548cc Four-Cylinder 50 HP Two-Stroke Piston Engine

Product Description

This four-cylinder, horizontally opposed piston engine features a 548cc displacement and a two-stroke operating cycle. Its air-cooled design uses cast aluminum alloy cylinders with Nikasil-coated barrels, while the aluminum crankcase provides a lightweight structural foundation.

The engine is equipped with a solid-state magneto ignition system and four diaphragm carburetors designed for operation in different orientations. Its forged, seven-piece crankshaft and ground, cast aluminum alloy pistons contribute to its mechanical design.

With a maximum take-off power of 37 kW (50 HP) at 7,500 rpm and a maximum continuous power rating of 33.3 kW as specified by the manufacturer, the engine is suitable for compatible pusher and tractor installations. Buyers can also inquire about optional accessories, including a shielded ignition system, exhaust stacks, a 24 V starter, and a generator.

Applications

The engine supports compatible power system designs requiring a four-cylinder, air-cooled, two-stroke configuration. Its pusher and tractor installation capability allows integration into different propulsion layouts, subject to the requirements of the target platform.

Potential applications should be confirmed with the manufacturer based on the intended equipment, installation dimensions, cooling conditions, fuel requirements, and operating environment.

Product Advantages

Compact Four-Cylinder Design

The horizontally opposed configuration provides an alternative to conventional in-line engine layouts.

Air-Cooled Engine Architecture

The cooling system does not rely on a liquid-cooling circuit, simplifying the overall cooling arrangement.

Carburetor-Based Fuel Delivery

Four diaphragm carburetors provide the specified fuel delivery configuration. The engine should not be described as EFI-equipped unless a separate model specification confirms electronic fuel injection.

Flexible Installation Options

Pusher and tractor configurations allow the engine to be considered for different compatible propulsion layouts.

Configurable Accessories

Optional starter, ignition shielding, exhaust components, and generator equipment can be discussed according to project requirements.

Customization / OEM / ODM

For project-based procurement, buyers can contact our team to confirm engine configuration, installation requirements, accessory availability, technical documentation, and compatibility with their target platform.

Optional equipment and configuration requests are subject to manufacturer confirmation. Please provide your intended application, required power output, installation layout, and expected order quantity when requesting a quotation.

FAQ

Q1: What type of engine is this?

It is a 548cc, four-cylinder, horizontally opposed, air-cooled, two-stroke piston engine with solid-state magneto ignition.

Q2: What is the maximum power output?

The stated maximum take-off power is 37 kW (50 HP) at 7,500 rpm. The supplied specification lists maximum continuous power as 33.3 kW and 50 HP; this discrepancy should be confirmed with the manufacturer.

Q3: What fuel does the engine use?

The supplied specifications list AVGAS 100LL or 90 RON gasoline, mixed with suitable oil at a ratio of 1:25 or 1:50 when using synthetic oil. Confirm the applicable fuel and lubrication requirements before operation.

Q4: Does the engine use electronic fuel injection?

No electronic fuel injection system is identified in the current specifications. The listed fuel delivery system consists of four diaphragm carburetors.

Q5: What is the dry weight of the engine?

The approximate dry weight is 18.3 kg. Additional cylinder heat sinks add approximately 1.2 kg.

Q6: Can the engine be installed in pusher and tractor configurations?

Yes. The supplied product description specifies suitability for both pusher and tractor installations. Final compatibility depends on the target platform and installation requirements.

Q7: What optional equipment is available?

Listed options include a shielded ignition system, exhaust stacks, a 24 V, 0.5 kW starter, and a generator. Availability and generator specifications should be confirmed.

Q8: How can I request a quotation?
