The junk head can optionally be moveable between a higher compression ratio position (51) Int. Cl. closer to a top dead center of the piston and a lower F02B 75/04 (2006.01) compression ratio position further from the top dead center F02D I5/04 (2006.01) position of the piston. At least one intake port can deliver a (Continued) fluid comprising inlet air to a combustion chamber within (52) U.S. Cl. the cylinder. Combustion gases can be directed out of the CPC .............. F02B 75/042 (2013.01); F0IL 5/06 combustion volume through at least one exhaust port. One (2013.01); F0IL 7/04 (2013.01); F02B 75/041 or both of the intake port and the exhaust port can be opened (2013.01); F02D 15/04 (2013.01) and closed by operation of a sleeve valve that at least (58) Field of Classification Search partially encircles the piston.

Copyright © 2013 SAE International and Copyright@ 2013 SIAT, India ABSTRACT Opposed-piston (OP) engines were once widely used in Over the last eight years, Achates Power has perfected the OP ground and aviation applications and continue to be used engine architecture, demonstrating substantial breakthroughs today on ships. Offering both fuel efficiency and cost benefits in combustion and thermal efficiency after more than 3,300 over conventional, four-stroke engines, the OP architecture hours of dynamometer testing. While these breakthroughs also features size and weight advantages. Despite these will initially benefit the commercial and passenger vehicle advantages, however, historical OP engines have struggled markets—the focus of the company’s current development with emissions and oil consumption. Using modern efforts—the Achates Power OP engine is also a good fit for technology, science and engineering, Achates Power has other applications due to its high thermal efficiency, high overcome these challenges. The result: an opposed-piston, specific power and low heat rejection. two-stroke diesel engine design that provides a step-function improvement in brake thermal efficiency compared to conventional engines while meeting the most stringent, DESIGN ATTRIBUTES mandated emissions

  • 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.

  • Review of Advancement in Variable Valve Actuation of Internal Combustion Engines
    applied sciences Review Review of Advancement in Variable Valve Actuation of Internal Combustion Engines Zheng Lou 1,* and Guoming Zhu 2 1 LGD Technology, LLC, 11200 Fellows Creek Drive, Plymouth, MI 48170, USA 2 Mechanical Engineering, Michigan State University, East Lansing, MI 48824, USA; [email protected] * Correspondence: [email protected] Received: 16 December 2019; Accepted: 22 January 2020; Published: 11 February 2020 Abstract: The increasing concerns of air pollution and energy usage led to the electrification of the vehicle powertrain system in recent years. On the other hand, internal combustion engines were the dominant vehicle power source for more than a century, and they will continue to be used in most vehicles for decades to come; thus, it is necessary to employ advanced technologies to replace traditional mechanical systems with mechatronic systems to meet the ever-increasing demand of continuously improving engine efficiency with reduced emissions, where engine intake and the exhaust valve system represent key subsystems that affect the engine combustion efficiency and emissions. This paper reviews variable engine valve systems, including hydraulic and electrical variable valve timing systems, hydraulic multistep lift systems, continuously variable lift and timing valve systems, lost-motion systems, and electro-magnetic, electro-hydraulic, and electro-pneumatic variable valve actuation systems. Keywords: engine valve systems; continuously variable valve systems; engine valve system control; combustion optimization 1. Introduction With growing concerns on energy security and global warming, there are global efforts to develop more efficient vehicles with lower regulated emissions, including hybrid electrical vehicles, electrical vehicles, and fuel cell vehicles. Hybrid electrical vehicles became a significant part of vehicle production because of their overall efficiency, and they still pose a significant cost penalty, resulting in a stagnant market penetration of 3.2% and 2.7% in 2013 and 2018, respectively, in the United States (US), for example [1].

  • Design and Assembly of a Throttle for an HCCI Engine
    Design and assembly of a throttle for an HCCI engine ÀLEX POYO MUÑOZ Master of Science Thesis Stockholm, Sweden 2009 Design and assembly of a throttle for an HCCI engine Àlex Poyo Muñoz Master of Science Thesis MMK 2009:63 MFM129 KTH Industrial Engineering and Management Machine Design SE-100 44 STOCKHOLM Examensarbete MMK 2009:63 MFM129 Konstruktion och montering av ett gasspjäll för en HCCI-motor. Àlex Poyo Muñoz Godkänt Examinator Handledare 2009-Sept-18 Hans-Erik Ångström Hans-Erik Ångström Uppdragsgivare Kontaktperson KTH Hans-Erik Ångström Sammanfattning Denna rapport handlar om införandet av ett gasspjäll i den HCCI motor som utvecklas på Kungliga Tekniska Högskolan (KTH) i Stockholm. Detta gasspjäll styr effekten och arbetssättet i motorn. Med en gasspjäll är det möjligt att byta från gnistantändning till HCCI-läge. Under projektet har många andra områden förbättrats, till exempel luft- och oljepump. För att dra slutsatser är det nödvändigt att analysera några av motorns data som insamlats under utvecklingen, såsom cylindertryck, insprutningsdata och tändläge. Man analyserade data under olika tidpunkter av motorns utveckling, med olika komponenter, för att uppnå olika prestanda i varje enskilt fall. För att köra motorn i HCCI-läge är det nödvändigt att ha ett lambda-värde mellan 1,5 och 2. Även om resultaten visar att det är bättre att köra i "Pump + Throttle + Intake" kommer pumpen överbelastas på grund av ett extra tryckfall. Av detta skäl kommer är det nödvändigt att arbeta i "Throttle + Pump + Intake" i framtiden. Eftersom det är nödvändigt att minska insprutningstiden, av detta skäl, är det också viktigt att öka luftflödet.
