“…In the study of Cavalieri et al [20], it was reported that the increasing wear in the internal combustion engine valves had developed a severe issue for valve designers and manufacturers. This wear occurs in the contact between the valve and the valve seat insert under inadequate lubrication.…”

Several types of research have been carried out on using alternative biofuel in internal combustion engines to salvage the depletion of fossil fuels. While most of these studies focused on the emission characteristics and control of global warming, little attention has been given to the corrosion, wear, thermal behaviour, and compatibility of the internal combustion engine materials to biodiesel. Thus, this study focused on the various corrosion and wear mechanisms associated with the internal combustion engine components like piston and cylinder heads, as well as the thermal behaviour efficiencies of the engine after interaction with the biodiesel fuels. The review cut across the wear study of internal combustion engine materials in varying fuel environments. Thermal analysis of different materials applied for internal combustion engines for sustainable fuel media. Corrosion study of various materials employed in the application of ICE engines. Also, the study discusses some significant challenges related to the compatibility of ICE with biodiesel and gaseous fuels. The study’s outcome indicates that an adequate fuel blend with nano additives can help improve the combustion process, emission reduction, and thermal efficiency of the internal combustion engine components. Furthermore, practical design in the internal combustion engine components like pistons will help compatibility with the material in the biodiesel blends, thus reducing wear, corrosion, and other failures associated with the internal combustion engine.

“…It is necessary to have a professional wear tester. Federico J. Cavalieri [40] has studied a valve-seat insert in a 13 L diesel engine with an explosion pressure of 27 kN, and conducted a worn test of 7.184×10 6 impacts on a wear testing machine. P Forsberg [41] also carried out a group of wear tests of a contact pair composed of a valve with a Stellite F sealing surface and an iron base seat insert at an explosion pressure of 20 kN and 7×10 5 impacts.…”

The impact wear properties of two different contact pairs, N80A valve-cast iron seat insert (cast iron group) and N80A valve-clad seat insert (cladding group), were studied in this work. In this paper, an independently designed tribo-tester combined with a depth gauge and corresponding auxiliary devices can record the axial subsidence of the contact pairs during the entire worn process. The results showed that during the 5 × 106 impact test, cast iron groups and cladding groups followed the worn process curve, and all went through the running-in stage and the stable worn stage. However, at each stage, the subsidence of cladding groups was smaller than that of cast iron groups. The roughness meter not only recorded the roughness of all samples before and after the test, but also can obtain the respective subsidence of the samples through the difference between the profiles before and after the test. The results can be mutually corroborated with the axial subsidence measured by the depth gauge. As a result, the roughness of the sealing surfaces of all valve-seat inserts increased significantly after the impact test. The total worn subsidence of the cast iron groups was about 1.61 times that of the cladding groups. The worn morphology was further studied by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). The cast iron group mainly experienced serious adhesive wear and oxidation wear, while the cladding group mainly experienced fatigue wear, oxidative wear and abrasive wear.

“…Although models have their own limitations, one of their advantages is not to have unknown physical factors affecting the results, since the equations representing the model are set by the programmer or user. Computational methods and models such as the FEM and Archard's wear model (or a modified version) have been broadly investigated in the literature [18][19][20][21][22][23], including for specific applications (e.g., gears [24]). Recently, Mukras [25] presented a thorough review of the literature on simulation and prediction of wear.…”

A Closer Look at the Contact Conditions of a Block-on-Flat Wear Experiment

Specific wear rates of tribosystems always rely on the data obtained from wear experiments. Nonetheless, the events taking place during an experiment may often lead to wide variations and low repeatability of the results. In this work, the authors attempt to take a closer look into the dynamic contact conditions of a dry linearly reciprocating block-on-flat wear experiment. The finite element method and Archard’s wear model are used through COMSOL Multiphysics® 5.2a and LiveLink™ for MATLAB® software to model the wear and study the influence of different conditions of the block surface and alignment of the sample. Changes of the geometry of the block and the contact pressure are quantified for several back and forth motions, using an extrapolation scheme in the wear modelling methodology. The tracking of such changes allow a dynamic overview of how the block contact area and the contact pressure distribution change throughout time. The results show how the assumption of a constant contact area and use of a nominal contact pressure in calculating the wear rate in such experiments can be inappropriate, especially in the presence of roughness and misalignments of the block.
