Turbocharged Gasoline Aero Piston Engine with 300 kW to 1,000 kW Power Range, 2

The L/V family represents a comprehensive range of turbocharged gasoline aviation piston engines, featuring inline L-series (3/4/5-cylinder) and V6 series (6-cylinder V-layout) configurations. The power spectrum covers continuous output from 300 kW to 1,000 kW, targeting high-performance manned aerial vehicles. All models utilize aviation gasoline fuel and share a unified 2,000-hour TBO cycle. At 4,000 m altitude, power loss is controlled within 10%-15% under turbo compensation.

Every unit is equipped with large-size twin turbochargers for forced air intake compensation. Unlike naturally aspirated engines that suffer severe power attenuation at high elevations, this series limits power loss to merely 10%-15% at 4,000 m. Sufficient thrust is retained for steep climbing, high-speed cruise and heavy-load takeoff under plateau and mountainous operating environments.

The full operating band spans 5,500-8,000 rpm for the high-performance variants. Massive transient power reserve is built into the hardware, delivering rapid throttle response during vertical climb, acceleration and gust resistance, perfectly matching the dynamic power demand of high-speed manned aerial vehicles.

Inline 3/4/5-cylinder and V6 units share identical base mechanical architecture. Engineers adjust cylinder quantity, turbocharger specifications and ECU calibration only to cover the full power bandwidth from 300 kW to 1,000 kW. High part interchangeability lowers spare part stocking pressure and operator training cost.

Integrated thin-wall cast aluminum cylinder blocks eliminate redundant structural weight. Optimized lightweight treatment is applied on upgraded models such as L401B to cut mass without sacrificing structural rigidity. The flagship V601-379 achieves a peak power-to-weight ratio of 6.1 kW/kg, far exceeding traditional V-type aviation piston engines of equivalent power output. The compact footprint simplifies installation inside narrow eVTOL and aircraft nacelles, maximizing available payload and fuel capacity.

All models adopt a consistent 2,000-hour Time-Between-Overhaul cycle, eliminating differentiated overhaul scheduling for mixed fleets. Core mechanical and electrical components are cross-compatible across the lineup to streamline after-sales support.

Multi-point aviation gasoline EFI system delivers smooth, lag-free throttle modulation. No pre-heating procedure is required before startup, unlike heavy-fuel compression ignition engines. Operation remains stable under frequent takeoff, landing and speed adjustment cycles typical for manned aircraft.

• Industry Top-Tier Lightweight & Power-to-Weight Performance: Lightened casting technology cuts unit mass significantly while boosting power density. The outstanding kW/kg rating reduces empty aircraft weight, directly lifting passenger capacity, cargo load and maximum flight range for eVTOL and fixed-wing platforms.
• Complete Full-Band Power Product Matrix: The lineup provides seamless power coverage from 300 kW entry-level units up to the 1,000 kW flagship V6 model. Operators can source all required power grades from a single product family.
• Superior High-Altitude Operation Adaptability: Turbo forced induction offsets thin air at high elevations, delivering steady climbing power for mountain tourist routes and plateau commuter flights without obvious performance degradation.
• Generous Peak Power Safety Margin: Each engine's hardware maximum power capacity is substantially higher than its rated continuous output. Extra power reserve acts as a critical safety buffer during emergency scenarios.
• Simplified Ground Operation & Maintenance Workflow: Elimination of heavy-fuel cold preheating systems shortens pre-flight preparation time. Onboard ECU integrated self-diagnosis functions quickly pinpoint abnormal components.

3-6 seat intercity tilt-rotor air taxis, scenic sightseeing composite-wing manned carriers, and amphibious water-land passenger aerial vehicles. Recommended models: L401B, L501 and V601 series, leveraging lightweight high power-to-weight design to maximize passenger load and flight endurance.

Plateau mountain sightseeing aircraft, private sport planes, flight training trainers, light seaplanes and island short-haul commuter aircraft. Recommended models: L301, L401 and L501 mid-power inline variants (300-600 kW continuous output).

Performance racing aircraft, high-speed target drones and experimental high-performance flight vehicles rely on the series' high-rev instant acceleration and massive peak power reserve for extreme flight speed requirements.

6+ seat long-distance intercity commuter aircraft and large amphibious general aviation vessels select the flagship V601-379 unit to deliver sufficient thrust for heavy payload and steep climb missions.
