Parameter Identifiability and Parameter Estimation of a Diesel Engine Combustion Model
In this paper an original method based on the link between a piecewise identifiability analysis and a piecewise numerical estimation is presented for estimating parameters of a phenomenological diesel engine combustion model. This model is used for design, validation and pre-tuning of engine control laws. A cascade algebro-differential elimination method is used for studying identifiability. Th...

متن کاملDecreasing NOx of a Low-Speed Two-Stroke Marine Diesel Engine by Using In-Cylinder Emission Control Measures
The authors applied one-dimensional (1-D) simulation and 3-D Computational Fluid Dynamics (CFD) simulation to evaluate the potential of in-cylinder control methods on a low-speed 2-stroke marine engine to reach the International Maritime Organization (IMO) Tier 3 NOx emissions standards. Reducing the combustion temperature is an important in-cylinder measure to decrease NOx emissions of marine ...
متن کاملStudy of Low-Temperature-Combustion Diesel Engines
Fuel cells have been recognized as a feasible alternative to current IC engines. A significant technical problem yet to be resolved is the on bound fuel supply before fuel cells can be practically used for vehicles. Use of an on-board fuel reformer can mitigate the fuel supply issue. In particular, using a diesel engine as on-board fuel reformer, combined with a fuel cell, is a strong candidate...
متن کاملA New Formulation of Multi-zone Combustion Engine Models
Cylinder pressure simulation has grown to become an important tool when developing and evaluating new engine concepts and control strategies. A new formulation of zero-dimensional multi-zone models is developed and described. A general model structure is formulated that rely on a set of differential algebraic equations that are easy to solve. The selected formulation also results in models that...
