To create a diagnostic system for diesel engines, it is necessary to analyze a huge amount of data obtained from the automated test systems for diesel engines. Therefore, it is worth to implement the analysis with the help of an artificial neural network. The application of the artificial neural network for diesel engine fault clustering allows reducing the amount of stored data by creation of a knowledge...
Back-Propagation algorithm is one of the most popular algorithms in neural network. But it converges slowly, easily falling into local minima. This paper presents an improved BP algorithm, which can adjust learning rate using golden section method. Based on the algorithm, a diesel engine fault diagnosis system is designed. The simulation results indicate that the algorithm has much faster learning...
As testing the marine large-scale low-speed two stroke engine to determine the engine performance map for different working conditions costs too much time and money. So the prediction of the marine engine exhaust emissions modelling is developed to define how the inputs affect the outputs. The marine engine exhaust emissions were measured for different engine loads conditions. Using Radial Basis Function...
Emission legislation has forced the pace of development of engine management functions. Legislation that will be applied to diesel engines during the period 2010-2020 continue to put great emphasis on both nitrogen oxides NOx and particulate matter (PM). With the increasing effort to reduce emissions and maintain fuel economy manufacturers are focussing on engine control. Engine control requires data...
Ignition timing is crucial to the performance, efficiency and emissions of a spark ignition engine. This paper presents a new approach to achieve the optimizing ignition control in gaseous fuel engine by using RBF neural network. In order to meet the control objective, the relationship of ignition angle and gaseous fuel engine performance is studied. The learning algorithm of RBF neural network is...
For improving power output, fuel economy, and emissions of diesel engines, pressure feedback technology is introduced to electronic control high pressure common rail system. In this paper, the geometry characteristic index in the pressure difference curve is presented after analyzing pressure difference curve; the relations of the pressure characteristic indexes with injection parameter, output torque...
