Design and characteristics of electric supercharger for diesel engine acceleration by additional rapid air injection
      
Research results indicate that the electric supercharger can respond rapidly with the great flux, and it is independent of the operating conditions of a diesel engine.
      
De-noising of diesel vibration signal using wavelet packet and singular value decomposition
      
The vibration signals of diesel include excess noise that must be eliminated before extraction of characteristic parameters.
      
The SNR (signal-to-noise ratio) of the vibration signals of a diesel cylinder lid is the highest.
      
The diesel vibration waveforms of combustion and valve become clear and the extracted characteristic parameters become more precise.
      
Combustion and emissions of the diesel engine using bio-diesel fuel
      
The combustion and heat release of engines using diesel fuel and bio-diesel fuel have been investigated.
      
The economic performance and emission features of diesel engines using diesel fuel and bio-diesel fuel are compared.
      
The results also show that the specific fuel consumption of bio-diesel increases by about 12%.
      
Properties of La1-xCexCoO3 system perovskite-type catalysts for diesel engine exhaust removal
      
The catalytic activity of the catalysts in removal of NOx, total hydrocarbon (THC) and particulate matter (PM) from diesel exhaust gases were examined in detail using temperature-programmed reaction technique.
      
Deep desulfurization of diesel fuels by catalytic oxidation
      
Reaction feed was prepared by dissolving dibenzothiophene (DBT), which was selected as a model organosulfur compound in diesel fuels, in n-octane.
      
Combustion characteristics of a direct-injection diesel engine fueled with Fischer-Tropsch diesel
      
Fischer-Tropsch (F-T) diesel fuel is characterized by a high cetane number, a near-zero sulphur content and a very low aromatic level.
      
The results show that F-T diesel fuel exhibits a slightly longer injection delay and injection duration, an average of 18.7% shorter ignition delay, and a comparable total combustion duration when compared to those of conventional diesel fuel.
      
Meanwhile, F-T diesel fuel displays an average of 26.8% lower peak value of premixed burning rate and a higher peak value of diffusive burning rate.
      
In addition, the F-T diesel engine has a slightly lower peak combustion pressure, a far lower rate of pressure rise, and a lower mechanical load and combustion noise than the conventional diesel engine.
      
The brake specific fuel consumption is lower and the effective thermal efficiency is higher for F-T diesel fuel operation.
