A distributor with heat dissipation effect has an ignition device having includes a distributor upper cap, a rotor assembly and a distributor bowl-shaped lower cap, a transmission device connected between the distributor bowl-shaped lower cap and the rotor assembly, and a heat insulation pad held between the distributor bowl-shaped lower cap and the transmission device. When the distributor is assembled on an engine, heat from the engine can be effectively isolated and heat from the ignition device can also be dissipates by the heat insulation pad.

Disclosed is a reluctor plate controller that detects vacuum and pressures in the engine which are used to create digital motor control signals for controlling a reluctor plate actuator using a digital stepper motor, servo motor or a voice-coil actuator. The system can be programmed to create various desired responses that function to create better efficiency of an internal combustion engine, less pollution and/or greater engine output.
