Abstract:
A method of starting an engine includes the steps of starting a fuel supply pump, opening a fuel solenoid to allow fuel flow to a combustor to at least partially begin, and beginning to operate a starter motor to drive a shaft associated with the engine. Then an ignitor is excited to spark in the combustor. An engine is also disclosed.
Abstract:
A filter includes an outlet from a container, the outlet transverse to said inlet and a filter screen within the container that partially surrounds the outlet. In a further embodiment of the foregoing embodiment, the filter screen prevents passage of particles greater in size than 40 to 6000 microns. In a further embodiment of any of the foregoing embodiments, the filter screen provides a pressure drop of less than 0.5 psi. In a further embodiment of any of the foregoing embodiments, the filter screen defines a tortuous path with a bypass there around. In a further embodiment of any of the foregoing embodiments, the filter screen is cylindrical and extends parallel to a length of said container.
