“…A number of studies have been conducted to scientifically measure the quality of engine oils. Inayatullah et al [3] used the technique of acoustic emission to analyze engine oil viscosity. Karpovich et al [4] attempted to develop a universal instrument to measure and control the quality of motor oils.…”

The paper presents a new method of forecasting the durability of piston-rings-cylinder (PRC) liner assembly of the internal combustion engine on the basis of observed changes of physical and chemical properties of engine oil. Methods used so far for the durability evaluation of the PRC group required collecting information about the moments when the assembly reached its boundary state or used kinetic models of wear designed using accelerated research of real objects. In the proposed method, for the evaluation of durability of engine cylinders information gathered form engine oil is used. Course of changes of the proposed index of change intensity of kinematic viscosity at the temperature of 100°C – Cv100 allows for evaluation of the durability of PRC assembly of an IC engine. Obtained value was positively verified using forecasting method related to the technical criteria based on the assessment of the wear intensity.

“…Among the methods used to develop condition monitoring study, the acoustic emission (AE) technology was one of the useful methods in the reciprocating monitoring machine either in term of faults and for running conditions. According to [4], AE method was suitable to be used to the monitor viscosity of engine oil due to the ability of an elastic wave to propagate at the frequency from 0.1 MHz to 1 MHz. Bustles Acoustic techniques have been widely used in the oil industry and can produce effective results.…”

“…However, there is no proving that these practices are the most efficient and economical. Based on [4], most manufacturers recommend a change of engine oil at intervals 5000 km until 10000 km or three months until six months, which is depending ever earlier in a situation of the normal driving condition. Contrasting to this, manufacturers differ in their recommendations of the duration for the change of the engine oil and the other hand, the definition of normal driving condition is not standardized.…”

This research presents the application of Acoustic Emission (AE) sensor to explore the feasibility of an AE signal in the process of monitoring the engine oil viscosity on different condition of mileage during the engine operation. The viscosity experiment was performed in a prior stage of the experiment using four samples of SAE 5W-30 engine oil with the different condition of mileage. On the next occasion, the AE signal was acquired on three cylinders of a four-stroke gasoline engine with a cooling water system which operates using the previous lubricant sample. In this experiment, the AE sensor was bonded on the outside of the engine block and located at the oil filter and oil sump location. It was found that the AE energy value is capable of determining the variant of the engine oil viscosity. The results from this project show that via AE technology proved to be feasible for the development of a real-time lubricant condition monitoring which was believed to be a new technology in the automotive industry.
