274cc Two-Cylinder Horizontally Opposed EFI Piston Engine

Product Overview

The 274cc Two-Cylinder Horizontally Opposed EFI Piston Engine features an air-cooled, two-stroke design with an Electronic Fuel Injection (EFI) system and ECU-controlled ignition. It delivers a maximum take-off power of 18 kW at 7,500 rpm and a maximum continuous power of 16.2 kW at the same engine speed.

Designed with an aluminum crankcase, a drop-forged one-piece crankshaft, and Nikasil-coated cylinder barrels, this engine combines a compact two-cylinder configuration with an approximate dry weight of 7 kg. It supports both pusher and tractor installations, subject to the requirements of the target platform.

Product Description

This two-cylinder horizontally opposed piston engine features a total displacement of 274cc, a 66 mm bore, and a 40 mm stroke. Its air-cooled, two-stroke architecture is equipped with an Electronic Fuel Injection system and a computer-controlled 12 V control system.

The engine incorporates an aluminum casting crankcase, a drop-forged one-piece crankshaft, and cast aluminum alloy cylinders with Nikasil-coated barrels. Its variable ECU-controlled ignition system is designed to work with the electronic engine management configuration.

With a maximum take-off power of 18 kW at 7,500 rpm, a maximum continuous power of 16.2 kW, and an approximate dry weight of 7 kg, this engine is suitable for compatible propulsion systems requiring a compact, lightweight power unit. Pusher and tractor installation configurations are supported.

Optional equipment includes a 12 V, 0.4 kW starter set and alternator configurations rated at 14 V, 95 A or 28 V, 45 A, subject to confirmation of the final configuration.

Applications

The 274cc two-cylinder EFI piston engine is designed for compatible power systems requiring a lightweight, air-cooled, two-stroke configuration. Its pusher and tractor installation capability allows it to be considered for different propulsion layouts, subject to the mechanical and operational requirements of the target platform.

Before integration, buyers should confirm mounting dimensions, shaft configuration, fuel requirements, electrical interfaces, cooling conditions, and operating limits with the manufacturer.

Product Advantages

Lightweight Engine Package

With an approximate dry weight of 7 kg, the engine offers a compact power unit for applications with weight constraints.

Electronic Fuel Management

The integrated EFI system and ECU-controlled ignition provide electronic management of fuel delivery and ignition functions.

Horizontally Opposed Configuration

The two-cylinder layout offers an alternative to conventional in-line engine configurations.

Air-Cooled Architecture

The engine uses an air-cooling arrangement rather than a liquid-cooling circuit.

Flexible Installation Layout

Pusher and tractor configurations provide installation options for compatible propulsion platforms.

Optional Electrical Equipment

Starter and alternator configurations can be discussed according to the electrical and integration requirements of the project.

Suitable Buyers

This engine may be relevant to professional buyers evaluating compact two-stroke piston engines, including:

• Engine distributors and importers

• Equipment manufacturers

• Propulsion system integrators

• OEM manufacturers
