Diss . ETH No . 19386 INDIVIDUAL CYLINDER AIR - FUEL RATIO CONTROL
The thesis presents a complete framework for the design of an individual cylinder air-fuel ratio (A/F) controller that aims to further reduce the exhaust emissions of modern automotive gasoline engines. It is well known that this type of controller relies on a correct estimation of the A/F of the individual cylinders. Otherwise, the control system can become unstable. Therefore, the conditions ...
متن کاملReal-time Nonlinear Individual Cylinder Air Fuel Ratio Observer on a Diesel Engine Test Bench
We propose an estimator of the individual cylinder air fuel ratios in a turbocharged Diesel Engine using as only sensor the single air fuel ratio sensor placed downstream the turbine. The observer consists of a nonlinear filter designed on a physics-based time-varying model for the engine dynamics. Convergence is proven, using a Lyapounov function. Performance is studied through simulations and...
متن کاملIndividual cylinder characteristic estimation for a spark injection engine
Engine control policies are mostly based on the assumption that all injectors have the same behavior independent of location and aging. In reality, injectors do vary and age. To contain variations around a nominal value, tight tolerances are imposed on the manufacturing process. Even if the manufacturing process is tightly controlled, the air-to-fuel ratio needed to satisfy emission constraints...
متن کاملSix Degrees Crankshaft Individual Air Fuel Ratio Estimation of Diesel Engines for Cylinder Balancing Purpose
In the context of modern engine control, one important variable is the individual Air Fuel Ratio (AFR) which is a good representation of the produced torque. It results from various inputs such as injected quantities, boost pressure, and the exhaust gas recirculation (EGR) rate. Further, for forthcoming HCCI engines and regeneration filters (Particulate filters, DeNOx), even slight AFR unbalanc...
متن کاملIndividual Air-Fuel Ratio Balancing Control for Multi-Cylinder SI Engines: Modeling and Validation
The three phase catalyst is popularly employed in modern engines for exhaust control and its catalytic efficiency is determined by the Air-Fuel ratio (A/F). In this paper, individual A/F control problem is addressed for a multi-cylinder SI engine, of which one exhaust pipe is shared by many cylinders. Firstly, an overlap model to describe the dynamics from individual fuel injection to A/F value...
