Emission regulations

Emission regulations is a general term for regulations that set upper limits for air polluting substances such as carbon monoxide, nitrogen oxides, hydrocarbons, and black smoke that are among the components of engine exhaust gas.
Today, as more focus is given to environmental protection challenges, these regulations are being tightened year by year, not only in Japan but on a global scale, and are expected to become even more stringent in the future.
These regulations are classified according to the model installed, and details vary by machine.
