Researchers from Tohoku University (Japan) have developed an analysis method to predict engine wear rate and score. By using it, you can extend the life of the components of any equipment.
Reciprocating engines use reciprocating motion to convert combustion energy. The most serious failures in such engines occur when the oil film on the surface breaks. This leads to increased friction of parts, rapid wear and even wear.
Piston pins and connecting rods require constant lubrication while in motion. However, to verify the effectiveness of the lubrication and determine the degree of wear, lengthy endurance tests are required. Predicting and calculating wear without testing was still considered impossible.
But a group of scientists from the Institute of Fluid Dynamics at Tohoku University led by Professor Jun Ishimoto and Honda Motor Co., Ltd. developed a special multi-stage analysis method.
They not only modeled and predicted tribological properties (a branch of physics about the contact interaction of solids during their relative motion), but also determined the degree of arcuate deformation of the gudgeon pin as the cause of connecting rod seizure.
“With this predictive method, it will be easier to avoid unnecessary damage to car engines and other industrial equipment,” Ishimoto said.
