Kohler K361 Engine Specification

The Kohler K361 engine is a robust, air-cooled, four-cycle gasoline engine designed to deliver reliable performance for a variety of industrial and heavy-duty applications. This single-cylinder engine features a cast iron cylinder bore and an overhead valve (OHV) design, which enhances efficiency and power output while maintaining durability. With a displacement of 18.6 cubic inches (305 cc), the K361 engine is capable of producing up to 12 horsepower, making it suitable for tasks requiring substantial power.

The engine operates at a rated speed of 3600 RPM, providing consistent and stable output. It incorporates a solid-state ignition system, which ensures dependable starting and smooth operation. The lubrication system is splash-type, which effectively reduces friction and wear on internal components, thereby extending the engine's lifespan. Fuel is delivered via a float-type carburetor, optimizing air-fuel mixture for better combustion efficiency.

The Kohler K361 engine also comes equipped with a recoil start mechanism, although an electric start option may be available as well, providing flexibility for different operational needs. The engine's cooling system relies on a flywheel fan to maintain optimal operating temperatures, preventing overheating during extended use. Its compact design facilitates easy integration into various equipment, while the robust construction ensures longevity and reliability.

Overall, the Kohler K361 engine is engineered to provide durable performance and efficient operation in tough working environments, making it a preferred choice for equipment manufacturers and operators seeking an engine that balances power and dependability.
