THE IMPORTANCE OF PRE-TRIAL CHAMBER IN CRIMINAL PROCEEDINGS. PROCEDURE AND CONTROVERSIAL ISSUES [PDF]

Challenges of the Knowledge Society, 2022
Following a legislative proposal to eliminate the pre-trial chamber phase from the criminal proceedings, I decided to study its properties and express my opinion on its importance. Analyzing the pre-trial chamber and the trial procedure, I found that its

Extensive validation of a combustion and pollutant emission model of a pre-chamber engine including different pre-chamber geometries

Fuel
In this work, a 0D/1D model of a single-cylinder pre-chamber spark ignition (PCSI) engine is extensively validated with experimental data in terms of performance, combustion, and emissions by varying the pre-chamber geometry and operating conditions. In the first stage, an experimental study is carried out on the PCSI engine at 1600 rpm and wide-open ...

Combustion analysis in a natural gas engine with pre-chamber by three-dimensional numerical simulation

Nihon Kikai Gakkai ronbunshu, 2015
Highly efficient natural gas engines have been widely used in wide range of sectors from industry and transportation. However, because combustion process in gas engines with a pre-chamber is very complicated, it is difficult to experimentally investigate
