Build It. Start It. Watch a Real Twin-Cylinder Engine Come to Life.

The ENGINEKITOR F2 is a real working 7.5cc inline twin-cylinder, 4-stroke gasoline engine model kit designed for builders who want more than a static display model.

Featuring an SOHC valve train, circulating water cooling, CDI electronic ignition and an electric starting system, the F2 gives you the opportunity to assemble, understand, start and explore a genuine miniature internal combustion engine.

• Real Working 7.5cc Gasoline Engine
• Inline Twin-Cylinder Design
• 4-Stroke Internal Combustion
• SOHC Valve Train
• Approx. 1,600–12,000 RPM
• Circulating Water Cooling
• Mechanical Water Pump
• CDI Electronic Ignition
• Electric Motor Start
• Precision Metal Construction
• Build, Run, Tune & Explore

---

A Real Engine — Not Just a Display Model

The ENGINEKITOR F2 reproduces the essential mechanical systems of a full-size four-stroke internal combustion engine on a compact scale.

Inside the engine, two pistons, connecting rods, a crankshaft, camshaft and valves work together through the complete four-stroke cycle:

Intake → Compression → Power → Exhaust

Once correctly assembled and connected to the required fuel, ignition and cooling systems, the engine can actually start and run.

You are not simply assembling parts that imitate an engine. The F2 is designed to let you build and operate a real miniature internal combustion engine.

---

Twin-Cylinder 4-Stroke Performance

The F2 uses two 3.75cc cylinders for a total displacement of 7.5cc.

Its inline twin-cylinder configuration introduces more mechanical interaction than a conventional single-cylinder miniature engine.

During assembly and operation, builders can observe:

• Crankshaft movement
• Piston synchronization
• Camshaft operation
• Valve timing
• Intake and exhaust cycles
• Ignition timing
• Twin-cylinder combustion behavior

The result is a compact working engine with authentic mechanical motion and the distinctive operating character of an inline twin-cylinder design.

---

Active Circulating Water Cooling

Real combustion produces real heat.

The ENGINEKITOR F2 uses a circulating water-cooling system with an integrated mechanical water pump to help manage engine temperature during operation.

When used with the complete starter setup, coolant can circulate between the engine and radiator while the engine is running.

This means the cooling system is more than a decorative feature. It becomes another functional system that builders can connect, observe and understand as part of the complete engine.

---

SOHC Valve Train

The F2 features a Single Overhead Camshaft (SOHC) design.

The camshaft controls the opening and closing of the intake and exhaust valves while remaining mechanically synchronized with the crankshaft.

During assembly, builders can directly see how several important four-stroke engine systems interact:

• Crankshaft position
• Piston movement
• Camshaft rotation
• Intake valve timing
• Exhaust valve timing
• Ignition timing
• The four-stroke combustion cycle

This exposed mechanical relationship makes the F2 particularly useful for hobbyists who want to understand how a real four-stroke engine works, rather than only watching external parts move.

---

Electric Start + CDI Electronic Ignition

The ENGINEKITOR F2 uses an electric starter motor together with a CDI electronic ignition system.

Hall sensing and spark plugs provide controlled ignition while the electric starter rotates the engine during the starting process.

The operating sequence can be understood simply as:

Fuel & Air → Compression → Spark → Combustion → Mechanical Power

The electric starter helps initiate the process, but once the engine is successfully running, combustion inside the cylinders produces the engine's mechanical motion.

---

Built to Run, Tune & Explore

Assembly is only the beginning.

Once the engine is correctly assembled and running, the F2 gives experienced builders an opportunity to explore real operating behavior, including:

• Engine startup
• Idle adjustment
• Throttle response
• Fuel mixture behavior
• Operating RPM
• Ignition behavior
• Cooling performance
• Mechanical synchronization

The published operating range is approximately:

1,600–12,000 RPM

For experienced hobbyists, the compact engine may also serve as a foundation for custom mechanical or RC projects where suitable mounting, transmission, controls and cooling systems are provided.

Intake → Compression → Power → Exhaust

Once correctly assembled and connected to the required fuel, ignition and cooling systems, the engine can actually start and run.

