The Air-cool 30CC Engine SSL-30 from fourobot conveys 3.8HP at 8500rpm with accuracy designing. This single-cylinder powerhouse weighs fair 1320g whereas creating an noteworthy 8.5kg drag constrain at 100m elevation. Supported by 10 a long time of fabricating ability and certified to worldwide measures (CE, ISO, TAF, TELEC), our engine highlights a demonstrated 7.6:1 compression proportion and dependable air-cooling innovation. With 100 units in stock and a quick 20-day generation cycle, you get enterprise-grade execution without the wait.

You require hardware that works when you do. Our SSL-30 understands your greatest challenge: keeping apparatus cool without including weight or complexity.
Traditional liquid-cooled frameworks come up short you in inaccessible areas. They spill. They include bulk. They require consistent maintenance.
Our air-cooling plan changes everything. Outside cooling balances scatter warm normally. No radiators. No pumps. No coolant worries.
The 30cm³ uprooting conveys reliable control over requesting applications. Whether you're working rambles at tall height or running generators in hot climates, this Air-cool 30CC Engine maintains performance.
Key determinations you can check on:
Altitude influences control, but we've designed arrangements. At ocean level, you get 8.5kg drag constrain. Indeed at 1800m rise, execution remains solid at 7.5kg.
The 30:1 grease proportion optimizes security without carbon buildup. Our accuracy designing guarantees proficient fuel combustion over changing temperatures.
This engine powers your most critical equipment:
Agricultural UAVs: Your spray drones need lightweight endurance. Our engine delivers 20-minute flight cycles in humid conditions without overheating.
Industrial Robotics: Survey rovers demand high torque at low speeds. The air-cooled design prevents heat buildup in dusty construction sites.
Landscaping Equipment: Commercial pole saws and blowers run 8+ hours daily. Our engine maintains power even when ambient temperatures exceed 40°C.
RC Applications: Hobbyists and professionals trust our reliability for high-performance remote-controlled vehicles.

Q: What fuel mixture should I use?
A: Use a 30:1 fuel-to-oil ratio. Always select high-quality synthetic oil rated JASO FD to prevent carbon deposits on cooling fins.
Q: How do I maintain optimal cooling in hot environments?
A: Keep cooling fins clean and unobstructed. Inspect regularly for debris buildup that restricts airflow. Ensure proper ventilation around the engine during operation.
Q: What's the expected service life before major maintenance?
A: With proper maintenance schedules, expect 300-500 operating hours before top-end service. Regular oil quality and clean air filtration extend lifespan significantly.
Q: Can this engine handle high-altitude operations?
A: Yes. While power output decreases slightly at elevation (7.5kg at 1800m vs. 8.5kg at sea level), the product maintains reliable performance across altitude ranges.
Q: What spark plug replacement interval do you recommend?
A: Inspect BM6A spark plugs every 50 hours. Replace every 100 hours or sooner if electrode wear is visible. Proper gap maintenance ensures consistent ignition.
Q: How does air cooling compare to liquid cooling for my application?
A: Air cooling eliminates leak risks, reduces weight by 15-20%, and requires zero coolant maintenance. It's ideal for portable equipment, remote operations, and applications where simplicity matters.
Q: What propeller size works best for drone applications?
A: Start with 18×8 or 18×10 configurations. Adjust based on your payload and desired flight characteristics. Our technical team can provide specific recommendations.
