Diesel technologies will get progressively greener over the next few years, according to a new report.

In its report The European Market for Next-Generation Diesel Engine Technologies, growth consulting company Frost & Sullivan shows that diesel engine technologies have already registered tremendous growth in recent years.

Now, with the introduction of the Kyoto Protocol and the growing need for emissions to be controlled, an increase in the use of and research into green technologies for diesel engines is predicted.

Boosting techniques, engine management systems and exhaust gas after-treatment systems which enable diesel engines to provide reduced fuel consumption and emission are reportedly attracting the most interest from vehicle manufacturers.

The potential of valvetrain technology applications in reducing pollutants is also currently under investigation and is expected to play an "important role" in the future.

Fuel injection equipment is on the rise, with CRDI expected to become a standard feature in passenger cars due to its improved emission control and reduced fuel consumption.

Vehicle manufacturers are also said to be recognising the strong potential of diesel particulate filters with regard to particulate matter and oxides of nitrogen reduction.

The filters are projected to significantly grow up until 2012 with penetration rates likely to reach 35 per cent in 2010, in part due to government incentives to encourage take-up.
