Claim 0:
1. A method of guiding airflow through a portable generator unit, comprising:
rotating a damping cooling fan with a combustion engine;
drawing a first airflow through a first air inlet into a portable generator cabinet;
guiding the first airflow over a cylinder head of the combustion engine, 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 through a second air inlet into the portable generator cabinet, wherein the second airflow is separate from the first airflow and the second air inlet is different from the first air inlet;
guiding the second airflow over a cylinder block of the combustion engine, 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.
