摘要： A control methodology and apparatus for an engine suitable for use in capacitor discharge ignition systems for internal combustion engines or brushless DC motors is provided, which make use of a simple logic block to determine for instance an ignition timing advance angle or duty cycle signal based on actual engine speed versus engine control parameter data stored in a table, which is a read-only memory, preferably configurable. To minimize memory space, a small number of values of engine control parameter versus engine speed are stored in the table and the logic block determines the required engine control signal for a measured value of engine speed by an interpolation process, preferably linear interpolation.

摘要： An ignition control device having an Electronic Fuel Injection mode and a Capacitive Discharge ignition mode is described. The ignition control device comprises: an output for providing an output voltage, connected or connectable to a load, the load being a fuel injection actuator of an EFI system or an ignition capacitor of a CDI system; and a driver unit connected to the output, for driving the output voltage from a low level to a high level and from the high level to the low level in dependence on an input signal, each transition of the output voltage from the low level to the high level having a low-to-high transition time which is longer for the CDI mode than for the EFI mode.
