The OKMO 1110 engine is a newly launched miniature four-stroke water-cooled engine model. Its prototype is the Yanmar 1110 Engine produced between 1976 and 1983. As the mainstay of its era, the Yanmar 1110 engine boasted exceptional reliability, high efficiency, and a simple design, finding widespread use in compact agricultural tractors.
Originating from agricultural machinery, the 1110 engine holds immense significance for those engaged in farming and agricultural equipment. OKMO specially introduces this replica 1110 engine model to pay homage to the classic while offering enthusiasts a unique collectible experience.
OKMO 1110 Engine Design Highlights
The OKMO 1110 model seamlessly blends classic retro engineering aesthetics with practical functionality. As a versatile power unit, it features a 19mm stroke and 16mm bore engine, serving as a reliable power source for applications such as pumps, grinding equipment, and mechanical generators.
To ensure overall operational stability and extend engine longevity, the model's cylinders are CNC-machined, achieving high-precision component alignment.
Additionally, a comprehensive lubrication system has been engineered. The engine incorporates a metal ring design, with oil flowing through connecting rod oil passages to thoroughly lubricate the piston and camshaft. The piston features two compression rings and one oil ring, effectively preventing oil-gas leakage while enhancing sealing and engine performance.
The ignition system employs a new mechanical ignition method, ensuring precise and reliable spark delivery. A filter is installed at the oil inlet to prevent contaminants from entering the oil system, protecting internal engine components from wear.
Finally, a large-capacity radiator design ensures excellent cooling performance during extended operation, preventing performance degradation or failure due to overheating. This superior cooling capability allows the 1110 engine model to run longer, delivering smoother starts and a more enjoyable viewing experience.
