| Abstract;Honda has developed a turbo-charged common rail diesel engine for the European version of its CR-V Sports Utility Vehicle (SUV). During this development measures have been implemented to address the issue of the SUV body having high running resistance. The promotion of homogeneity in the air-fuel mixture through the employment of a shallow dish combustion chamber and the reduction of the diameter of the fuel injection nozzle holes has enhanced combustion and reduced engine-out Particulate Matter (PM). In addition, the use of a highly efficient EGR cooler has increased the volume of EGR. Combined with the achievement of optimal EGR gas temperature control by means of an EGR cooler bypass system, these factors together have enabled the achievement of a reduction in NOx emissions. The enhancement in exhaust emission performance resulting from these innovations has made the CR-V the first SUV which is compliant with the 2005 European diesel exhaust emissions standards (EURO-IV). A diesel particulate filter (DPF) is also employed in the CR-V. Optimization of the multi-fuel injection system, which is able to inject up to four times per cycle, control of the DPF temperature via the use of a variable geometry turbocharger (VGT), and intake control by means of the throttle valve have all resulted in reliable DPF regeneration performance. These various emission reduction technologies have resulted in the achievement of PM emissions less than one-tenth of those stipulated by EURO-IV. (author abst.) |
