    摘要: An electronic engine control monitors engine speed, vehicle speed and determines various engine RPM values and RPM ranges used in fueling a molar vehicle engine to achieve desired engine speeds prior to and during an automatic gear shift sequence. The engine is coupled to a manual/automatic transmission that includes manually selectable gear operation modes and automatically selectable gear operation modes. In order to assist gear engagement of the automatically selectable gears, the engine is fueled to a series of predetermined RPM levels to rock the transmission gears into engagement. In so doing, throttle control by the operator is first inhibited and the engine is first governed to a synchronous RPM value. Throttle control is returned to the operator if gear engagement is verified within a first predetermined delay period. If gear engagement is not verified, the engine RPM is periodically increased or decreased, depending on whether an upshift or downshift is attempted, and throttle control is returned to the operator if gear engagement is verified within a second or third predetermined delay period. If gear engagement is still not verified, the engine RPM is returned to the synchronous RPM value for a fourth predetermined delay period. If gear engagement does not occur within the fourth delay period, an error recovery routine is executed.

    摘要: A system for controlling ignition energy of an internal combustion engine includes an ignition coil having a primary coil and a secondary coil coupled to first and second electrodes of an ignition plug defining a spark gap therebetween, wherein the primary coil is operable to induce a spark voltage across the secondary coil and across the spark gap. The secondary coil is responsive to the spark voltage to produce a discharge current across the spark gap of the ignition plug. In accordance with one aspect of the invention, means are provided for controllably shunting the primary coil to thereby control the duration of discharge current across the spark gap of the ignition plug. In accordance with another aspect of the present invention, means are further provided for drawing discharge current away from the ignition plug to thereby limit the magnitude of the discharge current within some time period after the transfer of energy from the primary coil to the secondary coil begins. The principles of the present invention are accordingly applicable to control the duration and/or magnitude of ignition plug discharge current to thereby minimize electrode erosion while maximizing ignitability in either a conventional ignition plug-based ignition system or an arc propelling ignition plug-based ignition system.
