dc.description.abstract |
Hybrid vehicles seem to be, for the foreseeable future, the only way forward in lowering CO2
emissions of private transport. The objective of this project is to analyze the two forms of
hybridization: The series and the parallel hybrids, and compare their advantages and
disadvantages.
On sale today, the Toyota Pruis, a parallel hybrid, is the best selling hybrid. Its main
competitor is the Honda Civic Hybrid, recognized as a series hybrid. These two examples
were studied and compared in different everyday driving situations.
The Prius has the better fuel economy and emissions. However, for its lower drag coefficient,
less powerful petrol engine and more powerful electric motor, it only gains minimal
drop in CO2 emissions over the Civic. Improvements to the Civic should include emission
free operation at low speeds. A hybrid system for the Prius should be developed that has
lower weight; at present, it has two electric motors and two batteries.
Further analysis should still be carried out in an attempt to improve hybrid vehicles further.
Performance at low speeds (<40km/h) should be investigated further, concentrating on
prolonged periods of city driving. |
