Abstract: Passenger cars produce about 12 % of overall EU GHG emissions (CO2) and transport sector with about 20 % is the second biggest emitter of GHG among all sources. Since 1990, EU has reduced transport emissions by 5 % but the contribution of road transport increased by 26 %. In order to accomplish the Kyoto requirements it is clear that transport emissions should also be reduced. A new decision of EU Commission from Feb 2007 specific the average emission in EU 27 should be 120 g/km by 2012. For several decades the most cost-effective method of reducing CO2 emissions from cars will be to improve fuel efficiency. There are many ways of further improving the fuel efficiency of conventional engines and cars, among them: ignition systems that ensure complete combustion of the fuel available, improved compression at low engine loads, engine and gear friction reduction, six-speed manual transmission, stop-go systems, cylinder deactivation and other. Trybology will help to realize the above improvement by using low friction lubricant, adequate additive and modifying the frictional surface. The paper presents the problems and solutions, which were found.
