Modification of cooling impeller pump in combustion engines driven by electricity

Grzegorz Peczkis

Abstract


This paper presents methods of using an electric powered impeller pump to circulate liquid coolant in a combustion engine.
The proposed impeller pump is driven differently from pumps typically used in combustion engine cooling systems. The
conventional mechanical drive using the mechanical energy produced by the combustion engine is replaced by an electric
motor. This solution is not new, but is being given greater consideration due to the improved power efficiency of the combustion
engine. Power-smart optimum methods of impeller pump regulation are discussed. The guidelines based on the theory of the
impeller pump construction included herein seek to make combustion engine designers more sensitive to issues related to the
design of highly efficient flow systems of impeller pumps. The cooling system pumps which are currently used in combustion
engines often draw on rather unsophisticated structural solutions which are no longer used in any other industry due to their
low efficiency. This is related to the relatively low power consumption of the impeller pump relative to the power output of the
entire engine, as well as to its low cost of manufacture.
