Hino goes beyond researching and developing breakthroughs in basic truck and bus performance – it actively studies how to make its vehicles better for people and the environment in areas such as reduced emissions, quieter operations and improved levels of safety and comfort.
Hino has already implemented the Hybrid Inverter-controlled Motor & Retarder (HIMR) system, which uses a diesel and electric motor. This system has been applied to low-polluting buses used in major Japanese cities and national parks, and is soon to be introduced in Australia.
Hino is also actively researching and developing trucks and buses that use Compressed Natural Gas (CNG), hydrogen and other forms of alternative energy.
Other breakthroughs in engine and vehicle development include the J Series engines – Hino’s latest midsize engine series. J Series engines are the world's first same bore stroke four, five and six-cylinder units to have high output and low energy consumption.
In this series, the J-1A engine was the first in the world to use the common rail electronically controlled fuel injection system. In addition to significantly reducing NOx emissions, the J-1A also reduces noise and vibration levels.
Hino uses automatic driving robots, vehicle vibration mode analysis equipment and vehicle vibration durability test equipment to evaluate everything from vehicle start-up acceleration and fuel consumption to cooling performance and driveability.
To accurately measure performance, test drives are conducted on Hino proving grounds and public roads, and collision tests are performed to maintain the highest standards of safety.
