DL275EThe 274cc Two-Cylinder Two-Stroke Piston Engine features a horizontally opposed cylinder configuration, air cooling, and solid-state magneto ignition. With a maximum take-off power of 15 kW at 7,200 rpm and a maximum continuous power of 13.5 kW, it provides a compact power solution for compatible propulsion systems.
The engine incorporates an aluminum crankcase, a drop-forged one-piece crankshaft, cast aluminum alloy pistons, and Nikasil-coated cylinder barrels. Its two diaphragm carburetors are designed for operation in different orientations and are supplied without a choke. The engine supports both pusher and tractor installations, with optional accessories available for specific integration requirements.
Product Description
This 274cc horizontally opposed piston engine uses a two-stroke operating cycle and an air-cooled design. Its 66 mm bore and 40 mm stroke provide a total displacement of 274 cm³ (16.72 cubic inches).
The engine is equipped with a solid-state magneto ignition system and two diaphragm carburetors without a choke. Its crankshaft is drop-forged in a one-piece design and utilizes two split connecting rods with needle bearings. The cylinders are made from cast aluminum alloy with Nikasil-coated barrels.
Rated at 15 kW maximum take-off power and 13.5 kW maximum continuous power at 7,200 rpm, the engine has an approximate dry weight of 7.8 kg in the magneto ignition configuration. It supports pusher and tractor installation layouts.
Optional equipment includes a shielded ignition system, long or short crankshafts, exhaust stacks, a 12 V starter rated at 0.3 kW, and a 28 V, 1,200 W generator. Buyers should confirm the required configuration and compatibility before ordering.
