Suzuki has announced that its new DF100 EFI four-stroke engine will available in Europe in the middle of 2008.
The new motor packs a lot of innovative design features to reduce size and weight whilst maximising torque and power. The result is top class performance delivered with fuel efficiency from an engine based on Suzuki's proven in-line four cylinder powerhead (1,950cc).
"We have developed the new DF100 to meet market demand for an engine with excellent power to weight ratio, for a wide range of boats from pleasure to fishing boats, FRP boats to RIBs. Our European customers embrace the strong design and innovation Suzuki brings to the market, and we expect the DF100 to do very well here", comments Mr.Yamamoto, Head of European Marketing Group, Suzuki Motor Corporation.
Two stage gear reduction results in an over all gear ratio of 2.59. This powerful reduction allows the DF100 to turn a larger prop (both in diameter and pitch) for awesome acceleration and exciting top-end speed.
Suzuki's proven multi-point sequential electronic fuel injection is controlled with a powerful 32-bit onboard computer, constantly monitoring a variety of engine sensors for optimum performance in all conditions. The fuel injection system is matched with tuned, long-track intake manifold and race-proven 4-into-2-into-1 exhaust system. Long-track intake manifold contributes to improve performance and torque, especially to the mid-range. The exhaust system dramatically reduces drag on exiting exhaust flow for increased power and performance.
An offset drive shaft allows the engine's centre of gravity to shift forward, giving the DF100 not only better balance on the transom, but also a smaller profile. Suzuki's innovative powerhead design – with dual overhead cams, four-valves-per-cylinder and an oil bathed, self-adjusting chain-drive valve train positioned below the powerhead – allows a smaller cowling and optimum clearance within the motor.
A two-stage mixed camshaft drive system, incorporating both gears and a chain, means smaller diameter cam sprockets can be used, in turn allowing a reduction in valve angles and reducing the size of the cylinder head.
Quietness and reduced vibration at all throttle levels come courtesy of a large volume air silencer, tuned intake track and a specially designed crankshaft, crankcase, engine mount and cowling.
Like all Suzuki fuel-injected 4-stroke outboards, the DF100 meets the EURO emissions standards (EU directive 2003/44/EC) set by the European Parliament and the Council.
