What is polluting the atmosphere?

Automobiles are generally divided into two groups by the fuel they use: gasoline or diesel. Diesel-powered vehicles consume a light oil fuel, known as diesel oil. The emissions in each type of vehicle’s exhaust gases are different due to these different fuels and their methods of combustion. Exhaust emissions from diesel vehicles contain less CO2 and hydrocarbons (HC) than gasoline engines, however they contain more nitrogen oxides (NOx) that might generate acid rain, and particulate matter (PM) which could be related to lung cancer and asthma.
What is DENSO doing to protect the air? DENSO products help to clean emission gases from both gasoline and diesel-powered vehicles, and we provide products designed to reduce traffic jams.

Common Rail System
This system is the heart of the diesel engine, used to inject fuel.
DPF (diesel particulate filter)
This filter further cleans exhaust gas discharged from the common rail system
Starter Generator
This equipment starts the engine and generates electricity used to power the variety of other parts in an automobile.
Car Navigation System
This is a directional guidance and mapping system to guide you in the correct direction to your destination, and to provide traffic information.
ETC (electronic toll collection system)
This system eliminates the need to stop at tollbooths, which usually creates traffic backups, in order to save fuel and reduce exhaust gas.
