Effect of ethanol fuel E85 on lubricant degradation and wear in spark-ignition engines

Timing chain wear investigation methods: Review

“…In another study, Schwarze et al [14] examined the effect of E85 fuel running a gasoline engine using a dynamometer program similar to the previous one. Also, they examined the wear of the chain pins with RNT wear measurement.…”

“…At the same time, the specific load on engines and thus on engine oil has increased significantly due to the downsizing trend of the last decades. In addition to the mechanical and thermal load, the fuels also significantly impact the aging of the lubricating oil and thus the tribology of the engine [11]- [14]; therefore, newly introduced CO 2 -neutral fuels should also be considered in this light.…”

Cold Start with Ethanol-Blend Fuels and Influences on Non-Legislated Emissions of a GDI Flex Fuel Vehicle

“…The use of ethanol interferes with lube oil and causes a quicker degradation of lubricating and cleaning properties [6][7][8].…”

Redução de atrito em motores de combustão interna com o uso do aditivo MoDTC: efeito da diluição de etanol.

“…6 (FERRARESE et al, 2010) Apesar de serem poucos os trabalhos que estudam de forma isolada o efeito da diluição de etanol no desempenho dos óleos lubrificantes, há um ponto em comum na maioria destes estudos que analisam as propriedades físicas dos lubrificantes contaminados: o efeito do etanol na viscosidade dos lubrificantes. Diferentes estudos indicam que a diluição de etanol diminui a viscosidade dos lubrificantes (KHUONG et al, 2016(KHUONG et al, , 2017SCHWARZE et al, 2010;ZHOU et al, 2018) 2015).…”
