Description
🧾 PRODUCT OVERVIEW
The Hyundai H420G is a 420cc petrol engine with gear reduction, designed for applications requiring lower output speed and higher torque.
The “G” variant indicates:
👉 Integrated reduction gearbox
👉 Output shaft rotates at reduced RPM
👉 Significantly increased torque at output
Based on the proven Hyundai 420cc platform (~15HP), this engine is ideal for heavy-duty equipment where controlled speed and power delivery are critical.
⚙️ KEY FEATURES
- ⚙️ Gear reduction system (G variant) – high torque output
- ⛽ 420cc 4-stroke OHV engine – reliable performance
- 🔧 Horizontal shaft configuration
- 🛢️ 6.5L fuel tank (typical) – extended runtime
- 🛡️ Oil alert system – protects engine from damage
- 🏗️ Heavy-duty industrial construction
