To meet increasingly stringent environmental regulations around the world, there is a need to efficiently convert fuel into kinetic energy, and reduce emissions of gases such as CO2.We have developed engine technologies such as direct injection and valve timing control that greatly increase the efficiency of internal combustion engines. In addition, we use simulation and analysis technologies to continually refine our components, improve engine thermal efficiency, and produce clean engines with a reduced environmental burden.
We are developing technologies that reduce CO2 emissions by improving engine thermal efficiency. In addition to fuel injectors with outstanding performance, our technologies also provide optimal drive control. Our direct injection gasoline (DIG) technology is enabled by fuel pumps that provide precise fuel injection control. Furthermore, our valve timing control (VTC) technology continuously varies the intake and exhaust valve timing based on the driving situation such as the engine’s revolution rate, temperature, and load. Through this wide range of technology, we can stabilize engine combustion and reduce harmful emission gases such as nitrogen oxides (NOx).
Reduction in the amount of particulate matter in emission gases has been achieved through the utilization of computer simulations and analysis technologies. In an engine, a fuel-air mixture is formed inside the combustion chamber from fuel spray injected by the injector and air flowing in from the intake pipe. Our technology homogenizes the fuel-air mixture by simulation and analysis of this phenomenon, and aims to significantly reduce particulate matter by optimizing combustion through simulation analysis of the injector nozzle tip and the internal fuel flow.
