Process to Deliver Value to Society
“Contributing to a better world by creating value together with a vision for the future”
To continue as a company that has earned the trust and meets the expectations of people all over the world, DENSO helps to deliver the convenience and joy of cars on a global basis while aiming to realize its Long-term Policy of “preserving the Earth’s environment” and “creating a society that ensures security and safety.”
To this end, DENSO has been sharing among all its employees the DENSO Spirit passed down since its establishment and contributing to the creation of a better society by leveraging its strengths in unique R&D, Monozukuri and Hitozukurii (human resource development).
This viewpoint of “Business to Society” has led to not only the sustainable growth of society but also the improvement of DENSO’s corporate value, thereby supporting the sustainable growth of the Company.
Past Initiatives and Achievements
DENSO has grown together with society by constantly providing new value while repeatedly engaging in processes geared toward sustainable growth. This section introduces examples of initiatives we have been engaging in and the results we have achieved thus far based on the DENSO Group Long-term Policy 2020 and with a particular emphasis on “preserving the Earth’s environment” and “creating a society that ensures security and safety,” which are concepts that we are currently focusing our efforts on.
Common Rail Systems That Support Cleaner Diesel Engines
A diesel common rail system is a fuel injector system for diesel engines in which highly compressed fuel is stored in an accumulator called a common rail, and then timely sprayed into each cylinder in an appropriate amount at high pressure through electronically controlled injectors. Using high fuel injection pressure atomizes the fuel into finer droplets, which improves fuel ignition and combustion efficiency, resulting in increased fuel economy and cleaner exhaust emissions.
Exhaust emission standards are becoming increasingly stringent around the world, requiring higher precision control of fuel injection quantity, timing, and pressure. Against this backdrop, DENSO announced a new diesel common rail system in June 2013 with the world’s highest* injection pressure of 2,500 bar. The new system can increase fuel efficiency by 3% while also reducing particulate matter by 50% and nitrogen oxides (NOx) by up to 8% compared with DENSO’s previous generation system (maximum value: based on DENSO research). Cars manufactured by Volvo are among some of the vehicles equipped with the 2,500 bar system combined with intelligent-Accuracy Refinement Technology (i-ART), a system that provides optimum control of the fuel injection quantity and the timing of each injector.
Since 2012, the DENSO common rail system has been used in Mazda Motor Corporation’s SKYACTIV technology to support the environmental performance of its diesel-powered models, including the Mazda CX-5, Atenza, and Demio.

Development of Products for the Next Generation of Eco Cars—Fuel Cell Vehicles
DENSO is moving forward with the development of technologies that contribute to the promotion of vehicles powered by fuel cells, which use hydrogen to generate electricity.
In fiscal 2015, DENSO developed various products for fuel cell vehicles, such as a fuel cell monitoring unit, high-pressure hydrogen sensors, and a hydrogen charging ECU. In addition, DENSO-developed products have been installed in the MIRAI, the fuel cell vehicle manufactured by Toyota Motor Corporation. These products include high-voltage power system components, such as a power control unit and fuel cell boost converter, as well as cooling system parts, such as a radiator and cooling pump, that greatly improve cooling performance.
Going forward, DENSO shall continue to utilize technology developed for hybrid, gasoline, and diesel vehicles in order to provide products that contribute to improving the reliability and performance of fuel cell vehicles while at the same time reducing the cost of such vehicles.
Commencement of Large-Scale Verification Tests for the Practical Application of Bio-Fuel from Microalgae
To promote the practical application of bio-fuel, DENSO has constructed a 20,000m2 microalgae (Pseudochoricystis ellipsoidea*) cultivation and verification facility in Amakusa, Kumamoto. The facility commenced operations in April 2016 and is one of the largest of its kind in Japan. By fiscal 2019, DENSO aims to establish elemental technologies geared toward the practical application of bio-fuel extracted from algae.
* Pseudochoricystis ellipsoidea is oil-producing microalgae patented by DENSO that are fast-growing, vigorous, and easy to cultivate.
Security and Safety
Development of Vision Sensor and Millimeter-wave Radar Sensor That Help Prevent Collisions
The need for safety products such as those that help prevent collisions is rising, and it is anticipated that the use of such products will rapidly become widespread in the future. DENSO has developed a vision sensor and a millimeter-wave radar sensor that can detect not only vehicles but also pedestrians. By combining the functions of these two sensors, the special features of both sensors can be leveraged and objects in front of and behind vehicles can be detected in a more prompt and accurate manner. These sensors are being used in Toyota Safety Sense P, Toyota Motor Corporation’s pre-collision safety package, and have been installed in new Prius and Land Cruiser models.
DENSO aims to expand the scope of collision prevention by developing products that are able to detect bicycles and nighttime pedestrians.
Traceability Services Created from QR Codes and Smartphones
Since Denso Wave Inc. (then DENSO Corporation’s Business Division) first developed QR codes in 1994, these codes have become popular throughout the world and continued to evolve, helping to conserve time and resources for companies in a wide range of industries.
Recently, Denso Wave launched and commenced sales of “Q-revo trace,” a service that visualizes distribution from the producer to the consumer using a tracing function that leverages QR code and cloud technologies. With this service, users can easily confirm via their smartphone who produced a product, when a product was shipped, and how a product was delivered. In doing so, Q-revo trace allows reliable products to be delivered to consumers with peace of mind.
Launch of Global Traffic Safety Education Program with Mitsui Sumitomo Insurance
In addition to the traffic safety activities it conducts in countries and regions around the world, DENSO has launched a global traffic safety education program in collaboration with Mitsui Sumitomo Insurance Co., Ltd. The program has commenced visiting lectures in Thailand, China, and Japan, and will be expanded to other areas in the future.
Traffic safety is a theme that is shared around the world. DENSO will continue activities to raise awareness for traffic safety in accordance with the issues that are facing each country and region. These activities place importance on raising the awareness of not only drivers but also pedestrians and other vulnerable road users. By improving etiquette and standards related to traffic safety through the implementation of visiting lectures around the world, DENSO will contribute to the realization of a society without traffic accidents.
