This paper details part of an on-going experimental program to map the operating characteristics of crankshaft bearings. Data from fired engines is essential to validate computer models and enhance understanding of these critical components in the engine system. Oil flow data is particularly valuable when used in conjunction with temperature data, especially at conditions close to the maximum rated engine speed where oil “starvation” effects can be significant.
The results from a 2 litre gasoline engine detailing the oil flow, pressure and temperature show that the most challenging areas of bearing performance are at conditions close to the maximum rated engine speed.
