High swirl-inducing piston bowls in small diesel engines for emission reduction
TLDR
In this paper, the effect of reentrant piston bowl geometries on pollutant emissions from a single-cylinder diesel engine was investigated. But the simulation results indicated that the selected piston bowl geometry could actually be reducing the incylinder swirl and turbulence and the emission reduction may be entirely due to the introduction of the sac-less injector.About:

Aspects of Computer Simulation of Liquid-Fueled Combustors
A.D. Gosman,E. Ioannides +1 more
TL;DR: In this paper, an existing discrete droplet model of liquid sprays has been extended to include a stochastic representation of turbulent dispersion effects, and applications to simple test cases, including the dispersion of single particles, produce reasonable agreement.

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.

The autoignition of hydrocarbon fuels at high temperatures and pressures—Fitting of a mathematical model
TL;DR: In this paper, a systematic study has been carried out of the autoignition of a number of hydrocarbon fuels under engine-like conditions in a rapid compression machine, and the results confirm that there is a strong correlation between the performance of these fuels in engines and their auto-ignition properties measured in a Rapid Compression Machine (RCM).
