Ultimate Fuel Consumption Performance

Basic Stance

DENSO develops technologies that help improve fuel consumption and leads the world in all products including engine control technologies that reduce CO2 emissions from all new cars sold each year by half. We also promote the development of new technologies and renewable energy, such as bio-fuels and hydrogen.

Specific Initiatives

Product use represents the stage with the highest CO2 emissions in the automobile life cycle. Thus, to help prevent global warming, it is important to increase fuel efficiency through the use of lightweight designs in automotive parts and ensure high combustion efficiency. In DENSO-related product areas, we are promoting advanced “improvements in fuel efficiency and less power consumption” through control that links systems installed in vehicles, such as engine management systems, car air-conditioners, and safety equipment.

In addition to improving fuel efficiency and reducing power consumption, which minimizes energy loss, we are implementing energy management initiatives for the efficient use of energy pertaining to mechanisms for the recovery and reuse of heat energy emitted from cars and kinetic energy lost when decelerating. Furthermore, we are working to popularize the electrification of vehicles, beginning with hybrid vehicles and fuel cell vehicles that are suited for making use of such energy-management mechanisms.
