Reference Management for Aftertreatment Temperature Control of Automotive Diesel Engines

Application of Biodiesel in Automotive Diesel Engines

Diesel engines due to the better fuel economy have been widely used in automotive area. However, the limited reserve of fossil fuel and deteriorating environment have made scien‐ tists seek to alternative fuels for diesel while keeping the high efficiency of diesel engine. Fuel consumption is expected to increase from 86 million barrels per day to 112 million bar‐ rels per day by 2035 according...

Aftertreatment control and adaptation for automotive lean burn engines with HEGO sensors

Control of aftertreatment systems for lean burn technology engines represents a big challenge, due to the lack of on-board emission measurements and the sensitivity of the hardware components to ageing and sulphur poisoning. In this paper, we consider the control and adaptation of aftertreatment systems involving lean NOx trap (LNT). A phenomenological LNT model is presented to facilitate the m...

A New Approach for NOx Soft Sensors for the Aftertreatment of Diesel Engines

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...

Study of Low-Temperature-Combustion Diesel Engines

Fuel cells have been recognized as a feasible alternative to current IC engines. A significant technical problem yet to be resolved is the on bound fuel supply before fuel cells can be practically used for vehicles. Use of an on-board fuel reformer can mitigate the fuel supply issue. In particular, using a diesel engine as on-board fuel reformer, combined with a fuel cell, is a strong candidate...
