Cycle-to-Cycle Fluctuations of Burned Fuel Mass in Spark Ignition Combustion Engines
M. Wendeker, G. Litak, M. Krupa
We examine a simple, fuel-air, model of combustion in spark ignition (si) engine with indirect injection. In our two fluid model, variations of fuel mass burned in cycle sequences…
Combustion Process in a Spark Ignition Engine: Dynamics and Noise Level Estimation
T. Kaminski, M. Wendeker, K. Urbanowicz +1
We analyse the experimental time series of internal pressure in a four cylinder spark ignition engine. In our experiment, performed for different spark advance angles, apart from u…
Specific Heat of Disordered Superconductors Induced by Negative Centers
Grzegorz Litak
We show that superconductors with inhomogeneous order parameters can show similar features as anisotropic ones. In this paper we study the low temperature specific heat dependence…
Nonlinear Vibration in Gear Systems
Grzegorz Litak, Michael I. Friswell
Gear box dynamics is characterised by a periodically changing stiffness and a backlash which can lead to a loss of the contact between the teeth. Due to backlash, the gear system h…
Nonperiodic Oscillations of Pressure in a Spark Ignition Engine
M. Wendeker, G. Litak, J. Czarnigowski +1
We report our results on non-periodic experimental time series of pressure in a spark ignition engine. The experiments were performed for a low rotational velocity of a crankshaft…
