Fault detection and isolation (FDI) have become one of the most important aspects of automobile design. A new FDI scheme is developed for automotive engines in this paper. The method uses an independent radial basis function (RBF) neural network model to model engine dynamics, and the modelling errors are used to form the basis for residual generation. A dependent RBFNN model is a model which u...

Substantial improvements in engine fuel e ciency torque and reduction of emissions are available with cam less actuation capable of continuous control of engine valve lift duration and timing A phenomenological model has been developed for an unthrottled operation that is key to e ciency gain An adaptive nonlinear controller has been designed to coordinate intake valve lift and duration by usin...

Performa kendaraan bermotor dapat dilihat dari torsi dan daya. Baik tidaknya kualitas pembakaran akan mempengaruhi performa (torsi daya) sepeda motor, baiknya sejalan dengan performa. Proses di ruang bakar dipengaruhi oleh beberapa faktor seperti temperatur, densitas, turbulensi udara, serta komposisi udara bahan bakar. Peningkatan menjadi salah satu cara untuk meningkatkan mesin, dimana teknol...

This paper introduces a model-based controller designed to minimize the total unburned hydrocarbons produced by the internal combustion engine and processed by the three way catalytic converter, during the warm-up period. We assume to feed back the temperature of the exhaust gas; having in mind to decouple the control of combustion from the control of intake manifold, we assumed as controllable...

ABSTRACT Stringent NOx and particulate emission constraints require high levels of exhaust gas recirculation. In this paper we model and analyze a Variable Valve Timing methodology that in steady-state achieves large levels of internal Exhaust Gas Recirculation (iEGR) or residual charge in Compression Ignition Direct Injection (CIDI) engines. Current external Exhaust Gas Recirculation (eEGR) te...

In this paper a fuzzy controller is proposed to regulate the intake manifold pressure and the fresh mass airflow of diesel engines simultaneously. The instrumentation set usually embedded in a mass-produced passenger car has been considered. Unlike many multi-variable controllers, the proposed structure requires neither an internal model nor identification algorithms. In comparison to controlle...
