Neander solution

The double crankshaft

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:

  • Almost all free mass forces (first and second order) have been eliminated
  • Complete balancing of moments (no roll-torque!)
  • Reduced friction due to reduced side forces (piston group)


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.
