Abstract
Automobiles have a major role to play in reducing CO_2 emissions as one of the efforts to protect the global environment. Automotive power train engineers have worked on various engineering developments such as the direct injection engine and the variable valve timing for fuel economy improvement or CO_2 reduction. However, in order to meet the increasing demand for CO_2 reduction, it is becoming more important to pursue total efficiency of the whole power train system, not particular technologies in the system. Because hybrid systems have the motor (the battery) as an additional power source to the engine, enabling better energy management of the vehicle compared with conventional technologies, they are capable of optimizing the power train system and that makes hybrid systems important technologies. We are determined to advance the application of this important technology and promote its and penetration into the market as front-running future technology to reduce CO_2.
