A computational study based on unsteady Reynolds-Averaged-Navier-Stokes that resolves
the gas-liquid interface was performed to examine the unsteady multiphase flow in a 4 …

The volumetric efficiency significantly influences engine output. Both design and dimensions
of an intake and exhaust system have large impact on volumetric efficiency. Experimental …

The paper aims to analyse the flow field at the entrance and within the filter housing of a
production four-cylinder, spark-ignition engine during the intake phase. To this purpose a …

The scavenging process in a direct-injection two-stroke research engine was examined by
using an electromagnetically controlled poppet valve to sample the trapped charge. A …

This paper presents a discussion of the difficulties in evaluating the discharge coefficients of
ports in the cylinder wall of high performance two-stroke engines. Traditionally such …

The flow processes in the crankcase of an internal combustion engine are essential for
many sub areas of a combustion engine. Piston cooling, oil transport through the main and …

Internal combustion engine (IC engine) vehicles are commonly used for transportation due
to their versatility. Due to this, efficiency in design process of IC engines is critical for the …

A 3-D CFD model for a small two-stroke SI engine has been developed using a commercial
code. The model simulates the scavenging process from the exhaust port opening to …
