Ultimate Fuel Consumption Performance

To become a world leader in the provision of products that conserve energy and contribute to the reduction of CO₂ emissions, DENSO will develop technologies that help improve the fuel efficiency of all of its products, including engine control technologies. We will also promote the development of new technologies and renewable energy, such as biofuels and hydrogen.

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.

In these ways, we will realize energy management that connects vehicles with the greater society, centered on driving systems and thermal systems, thereby contributing to a carbon-neutral society.

In addition to providing electrification technologies for HEVs, PHEVs, BEVs, and other passenger cars, we are developing such technologies to support all types of electric mobility, including　everything from automated conveyors in plants and warehouses, compact vehicles, and two-wheeled vehicles in the domain of compact electrification, to commercial vehicles, agricultural construction equipment, and aircraft in the domain of large-scale electrification. In particular, we are developing electric motors (e-motors) for electric vertical take-off and landing (eVTOL) aircraft, which solve the issues of traffic congestion in cities and the resulting CO₂ emissions as well as the need for high-speed transportation networks that enable travel for the shortest possible distance and are connected to suburban and sparsely populated areas that are distant from trunk communication routes. By doing so, we have added to our product lineup e-motors that can be applied to two types of propulsion: propellers and jets. Our newly developed e-motors are both compact and lightweight to an extent that exceeds conventional standards, thanks to the use of lightweight materials and enhanced cooling performance.
We will apply technologies cultivated for vehicles in the automotive industry to aircraft, including electrification technologies and technologies for the mass production of high-quality products. At the same time, we will apply technologies honed in the aircraft business to the automotive industry. In this way, DENSO will contribute to the realization of a sustainable mobility society.
