A direct transform for determining the trapped mass on an internal combustion engine based on the in-cylinder pressure resonance phenomenon

Broatch Jacobi, Jaime Alberto; Guardiola García, Carlos; Plá Moreno, Benjamín; Bares Moreno, Pau (Elsevier, 2015-10)

It has lately been demonstrated that the resonance of the in-cylinder pressure may be used for inferring the trapped mass in an internal combustion engine. The resonance frequency changes over time as the expansion stroke ...
Determination of the resonance response in an engine cylinder with a bowl-in-piston geometry by the finite element method for inferring the trapped mass

Broatch Jacobi, Jaime Alberto; Guardiola, Carlos; Bares-Moreno, Pau; Denia Guzmán, Francisco David (SAGE Publications (UK and US), 2016)

[EN] Cylinder resonance phenomenon in reciprocating engines consists of high-frequency pressure oscillations excited by the combustion. The frequency of these oscillations is proportional to the speed of sound on pent-roof ...
Estimation of trapped mass by in-cylinder pressure resonance in HCCI engines

Luján, José M.; Guardiola, Carlos; Plá Moreno, Benjamín; Bares-Moreno, Pau (Elsevier, 2016-01)

High pressure gradients at homogeneous charge compression ignition (HCCI) engines heavily excite the pressure resonance. The pressure resonant frequency depends on speed of sound in the cylinder, and thus on the bulk gas ...
