High compression spark ignition engine with Variable Compression Ratio using Active Combustion Chamber.

The Archives of Automotive Engineering – Archiwum Motoryzacji, 2019
Abstract In this article Authors present the continuation of the calculations for theoretical ACC engine cycle, considering additionally “VCR function” – changeable compression level. For this purpose the self-acting volume change, realized by ACC system, was used. The ACC system was adjusted appropriately to control the compression level. The analysis

Suppression of X-rays from radiative shocks by their thin-shell instability

, 2014
We examine X-rays from radiatively cooled shocks, focusing on how their thin-shell instability reduces X-ray emission. For 2D simulations of collision between equal expanding winds, we carry out a parameter study of such instability as a function of the ...

Effect of Exhaust Gas Recirculation on Combustion Characteristics of Ultra-Low-Sulfur Diesel in Conventional and PPCI Regimes for a High-Compression-Ratio Engine

Energies
Low temperature combustion (LTC) mitigates the nitrogen oxide (NOx) and particulate matter (PM) trade-off in conventional compression ignition engines. Significant research on LTC using partially premixed charge compression ignition (PPCI) has typically ...
