Chi Sun Lai's latest inventions include an **Electronic Spark Timing Adjustment Circuit** and a **Constant Energy Electronic Ignition System**.
The Electronic Spark Timing Adjustment Circuit provides an electronically adjustable spark timing signal specifically designed for internal combustion engines. This technology operates in conjunction with a breakerless constant percent dwell output electronic ignition system, utilizing a monostable multivibrator circuit that incorporates two constant current sources. These sources produce an electrical signal whose pulse width reflects the desired advance or retardation necessary for optimal engine performance across all speeds. The output signal adapts dynamically as a function of engine speed, ensuring automatic timing adjustments during operation.
The Constant Energy Electronic Ignition System innovates further by coupling a first sensor to the engine to generate ignition-firing pulses, while a second sensor produces multiple pulses in synchronism. These pulses correlate with specified angles of engine rotation and vary inversely to engine RPM. The signals undergo processing through a digital-to-analog converter that outputs a staircase voltage representative of engine position. This sophisticated circuit generates output pulses whose peak amplitude indicates instantaneous engine speed. The resulting trigger signal activates a switch to maintain a consistent ignition coil dwell time, ensuring an optimal energy recharge across varying RPMs.
