Recently, the performance and exhaust emissions of high-speed direct injection (HSDI) diesel engines for passenger cars have been rapidly improved. In these engines, the power and torque densities have reached 50-60 kW/l and 160-170 Nm/l, respectively. In addition, the noise, vibration and harshness (NVH) and exhaust emissions have been decreasing toward a level that is comparable to that of ga...

Image and video indexing techniques are crucial in multimedia applications. A number of the indexing techniques that operate in the pixel domain have been reported in the literature. The advent of compression standards has led to the proliferation of indexing techniques in the compressed domain. In this paper, we present a critical review of the compressed domain indexing techniques proposed in...

To make engine and aftertreatment hardware choices for new emissions programs, it is often useful to prototype several candidate engine, aftertreatment and control systems, and run certification cycles. Building such a prototype requires a hardware selection control system that gracefully adapts to new hardware and rapidly achieves a level of performance similar to that of a production calibrat...

Diesel plasmatron reformer technology can provide substantial throughputs without the need of using a catalyst The use of the special plasma facilitates robust noncatalytic conversion of diesel fuel into hydrogen rich gas with hydrogen yields that could be sufficient for NOx trap regeneration applications. Higher yields can be obtained with the use of a catalyst. Plasmatron reformers could also...

Secondary organic aerosol (SOA) is formed from the atmospheric oxidation of gas-phase organic compounds leading to the formation of particle mass. Gasoline- and diesel-powered motor vehicles, both on/off-road, are important sources of SOA precursors. They emit complex mixtures of gas-phase organic compounds that vary in volatility and molecular structure-factors that influence their contributio...
