Title:
HIGH EFFICIENCY EIGHT STROKE INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/033567
Kind Code:
A3
Abstract:
A method and a system for operating an eight-stroke internal combustion engine having higher thermal efficiency than a four-stroke engine is disclosed. The strokes comprise intake (FIG 1), compression (FIG 2), combustion for a first power stroke (FIG 3), exhaust (FIG 4), vapor or water injection for a second power stroke (FIG 5), vapor exhaust (FIG 6), vapor injection for a third power stroke (FIG 7), and vapor exhaust (FIG 8). Heat from each exhaust stroke is recovered and recycled to a subsequent stroke. Consequently, an engine with much higher thermal efficiency and thus lower fuel consumption is achieved.
