3. Dimensional Parameters

Length (X)

The length of the FB200 engine varies depending on the presence of the forced air - cooling system. Without the system, it measures 730mm, and with the forced air - cooling system installed, it extends to 895mm. This variation in length is an important consideration for aircraft manufacturers and designers, as it impacts the engine's fit within the aircraft's engine bay. The forced air - cooling system, when used, enhances the engine's cooling capacity, allowing it to operate more efficiently under different conditions, but at the cost of increased length.

Width (Y)

With a width of 739mm, the FB200 engine has a relatively compact footprint in terms of width. This dimension is crucial for ensuring that the engine can be integrated into a variety of aircraft designs without excessive modification to the airframe.

Height (Z)

Similar to the length, the height of the engine also changes with the forced air - cooling system. Without the system, the height is 530mm, and with it, it reaches 588mm. The height dimension, like the others, plays a vital role in determining the engine's compatibility with different aircraft models and their respective design constraints.

4. Displacement and Cylinder - related Parameters

Displacement

The engine has a displacement of 5208cc. Displacement is a key indicator of an engine's potential power output, as it represents the total volume of all the cylinders. In the case of the FB200, this displacement, combined with its six - cylinder design, contributes to its ability to generate sufficient power for aviation applications.

Bore and Stroke

The bore of the FB200 engine is 105mm, and the stroke is 100mm. The bore - stroke ratio has a significant impact on the engine's power characteristics. A larger bore can allow for larger valves, promoting better air and fuel intake, while the stroke length affects the engine's torque output. In the FB200, this specific combination of bore and stroke is optimized for its aviation role, balancing power and efficiency.

Compression Ratio

With a compression ratio of 8.7:1, the FB200 engine is designed to efficiently compress the air - fuel mixture within the cylinders. The compression ratio influences the engine's thermal efficiency, with a higher ratio generally leading to better efficiency, but also requiring higher - quality fuel to prevent knocking.

5. Firing Order and Rotation

Firing Order

The firing order of the FB200 engine is 1 - 4 - 5 - 2 - 3 - 6. This carefully designed firing order ensures smooth and balanced operation of the six - cylinder engine. By sequencing the ignition of the cylinders in this manner, the engine can minimize vibrations and maximize power delivery, which is crucial for maintaining stability during flight.

When viewed from the rear of the engine, the FB200 rotates clockwise. This rotation direction is an important factor when integrating the engine with other components such as the propeller and the aircraft's transmission system. It ensures proper meshing and operation of all related parts.

6. Power and Torque Parameters

Maximum Torque

The FB200 engine can generate a maximum torque of 475Nm at 2800RPM. Torque is the rotational force that the engine produces, and in aviation, it is essential for tasks such as takeoff and climbing. This level of torque, at this specific RPM, allows the engine to provide the necessary force to get an aircraft off the ground and maintain a steady climb.

Maximum Power

It has a maximum power output of 200hp at 3200RPM and 185hp at 2800RPM. Power output is a critical parameter for an aviation engine, as it determines the aircraft's speed and overall performance capabilities. The ability to produce different power levels at different RPMs allows the engine to be versatile in various flight phases, from takeoff (where higher power at lower RPMs might be beneficial) to cruising (where a balance of power and efficiency is required).

7. Electrical and Lubrication Parameters

DC Output

The engine provides a DC output of 50A. This electrical output is used to power various aircraft systems, such as avionics, lighting, and other electrical components. A stable and sufficient DC output is essential for the reliable operation of these systems during flight.

Engine Oil Capacity and Type

The engine oil capacity of the FB200 ranges from a minimum of 3.5L to a maximum of 4.5L, with a recommended capacity of 4L. The oil type used is 15W50. Engine oil plays a crucial role in lubricating the engine's moving parts, reducing friction, and dissipating heat. The specified oil type and capacity are chosen to ensure optimal lubrication and cooling under the engine's operating conditions.

8. Fuel - related Parameters

Fuel Types

The FB200 engine is compatible with multiple fuel types, including 98# automotive gasoline, 100LL aviation gasoline, and UL91 (with a specification of 980TC = 90MON = 94AKI). This flexibility in fuel choice is a significant advantage, as it allows the engine to be used in different regions and situations where fuel availability may vary.

9. Weight Parameters

Total Operating Weight

The total operating weight of the engine varies depending on the presence of the forced air - cooling system. Without the system, it is 117.5KG, and with the system, it is 129.7KG. This total operating weight includes all the necessary fluids and components required for the engine to function, and it is a key consideration for aircraft manufacturers when calculating the aircraft's overall weight and balance.

10. Additional Components and Their Weights

Ignition and Control Components

The ignition coil and lead (dual ignition) weigh 4.7KG, and the electronic control unit and harness (dual ECU) weigh 3.9KG. These components are essential for the proper ignition and control of the engine's combustion process. Their weights contribute to the overall weight of the engine system and need to be accounted for in aircraft design.
