In the dynamic landscape of aviation technology, Changzhou Zhonglian Aviation stands out with its innovative solutions. Central to our offerings is the Flyben22 helicopter and the independently - developed Flyben four - cylinder turbocharged FB160T engine. This FAQ - style article aims to address key queries, with a focus on “Flyben22's Four - Cylinder Turbocharged FB160T Engine”, to help you understand our products better.
We are a comprehensive aviation enterprise overseen by Mr. Shen Benzhong. We manage two core businesses: one is dedicated to manufacturing high - quality helicopters (including the Flyben22 model), and the other focuses on researching and developing the advanced Flyben engine series, such as the four - cylinder turbocharged FB160T engine. Our goal is to provide top - notch aviation products and services, catering to diverse client needs in the global market. We welcome clients worldwide to visit our Changzhou, Jiangsu, China headquarters, where they can witness our production processes and commitment to quality.

The FB160T engine is a four - cylinder, four - stroke, horizontally opposed engine. It adopts full - engine air cooling, a turbocharging system, a dual - electronic spark ignition system, and electronic fuel injection. These features contribute to its efficiency and performance. For example, the turbocharging system enhances power output, while the dual - electronic spark ignition ensures reliable ignition.
· Dimensions: Length X is 520mm, Width Y is 739mm, and Height Z is 490mm. These compact dimensions allow for flexible installation in the Flyben22 helicopter.
· Displacement: With a displacement of 3520cc, it can generate sufficient power. The bore is 105.7mm and the stroke is 100.2mm, which are optimized for power and efficiency.
· Compression Ratio: An 8.1:1 compression ratio helps in efficient fuel combustion.
· Altitude and Rotation: It has a maximum boost altitude of 6500m and rotates clockwise when viewed from the rear of the engine.
· Power and Torque: The maximum torque is 390Nm (145hp) at 3000rpm, and the maximum power is 170hp (370Nm) at 3300rpm. This power output ensures the Flyben22 helicopter has good performance.
· Other Features: It has a 30A (13.7V) generator, an engine oil capacity of 3.3L (MIN: 2.8L - MAX: 3.5L), and can use 98# Gasoline or 100LL Aviation Gasoline. The engine dry weight is 81.2KG, and the total operating weight is 94.5KG.

The Flyben22 helicopter has a dry weight of 300 kg. When equipped with the 90 - kg FB160T engine (our independently developed four - cylinder aero - engine), its total weight reaches 390 kg. This self - developed engine boasts better performance, making it a competitive choice.
The turbocharging and efficient ignition systems (dual - electronic spark ignition) of the FB160T engine provide the necessary power for the Flyben22. It enables the helicopter to have a good climb rate, cruise speed, and payload capacity. For example, the power output allows the Flyben22 to carry out various missions, from training to light utility tasks.
The FB160T engine features dual ignition, which is a significant advantage. This distinct ignition system option ensures that even in case of a partial ignition system failure, the engine can still operate reliably. It provides an extra layer of safety, which is crucial for aviation applications.
We plan to apply to CAAC for the light sport airworthiness certificate using the four - cylinder turbocharged Flyben engine (including the FB160T used in Flyben22). The Flyben engine, with its dual ignition and other advanced features, is suitable for aviation use. However, the airworthiness certification process is time - consuming as it involves rigorous testing and verification. We are committed to this process and will inform you as soon as we succeed in obtaining the certificate.
Our helicopter company, overseen by Mr. Shen Benzhong, offers flexibility in engine selection. Customers can choose either Subaru engines or Flyben engines (like the FB160T) based on their specific needs. This flexibility allows clients to balance factors such as performance, cost, and existing preferences. For example, if a customer values the independent innovation and features of our Flyben engine (such as dual ignition), they can opt for it. If they have experience with Subaru engines and prefer their characteristics, that option is also available.


Mr. Shen Benzhong, as the chairman, plays a crucial role in ensuring the quality and meeting diverse client requirements of both enterprises. For the helicopter manufacturing business, he focuses on maintaining high - quality production standards, ensuring that each Flyben22 helicopter is built to precision. For the Flyben engine research and development company, he drives innovation, making sure that engines like the FB160T are at the forefront of aviation technology. His leadership ensures seamless integration between the engine development and helicopter production, resulting in products that are both reliable and high - performing.
When clients visit our Changzhou, Jiangsu, China headquarters, they can expect a comprehensive and rewarding experience. They will have the opportunity to see our helicopters in various stages of production, from raw materials to fully - assembled aircraft. This allows them to understand our manufacturing processes, which involve strict quality control at every step. They can witness our commitment to quality, from the selection of components to the final assembly and testing of the helicopters. We provide good services, ensuring a smooth and convenient stay, including accommodation and transportation arrangements. Our goal is to make the visit memorable and showcase our capabilities as a leading manufacturer in the aviation industry.
The FB160T engine is independently developed by our company, which is a testament to our innovation and technical strength. Designing and manufacturing a four - cylinder, turbocharged, horizontally opposed engine with features like dual - electronic spark ignition and electronic fuel injection requires in - depth knowledge of aviation engineering. The engine's performance parameters, such as its power output, altitude capability, and ignition system, show that we have the technical expertise to develop advanced aviation engines. This not only benefits our Flyben22 helicopter but also positions us as an innovative player in the aviation engine market.
We are constantly looking to improve and innovate. For the FB160T engine, future development plans may include further optimization of fuel efficiency, potentially expanding the range of compatible fuels, and enhancing its performance at extreme altitudes or in different environmental conditions. We also aim to integrate more smart features into the engine management system, which could improve diagnostics and maintenance. As we move forward with the airworthiness certification process, we will also use the feedback from potential clients and industry experts to refine the engine further.
