The LPEpower team is most proud to present you this new inline 3 power plant, we consider it to be an epitome of efficiency. 
Compared to its predecesor it is more powerful, smaller and lighter.
SYS I3 has two completely new features:

  • The new crankshaft concept in combination with the Scotch Yoke principle of operation. The first and last crank pieces are constructed from 36 toothed bevel gears and are interconnected with a very rigid longitudinal shaft that prevents the crankshaft from twisting, which in terms greatly improves the torque output.
  • The new camless valvetrain. Sliding yokes directly move the valve rockers - there are no shafts, cams or pushrods in the new camless valvetrain, therefore a huge amount of torsional friction has been eliminated - the new SYS I3 has ONLY eight moving parts! (For comparison: a standard conrod inline 3 with pushrod valvetrain would have arround 17 moving parts)

The maximum speed on 4 bars (60 psi) of pressure is an amazing 1500 rpms, but this engine is not about its max speed, it is all about the torque that comes from such a small package!

The product ships fully assembled and without instructions!
