Sažetak

Abstract Towards the end of 2004, the new ACEA 2004 engine oil specifications for passenger cars have been adopted (ACEA - Association des Constructeurs Européens d'Automobiles). The most significant reasons for introducing new specifications were the Euro 4 exhaust gas emission requirements, causing the introduction of new after treatment devices. With regard to the previous ACEA 2002 specifications, the new ACEA 2004 specifications have introduced the following major changes: · the so far classes A and B for passenger cars were jointed together into a single A/B class · a new class C has been introduced for passenger car engines with after treatment devices · within class E, two categories were cancelled and two new ones introduced The newly established class A/B defines four engine oil categories for passenger car gasoline and diesel engines: A1/B1-04, A3/B3-04, A3/B4-04 and A5/B5-04. With regard to ACEA 2002, there have been no changes regarding oil quality requirements, only the merging of the two classes. The new class C has been introduced for passenger car gasoline and diesel engines with after treatment devices. Within the said class, three engine oil categories have been defined: C1-04, C2-04 and C3-04, with quality matching that of A5/B5 and A3/B4 categories. The most significant element of these categories is the limitation of the engine oil sulphated ash, phosphorus (P) and sulphur (S) content due to its noxious effect on the after treatment devices. In class E, categories E3 and E5 were cancelled, with new ones: E6-04 and E7-04 introduced. Category E6-04 defines oil quality for heavy duty diesel engines with after treatment devices, while it also limits the engine oil sulphated ash, phosphorus (P) and sulphur (S) content, while category E7-04 is in fact an improved former E5 category.
