Diagnostics of Diesel Combustion
1996The demands in car development are largely contradictory. The most discussed items with regard to the environment are fuel consumption and the exhaust emissions of the combustion engine. Although the development of the engine during the last few decades has made good progress, further knowledge on combustion processes is required.

Combustion performance of vehicle diesel motor
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011In this paper, we have mainly analyzed the four periods of diesel motor's combustion process, which includes the questions about ignition delay, rapid combustion period, slow combustion period and aux-combustion period. We also have studied the formation reasons about incomplete combustion, noise of ignition phenomenon, and exhaust smoke.

Looking in on Diesel Combustion
SAE Technical Paper Series, 1969<div class="htmlview paragraph">High-speed cine photography has been used to study the combustion process in a variety of diesel chambers. These chambers, used in engines of 12–1200 cu in. swept volume per cylinder, differ considerably in the level of air utilization achieved within the cylinder at acceptable exhaust color or temperature.</div&

Some More Light on Diesel Combustion
Proceedings of the Institution of Mechanical Engineers: Automobile Division, 1962This paper discusses the process of combustion, as revealed by high speed cinematography, in a small high speed diesel. Two direct injection types and one prechamber type were examined, and combustion sequences are shown. The phenomena are complex, but the main features are: (1) In small engines much of the fuel strikes the chamber wall and moves ...

Advances in Diesel Engine Combustion: Split Combustion
SAE Technical Paper Series, 2007<div class="htmlview paragraph">This paper describes a new Combustion System called “Split Combustion” (SC). It was derived from various strategies for a Homogeneous Diesel Combustion (HDC) to reduce nitric oxides (NO<sub>X</sub>) and particulate matter (PM) within a greater load range.</div> <div class="htmlview paragraph ...

Spray Combustion in Diesel Engines
SAE Technical Paper Series, 1988<div class="htmlview paragraph">A computer program, which applies the group combustion theory with a comprehensive treatment of thermal radiation to diesel engines, has been developed. A quasi-steady simulation including gas and liquid droplets flows, gas-to-droplets and droplets-to-droplets interactions, turbulence, finite chemical rate, and ...

The preferred drive engines for motor vehicles are based on combustion engines. They utilize the oxygen in the combustion air to convert the fuel-based chemical energy that predominantly consists of hydrocarbons into heat, which in turn is transferred to the engine’s working medium.

Cinematography of Combustion in Diesel Engines
The Journal of Photographic Science, 1957AbstractMethods used to film the injection and combustion processes in some forms of diesel combustion chamber are described. Rates of up to 15,000 frames/sec. were used with suitable lighting to show the distribution of injected fuel prior to self-ignition.
