CISON L4-175 17.5cc OHV Engine A Miniature 4-Stroke Gasoline DIY Kit for RC Car and Boat Models

Introducing the CISON L4-175, the advanced OHV evolution of the classic flathead engine. This 17.5cc inline four-cylinder gasoline engine is engineered for high performance, maintaining a compact footprint while delivering significant power. Compared to its predecessor, this model features a sophisticated Overhead Valve (OHV) mechanism, which enhances power output and provides higher torque. This makes it an ideal choice for demanding RC applications, including off-road trucks, crawlers, and tow vehicles.

Visually, the engine stands out with red sport accents and is meticulously constructed for both performance and aesthetics. It comes standard with an electric starter, an efficient water-cooling system, and an independent lubrication system for enhanced durability. This engine is available as a comprehensive DIY kit for an immersive building experience or as a professionally pre-assembled version for immediate use.

Key Features:

Engaging DIY Assembly: The kit version provides a challenging and rewarding project with hundreds of precision metal parts. It offers a unique opportunity to delve into the world of micro-mechanical engineering as you build your own high-performance L4 engine from scratch.
Responsive and Powerful: The engine features integrated stainless steel intake and exhaust pipes and a precision-engineered carburetor for easy adjustment, sensitive throttle response, and a deep, powerful exhaust note.
Durable and Efficient Operation: A dedicated independent lubrication system, utilizing an external oil pump and compatible with mini oil filters, provides superior protection for internal components. The water-cooling system ensures stable operating temperatures for extended run times and a longer engine lifespan.
High-Precision Construction: The main body is crafted from CNC-machined aluminum with a sandblasted, oxidized surface for a stunning texture and appearance. Internal components include a special bimetal cast iron piston ring, a high-precision hardened cylinder liner, and an integral hardened crankshaft for maximum durability.
Reliable Electronic Ignition: The engine is designed for use with a dedicated CDI igniter that offers a compact size and excellent anti-interference performance. This ensures stable ignition and is friendly to other remote control electronic devices.
Optimized for RC Models: This lightweight engine serves as an incredible "heart" for various RC models. It is particularly well-suited for 1/8 and 1/14 scale crawlers, off-road vehicles, and tractor models that require significant low-end torque.
A Collector's Item and Premium Gift: This engine is a perfect addition for machine enthusiasts, engine model collectors, and RC hobbyists. Packaged beautifully, it makes a high-end, personalized gift for family and friends.

Please Note: The base, CDI igniter, spark plug, oil filter, battery, and water cooling accessories are not included. Please operate the engine according to the instructions to ensure proper performance and avoid damage.