You are not simply assembling parts that imitate an engine. The F2 is designed to let you build and operate a real miniature internal combustion engine.

---

Twin-Cylinder 4-Stroke Performance

The F2 uses two 3.75cc cylinders for a total displacement of 7.5cc.

Its inline twin-cylinder configuration introduces more mechanical interaction than a conventional single-cylinder miniature engine.

During assembly and operation, builders can observe:

• Crankshaft movement
• Piston synchronization
• Camshaft operation
• Valve timing
• Intake and exhaust cycles
• Ignition timing
• Twin-cylinder combustion behavior

The result is a compact working engine with authentic mechanical motion and the distinctive operating character of an inline twin-cylinder design.

---

Active Circulating Water Cooling

Real combustion produces real heat.

The ENGINEKITOR F2 uses a circulating water-cooling system with an integrated mechanical water pump to help manage engine temperature during operation.

This means the cooling system is more than a decorative feature. It becomes another functional system that builders can connect, observe and understand as part of the complete engine.

---

SOHC Valve Train

The F2 features a Single Overhead Camshaft (SOHC) design.

The camshaft controls the opening and closing of the intake and exhaust valves while remaining mechanically synchronized with the crankshaft.

During assembly, builders can directly see how several important four-stroke engine systems interact:

• Crankshaft position
• Piston movement
• Camshaft rotation
• Intake valve timing
• Exhaust valve timing
• Ignition timing
• The four-stroke combustion cycle

This exposed mechanical relationship makes the F2 particularly useful for hobbyists who want to understand how a real four-stroke engine works, rather than only watching external parts move.

---

Electric Start + CDI Electronic Ignition

The ENGINEKITOR F2 uses an electric starter motor together with a CDI electronic ignition system.

Hall sensing and spark plugs provide controlled ignition while the electric starter rotates the engine during the starting process.

The operating sequence can be understood simply as:

Fuel & Air → Compression → Spark → Combustion → Mechanical Power

The electric starter helps initiate the process, but once the engine is successfully running, combustion inside the cylinders produces the engine's mechanical motion.

---

Built to Run, Tune & Explore

Assembly is only the beginning.

Once the engine is correctly assembled and running, the F2 gives experienced builders an opportunity to explore real operating behavior, including:

• Engine startup
• Idle adjustment
• Throttle response
• Fuel mixture behavior

TECHING ORR-S1 All-Metal Mechanical Solar System Orrery Model with Precision Gear Drive

The ENGINEKITOR ORR-S1 is a mechanically driven solar system orrery designed to demonstrate planetary motion through real gear transmission.
Inspired by classical astronomical instruments, this model transforms the movement of the solar system into a visible, synchronized mechanical process.

Unlike decorative planet displays, the ORR-S1 uses a multi-layer concentric gear system to drive each orbit independently, allowing all planets to rotate smoothly and simultaneously around a central sun reference.

Real Mechanical Orbit System

At the heart of the ORR-S1 is a precision electric drive that transfers power through multiple levels of interlocking gears.
Each planetary arm is mounted on its own orbit track, powered by calibrated gear ratios that control rotational speed and direction.

When operating, the system clearly demonstrates:

• Centralized power input

• Radial mechanical transmission

• Multi-orbit synchronized motion

• Continuous and stable rotation

All movement is generated by real mechanical components — no digital animation or simulated effects.

Eight-Planet Configuration with Central Sun

The ORR-S1 represents a complete solar system structure with a central sun and eight orbiting planetary bodies.
Each planet is positioned on an individual orbit arm, creating a layered, three-dimensional representation of orbital motion.

The illuminated central sun enhances visibility while serving as a fixed reference point, making orbital relationships easier to observe during operation.

All-Metal Construction & Precision Machining

Every major structural and motion-related component is made from metal, providing durability, stability, and long-term reliability.
The exposed gear layout allows users to visually study how mechanical power is distributed across multiple orbits.

Key construction features include:

• CNC-machined metal gears

• Rigid metal orbit arms

• Stable weighted base for vibration control

• Smooth, low-noise mechanical operation

This construction ensures consistent performance during extended display or demonstration use.
