It has been demonstrated that a small turbocharged, common rail diesel engine suits very well the commercial ouboard segment of 40 hp to 70 hp. One key enabler for the use of a small inline, two cylinder diesel engine is the dual crankshaft arrangement which eliminates greatly inertia forces and, most importantly, roll torque at the engine mounting point at the transom of a boat. The high torque reserve of the Neander engine allows the use of large propellers which make the engine an ideal propulsion package for heavier boats. The higher initial cost of the more complex engine architecture and peripherals compared to a commonly used gasoline engine will be amortized rather quickly under commercial operating conditions. The new dual crankshaft concept for a small two cylinder diesel engine, which makes the engine run with minimal vibration footprint will certainly open additional application fields besides marine in the future.
