“…Data are also available for chassis dynamometer tests of CNG-HDD vehicles (Crane and King, 1992;Dunlap et al, 1993;Unnasch et al, 1993;Wang et al, 1993aWang et al, , 1993bFritz andEgbuonu, 1993, Urban Consortium Task Force, 1994). Additional studies of engine dynamometer tests of CNG fuel engines are described in publications by Wallace, 1993a, 1993b;Karim et al, 1993;Swain et al, 1993;Varde et al, 1992. Currently, several ongoing projects could provide more information on in-use emissions of current technology production vehicles. The CleanFleet program has just released low mileage emissions results from nine CNG fuel delivery vans from Ford, Dodge, and Chevrolet with mileages ranging from 4,300 to 11,600.…”

“…The choice to switch to CNG has become strategic [5]. In recent years there has been increasing interest in the use of gaseous fuels in spark ignition engines for light and heavy vehicles [1][2][3][4][5] because the regulations on gas emissions are becoming increasingly stringent on pollutants (CO 2 , NOx, HC and CO) [6][7][8][9].…”

This paper proposes an experimental study on the performance and emissions in the lean operation (Ф=0.6-0.7) of a six-cylinder spark ignition engine fuelled with natural gas, pure methane and a mixture of hydrogen in methane (85 CH 4 , 15%H 2 by volume). Each fuel has been investigated at 1500 rpm and for various load conditions. Emissions, exhaust gas temperature and pressure cylinder were measured. The objective of the study is to determine how the load and equivalence ratio affect engine characteristics operating with natural gas and the hydrogen-methane mixture. The results show that the hydrogen addition increased HC and NO emissions, as well as the performance and cylinder pressure, but reduced the NOx, exhaust gas temperature and the CO and CO 2 emissions.

“…But the TWC is not an effective tool for reducing NO X emissions from lean burn engines, such as the spark ignited natural gas engine being discussed in this thesis. This is due to excess oxygen and lowered HC and CO emissions in the exhaust of lean burn engines [9]. Because of this problem, other means of reducing NO X emissions need to be developed.…”

Nitric oxide conversion in a spark-ignited natural gas engine

Reducing NO X emissions from natural gas engines has become increasingly important from an environmental standpoint. A large percentage of stationary engine applications are natural gas fueled. The cleanest of these large bore engines currently produce on the order of one gram of NO X per brake-horsepower hour (g/bhp-hr) of work done. The goal of this work is to reduce these emissions to 0.1 g/bhp-hr levels. Selective NO X Recirculation (SNR), a technology which will help achieve these 0.1 g/bhp-hr levels, is currently being studied at West Virginia University. SNR has been proven in gasoline and diesel engines, with up to 90% NO X conversion rates being achieved, but not much is I would also like to extend my gratitude to Dr. Gregory Thompson for his knowledge of the laboratory equipment, and Tom Spencer for his knowledge and humor. I thank Chamila, Emre, and Ram for their friendship and skills at the fooseball table, and also for their help with this research. I would also like to thank my brother and best man Craig for his interesting conversation, and my parents for their advice.
