Spark ignition engine fuel induction deposits evaluation technique consists of iterative weighing of deposits on a metal insert in the induction system to ascertain the optimum fuel composition

摘要

The spark ignition engine fuel induction deposits evaluation technique comprises weighing the deposits on a metal auxiliary element, in the induction system and kept at a known constant temperature during operation of the engine. This weighing is repeated at other selected temperatures until the maximum-deposition temperature is determined.
