Abstract

The tribology of the contact surfaces in a lawn mower internal combustion engine while lubricated with mineral oil contaminated with different percentages of ethanol was studied. The engine ran at about 2000 rpm with no load while the oil reached 80°C. The acceleration signal was integrated twice and obtained the valve lift with high precision, and having the valve acceleration is a first step in determining the systems dynamics characteristics. The most challenging part was the rotating Wheatstone bridge that supported centrifugal forces and failed several times. The piston skirt friction forces and connecting rod bearings showed important values and gave an insight of the wearing process.This is an abstract of a paper presented at the STLE Annual Meeting and Exhibition 2010 (Las Vegas, NV 5/16-20/2010).
