Abstract
An apparatus for the suppression of infra red emissions from an engine includes a suppressor body through which pass exhaust gases from the engine, the suppressor body having an inlet means for air which is mixed within the suppressor body with the hot exhaust gases to cool the exhaust gases before final exhaustion, characterised in that at least one sonic or supersonic energy generator is provided to apply within the suppressor body, sonic or supersonic energy to enhance the efficiency of infra red suppression.
Claims11
An apparatus for the suppression of infra red emissions from an engine including a suppressor body through which pass exhaust gases from the engine, the suppressor body having an inlet for air which is mixed within the suppressor with the hot exhaust gases to cool the exhaust gases before final exhaustion, and wherein at least one sonic or supersonic energy generator is provided to apply respectively within the suppressor body, sonic or supersonic energy to enhance the efficiency of infra red suppression.
In combination an engine and an apparatus for the suppression of infra red emissions from the engine wherein the apparatus for the suppression of infra red emissions is an apparatus including a suppressor body through which pass exhaust gases from the engine, the suppressor body having an inlet for air which is mixed within the suppressor with the hot exhaust gases to cool the exhaust gases before final exhaustion, and wherein at least one sonic or supersonic energy generator is provided to apply respectively within the suppressor body, sonic or supersonic energy to enhance the efficiency of infra red suppression.
A vehicle having an engine and an apparatus for the suppression of infra red emissions from the engine, the suppression apparatus including a suppressor body through which pass exhaust gases from the engine, the suppressor body having an inlet for air which is mixed within the suppressor with the hot exhaust gases to cool the exhaust gases before final exhaustion, and wherein at least one sonic or supersonic energy generator is provided to apply respectively within the suppressor body, sonic or supersonic energy to enhance the efficiency of infra red suppression.
A method of enhancing the efficiency of the suppression of infra red emissions from an engine including the steps of providing a suppressor body for the passage of exhaust gases from the engine, the suppressor body having an inlet means for air which is mixed within the suppressor body with the hot exhaust gases to cool the exhaust gases before final exhaustion, characterised in that the method includes applying within the suppressor body, sonic or supersonic energy.
