Product introduction: Following the widespread acclaim of the CISON L4-175 engine in November 2022 and the L4-205 engine in February 2025, we are officially launching the newly upgraded CISON L4-26CC micro inline four-cylinder engine, continuing its classic advantages while achieving a double leap in power and experience! This engine inherits the family's micro and compact structural design, taking into account installation flexibility and space adaptability. It comes standard with electric start, three piston rings, a wet water cooling system, and an independent lubrication system, coupled with a four-in-one CDI direct ignition scheme to ensure smooth starting and stable operation. The exterior returns to a classic look, with a red top cover paired with a silver cylinder block, combining aesthetic appeal and collectability. A new integrated exhaust manifold delivers a more distinctive engine sound. The upgraded independent carburetor not only makes tuning easier but also significantly improves running smoothness and reliability. Core performance has been comprehensively evolved, with the displacement increased from 20.5cc to 26cc (bore and stroke increased simultaneously), resulting in a power output increase of over 20%. It also boasts stronger compatibility with RC car models, meeting the needs of both modification upgrades and collection display. The product still offers two options—a kit version and a pre-assembled complete version—to suit the DIY needs and usage scenarios of different users.
Product Features:
1. Immersive Engine Building Experience: Step into the wonderful realm of micro-mechanical engineering. This L4 engine kit brings you a highly challenging and rewarding project. Containing hundreds of meticulously crafted metal parts, you will personally DIY step by step to build your own unique L4 engine and experience the infinite charm of mechanical assembly.
2. Compact and Powerful Micro-Power: The L4 engine boasts a uniquely compact and compact design. Despite its small size, it packs a powerful punch. Featuring a large displacement design, an advanced OHV valve train, and a long stroke, it delivers high torque output, far exceeding the performance of similarly sized engines.
3. Durable and Stable Operation: Equipped with an independent lubrication system and an external oil pump, it ensures excellent lubrication. Using a micro oil filter is highly recommended. Utilizing wet water cooling technology, it effectively reduces engine operating temperature, significantly extending engine lifespan and ensuring stable and reliable performance.
4. Sensitive Response and Powerful Sound: Both the intake and exhaust pipes are integrally molded from stainless steel, paired with a biomimetic single carburetor for easy and convenient tuning. The throttle response is extremely sensitive, providing a first-class driving experience, and the engine emits a deep and powerful sound, delivering an exceptional auditory experience.
5. Exquisite Craftsmanship, Superior Quality: The engine body is precision-machined by CNC, featuring a three-ring design (piston ring + compression ring + oil ring), high-precision hardened cylinder liners, and a one-piece hardened and thickened crankshaft. Every component is meticulously crafted. The surface undergoes sandblasting and oxidation treatment, combining both texture and aesthetics.
6. Convenient and Stable Ignition: Equipped with a dedicated CDI igniter for L4 engines, it is compact and has strong anti-interference capabilities. This ensures stable engine ignition and provides more reliable protection for players using remote control electronic devices, making operation smoother and worry-free.
7. Perfectly Compatible with RC Models: Utilizing a lightweight structural design, it boasts excellent compatibility with RC models. It is particularly suitable for 1/8 and 1/14 scale model crawlers, off-road vehicles, and tractor trucks that require high torque, acting like a tailor-made "heart" for these model cars, giving them powerful performance and outstanding capabilities.
8. An Excellent Gift for Enthusiasts: Whether you are a mechanical engineering enthusiast, an engine model aficionado, or a collector, this product is the perfect addition to your collection. It also serves as an excellent power alternative for RC nitro-powered off-road model cars. Giving it as a high-end, personalized gift to family and friends will surely bring them surprise and delight.
9. Important Note: This engine product does not include the starter harness module, CDI igniter, spark plugs *4, oil filter, water-cooling components, base, battery, charger, etc. Please strictly follow the instructions in the manual to avoid damage caused by improper operation. If you have any questions during use, please contact us promptly; we will be happy to assist you.
