Institution of Road Transport Engineers comments on criticism of diesel vehicles

 The Institute of Road Transport Engineers (IRTE) has responded to recent criticism of current use of diesel fuel in road vehicles.

“There are more meaningful and viable solutions to addressing the current situation, such as more reliable and accurate testing of individual manufacturer’s vehicles that mimic real-world conditions, and supporting the development of increasingly sophisticated filtration systems and fuel efficiency. Of equal importance is the need for stricter legislation that means individuals and operators cannot legally tamper with filters and other systems in place designed to minimise the environmental impact of diesel fuel,” stated Executive Director of IRTE, Ian Chisholm IEng FSOE FIRTE.

At the recent IRTE Conference, an annual event that brings together road transport experts including Andrew Banks, Chief Engineer (Engines Product Group) for Ricardo, who commented: “We are seeing legislation for greenhouse gas in the US now, which is driving a 9% improvement in fuel consumption by 2017 from a 2010 baseline. We expect the same thing to happen in Europe.”

Andrew also explained how Ricardo is currently working on reducing fuel consumption by decreasing engine friction, just one example of the multi-directional approach that IRTE observes as the most effective way to address current issues with diesel emissions that have been in the media recently.

“Modern diesel vehicles are significantly cleaner than those in the past,” added Ian Chisholm. “Unnecessarily scrapping diesel-powered vehicles already on the road in favour of new electric or hybrid vehicles has its own environmental repercussions. The issue of diesel fuel emissions is more complex than current mainstream media coverage would suggest, and what has recently happened calls for a considered, long-term response, rather than a reactionary swing in the opposite direction.”
