Swirl chamber structure parameters are investigated on SD195( D×S =95 mm×115 mm)and SD2100( D×S =100 mm×115 mm) diesel engines. A new method which is named 4 stages accumulative heat release rate is developed.
Furthermore,at higher engine speeds, the ignition time delays by 11°-13° when the LPG mass fraction is higher than 20% and the peak heat release rate is far lower than that of diesel, and the combustion duration is extended by about 22°-25°.
An exothermic peak in DSC tracing was presented for glassy alloys Fe_(24)Zr_(76) and Ni_(24)Zr_(76), but two or three peaks for Co_(21)Zr_(79), Pd_(24.5)Zr_(75.5), Cu_(45)Zr_(55) and Cu_(67.5)Ti_(32.5).
when the mass ratio of AC/NaHCO3/L/Na-L/stabilizing agents is 4/0.8/0.6/1.0/6.2, the heat decomposition of compound blowing agent is slow and the heat liberation is moderate when the foaming material is heated. Thus the properties of the foaming material are superior and the cells are uniform and fine.
Connected bond energy change in coal and oxygen combination process, bond energy estimation method is gained to calculate upper and lower limit of oxidation heat liberation intensity of loose coal at different low temperature stage.
According to heat transfer theory and the change of temperature field determined through experiment of coal self ignite at low temperature stage, thermal equilibrium method is developed to calculate oxidation heat liberation intensity of loose coal at different low temperature stage.
Energy could not be translated into ATP effectively in the course of oxidative phosphorylation resulting in heat release.
The combustion and heat release of engines using diesel fuel and bio-diesel fuel have been investigated.
The initial heat release peak declines a little, the corresponding crankshaft angle changes in advance, and the combustion duration is prolonged.
It is shown that the allowance for the effects of the heat release of phase transition resulted in a rather notable change in the kinetics of nucleation even at a sufficiently high concentration of the passive gas.
The solution of the problem for the case in which the thickness of the heat release zone is neglected (the infinitely thin detonation wave model) was obtained in [1-3].
Furthermore, at low concentrations (up to 5 mM), Me2SnCl2 binds to the phosphate groups of DNA in an exothermic step and had no significant effect on double-strand DNA stability, confirmed by the fact that the Tm value did not change.
The compound organification and exothermic process of the solid phase copolymerization promoted the melting intercalation.
The thermody namic analysis indicated that the swelling process is an exothermic process.
Exothermic effects arising during silicon powder heating after their mechanical treatment were measured by synchronous TG-DSC thermal analysis method.

The heat liberation in the middle part of the transformation range and an essential influence of this effect on the structure of reverted austenite in the N25KhT2 alloy has been confirmed experimentally.
The method of reconstructing the true curve of heat liberation from the shape of the thermograms has been presented.
