Enjomor GS-L4 32cc DOHC Inline 4 Cylinder 4 Stroke Gasoline Engine Model 12000rpm
Hero Section: The Scream of 12,000 RPM
There is a distinct difference between a standard engine and a performance machine: the redline. The Enjomor GS-L4 isn't just a model; it is a high-revving mechanical beast capable of hitting a screaming 12,000 RPM. Featuring a genuine Dual Overhead Camshaft (DOHC) design, this 32cc inline-four brings the sophisticated engineering of a modern sports car engine to your workbench. Whether you are powering a 1/5 scale RC supercar, a high-speed boat, or simply seeking the ultimate kinetic display, the GS-L4 delivers a symphony of precision, power, and speed.
Why Choose the Enjomor GS-L4?
- True DOHC Architecture: Most scale engines settle for simple valve trains. The GS-L4 features a Dual Overhead Camshaft structure. This allows for precise valve timing at high speeds, better airflow, and that signature high-performance look and sound.
- 12,000 RPM Redline: This engine is built to rev. With a lightweight rotating assembly and efficient breathing, it pushes the boundaries of miniature engineering, delivering an adrenaline-pumping 1.8kw of power.
- Automotive-Grade Internals: Reliability is key. Each piston is equipped with three rings (two compression rings and one oil ring). This ensures maximum cylinder sealing, high compression, and zero blow-by, just like a full-sized vehicle.
- The Ultimate "Heart": For the builder looking for a challenge, this engine is the perfect centerpiece. It transforms any RC chassis or custom project into a professional-grade machine, offering a hands-on lesson in advanced internal combustion mechanics.
Technical Highlights: Engineering Deep Dive
- Independent Lubrication System: Unlike simple 2-stroke engines that burn oil, the GS-L4 features a dedicated oil pump and wet sump system. It circulates oil continuously to the crankshaft and camshafts, ensuring durability during those high-RPM runs.
- Brushless Electric Start: Forget pull cords. The engine is integrated with a powerful brushless starter motor. With the press of a button, the engine fires up instantly, offering a seamless and premium user experience.
- Active Water Cooling: To manage the heat generated at 12,000 RPM, the engine features a high-efficiency water-cooling jacket. When paired with a radiator (sold separately), it maintains stable operating temperatures for extended play sessions.
- CDI Ignition with Distributor: The ignition system uses a Hall-sensor CDI paired with a mechanical distributor, ensuring that each of the four cylinders fires at the exact microsecond required for smooth power delivery.

Usage Scenario: The High-Speed Test
You secure the GS-L4 to your test bench. You connect the cooling lines and the dual battery systems (12V for ignition, 24V for the starter). You flip the ignition switch. You press the start button on the ESC controller. The brushless motor whines, and the engine catches immediately. It settles into a smooth, complex idle. Then, you open the throttle. The sound transforms from a rumble to a Formula-1 style scream as it climbs to 12,000 RPM. The vibration, the sound, the heat—it’s pure mechanical exhilaration.
Important Tips from the Workshop
- Dual Power Requirement: This engine requires two separate power sources. You need a 10-12V battery for the CDI ignition and a separate 24V-48V battery (e.g., 6S LiPo) to power the 80A ESC for the starter motor.
- Oil is Mandatory: Because this engine uses an independent lubrication system, you must fill the sump with 50mL of low-viscosity oil (0W-20W) before starting. Running it dry will destroy the bearings.
- Cooling Loop: Do not run this engine without a water pump and radiator connected. The high power output generates significant heat that must be dissipated.
- Break-in: Despite the high redline, run the engine at moderate speeds for the first few tanks of fuel to allow the three-ring pistons to seat perfectly against the cylinder liners.
