Dual Crankshaft Design
The patented dual crankshaft design eliminates the rolling moment and most of the inertia forces and thus strong vibrations typically found in conventional diesel engines.
Aluminium Cylinder Block
The cylinder block of the engine is an Aluminum design. A closed deck with pressed-in dry cast iron cylinder sleeves, this feature optimises servicability and protection.
Automatic Thermomangement System
The Automatic Thermo-Management System manages engine temperatures and further reduces the risk of engine downtime due to overheating.
Bosch Common Rail Fuel System
The Bosch Common Rail fuel system enables quick and direct injection of fuel into the engine cylinders. The sytem delivers greater power and efficiency whilst minimising generation of noise, vibration and smoke.
PTT
The PTT on the Neander Dtorque 50 Outboard Engine features a universal bolting pattern. This enables easy retrofitting where customers wish to keep their existing vessel. This is ideal for fleets with high running hours (i.e. service boards for off shore oil rigs).
Optimised Oil Cooling
Our lower unit features a unique oil cooling system. Within the oil pan, we have included internal fins. This helps us optimise the oil cooling process.
Deep Gear Ratio
With a deep gear ratio, the Dtorque 50 and push higher displacements more efficiently. The deep gear ratio helps reduce loss of power and enables the engine to operate more economically.
