Research and Development Trends in Combustion and Aftertreatment Systems for Next-Generation HSDI Diesel Engines

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...

Dynamic Optimization of Lean Burn Engine Aftertreatment

The competition to deliver fuel e cient and environmentally friendly vehicles is driving the 1 2 Submitted to Journal of Dynamics Systems, Measurement, & Control automotive industry to consider ever more complex powertrain systems. Adequate performance of these new highly interactive systems can no longer be obtained through traditional approaches, which are intensive in hardware use and nal co...

Analysis of Heavy Duty turbocharged Diesel engine response under cold transient operation with a pre-turbo aftertreatment exhaust manifold configuration

Diesel particulate filters are the most useful technology to reduce particulate matter from the exhaust gas of internal combustion engines. Although these devices have suffered an intense development in terms of the management of filtration and regeneration, the effect of the system location on the engine performance is still a key issue that needs to be properly addressed. The present work is ...

PSFC/JA-02-30 Onboard Plasmatron Generation of Hydrogen Rich Gas for Diesel Engine Exhaust Aftertreatment and Other Applications

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...
