapted to operably connect to a throttle cable and an opposing second bracket end attached to said actuator such that said shaft extends generally toward said first bracket end;
• said shaft further comprising a coupling operably connected to said shaft and adapted to connect to throttle plate operably connected to said slave engine such that said displacement of said shaft moves said coupling, thereby moving said throttle plate without substantially moving said bracket;
• a master engine sensor capable of generating a signal corresponding to the rotational speed of said master engine;
• a slave engine sensor capable of generating a signal corresponding to the rotational speed of said at least one slave engine;
• a controller adapted to compare said signal corresponding to the rotational speed of said master engine and said signal corresponding to the rotational speed of said slave engine, and to cause said actuator to adjust said throttle plate of said slave engine to reduce said difference
• whereby the rotational speed of said slave engine is synchronized to the rotational speed of said master engine.

An apparatus for adjusting the speed of an engine, said apparatus comprising:

• an actuator operably connected to a shaft, said actuator being adapted to displace said shaft;
• a first bracket comprising a first bracket end adapted to operably connect to a throttle cable and an opposing second bracket end attached to said shaft;
• a second bracket assembly connected to said actuator and comprising a coupling adapted to connect to a throttle plate such that displacement of said shaft causes said actuator to move, thereby moving said second bracket assembly and said throttle plate without substantially moving said first bracket;
• whereby
• adjustment of said throttle cable moves said first bracket, said shaft and said actuator, thereby causing said coupling to move said throttle plate, and actuation of said actuator causes said actuator to move said coupling.
