Neander solution

The central aspect of Neander technology is a unique innovation with which the complex requirements of modern high performance diesel engines can be completely fulfilled: the double crankshaft.

This principle, in which the pistons act on two opposing crankshafts via two connecting rods, results in almost vibration-free running.

This enables the construction of powerful, compact lightweight diesel engines with only 1 or 2 cylinders. This opens up a large number of large new markets for the diesel engine!

The double crankshaft has the following characteristics:

• Compensation of all rotating inertial forces
• Compensation of all 1st order oscillating forces (torque compensation)
• No reactive effect due to torque impulses on the exterior of the engine are detectable
• No torque due to inertial effect and its phase difference from compensation measures
• Very low friction losses from the guidance of the piston by the connecting rod (the lateral guiding force of the piston is effected by the connection rod)
• Use of large single swept volumes with better thermodynamic efficiency

The potential power range of this engine concept ranges from a 400 ccm single cylinder to a 1.4 litre two-cylinder engine with a power range from 12 hp to 110 hp and a torque from 25 Nm to 220 Nm.
