A104 (CDI) TCI Electronic Ignition System

TCI Transistorized Electronic Ignition | Hall Ignition Angle Compatible with DLE...... | Low EMI | High Reliability | Military-Grade Potting Protection | R&D and Manufactured in Taiwan (Non-China Supply Chain) | UAV / Drone Power Systems

A Next-Generation Electronic Ignition System Built for High-Reliability Gasoline Engines

Hsinhua EDOS proudly introduces the A104 (CDI) TCI Transistorized Electronic Ignition System. Built around high-reliability electronic ignition technology, it is specifically designed for model aircraft engines, UAV/drone gasoline power systems, and high-RPM small gasoline engines.

Unlike traditional capacitive discharge ignition (CDI) systems, TCI utilizes a different control architecture. It directly sources ignition energy from the battery supply and manages ignition timing electronically. This makes it ideal for

 applications demanding low EMI, high reliability, extended operation, and flight controller stability.

Utilizes Taiwan-Patented Separated High-Voltage Ignition Coils for Single/Twin Cylinders

Taiwan Patent No.: Taiwan M669038

• Exclusive Separated Design: Effectively reduces electromagnetic interference and enhances safety.

• Engineered for Single/Twin Cylinder Engines: Optimizes ignition efficiency and stability.

Core Advantages

• Taiwan R&D & Manufacturing: Non-China supply chain.

• DLE Compatible: Hall ignition angle is identical to DLE.

• High Reliability:

  • Stable Ignition Energy for Extended Operation: TCI does not rely on instantaneous discharge from a capacitor like CDI. It delivers a longer spark duration, resulting in more complete combustion, stable idling, and improved low-to-mid-range torque. (Automotive and motorcycle EFI systems all utilize TCI).

  • Extended Spark Duration: Ensures reliable ignition even at low RPMs.

  • Direct Battery Power: Unlike traditional architectures that rely on engine RPM to build up high-voltage charging energy, TCI delivers precise ignition control during low-RPM startup.

  • High Temperature Resistance & Long Lifespan: Designed for long-duration cruise missions.

• Low EMI Design: Features a low-EMI circuit architecture to suppress large high-frequency charging pulses typical of traditional CDI systems, ensuring maximum stability for flight controllers, GPS, and onboard systems.

• Smart RPM Ignition Control: Adjusts spark advance timing in real time according to engine RPM to optimize combustion efficiency. Adjustable spark intensity.

• Military-Grade Components + Fully Potted Protection: Engine igniters for UAVs and model aircraft operate under severe conditions including high vibration, extreme heat, moisture, dust, salt spray, and EMI. The military-grade components and fully potted enclosure dramatically increase resistance to moisture, dust, salt corrosion, and vibration.

Applications

• UAV / Drones: Tailored for UAV gasoline engines and long-endurance power systems requiring low EMI, high reliability, and long-running times.

• High-RPM Small Gasoline Engines: Ideal for compact, high-speed gasoline engines.

• Specialized Flight Platforms: Serves as a reliable ignition solution for specialized platforms requiring low-EMI operating environments.
