| Number | Title | Issue Date |
| 5384707 | Diagnostic airflow measurement A diagnostic method for an internal combustion engine determines airflow using three independent airflow determinations. The three airflow determinations are compared to each other and an error is established if one airflow determination differs significa... | 01/24/1995 |
| 5158062 | Adaptive air/fuel ratio control method The rich or lean status of an air/fuel control system is determined according to the difference between the time period that the normalized air/fuel ratio is greater than an upper limit and the time period that the normalized air/fuel ratio is less than a... | 10/27/1992 |
| 5144738 | Automatic retention adjustment of motor armature assembly To adjust axial and radial movement of a thrust plug associated with end play of a rotating shaft, the thrust plug receives the shaft on one side and has a shoulder surface extending from the other side of the thrust plug. A housing position supports a re... | 09/08/1992 |
| 5128583 | Spark plug insulator structure A spark plug is disclosed having a metal body 18, a center electrode 16 and an insulator 14 surrounding the center electrode, the part of the insulator disposed within the combustion chamber being separated by an annular gap from the metal body of the spa... | 07/07/1992 |
| 5089736 | Automatic end play adjustment of motor armature assembly To adjust axial and radial movement of a thrust plug associated with end play of a rotating shaft, the thrust plug receives the shaft on one side and has a shoulder surface extending from the other side of the thrust plug.

| 5083541 | Method and system for controlling engine idle speed An engine idle speed control (ISC) method includes fully opening an idle speed control valve during an engine crank mode and opening the idle speed control valve to a fixed position during a diagnostic mode. The normal idle speed control mode includes sel... | 01/28/1992 |
| 5014676 | Ignition system with repetitive sparks A repetitive spark distributorless ignition system stops ignition current before the complete discharge of magnetic energy in the ignition coil supplying the spark plug. The ignition coil is then recharged so an additional spark can be applied to the spar... | 05/14/1991 |
| 5008824 | Hybrid air charge calculation system A hybrid air charge calculation system for an internal combustion engine in which the air charge is obtained by using either the mass airflow sensor readings or the engine speed and throttle angle information. A decision logic selects either means based o... | 04/16/1991 |
| 5001643 | Adaptive air flow correction for electronic engine control system Air flow determination for an electronically controlled engine includes measuring air flow, determining a correction multiplier, correcting the air flow measurement, and determining if the correction multiplier needs to be updated.... | 03/19/1991 |
| 5000050 | Mass-flow sensor using aerodynamic damping A fluid mass flow sensor uses the effect of aerodynamic drag on a vibrating object.
