CISON V8 Engine Pro Small-block 44CC 1/6 Scale Water-Cooled 4-Stroke 8-Cylinder Gasoline Engine Internal Combustion V8 Engine Model Kit that Works

Know More About CISON Small-block V8 Pro Engine:

CISON Small-block V8 Pro 44cc Engine Kit is a 1/6 scale high-performance DIY model that replicates a real V8 gasoline engine with impressive detail and functionality. Featuring a top-mounted valve (OHV) design, this four-stroke, water-cooled internal combustion engine delivers powerful performance and mechanical authenticity. Perfect for RC model upgrades, engineering education, or desktop display,

New vs. Old – Key Upgrades:

Structural Reinforcement: The engine now uses flange bearings on both the front and rear of the cylinder block, eliminating previous wear issues caused by bearing shifting. This significantly enhances stability and durability during operation.

Performance Optimization: Compression ratio has been re-calibrated to reduce fuel injection needs and improve spark plug longevity. These adjustments resolve common wear issues and deliver smoother, more stable power output.

Improved Smoothness: The carburetor rotor has been hardened for smoother rotation without jamming, addressing defects found in ordinary steel parts. Paired with a distributor that adjusts ignition timing with throttle input, the engine supports lower idle speeds and higher peak performance.

Durability Enhancement: Upgraded coated pistons offer 200% improved wear resistance and corrosion protection. Added valve stem seals and optimized rocker lubrication reduce oil burning and fuel spraying, greatly extending engine lifespan.

Premium User Experience: Delivered in an all-new deluxe V8 PRO gift box with top-and-bottom case design. Whether for desktop display, RC model upgrades, or as a luxurious gift, it delivers a refined and impressive presence.

.DIY Fun:

Crafted with high-precision parts, and easy-to-follow assembly instructions for a deep understanding of engine structure and mechanical principles.

.Highly Realistic:
Adopt exquisite electroplated paint for a lifelike engine appearance, suitable for real fuel operation, and provides a location for optional generator installation.

.Precision Manufacturing:

The cylinder is precision machined with 5-axis CNC, with repeatability within 0.005mm for better assembly accuracy.

.Long Stroke:

High-angle, high-hardness wear-resistant camshaft, 4-point supported camshaft, larger intake valve, unaffected by temperature changes with low-temperature intake pipe.

.Crankshaft and Connecting Rods:

Reinforced and hardened wear-resistant connecting rods, optional dual cast iron piston rings (oil rings are optional), 5-point supported crankshaft for increased high-speed operational strength and stability.

.Durable Operation:

Equipped with a double-layer gear pump water pump, independent lubrication system, and reserved oil filter installation position. This model in the OHV version can be combined with a rocker arm forced lubrication system with rocker arm lubricant returning to the cylinder block holes, and an oil sump with an oil level gauge.

.Creative Gift:

The assembled model is perfect as a collectible desktop engine model or be installed in RC models, as well as a premium model holiday gift.
