Abstract
A pollution control method and related devices for cyclical internal combustion engines having a separate combustion chamber (1), wherein the compression chamber, the combustion chamber (1) and the expansion chamber (16) consist of three separate and entirely self-contained portions. During low-power operation, e.g. in urban traffic, the fuel injector (6) is no longer controlled during filling of the combustion chamber, whereby the combustion chamber is filled with high-temperature pure compressed air at each cycle. A small amount of additional air from an outer tank (23) for storing highly pressurized air at room temperature is fed into the combustion chamber substantially after the intake of compressed air from the engine compressor, and heated as it contacts the hot compressed air already present in the combustion chamber (1), whereafter it expands and increases the starting pressure to enable effective work to be produced during expansion.
