Abstract
A synchronous dynamometer assembly for applying a load to an engine during at least one portion of the combustion cycle of the engine in a synchronised manner so as to be repeatable each cycle of the engine comprises a dynamometer having a non-inductive load which is applied to the engine during operation to vary the speed of the engine. The non-inductive load is variable by varying the current delivered to it. Crankshaft monitoring means monitors the rotational position of the engine crankshaft, and combustion detection means detects a combustion event in a cylinder of the engine. Control means is operatively connected to the dynamometer for applying the load from the dynamometer to the engine for at least one part of the combustion cycle in real time such that the different loads may be applied to the engine for different parts of the combustion cycle.
