Product Overview
The TW-G-DHQ is a compact automatic advance ignition module designed for compatible 2-stroke gasoline engines used in small water sports equipment. It adjusts ignition timing according to engine speed, making it suitable for applications where fixed timing cannot respond effectively to rapid changes from idle to high RPM.
With a wide operating range of 800–7,200 RPM, DC 6–14.4V input, and ≥18KV output voltage, the TW-G-DHQ provides speed-related ignition control in a space-saving housing. It can be evaluated for selected personal watercraft, small outboard engines, and powered surfboards.

Why Automatic Ignition Advance Matters for Small Watercraft Engines
Small watercraft engines rarely operate at a constant speed. A typical operating cycle includes:
Starting → Idle → Acceleration → Cruising / Working RPM → Higher RPM
In fixed-timing ignition systems, the ignition point remains predetermined, regardless of engine speed. This can lead to less efficient combustion at certain RPM ranges.
The TW-G-DHQ processes the engine's speed-related trigger signal and adjusts ignition timing according to programmed characteristics. This RPM-based control is especially relevant for 2-stroke engines that must respond quickly to throttle changes.
How the TW-G-DHQ Works
The module operates as part of the engine's ignition system:

Combustion
The engine supplies a speed-dependent trigger signal. The TW-G-DHQ processes that signal and controls the ignition event according to its RPM-based timing curve. As engine speed increases or decreases, the timing is adjusted automatically within the specified operating range.
Note: The exact ignition curve is application-specific and should be matched to the target engine.
Applications
1. Personal Watercraft
Compact Ignition Control for 2-Stroke Watercraft Engines
Personal watercraft have limited space for engine components. The TW-G-DHQ's compact design makes it suitable for evaluation in compatible 2-stroke personal watercraft engines.
Typical related search terms:
personal watercraft ignition module
2-stroke marine ignition
automatic advance ignition system
Compatibility should be confirmed with the engine's trigger signal, ignition coil, supply voltage, and other electrical requirements.
2. Small Outboard Engines
2-Stroke Ignition Module for Lightweight Marine Applications
Small outboard engines must balance power output with size and weight. A compact ignition module is useful when installation space is limited.
The TW-G-DHQ can be evaluated for compatible 2-stroke outboard engines used on small boats and recreational watercraft.
Common search terms include:
2-stroke outboard ignition
outboard ignition module
small outboard ignition module
2-stroke outboard CDI
outboard ignition replacement
For replacement use, always check the original ignition configuration before selecting a new module.
3. Powered Surfboards
Compact Ignition Solution for Small 2-Stroke Engines
Powered surfboards place extreme emphasis on compact packaging. The engine, fuel system, and ignition components must all fit within a very small space.
For suitable 2-stroke gasoline engines, the TW-G-DHQ can be evaluated where automatic ignition advance is required.
Related search terms include:
powered surfboard ignition
motorized surfboard ignition
2-stroke surfboard engine ignition
powered surfboard ignition module
Actual suitability depends on the engine and ignition-system configuration.
Application Summary Table
| Application | Typical Search Terms |
|---|---|
| Personal Watercraft | personal watercraft ignition module, 2-stroke marine ignition |
| Small Outboard Engines | 2-stroke outboard ignition, outboard ignition module |
| Powered Surfboards | powered surfboard ignition, motorized surfboard ignition |
The common requirement across all three applications is a compatible 2-stroke gasoline engine and ignition-system configuration - not the watercraft type itself.
Compatibility Checklist
The TW-G-DHQ supports DC 6–14.4V input and provides an output voltage of ≥18KV. Quiescent power consumption is below 1W, while dynamic power consumption is below 8W.
