Engine Modeling of an Internal Combustion Engine
In the modern world, one of the largest concerns is the ever depleting supply of oil. The automotive industry is especially impacted. In recent years the price of gasoline has fluctuated substantially and the price of crude oil has reached record highs. The high price of gasoline coupled with the uncertainty of its availability and future price have put a high priority on fuel economy of an eng...
متن کاملFault Diagnosis Based on Parameter-Identification and Hybrid State Estimation Applied to an Internal Combustion Engine
The fault identification in a scenario of multiple concurrent faults is studied for an internal combustion engine exposed to sensor, actuator and structural faults. The focus is on numerical feasible algorithms with fixed timespace behavior that are suitable for real-time application. Two methodologies are tested in simulation. First we show that a single extended Kalman Filter (eKF) can be use...
متن کاملOptimal Control with Input Constraints Applied to Internal Combustion Engine Test Benches
Optimal control of nonlinear systems provides a major challenge in control engineering. Constraints on the input signals are common to many real-world applications and render the problem to be tackled even more complicated. This paper proposes a method to map the input constraints by nonlinear functions to the state equations of the system, afterwards an approximation of the solution of the res...
متن کاملControl Applied to a Reciprocating Internal Combustion Engine Test Bench under Transient Operation: Impact on Engine Performance and Pollutant Emissions
This work presents a methodology to adjust the electronic control system of a reciprocating internal combustion engine test bench and the effect of the control parameters on emissions produced by the engine under two extreme situations: unadjusted and adjusted, both under transient operation. The aim is to provide a tuning guide to those in charge of this equipment not needed to be experts in c...
متن کاملLES of spray and combustion in an internal combustion engine
With the ever rising need for better fuel efficiency and lower emissions, the development of better engine technology is essential. Different strategies are being considered to increase engine efficiency, such as direct injection or downsizing. Certain regimes are clearly identified as optimal for certain range of loads. For gasoline engines, the Homogeneous Charge Compression Ignition (HCCI) c...
