Abstract
Three research projects are reported under the grant. The first is an investigation of a stratified-charge engine concept in which spark ignited combustion in an engine with a homogeneous rich charge is completed and then air is injected during the expansion stroke giving a leaner overall fuel-air ratio. The study showed substantial reduction of nitric oxides without increasing other emissions. Combustion efficiency was not increased and, because substantial work was needed to supply the compressed air, the engine efficiency was decreased. The second project is an investigation of nitrogen oxides produced by burning of liquid normal heptane from a fuel wetted porous cylinder in a cross flow of air. Variation of free stream air velocity and cylinder diameter showed the moles of nitric oxide per mole of fuel burned to be a weak function of Reynolds number. Soot produced by the flame and collected downstream has been identified as giving off significant amounts of nitric oxide indicating a carbon, nitric oxide interaction in the flame envelope. The third project consisted of a study of the part load operation of the Newhall divided chamber engine previously developed at U.W., Madison, an emissions and fuel economy evaluation of this engine relative to other engines and initiation of a study of the formation of hydrocarbons in a Texaco engine by utilization of an in-cylinder sampling technique. Reasons for abandonment of the divided chamber engine were its higher hydrocarbons and lower fuel economy relative to other engines and its sensitivity to knock.
