Abstract
An apparatus and method for cleaning the intake system of an internal combustion engine, such as an automobile engine, employs intake manifold vacuum of the running engine to ingest and atomize a liquid cleaner using a bleed of ambient air. Atomizing of the liquid cleaner provides better dispersion of the cleaner to surfaces of the intake system of the engine, and prevents puddling of the liquid in low spots of the intake system.
