Denso develops new fuel injection technology for automotive diesel engines

It is reported that Toyota Group Corporation Denso has announced the publication of a fuel injection technology for improved fuel efficiency and noise reduction of diesel engines. The name is “i-ART,” which allows the installation of pressure sensors on engine fuel injection devices. To control the amount of fuel injection and injection time.

Denso introduction, through the pressure sensor can detect the pressure of the fuel when the size of the discharge, through the computer to calculate the optimal injection amount and injection time, thereby improving the diesel engine injection accuracy and improve fuel efficiency. The test data shows that fuel efficiency is 2 to 5 percentage points higher than that of conventional diesel engines, and exhaust emissions are also greatly improved.

Diesel vehicles are more economical than petrol vehicles, and they are popularized in Europe and other regions. However, exhaust emission standards have become stricter. Automobile manufacturers have to adopt complex purification systems. If the "i-ART" technology is used, not only can the exhaust emission purification device be simplified. , but also reduce the cost of car manufacturing. Denki said that "i-ART" technology can also effectively solve the problem of the biodiesel that is currently prevalent but has a lot of impurities.
