A Study on Fuel Economy and Low Emission Development of LPI HEV (SULEV) to Meet Stringent Emission Regulations

Hybrid vehicles, which have a higher fuel economy and system efficiency than conventional gas only vehicles, has been attracting worldwide attention for its various advantages. These advantages include low emissions of greenhouse gases which mitigates direct or indirect effects on the ozone layer. LPI HEV recently developed by HMC performs with the same output level, torque and fuel economy as conventional gasoline hybrid vehicles by employing the world's first liquid-state-injection system for exclusive use of LPG. In particular, the improved fuel economy of the vehicle is expected to help cope with future regulations relating to environmental protection from exhaust fumes.
