METHOD FOR ESTIMATION OF WASHING ABILITY OF PETROL AND DIESEL FUELS AND THEIR INFLUENCE ON TECHNICAL-ECONOMIC AND ECOLOGICAL CHARACTERISTICS OF ENGINE

摘要

FIELD: chemistry.;SUBSTANCE: invention can be applied for the estimation of a washing ability of petrol and diesel fuel and influence of their washing abilities on technical-economic and ecological (TE) characteristics of an engine (E). The method consists in the preliminarily "pollution" of E with an etalon pollution mixture (EPM) of fuel and oil, which ensures its working in a fixed mode. Upon use of 20-40 l EPM the E is stopped, cooled, dissembled and pollutions (P) are registered. Then E works on the test fuel at standard modes (SM). Its TE characteristics are measured. Then P is registered again. Parameters of SM are given.;EFFECT: increased degree of reliability and objectivity of determining the washing ability of petrol and diesel fuel.;9 cl, 4 tbl
