Clean technologies for the future The main advantage of the generation of HDi, High Pressure, direct injection, diesel engines is a 20% reduction in carbon dioxide (CO2) emissions as compared with the classic, indirect injection engines. There is also a 40% reduction in carbon monoxide, 50% in hydrocarbons and 60% in particles. The HDi FAP is fitted with a particles filter (FAP), and is intended to eliminate emissions of polluting soot particles (black exhaust smoke).

Less greenhouse effect Greenhouse effect is a natural phenomenon that facilitates life on earth, with the gas in the atmosphere such as CO2 absorbing the infrared rays given off by the sun. The greenhouse effect can change if the atmosphere contains too large an amount of CO2 (link to Peugeot World) that cannot be absorbed by photosynthesis:  the planet’s climate then heats up.

HDi engines provide over 20% savings in consumption as compared with previous-generation diesel engines, which translates into a matching drop in CO2 emissions that in turn is a reduction in greenhouse effect gases.

What is more, an HDi engine can take up to 30% of Biodiesel, which reduces CO2 emissions even further. The combination of HDi engines and Biodiesel (for the time being limited to corporate fleets) represents major progress in reducing CO2 emissions from cars.

How many Peugeot HDi engines are there? Until now 5,300,000 HDi engines have been sold worldwide since 1998, with Peugeot positioned as a major player in the development of clean diesel.
In 2000 the world debut of the particles filter on the 607 HDi marked a technological innovation of the make’s diesel engine, by providing not just reduced consumption through the use of HDi technology, but also a reduction of 99.9% in soot particles emissions.
