  • Duct arrangement for an internal combustion engine
    Patent number: 9670820
    Abstract: A duct arrangement for an internal combustion engine comprises an exhaust duct, an inlet duct and a cooling air duct. The exhaust duct is contained within the cooling air duct for substantially its whole length and the cooling air duct is contained within the inlet duct for substantially its whole length, so that in use the cooling air duct provides a barrier to limit heat transfer between gas flowing in the exhaust duct and gas flowing in the inlet duct. The invention avoids the need for separate inlet and exhaust ducts with their attendant disadvantages. The separation of the inlet and exhaust ducts by the cooling air duct allows the inlet air to be kept as cool as possible, as is necessary for efficient engine operation.
