Internal Combustion Engine Ignition Spark Timing System Modulated By Cylinder Combustion Pressure

View page
US Patent:
41161750, Sep 26, 1978
Filed:
Jul 28, 1976
Appl. No.:
5/709493
Inventors:
Roger D. Sand - Kokomo IN
Assignee:
General Motors Corporation - Detroit MI
International Classification:
F02P 504
US Classification:
123117R
Abstract:
An analog signal of a direct current potential magnitude proportional to the peak combustion pressure of a monitored internal combustion engine cylinder is simultaneously applied to two mutually exclusive comparator circuits, each being arranged to produce a separate respective output signal when the monitored cylinder peak combustion pressure is less than a first predetermined value or greater than a second higher predetermined value. With a signal present upon the output of either comparator circuit, upon the occurrence of a clock signal produced when another selected engine cylinder is later fired, either an ignition spark advance or an ignition spark retard signal is produced as determined by the comparator circuit output signal present. The adjustable ignition spark timing mechanism of an associated ignition distributor is operated to retard the ignition spark in response to an ignition spark retard signal and to advance the ignition spark in response to an ignition spark advance signal. A reset signal produced after the clock signal resets the circuit in preparation for the next firing of the monitored cylinder.

US Patent:
40541118, Oct 18, 1977
Filed:
Jul 19, 1976
Appl. No.:
5/706789
Inventors:
Roger D. Sand - Kokomo IN
Assignee:
General Motors Corporation - Detroit MI
International Classification:
F02P 504
US Classification:
123117D
Abstract:
An encoder produces for each cylinder of an internal combustion engine a plurality of crankshaft position digital code signal groups, each being a representation of a respective different crankshaft position in degrees relative to piston top dead center. A memory circuit responsive to the last output digital code signal group thereof and an excessive cylinder combustion pressure indicating signal, produced when the combustion pressure of a selected engine cylinder exceeds a predetermined value, is preprogrammed to produce, with the presence of the excessive cylinder combustion pressure indicating signal, the digital code signal group representation of the crankshaft position in retard from that as represented by the last output digital code signal group thereof by a preselected number of crankshaft position degrees retard and to produce, in the absence of the excessive cylinder combustion pressure indicating signal, the digital code signal group representation of the crankshaft position in advance of that as represented by the last output digital code signal group thereof by a preselected number of crankshaft position degrees advance. The digital code signal group to which the memory circuit is responsive and the crankshaft position digital code signal groups are compared in a digital comparator which produces an output ignition spark initiating signal when these two signals are equal. Every two crankshaft revolutions, circuitry responsive to a clock signal applies to the input terminals of the comparator an updated digital code signal group and circuitry responsive to a reset signal erases the excessive combustion pressure indicating signal, if present.

US Patent:
41986377, Apr 15, 1980
Filed:
Jul 17, 1978
Appl. No.:
5/925210
Inventors:
Roger D. Sand - Kokomo IN
Assignee:
General Motors Corporation - Detroit MI
International Classification:
H01Q 132
H01Q 110
US Classification:
343715
Abstract:
A vehicle radio antenna control wherein the extension of the antenna is controlled by the radio on-off switch and the vehicle ignition switch in series, and the retraction of the antenna is controlled by a switch which is actuated in response to the manipulation of a mechanism which protects the vehicle from unauthorized entry, such as a door lock, when either or both ignition switch and radio on-off switch are in the off position.
