RESULTS OF WASTE PARTIALLY SYNTHETIC AND SYNTHETIC MOTOR OILS
The article presents the results of studies fulfilled partially synthetic and synthetic oils in engines working at concentrations aging products using photometric method cal control and anti-wear properties. To determine the limit state reflected bot oils perform statistical analysis of the results of photometry. This allows it possible to build distribution curves of the degree of contamination of waste synthetic and partially synthetic motor oils on the number of samples. Also asked to assess the state of folder ating elements of the engine oil system at a concentration of insoluble aging products and the state of the engine cylinder and piston group on volatility used oil bath thermostat regulated at a temperature of 180 °C. Control of waste oils was carried out when developing their inst ruktivnyh terms recommended by the engine manufacturers. The accumulated statistical cal data on the optical properties of the oils, their viscosity and concentration of total soluble and nonproliferation soluble impurities allowed to construct a graph of the distribution of these indicators on the amount of the test machine, and is determined by the expectation values of these parameters under which a replacement of oil for most cars.
