Control of peak pressures of an HCCI engine under varying swirl and operating parameters

T. KARTHIKEYA SHARMA,G. AMBA PRASAD RAO,K. MADHU MURTHY

Frontiers in Energy 2016, Volume 10, Issue 3,   Pages 337-346 doi: 10.1007/s11708-016-0401-2

Abstract: A single cylinder 1.6 L reentrant piston bowl diesel engine is chosen.bowl geometry, exhaust gas recirculation (EGR) and equivalence ratio under different swirl ratios inThe combined effect of four operating parameters, i.e., the speed of the engine, piston bowl geometry, EGR, and equivalence ratio with swirl ratios suggest that lower intake temperatures, reentrant pistonbowl, higher engine speeds and higher swirl ratios are favorable in controlling the peak pressures.

Performance of rolling piston type rotary compressor using fullerenes (C70) and NiFe

Ruixiang WANG,Yihao ZHANG,Yi LIAO

Frontiers in Energy 2020, Volume 14, Issue 3,   Pages 644-648 doi: 10.1007/s11708-017-0453-y

Abstract: A novel way for a compressor to improve its coefficient of performance was proposed in this paper. Fullerenes (C70) and NiFe O nanocomposites were modified by span 80 and dispersed in refrigeration oil by solid grinding (SG). Besides, the tribological properties of the nanocomposites were investigated using a four ball friction tester. The results show that when the mass concentration of fullerenes nanocomposite is higher than 60 ppm and the concentration of nano-oil is 2 g/L, the friction coefficient decreases from 0.13 to 0.06 which means the wear is reduced. The coefficient of performance of the compressor under the air conditioning test condition can be raised by 1.23%.
