Product Brief Introduction Microprocessor-based digital ignition control module for industrial gas engines, providing precise spark timing and energy management for optimal combustion.
Tag:

Technical Specifications Supply voltage: 18–32 V DC (24 V DC nominal); speed input: magnetic pickup, 100–15,000 Hz; ignition output: 1 channel coil drive, 10 A peak; timing range: 0–60° BTDC; operating temperature: -40 °C to +85 °C; enclosure: IP54; cylinders: up to 8 supported.

Functional Features Programmable spark timing map; speed-based timing advance; dwell control for constant spark energy; start mode timing retard; misfire detection capability; overspeed protection.

Application Scenarios Industrial gas engine ignition control, natural gas and biogas generator sets, stationary engine ignition systems, cogeneration engine control.

Performance Parameters Timing accuracy: ±0.5° crank angle; dwell accuracy: ±2%; misfire detection response: < 2 engine cycles; spark energy consistency: ±5%.

Material Composition Die-cast aluminum housing; microcontroller circuit board; power semiconductor output stage; sealed connector interface.

Structural Characteristics Engine-mountable sealed enclosure; integrated mounting flanges; multi-pin sealed electrical connector; finned heat dissipation profile.

Working Principle Receives engine speed and position signals from a magnetic pickup, references the programmed timing map, and triggers the ignition coil at the precise crank angle, with dwell control to maintain consistent spark energy across engine speed.

Installation Requirements Mount on engine or control panel; connect speed pickup, ignition coil and power wiring; program timing map for specific engine; verify timing with timing light.
