Abstract
Keywords: New type of additive, Environment protection, Increased engine life, Lifelong lubrication without oil change
The requirement of our age is to improve the efficiency of the energy consumption and to reduce the quantity of the environment poisoning materials. The I.C. engines are the primary key to solve this problem.
The new type of additive is an organic compound, chemically bound to metal surface, has positive and negative charges, creates 1 m thick multimolecular layers on the rubbing surfaces. The new additive is multifunctional: i. e. friction reducer, antiwear, extreme pressure, antioxidant, rust inhibitor and it is effective without pour point depressant and viscosity index improver. The necessary concentration in the oil ranges between 1/51/ 10 of the usual additives.
Tests were made on test bench and on road with cars, trucks and buses in Hungary, UK, US. The wear was reduced by 50%, the fuel consumption by 2025%, the oil consumption by 55%, the harmful emission by 70%, the compression of the cylinders were restored in the used engines nearly to the original value. The floating particles concentration in the oil reduced from 0,015% to 0,002%.
The advantageous test data opened the way to exploring the possibility of increased oil change cycles. These tests were made with intercity buses. The 5 buses are now over 700 000 km running without changing the oil. The 5 favorable properties with the new type of additive remained unchanged.
