  • Nanoparticles: how small must we measure?

    20 March 2017

    Improving urban air quality is the major impetus for a continuing push towards monitoring and regulating particle emissions. Now attention is extending to include particles significantly below the threshold of current regulation, approaching the molecular range – and Ricardo is spearheading some of the latest research in this area as well as helping industry comply with existing and future regulation.

    In the continuing endeavour to control harmful emissions from motor vehicles, the measurement of particle numbers (PN) is now firmly a part of the European regulatory framework. The introduction of PN standards followed the pioneering work carried out by Ricardo ...

  • A PERSONAL VIEW: Are car dealer networks really up to the task of maintaining increasingly complex diesel aftertreatment systems?

    14 July 2016

    A personal viewpoint by Anthony Smith, Director, MediaTechnical Ltd

    A year ago if I’d been asked this question, my response would have been an undoubted ‘yes’. Now though, personal experience leads me to worry that things are not as they should be within the dealer networks; that we have perhaps gone too far down the pathway of allowing warning lights and ECU codes to be the primary factor in fault tracing.
    For largely isolated components such as tyre pressure or fluid level warnings, blown bulbs and so on, this abstract/reductionist approach is fine. But with highly complex systems such as ...

  • Unplugging the EV

    30 June 2016

    Thanks to the latest generation of wireless electric vehicle charging technologies such as Qualcomm Halo™, the inconvenience and hassle of using power cables to connect to charging points could soon be a thing of the past for EV and PHEV drivers. Anthony Smith reports

    Plugging in for a recharge has to be the least glamorous aspect of driving an electric vehicle (EV) or plug-in hybrid (PHEV). Whereas most drivers of conventional diesel or gasoline fuelled vehicles might typically need to visit the service station to refill their tank once every week or two, plug-in vehicles should ideally be recharged rather more frequently, requiring them to be parked close to a ...

  • Advanced ADEPT 48V affordable hybrid on path to meet future ultra-low vehicle emissions

    29 June 2016
    • Ricardo-led ADEPT programme aims to demonstrate technology capable of providing near full-hybrid equivalent fuel economy at significantly lower cost
    • ADEPT consortium successfully applies advanced mild hybrid technologies with 48V ‘intelligent electrification’ to a Ford Focus project demonstrator
    • Results of almost three years of intensive development and road and laboratory testing of ADEPT technology will be revealed at LCV2016

    Following almost three years of intensive testing, development and validation of advanced mild hybrid technologies with 48V ‘intelligent electrification’ applied to a Ford Focus project demonstrator, the ADEPT (advanced diesel-electric powertrain) consortium partners have announced ...

  • Achieving RDE NOx compliance in urban driving is possible, at a price, says Ricardo

    02 June 2016

    A range of aftertreatment technology options are available to automakers seeking to achieve compliance with the impending EU Real Driving Emissions (RDE) regulations – according to the results of a Ricardo research project to be presented today at the SIA Powertrain international conference and exhibition being held in Rouen, France.

    Future RDE emissions legislation and fleet average CO2 targets represent a challenge for automakers wishing to provide cost-effective light duty diesel vehicles. But while the costs of implementation can be significant, a range of technologies is available which, applied in a combination and manner appropriate to needs of the vehicle, can deliver compliant performance in terms of both NOx and CO2.

    Ricardo ...
