SUMMARY:

This paperwork presents a proposal to improve energy efficiency through
parasitic losses reduction on the engine cooling system by means of a novel cooling
strategy to command a two-stage water pump system associated with a variable
electric fan. The fuel consumption benefit assessment was performed on a vehicle with
characteristics on the average of the other 1.0L hatches available on Brazilian market,
and focused on urban driving. For that, it was implemented a methodology that seeks
to minimize absorbed power related to coolant forced circulation but with the
maintenance of heat sink to the environment through increased airflow in the radiator.
In this way, it was possible to obtain a net reduction in parasitic losses, specially at low
speeds, a typical condition of urban routes, by avoiding saturation in the thermal
exchange on the air side of the heat exchanger. The result of this work indicates a
reduction in the power absorbed by the cooling system of up to 80% and shows
expected fuel economy improvement ranging from 1.2% to 1.4% when applied to urban
driving cycles.
