Core Independent Technical Highlights
V4‑Generation Intelligent ECU Control Unit
This UAV gasoline engine is equipped with upgraded V4‑generation digital ECU. It reads multi‑channel sensor data and precisely regulates fuel‑delivery volume, ignition timing and brushless starter operation to maintain stable engine running status. The built‑in fault‑diagnosis module records runtime error information and stores fault codes inside onboard memory chip; visual alarms will be triggered once abnormal states occur to facilitate inspection work for technicians.
The ECU dynamically monitors ambient atmospheric pressure and temperature, and automatically adjusts internal operating parameters to adapt to extremely cold or hot field environments. Firmware upgrade is supported, allowing users to modify engine performance parameters to satisfy personalized civilian mission demands. It can also send control instructions and collect feedback data for TCU execution units.
High‑Performance Brushless Starter Motor
The proprietary brushless starting motor matched for this drone gasoline engine removes carbon‑brush components, eliminating electric‑spark interference generated by traditional brushed starters and protecting onboard wireless remote‑control and telemetry equipment. It features wide speed‑regulating range, low steady‑state speed error and high energy efficiency; its power consumption is far lower than comparable brushed starter motors.
Compact lightweight dimensions provide high installation flexibility for airframe designers. Without easily‑worn brush consumable parts, the starter assembly delivers higher mechanical reliability, smoother running performance and lower operational noise during frequent cold‑start cycles.
Enhanced Self‑Priming Fuel Supply System
The matched fuel system is fully compatible with multiple mainstream SWIWIN civilian turbojet engine series. It adopts compact miniaturized layout and occupies limited cabin installation space. The pump unit provides powerful self‑priming performance and maintains stable fuel suction under high‑speed, low‑speed or manual priming conditions.
It can reliably transport medium‑high‑viscosity aviation kerosene and lubricants. The whole fuel assembly works stably within ‑40℃ to +50℃ temperature range with even flow and steady oil pressure. The structural design brings low failure rate, convenient disassembly and low‑cost spare‑part replacement for long‑term commercial operation.
High‑Temperature‑Resistant Integrated Turbine Main Body
Turbine rotor, combustion chamber and exhaust nozzle of this UAV gasoline engine are all cast from premium aviation superalloy. These components continuously tolerate 750 ℃ exhaust temperature under full‑load working conditions without structural deformation or power decay. Streamlined outer casing cuts aerodynamic drag in flight. Symmetric standardized mounting lugs are pre‑reserved to fit most mainstream medium‑large‑size civilian fixed‑wing UAV and RC‑jet airframes without custom mechanical modification.
Civilian Commercial Application Scenarios

Factory R&D & Strict Quality Inspection Flow
The manufacturer maintains complete in‑house micro‑turbine R&D laboratories, CNC intelligent manufacturing workshops and full‑function turbine bench‑test facilities. Every finished SW240Pro UAV gasoline engine must complete six critical inspection procedures before factory dispatch:
- Incoming raw‑material verification: material‑composition analysis plus dimensional calibration for high‑temperature‑alloy rotor, V4‑ECU chip, fuel‑pump hardware and all sealing components.
- Ultra‑high‑speed rotor dynamic‑balancing calibration and real‑time vibration‑magnitude detection.
- Three‑hour uninterrupted full‑load bench test; thrust value, rotational speed, exhaust temperature and fuel‑consumption metrics are logged synchronously.
- Wide‑range temperature‑simulation cold‑start testing for startup‑reliability validation under ‑40℃ ~ +50℃ harsh environmental conditions.
- Full‑kit accessory matching inspection plus functional verification covering wiring harnesses, fuel‑system parts, V4‑ECU and GSU data‑display hardware.
- Finished‑unit anti‑rust protection, anti‑static handling and final packaging quality audit.
Each drone gasoline engine receives a unique independent serial number. All bench‑test logs and manufacturing records are permanently archived to deliver traceable quality assurance for global civilian UAV integrators and resellers.
Frequently Asked Questions
FAQ 1 What fuel and lubrication mixing ratio should I use for SW240Pro UAV gasoline engine? What core advantages does V4 ECU bring?
Answer: This UAV gasoline engine must utilize pure aviation kerosene blended with dedicated turbine lubricating oil at a mixing ratio of 3%‑5%. Any ethanol‑containing fuel is strictly forbidden. Ethanol will generate heavy carbon accumulation inside combustion chambers, clog fuel‑pump pipelines and inflict permanent damage upon high‑temperature turbine rotors. Please clean the fuel filter before every refueling event to stop particulate matter from obstructing fuel circuits. Perform full‑disassembly maintenance strictly complying with the 25‑flight‑hour service cycle.
The upgraded V4 ECU adds complete fault‑code recording, real‑time ambient‑environment monitoring and firmware‑upgrade functions. It can automatically adjust operating parameters for high‑altitude, low‑temperature or high‑temperature working environments and provides richer runtime data feedback for ground‑station monitoring.
FAQ 2 Is SW240Pro’s V4 ECU compatible with third‑party autopilot hardware? What should operators do if fault‑code alarms pop‑up on GSU display terminal?
Answer: The communication interface of V4 ECU works with mainstream civilian‑grade industrial autopilot products available on global markets; matching communication‑protocol documents are supplied free‑of‑charge. When fault‑code alarms appear on the GSU screen, please record the exact fault‑code number first. Then safely shut down the engine and inspect fuel circuits, wiring harness and sensor connections according to official troubleshooting guidelines. If you cannot identify the root cause, send fault‑code records to our technical team for remote diagnostic support. Never force repeated startup under alarm state to avoid secondary component damage.
