Characterization of spray and combustion of diesel-alcohol blends in a constant volume chamber
… blends was investigated. An optical-accessible constant volume chamber capable of controlling ambient temperature, pressure and oxygen concentration was used to mimic the environmental conditions inside a real diesel engine cylinder. ABE fuel with typical volumetric ratios of 30% acetone, 60% …

Combustion characteristics of aluminum oxide nanoparticle additives in diesel in a constant volume chamber
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-05-01

Spray and combustion characteristics of acetone-butanol-ethanol and diesel in a constant volume chamber and a diesel engine
… provided by a high-pressure, high-temperature constant volume chamber. In-cylinder pressure traces were calculated to derive apparent heat release rates, high-speed Mie-scattering images were acquired to characterize liquid spray penetration, and natural flame luminosity was also captured to …

A Five-Zone Model for Direct Injection Diesel Combustion
… of the model were compared with data from a constant volume combustion vessel and two single-cylinder direct injection diesel engines. The modeled heat release results included all basic features of diesel combustion. Expected trends were seen in the ignition delay and premixed burn model …

Visualization of transient single- and two-phase jets created by diesel engine injectors
… controlled injectors, were observed in a constant-volume chamber charged with air, the pressure of which varied from atmospheric to 3.5 MPa. The injection (gas-to-chamber) pressure ratio varied from 1.5 to 8 for gas injection. The liquid-gas mass ratio of the injected mixture for the …

Air/fuel mixing enhancement and emission reduction through intake port design and various fuel emulsions for diesel combustion
… c) High speed imaging was carried out in a constant volume chamber to reveal the spray and combustion processes of diesel fuel with various additives under various ambient conditions. Quantitative analysis of spray penetration, soot lift-off length, broadband natural flame luminosity and …

Investigation of combustion enhancement with biomass derived fuels blended with diesel
… ethanol) were studied under various engine and constant volume chamber conditions. The results obtained demonstrate the potential of ABE as an alternative fuel for diesel and explain the effects of the ABE components on the combustion process. While there are concerns in regards to the …

Multihole injectors for direct-injection gasoline engines
… injected into a high-pressure/temperature constant-volume chamber have been visualised and quantified in terms of droplet velocity and diameter with a two-component phase-Doppler Anemometry (PDA) system at injection pressures up to 200bar and chamber pressures varying from atmospheric to …
