15cc Vertical OHV 4-Stroke Gasoline Engine Model Industrial Internal Combustion Motor with Independent Lubrication
Hero Section: A Tribute to Industrial Power
There is a unique beauty in the raw, unshielded machinery that built the modern world. This 15cc Vertical OHV Engine captures that essence perfectly. It isn't a fragile toy; it is a 1.9kg masterpiece of CNC-machined metal, designed to bring the thunder of a heavy industrial generator to your desktop. With a massive 15cc displacement, this engine offers a deep, resonant idle and torque that you can feel. Whether you are an experienced machinist or a collector seeking the ultimate mechanical display, this engine delivers an experience that is authentic, powerful, and visually arresting.
Why Choose This 15cc Industrial Engine?
- See the Mechanics (Perspective View): Designed with a "half-perspective" window and a flexible opening cylinder head, this model tears down the walls between you and the machine. Watch the internal combustion process, the valve train movement, and the piston stroke in real-time.
- True Wet Sump Lubrication: Unlike smaller models that burn mixed fuel, this beast uses an independent lubrication system. You fill the crankcase with 4T engine oil (5W40), just like a real car. This ensures longevity and provides a realistic maintenance experience.
- Extreme Precision Manufacturing: Every aluminum part is CNC machined with 0.02mm precision. The crankshaft undergoes 40Gr quenching and tempering, then hard chrome electroplating to achieve a hardness of 55HRC. This is military-grade build quality.
- Massive 15cc Displacement: In the world of model engines, 15cc is huge. It provides a stable, low-RPM idle (800 RPM) that sounds like a vintage tractor, yet it can rev up to 5000 RPM when you open the throttle.
Technical Highlights: Engineering Insight
- OHV Architecture: The Overhead Valve design allows for efficient airflow and creates the classic rocker-arm movement that gearheads love to watch.
- Durability Focus: The main shafts and gears utilize shrink-fit assembly for a bond that won't vibrate loose. The valves are treated for heat resistance, ensuring the engine can run for sustained periods (up to 30 mins) without overheating.
- Ignition System: Equipped with a reliable CDI electronic ignition for easy starting via the manual pull rope.

Usage Scenario: The Mechanic's Meditation
You place the heavy engine on your workbench. You unscrew the dipstick and pour in the golden 5W40 oil. You check the fuel lines. You grab the starter rope and give it a firm pull. Thump... Thump... THUMP! The engine roars to life, settling into a heavy, rhythmic beat. You watch through the inspection window as the oil splashes and the piston drives up and down. For the next 30 minutes, you aren't just a spectator; you are the operator of a miniature power plant.
Important Tips from the Expert
- Version Note: Please check your selection carefully. The Simple Edition typically includes the engine and igniter but excludes the base, fuel tank, and power distribution box. If you want a "Ready-to-Run" experience out of the box, we recommend the High-End Edition or be prepared to mount it yourself.
- Oil is Mandatory: This is a 4-stroke engine with independent lubrication. You MUST add oil to the crankcase before starting. Running it dry will destroy the precision bearings instantly.
- Break-in: Run the engine at moderate RPMs for the first few tanks of fuel to allow the piston rings to seat properly against the cylinder wall.
