A new method of investigating piston ring friction in a firing engine is described. Preliminary results are presented for a spark ignition four-stroke 15 cm3 single cylinder engine. Tests were carried out on both a ringed and ringless version of the same engine. From the difference in b.m.e.p. between the engines, the ring friction could be deduced under firing conditions. This friction increased linearly with speed.
