Japanese twin-cylinder, two-stroke engine

Kawasaki 440 Type Two-cylinder two-stroke engine National origin Japan Manufacturer Kawasaki Heavy Industries Manufactured until the early 1980s

The **Kawasaki 440**, also called the **T/A 440**, is a Japanese twin-cylinder, [in-line](/source/Straight_engine), [two-stroke](/source/Two-stroke) engine that was designed for [snowmobiles](/source/Snowmobile) and produced by [Kawasaki Heavy Industries](/source/Kawasaki_Heavy_Industries) until the early 1980s.[1]

The engine was widely adapted for other purposes, including [ultralight aircraft](/source/Ultralight_aircraft) and [Formula 500](/source/Formula_500) automobile racing. Kawasaki did not condone or support the use of the engine in aircraft and it was largely supplanted in this role by the similar purpose-designed [Rotax 377](/source/Rotax_377) aircraft engine.[1]

## Design and development

The engine has two cylinders in an in-line configuration. The single ignition system uses a coil and points. Fuel is metered by a [Mikuni](/source/Mikuni_(company)) 34 mm slide-type [carburetor](/source/Carburetor). Starting is by a [recoil starter](/source/Recoil_starter) system with electric start as an option.[1]

In its aircraft applications the 440 uses an aftermarket reduction drive system to reduce the maximum 5000 rpm to a speed more manageable for propeller use.[1]
