Formation mechanisms of combustion chamber deposits
Combustion chamber deposits are found in virtually all internal combustion engines after a few hundred hours of operation. Deposits form on cylinder, piston, and head surfaces that are in contact with fuel-air mixture during the engine cycle. The effects of deposits include increased engine-out NOx …

The analytical design of a turbo-jet combustion chamber.
A "can" type combustion chamber was designed using all available proved concepts. A survey of existing designs was made to arrive at a logical design point. The fact that parallel flow would exist within the chamber was noted, and the burner was designed to obtain the required flow within an equal …

Quantification of Velocity at the Sparkplug in a Lab Scale Combustion Chamber
… Under lean or diluted conditions, however, the combustion speed is reduced. Therefore, to speed up the combustion, in-cylinder turbulence is induced which may impede the spark initiation. This research aims to quantify the turbulence in a constant volume optical combustion chamber. An Improved …

Simulation of solid fuel combustion in the cyclone combustion chamber using fluent-14.0
… way to done this method is by using the Cyclone Combustion chamber. Cyclone combustor is known as the separator of the ash from the gaseous products of the solid fuel. The objectives of this study are to demonstrated the flow characteristic, identify velocity and temperature distributions inside …

Emissions, efficiency, and combustion chamber conditions of a smokeless, hand-fired coal heater
The emissions, efficiency, and combustion chamber conditions of the Rayburn Prince 76, a clean-burning, hand-fired coal heater developed by the British have been studied. It was desired to determine if the downdraft design of the Prince would lead to low emissions when operated on American coals. …

Thermal properties of combustion chamber deposits and their effect on engine heat transfer and octane requirement increase
An investigation of the thermal properties of combustion chamber deposits and their effect on engine heat transfer and Octane Requirement Increase (ORI) has been completed. Deposits were grown in a Chrysler 4-cylinder 2.2 liter engine with total test times of 50- and 250-hours. Two fuels were used, …

Investigation of Clean Diesel Combustion With Oxygenated Fuels in a Constant -Volume Combustion Chamber Using Forward Illumination Light Extinction Technique
… soot reduction performances at different diesel combustion modes. In the premixed combustion mode, the higher oxygen efficiency from TPME due to its molecular structure advantage contributes to the less soot generation. While at mixing controlled combustion mode, DBM oxygenated fuel has less soot …

The development and implementation of a hybrid rocket motor thrust stand to investigate the relationship between combustion chamber pressure and graphite rocket nozzle erosion in hybrid rocket motors
… to insulate the motor from the heat produced by combustion. Over time these inserts will erode due to oxidation at the surface wherein oxidizing species found in the combustion products react with the carbon to form carbon monoxide. It has been shown that the largest contributors/oxidants to …
