OVER8™ is a heat management system that reduces CO2 emissions and fuel consumption by over 8% at a fraction of the cost of hybrids.

OVER8™ consists of a number of individual modules that can be combined in various ways. Here are some benefits at a glance:
  • Reduction of CO2 emissions and fuel consumption y over 8% (during Certification tests, and Real world driving)
  • Lower NOx emissions during certification testing and real world driving
  • Less CO emissions
  • Improves drivability and vehicle safety
  • More affordable than mass produced technologies like hybrid engines
  • Enables longer oil change intervals
    Reduces engine wear
  • Increases engine performance
  • Improves cabin warm up
  • Applicable for all types of internal combustion engines, including diesel, petrol, LPG, CNG, etc.
  • Suitable for any powertrain configuration such as hybrid, manual or automatic transmission

Examples of OVER8™ modules

Inner Insulation of Oil Gallery

A novel insulation inside of the engine oil galleries ensures that the engine oil reaches the engine bearings with the optimal temperature. This reduces engine friction during warm up and during normal operation. By inserting pre-fabricated inserts with a flow optimised shape into the oil galleries, the hydraulic resistance is reduced so that a smaller oil pump can be used. When the engine works harder the oil that cools the piston and bearings is also kept colder through the insulation. Benefits at a glance:

  • Keeps oil warmer during cold start
  • Improves engine cooling during high loads and speeds
  • Reduces hydraulic loss of engine gallery
  • Very low cost
  • Easy to install

Cylinder Heat Transfer Control (Details Confidential)

Benefits at a glance:

  • Controls the heat transfer through the cylinder by a factor between 1 and 100
  • Several stages are possible
  • No package space required
  • No extra weight
  • Very low cost

Split Lubrication Circuit

Benefits at a glance:

  • Separates lubrication circuit in a hot and a cold part
  • The hot part feeds the bottom end including the crankshaft during cold start and warm up to reduce friction
  • The cold part feeds the valve train to avoid mixed lubrication
  • The turbo charger can be controlled depending on the actual demand, e.g.
    – Warm oil during cold start for higher engine performance, safety and driveability
    – Cold oil during hot engine operation to reduce oil leakage into the intake to reduce emissions including particles and Hydro Carbons
