Book Investigation of 1 dimensional Analysis for Two stroke Spark Ignition SI Engine

Download or read book Investigation of 1 dimensional Analysis for Two stroke Spark Ignition SI Engine written by Zabidi Mohamad and published by . This book was released on 2008 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project is based on two-stroke engine. The two-stroke engine will be used as the testing engine that the performances can be determined. The objective of this project is to investigate and analysis the performance of two-stroke engine using a 1-Dimensional (engine gas dynamic) software. From this objective, the outcome of the project can be determined by using the 1-Dimensional software. The outcomes that need to be determined from this project are the performances of the engine. The 1-Dimensional software that was using in this project is GT-Power. GT-Power is using to model and simulate the two-stroke engine. First, the parameters of the two-stroke engine had been measured and then the modeling of the two-stroke engine had been built and simulated. After simulation process, the performances of the engines can be obtained right away. There are many information that can be taken from the GT-Power after simulating the engine but for analyzing, only several data had been chosen. Those data are pressure for scavenged port, in-cylinder and exhaust port, temperature for scavenged port, in-cylinder and exhaust port, brake power, brake torque, indicated mean effective pressure and brake specific fuel consumption. All of this information had been analyzed and the optimum engine speed had been determined at 1500 RPM to 2500 RPM because in this range, the brake torque and brake power is maximum while the brake specific fuel consumption also low.

Book Modeling and Control of EGR on Marine Two Stroke Diesel Engines

Download or read book Modeling and Control of EGR on Marine Two Stroke Diesel Engines written by Xavier Llamas and published by Linköping University Electronic Press. This book was released on 2018-02-20 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels. To reduce the marine freight impact on the environment, the International Maritime Organization (IMO) has introduced stricter limits on the engine pollutant emissions. One of these new restrictions, named Tier III, sets the maximum NOx emissions permitted. New emission reduction technologies have to be developed to fulfill the Tier III limits on two-stroke engines since adjusting the engine combustion alone is not sufficient. There are several promising technologies to achieve the required NOx reductions, Exhaust Gas Recirculation (EGR) is one of them. For automotive applications, EGR is a mature technology, and many of the research findings can be used directly in marine applications. However, there are some differences in marine two-stroke engines, which require further development to apply and control EGR. The number of available engines for testing EGR controllers on ships and test beds is low due to the recent introduction of EGR. Hence, engine simulation models are a good alternative for developing controllers, and many different engine loading scenarios can be simulated without the high costs of running real engine tests. The primary focus of this thesis is the development and validation of models for two-stroke marine engines with EGR. The modeling follows a Mean Value Engine Model (MVEM) approach, which has a low computational complexity and permits faster than real-time simulations suitable for controller testing. A parameterization process that deals with the low measurement data availability, compared to the available data on automotive engines, is also investigated and described. As a result, the proposed model is parameterized to two different two-stroke engines showing a good agreement with the measurements in both stationary and dynamic conditions. Several engine components have been developed. One of these is a new analytic in-cylinder pressure model that captures the influence of the injection and exhaust valve timings without increasing the simulation time. A new compressor model that can extrapolate to low speeds and pressure ratios in a physically sound way is also described. This compressor model is a requirement to be able to simulate low engine loads. Moreover, a novel parameterization algorithm is shown to handle well the model nonlinearities and to obtain a good model agreement with a large number of tested compressor maps. Furthermore, the engine model is complemented with dynamic models for ship and propeller to be able to simulate transient sailing scenarios, where good EGR controller performance is crucial. The model is used to identify the low load area as the most challenging for the controller performance, due to the slower engine air path dynamics. Further low load simulations indicate that sensor bias can be problematic and lead to an undesired black smoke formation, while errors in the parameters of the controller flow estimators are not as critical. This result is valuable because for a newly built engine a proper sensor setup is more straightforward to verify than to get the right parameters for the flow estimators.

Book Introduction to Modeling and Control of Internal Combustion Engine Systems

Download or read book Introduction to Modeling and Control of Internal Combustion Engine Systems written by Lino Guzzella and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internal combustion engines still have a potential for substantial improvements, particularly with regard to fuel efficiency and environmental compatibility. These goals can be achieved with help of control systems. Modeling and Control of Internal Combustion Engines (ICE) addresses these issues by offering an introduction to cost-effective model-based control system design for ICE. The primary emphasis is put on the ICE and its auxiliary devices. Mathematical models for these processes are developed in the text and selected feedforward and feedback control problems are discussed. The appendix contains a summary of the most important controller analysis and design methods, and a case study that analyzes a simplified idle-speed control problem. The book is written for students interested in the design of classical and novel ICE control systems.

Book Methods for Modeling the Dynamic Mass Flows in a Large Two stroke Diesel Engine with EGR

Download or read book Methods for Modeling the Dynamic Mass Flows in a Large Two stroke Diesel Engine with EGR written by Guillem Alegret Nadal and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this project different methods to model two-stroke diesel engines have been investigated. The goal of the project is to obtain a model capable to capture both the steady states and the transients of the engine system. The interest MAN Diesel&Turbo has in this model is to obtain a reliable simulation platform to be used as a tool to evaluate the performance of new control systems for the Exhaust Gas Recirculation (EGR) system. A non-linear model of the engine air-path with EGR is derived and validated against measurements. The specific engine corresponds to a 4T50ME-X located at MAN Diesel&Turbo research center. The model consists of the following components: the turbocharger, the scavenging and exhaust manifolds, the cylinders and the EGR system. The turbocharger model is externalized to an advance simulator software (GT-Power), all other components are modeled in Simulink. A Seiliger cycle capable of handling variable exhaust valve opening and closing is proposed. The polytropic coefficients for the compression and expansion are analytically estimated from in-cylinder pressure measurements. The model derived in this project is capable to fit well the measured data in steady states. The appropriate dynamics are obtained in transient operations, although the model shows a generalized faster response than the measured data.
