TLDR
A radioactive tracer technique was developed to determine the contribution of oil from an engine sump to exhaust particulates collected on a filter as mentioned in this paper, which was applied to particulate emissions produced by an automotive diesel engine which was operated on an engine dynamometer over a range of steady state conditions.Abstract:
A radioactive tracer technique was developed to determine the contribution of oil from an engine sump to exhaust particulates collected on a filter. The technique was applied to particulate emissions produced by an automotive diesel engine which was operated on an engine dynamometer over a range of steady-state conditions. Results indicated that from 1.5 to 25 mass percent of particulate matter, depending on speed and load, consisted of material from engine oil. The oil contribution to particulate matter's extractable organic portion varied from 16-80%. The greatest contribution from oil was generally observed at high test speeds.read more

Diesel particulate emission control
TL;DR: In this article, the authors reviewed the emission control of particulates from diesel exhaust gases and the effects of various emission components on human health and the environment, and subsequently the emission standards for particulates and for NOx, which have been introduced worldwide, will be summarized.

TL;DR: In this paper, the authors used a chassis dynamometer to measure the particle-associated organics (PAHs) emitted from the tail pipe of a diesel engine and used this knowledge as a basis for a toxicological evaluation of diesel engine emissions.

Diesel Particulates—What They Are and Why
Charles A. Amann,Donald C Siegla +1 more
TL;DR: The diesel passenger car offers a substantial advantage in fuel economy over its gasoline-powered counterpart, but the long-range future of the diesel in this application is threatened by future federal standards on exhaust particular emissions as discussed by the authors.

Fuel Composition Effects on Heavy-Duty Diesel Particulate Emissions
J. C. Wall,S. K. Hoekman +1 more
TL;DR: In this article, the effects of fuel composition on diesel exhaust particulate emissions have been studied at several steady-state operating conditions using a heavy-duty laboratory engine, and the results showed that fuel sulfur was the dominant fuel factor in particulate formation.

Simultaneous control of particulate and NOx emissions from diesel engines
TL;DR: In this paper, the authors describe the principles of operation of Rhoˆne-Poulenc's cerium fuel-borne catalyst and the factors that govern its use, and present a system which is currently being proposed for the simultaneous control of diesel particulate matter and NO x emissions.

Combustion of droplets of heavy liquid fuels
TL;DR: In this paper, it was shown that the rate of combustion of fuel spray is a complicated function of the size and velocity distribution of the droplets, the physical and chemical properties of the fuel, its environment, and the character of the mixing process of the spray with air and with combustion products, which can be summarized as follows: as the oil droplets enter the furnace, they receive heat by convection from preheated combustion air and from recycled combustion products.

Methodology for Determining Particulate and Gaseous Diesel Hydrocarbon Emissions
Frank Black,Larry E. High +1 more
TL;DR: In this article, an analytical procedure for the measurement of diesel organic emissions, including the particulate and gas phases, from carbon number 1 to carbon number 40, was described, and the partitioning of the emitted organics between the gas and particulate phases was examined with a variety of controllable sampling parameters.
