Direct injection (DI) of cotton seed biodiesel (CS100) with port fuel injection (PFI) of n-
butanol was used for producing Premixed Controlled Compression Ignition (PCCI) to …

This paper presents a model for on-line NOx estimation. The method uses both, low
frequency components and high frequency components of in-cylinder pressure signal: it …

This paper analyses the in-cylinder pressure oscillations in internal combustion engines,
which are initiated by combustion and resonate during the expansion stroke. A specific …

Exhaust temperature is a valuable parameter for engine control. However, measurement
conditions at the engine exhaust and the slow dynamic response of temperature sensors …

In the search for improved performance and control of combustion engines there is a search
for the sensors that gives information about the combustion profile and the state of the gases …

This paper presents a knock intensity metric calculation method based on the in-cylinder
pressure resonant frequency estimation to improve the quantification performance of knock …

This work presents a new method for the simultaneous estimation of the intake and residual
mass in an engine operating with negative valve overlap. The method exclusively uses the …

Accurate cylinder charge and composition estimation is crucial for proper combustion
control, however, current sensors and models show different issues for transient estimation …

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 …

The implantation of nitrogen oxide sensors in diesel engines was proposed in order to track
the emissions at the engine exhaust, with applications to the control and diagnosis of the …
