TLDR
In this paper, the effect of flame temperature on particulate carbon emission from divided-chamber diesel engines was examined by adding various quantities of 02 and N2 to the intake air with the engines operating at several different loads and speeds.Abstract:
The effect of flame temperature on particulate carbon emission from divided-chamber diesel engines was examined by adding various quantities of 02 and N2 to the intake air with the engines operating at several different loads and speeds. At a given operating condition for a fixed combustion chamber geometry, intake gas addition was expected to influence chemical kinetics without affecting the air-fuel mixing. Particulate carbon and CO were found to increase with N2 addition and decrease with 02 addition, whereas NOx emissions exhibited opposite trends.read more

The effects of exhaust gas recirculation on diesel combustion and emissions
TL;DR: In this paper, the effects of exhaust gas recirculation (EGR) on diesel engine combustion and exhaust emissions were identified and investigated experimentally: the reduction in oxygen supply to the engine, participation in the combustion process of carbon dioxide and water vapour present in the EGR, increase in the specific heat capacity of the engine inlet charge, increased INLET charge temperature and reduction in the inLET charge mass flowrate arising from the use of hot EGR.

The Dilution, Chemical, and Thermal Effects of Exhaust Gas Recirculation on Diesel Engine Emissions - Part 1: Effect of Reducing Inlet Charge Oxygen
TL;DR: In this paper, the replacement of some of the inlet air with EGR modifies the diesel combustion process and thereby affects the exhaust emissions, and the effects of oxygen replacement on ignition delay were isolated and quantified.

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.

The effects of carbon dioxide in exhaust gas recirculation on diesel engine emissions
TL;DR: In this paper, the effects of carbon dioxide (CO₂), a principal constituent of EGR, on combustion and emissions were analyzed and quantified experimentally on a high-speed direct injection diesel engine.

Oxidation of carbon between 1000–2000°c
TL;DR: In this paper, it was shown that the pyro graphite reaction curve reaches a maximum at a temperature of about 1100°C, which is 600°C less than the temperature at which the maximum rate with pyrographite at a pressure of 0.2 atm was observed, and the theory of Blyholder, Binford and Eyring, slightly modified, was shown satisfactorily for this difference between low and high pressure results.
