Clemson research developing integrated modeling and control systems to reduce particulates from GDI engines

Green Car Congress

Onori notes that an integrated approach to reduce gasoline particulates is necessary because engine operating conditions determine oxygen and fuel content and temperature of the exhaust gas, which influence the output of the catalytic converter, which in turn governs soot accumulation and oxidation in particulate filters.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ). In CCTF, the source of CO 2 determines the net carbon intensity of the fuel, Kreutz says.

Ford study shows Rankine waste heat recovery system on a light-duty vehicle could almost meet full vehicle accessory load on highway cycle

Green Car Congress

Inputs into the model include exhaust mass flow rate and temperature downstream of the catalytic converter, ORC component size and geometry. The evaporator was a shell-and-tube type design with exhaust gas passing through the tubes. Using the simplest ORC design (exhaust gas alone as the source of thermal input—i.e.,

Green Car Congress

at the ASME Turbo Expo 2016 conference this week in Seoul, South Korea. ​ Core exhaust loss. The “Core exhaust” loss is primarily due to thermal energy lost to the surroundings, although some excess kinetic energy and fluid friction associated pressure losses contribute as well. Core exhaust loss. Bypass flow loss.
