Claim 10:
11. A method of air-cooling a portable generator unit, comprising:
drawing a first airflow through a first air inlet into a portable generator cabinet;
air-cooling a cylinder head of a combustion engine with the first airflow, wherein the first airflow draws heat from the cylinder head to cool the portable generator unit;
receiving, by a first airflow passage, the first airflow from the cylinder head of the combustion engine;
guiding the first airflow through an air outflow duct;
drawing a second airflow, separate from the first airflow, through a second air inlet that is different from the first air inlet, into the portable generator cabinet;
air-cooling a cylinder block of the combustion engine with a second airflow, wherein the second airflow draws heat from the cylinder block to cool the portable generator unit;
receiving, by a second airflow passage, the second airflow;
guiding the second airflow over an alternator and through the air outflow duct; and
maintaining, by an airflow distributor, separation of the first airflow and the second airflow through the air outflow duct, the first airflow passage in communication with a first airflow outlet and the second airflow passage in communication with a second airflow outlet.
