Alternative engine in dynamic regime: Valve clearances; Studio del gioco delle valvole di un motore alternativo in regime dinamico

Abstract

Alternative engines employing intake and exhaust valves usually present difficulties with regard to the control of valve clearances. Presently, the control is carried out when the engine is shut down and cold; and this control thus represents a significant amount of engine downtime. This paper presents a technique which reduces downtime and, above all, allows the valve control operation to be performed with the engine running and in the thermal regime. During performance tests on a prototype, it was possible to control the valves while contemporaneously modifying the engine operating conditions, i.e., temperature and speed.
