Parameters > Lubricant Consumption
Lubricant oil is used in engines to reduce friction and to cool down specific components. Lube oil enters the combustion chamber and is oxidized during combustion, before it is exhausted to the atmosphere. The hydrocarbon composition of lube oil means that it unintentionally contributes to the CO2 emissions without taking part to the energy consumption of road transport. The only exception is two-stroke engines where the lube-oil is intentionally delivered to the cylinder and part of the lube oil could be used to deliver some energy to the engine (especially in older two-stroke engines).With this form the user can view and edit the parameters used for calculating the lubricant consumption in each vehicle category.
