“…The enhanced performance from EC-CMC could be from the transformation of the sliding motion into rolling. The results are similar to those of previous studies, 25,27 in that the inclusion of reinforcing fibers considerably enhances the wear resistance of polyimide (PI) subjected to oil lubrication.…”

“…Figure 4(a) and (b) shows the friction coefficients and wear rate of the various lubricants under load of 80 N and temperature of 75°C at frequency of 5Hz. Due to the excellent viscosity index results under corn and sunflower oil, as well as previous recommendations, 25 an additive concentration of 1wt% EC-CMC was adopted. The base sunflower oil lubricant average COF was 0.080, while base CO was 0.087 as illustrated in Figure 4(a).…”

An investigation on lubricating oil rheological behavior and tribological effect on sliding contact was conducted. The study employed organic polymer Eichhornia Crassipes carboxymethyl cellulose (EC-CMC) polymer as additive in corn oil (CO) and sunflower oil (SFO). The experiment was performed using high frequency reciprocating rig (HFRR). Analysis on viscosity behavior was done with three samples of EC-CMC concentration (0.5 wt.%, 1 wt.%, and 1.5 wt.%) under 100 ml volume of base CO and SFO samples. Rheological studies on the polymer concentrations show good results with 0.5 wt.%, 1 wt.%, and 1.5 wt.%, but indicated optimal on 1 wt.% EC-CMC especially from temperature beyond 100°C for the two selected lubricants. Under friction and wear analysis, the test was conducted using 1 wt.% EC-CMC. The base lubricants CO and SFO yielded coefficient of friction and wear scar diameter of 0.087, 11.2 × 10−6 mm3/N/m and 0.080, 10.5 × 10−6 mm3/N/m, respectively. During the testing, the use of 1 wt.% EC-CMC blended SFO gives lower coefficient of friction than CO both at base state and inclusion with additive. This yielded COF reduction by 22.5% and 13.8% for 1 wt.% EC-CMC + SFO and 1 wt.% EC-CMC + CO, respectively, but gives better reduction under SAE-5W-30. The analysis concluded that application of 1 wt.% concentration of EC-CMC in base oil lubricant for both SFO and CO significantly enhanced the properties. The utilization of this sustainable product certainly will contribute in solving global pollution challenges.

“…The observations are in consonant with previous reports. 13,14 The energy-dispersive X-ray (EDX) analysis is shown in Table 1, revealing the presence of many elements in EC-CMC while only carbon and fluorine whereas the Zr element was from the coating process. The data from the earlier study was like the elements mentioned.…”

Bio-based lubricants are becoming more prevalent in the lubrication sector to substitute the traditional petroleum based. In the current study, jatropha oil was used as the base lubricant with polytetrafluoroethylene (PTFE) and organic Eichhornia crassipes-carboxymethylcellulose (EC-CMC) polymers as additives. The research employed a sensitive reciprocating apparatus to examine the tribological responsiveness of the formulation on AISI 52100 steel material in terms of coefficient of friction (COF), wear rate, wear scar diameter, and surface roughness (Ra). Polymeric and Fourier transform infrared spectroscopy studies were conducted on the formulations. The findings indicate that both additives in jatropha in concentrations produced higher COF than unmodified jatropha oil at 100 and 250 r/min under low load (15 N), but improved performance under higher load (35 N). Under wear rate examination, the formulations demonstrated a slight reduction under higher working conditions; however, the 0.5 wt% EC-CMC blended sample performed poorly in terms of both COF and wear rate. In the research, 0.4 wt% PTFE and 0.3 wt% EC-CMC produced the best outcomes for their respective categories. The nano lubricant exhibited remarkable performance when tested under more demanding working conditions (500 r/min and 45 N) but performed better when 0.4 wt% PTFE was utilized, which is comparable to the reference commercial shell lubricant used. The ability of the nano lubricants to penetrate and generate some films at the sliding contact during operation shows their enhanced performance at higher operating conditions, which was supported by the results of the energy-dispersive X-ray study.

“…Palm oil and rapeseed oil are examples of edible oils. Non-edible oils are those that are not suitable for human consumption (e.g., Polanga and mahua oil) (Thirugnanasambantham et al, 2020;Singh et al, 2021a;Tasneem et al, 2022;Opia et al, 2022;Shahabuddin et al, 2022). Akintunde et al (2021) transesterified sandbox oil into biodiesel and studied the impact on diesel engine performance and combustion and came to the conclusion that it's a realistic solution for lowering emissions.…”

Lubrication is necessary to minimise the frictional impact created during the running of a vehicle since it increases wear and friction among the parts in contact. Wear and friction shorten the component's life, decrease its dependability, and raise maintenance costs. The current study uses a tribo tester to examine the friction and wear properties of rapeseed biodiesel at fixed parameters. The investigated lubricants included B0 (diesel), B100 (biodiesel), and four distinct blends of biodiesel: B15, B30, B45, and B60. Analysis was done for one hour at ambient temperature with a standard load of 140 N at a speed of 1000 rpm. The outcome showed that as the concentration of biodiesel augmented, friction and wear scar get reduced. The aluminium pin wear in B100 appeared 16% less than that in diesel. Also, the presence of esters and fatty acids during Fourier transform infrared analysis of biodiesel contributes more to its possibilities as a lubricant.
