This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Intake valve of a four stroke internal combustion (Ie) engine has been modelled to investigate the effects of intake valve diameter and intake valve angle on volumetric'efficiency and air flow properties of intake air in a four stroke internal combustion engine. It is found that the increase of intake valve diameter increases the peak vertical velocity component but decreases the peak horizontal velocity component of intake air in suction stroke. It is also found that the increase of intake valve diameter decreases the peak turbulence kinetic energy and dissipation rate of intake air to a small extent. The effects of intake valve diameters on the cylinder pressure in suction stroke become significant from the suction valve full opening timing to the middle of suction stroke but its effects become insignificant (diminished) at the time of suction valve closing. The effects of intake valve diameters on the intake air temperature are also found very small at the end suction stroke. Thus, the small variations between the computed pressure and temperature inside the cylinder at end of suction stroke for different intake valve diameters have little influence on volurr-Jletric efficiency. While investigating the effect of intake valve angle on the airflow properties, it is found that the larger intake valve angle decreases the vertical velocity component as well as the horizontal velocity component. The increase of intake valve angle decreases the turbulence kinetic energy and dissipation rate moderately. The effects of intake valve angles on the cylinder pressure and temperature in suction stroke are very small from intake valve opening timing until the end of suction stroke. Thus, the present investigation shows that variation in intake valve diameter has very small effect on volumetric efficiency and the necessity of increasing intake valve number is not so important. Moreover, intake valve angle can be increased in order to increase valve thickness and valve life.

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.

Download or read book Engine Modeling and Control written by Rolf Isermann and published by Springer. This book was released on 2014-07-01 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demands for internal combustion engines with regard to fuel consumption, emissions and driveability lead to more actuators, sensors and complex control functions. A systematic implementation of the electronic control systems requires mathematical models from basic design through simulation to calibration. The book treats physically-based as well as models based experimentally on test benches for gasoline (spark ignition) and diesel (compression ignition) engines and uses them for the design of the different control functions. The main topics are: - Development steps for engine control - Stationary and dynamic experimental modeling - Physical models of intake, combustion, mechanical system, turbocharger, exhaust, cooling, lubrication, drive train - Engine control structures, hardware, software, actuators, sensors, fuel supply, injection system, camshaft - Engine control methods, static and dynamic feedforward and feedback control, calibration and optimization, HiL, RCP, control software development - Control of gasoline engines, control of air/fuel, ignition, knock, idle, coolant, adaptive control functions - Control of diesel engines, combustion models, air flow and exhaust recirculation control, combustion-pressure-based control (HCCI), optimization of feedforward and feedback control, smoke limitation and emission control This book is an introduction to electronic engine management with many practical examples, measurements and research results. It is aimed at advanced students of electrical, mechanical, mechatronic and control engineering and at practicing engineers in the field of combustion engine and automotive engineering.

Download or read book Energy and the New Reality 1 written by L. D. Danny Harvey and published by Routledge. This book was released on 2010-08-12 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing and managing humanity's demand for energy is a fundamental part of the effort to mitigate climate change. In this, the most comprehensive textbook ever written on the subject, L.D. Danny Harvey lays out the theory and practice of how things must change if we are to meet our energy needs sustainably. The book begins with a succinct summary of the scientific basis for concern over global warming, then outlines energy basics and current patterns and trends in energy use. This is followed by a discussion of current and advanced technologies for the generation of electricity from fossil fuels. The book then considers in detail how energy is used, and how this use can be dramatically reduced, in the following end-use sectors: - buildings - transportation - industry - food and agriculture - municipal services The findings from these sector-by-sector assessments are then applied to generate scenarios of how global energy demand could evolve over the coming decades with full implementation of the identified and economically-feasible energy-saving potential. The book ends with a brief discussion of policies that can be used to reduce energy demand, but also addresses the limits of technologically-based improvements in efficiency in moderating demand and of the need to re-think some of our underlying assumptions concern ends with a brief discusing what we really need. Along with its companion volume on C-free energy supply, and accompanied by extensive supplementary online material, this is an essential resource for students and practitioners in engineering, architecture, environment and energy related fields. Online material includes: Excel-based computational exercises, teaching slides for each chapter, links to free software tools.
