The Design and Validation of Engine Intake Manifold Using Physical
International Journal of Automobile Engineering Research and Development (IJAuERD) ISSN (P): 2277–4785; ISSN (E): 2278–9413 Vol. 9, Issue 2, Dec 2019, 1–10 © TJPRC Pvt. Ltd. THE DESIGN AND VALIDATION OF ENGINE INTAKE MANIFOLD USING PHYSICAL EXPERIMENT AND CFD GURU DEEP SINGH, KESHAV KAUSHIK & PRADEEP KUMAR JAIN Department of Mechanical Engineering, Delhi Technological University, Main Bawana Road, New Delhi, India, ABSTRACT Race-car engineers aim to design an intake manifold which can maintain both low-end and top-end power without compromising the responsiveness of the engine throughout the power band. A major obstacle in achieving this goal is the rule requirement by FSAE for the mandatory presence of air intake restrictor which limits top-end power. In this paper, the selection criteria for design parameters such as runner length, plenum volume and intake geometry have been discussed. The effect of runner length and plenum volume on throttle response and manifold pressure has been studied through a physical exp. on a prototype variable geometry intake manifold. CFD simulations have been performed on ANSYS CFX to optimize the geometry for venturi and plenum. The geometry for which there was minimum pressure loss and maximum mass flow rate was chosen in the final design. The adopted approach was Original Article Article Original validated by conducting the same exp. on the designed intake manifold.

Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania’s next generation EGR system consisting of a poppet valve and a two stage cooler. -

Poppet Valve
POPPET VALVE A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve guide. In most applications a pressure differential helps to seal the valve and in some applications also open it. Other types Presta and Schrader valves used on tires are examples of poppet valves. The Presta valve has no spring and relies on a pressure differential for opening and closing while being inflated. Uses Poppet valves are used in most piston engines to open and close the intake and exhaust ports. Poppet valves are also used in many industrial process from controlling the flow of rocket fuel to controlling the flow of milk[[1]]. The poppet valve was also used in a limited fashion in steam engines, particularly steam locomotives. Most steam locomotives used slide valves or piston valves, but these designs, although mechanically simpler and very rugged, were significantly less efficient than the poppet valve. A number of designs of locomotive poppet valve system were tried, the most popular being the Italian Caprotti valve gear[[2]], the British Caprotti valve gear[[3]] (an improvement of the Italian one), the German Lentz rotary-cam valve gear, and two American versions by Franklin, their oscillating-cam valve gear and rotary-cam valve gear. They were used with some success, but they were less ruggedly reliable than traditional valve gear and did not see widespread adoption. In internal combustion engine poppet valve The valve is usually a flat disk of metal with a long rod known as the valve stem out one end. -

Matching of Internal Combustion Engine
CRANFIELD UNIVERSITY BAPTISTE BONNET MATCHING OF INTERNAL COMBUSTION ENGINE CHARACTERISTICS FOR CONTINUOUSLY VARIABLE TRANSMISSIONS SCHOOL OF ENGINEERING PHD THESIS CRANFIELD UNIVERSITY SCHOOL OF ENGINEERING, AUTOMOTIVE DEPARTMENT PHD THESIS BAPTISTE BONNET MATCHING OF INTERNAL COMBUSTION ENGINE CHARACTERISTICS FOR CONTINUOUSLY VARIABLE TRANSMISSIONS SUPERVISOR: PROF. NICHOLAS VAUGHAN 2007 This thesis is submitted in partial fulfilment of the requirements for the Degree of Doctor in Philosophy. © Cranfield University, 2007. All rights reserved. No part of this publication may be reproduced without the written permission of the copyright holder . PhD Thesis Abstract ABSTRACT This work proposes to match the engine characteristics to the requirements of the Continuously Variable Transmission [CVT] powertrain. The normal process is to pair the transmission to the engine and modify its calibration without considering the full potential to modify the engine. On the one hand continuously variable transmissions offer the possibility to operate the engine closer to its best efficiency. They benefit from the high versatility of the effective speed ratio between the wheel and the engine to match a driver requested power. On the other hand, this concept demands slightly different qualities from the gasoline or diesel engine. For instance, a torque margin is necessary in most cases to allow for engine speed controllability and transients often involve speed and torque together. The necessity for an appropriate engine matching approach to the CVT powertrain is justified in this thesis and supported by a survey of the current engineering trends with particular emphasis on CVT prospects. The trends towards a more integrated powertrain control system are highlighted, as well as the requirements on the engine behaviour itself.
