Published September 07, 2000 by AVL List GmbH in Australia
A new hybrid vehicle Toyota Prius has been developed and launched on the European and US market in May 2000. It is a further development of the Japanese '97 model. The new Prius features a 1.5-liter 53 kW high expansion ratio cycle gasoline engine with a 33 kW motor.
For the introduction onto the European and the US market, several modifications have been made to meet customer requirements as well as to comply with the stringent EC Step 4 and California SULEV emission standards.
While hybrid powertrain control strategies efficiently reduce HC emission through rapid catalyst warm up, a new HC adsorber and catalyst system was additionally developed.
A newly developed evaporative emission control system allows to meet the California emission stand powertrain control strategies efficiently reduce HC emission through rapid catalyst warm up, a new HC adsorber and s is growing, in view of global warming prevention and energy saving issues. In recent years, extensive studies have been made to improve fueat at the same time. Through extensive studies and production experiences with Prius, Toyota now considers the hybrid vehicle technology to be one of the best solutions for the near-future next-generation vehicles, compared to other advanced technologies such as electric vehicles and current fuel cell technology.
