US Patent:

61482587, Nov 14, 2000

Filed:

May 12, 1998

Appl. No.:

9/076291

Inventors:

Mario Boisvert - Reed City MI
David W. Shank - Big Rapids MI
Timothy J. Rigling - Tustin MI
Ronald L. Ballast - McBain MI

Assignee:

Nartron Corporation - Reed City MI

International Classification:

G06F 1900
G06G 770

US Classification:

701 99

Abstract:

An integrated electronic starting control system module for diesel engines which provides unique packaging with integration of a multiplicity of features previously unavailable or available only in separate control modules. Integrated into one modular device are improved glow plug and starting system control, monitoring, protection, and diagnostic features. These features for rendering improved glow plug control and diagnostics include: Microprocessor control, adaptive control algorithms, engine analog temperature sensing for glow plug operational compensation, over temperature shut down protection, system glow plug voltage sensing for glow plug operational compensation, timers for control of glow plug operation and duty cycles, sensing of glow plug current for protective shutdown, control relays and/or solid state switches for control of glow plug current(s), manual override control, load dump voltage spike avoidance circuitry based upon alternator output speed, system monitoring with diagnostics communication capability.

Abstract:

An valve position sensor apparatus for measuring the linear position of an EGR valve including a valve stem portion is disclosed. The apparatus comprises an elongated sensor probe extending from a base and a tubular member slideably overlying a varying length of the probe. The base is adapted to be secured relative to the EGR valve. The probe includes parallel, spaced apart, coextensive primary and secondary windings having a transformer coupling. The tubular member is movable with the EGR valve stem and is comprised of a material adapted to alter the transformer coupling of the overlied windings. An AC signal is supplied to the primary winding thereby inducing a signal in the secondary winding, the magnitude of the induced signal being dependent on the transformer coupling. An output means monitors the signal induced in the secondary winding and provides an output signal related to the linear position of the EGR valve.
