Research output: Contribution to journalArticlepeer-review


In order improve the performance of a reciprocating engine by reducing friction loss the authors have studied some characteristics of total friction loss of engine, friction of piston assembly and friction cam/follower. The total friction loss is accurately measured by a convenient engine run-out method to examine the change of total friction mean effective pressure with engine speed, load rate and oil temperature in a fired and braked engine.
