A heat exchanger of motor vehicle processes a gas flow including combustion exhaust gas. Combustion by-product deposit build-up within the heat exchanger is reduced by maintaining a minimum gas flow velocity within the heat exchanger by reducing heat exchanger total gas flow cross section to locally increase a gas flow velocity.
