Wisdom & Woe from the Workshop
Worn camshaft wisdom & woe from the workshop This month we will be looking at camshafts and how to select the correct camshaft for your application. Most TVR applications utilise relatively high performance camshafts, so the longevity of these components is often compromised. This means that most TVR engines will require camshaft replacement at some point in their lifetime... Many TVR engines (e.g. Rover V8 and Cologne or Essex V6) have a single camshaft located in the centre of the engine block, with both intake and exhaust lobes on the same camshaft. This type of set-up translates the motion of the cam lobes to the intake and exhaust valves via followers, pushrods and rocker arms. Other TVR engines (e.g. Speed Six) have two separate camshafts located in the top of the cylinder head, with the intake lobes on one camshaft and the exhaust lobes on the other camshaft. This type of set-up translates the motion of the cam lobes to the intake and exhaust valves via solid finger followers. Rover V8 When selecting a non-standard camshaft for your application you first need to ensure that you have the ability to modify the fuel quantity and ignition timing, particularly at full load and preferably throughout the entire load/rpm range. If the camshaft is not significantly different from the original specification, then a slight adjustment of the fuel pressure and ignition advance at peak torque may be sufficient. If the camshaft is significantly different from the original then you may require some significant work in terms of fuel and ignition adjustments, to ensure that you get the most out of your chosen camshaft (e.g. -
Modeling and Analysis of Composite Automotive V8
MODELING AND ANALYSIS OF COMPOSITE AUTOMOTIVE V8 ENGINE B.Sreenivasulu1, K.Anil Kumar2, P.Paramesh3 1,2,3 Assistant Professor In Mechanical Engineering Dept, Sphoorthy Enginering College, Hyderabad, (India) ABSTRACT Heat losses are a major limiting factor for the efficiency of internal combustion engines. Furthermore, heat transfer phenomena cause thermally induced mechanical stresses compromising the reliability of engine components. The ability to predict heat transfer in engines plays an important role in engine development. Today, predictions are increasingly being done with numerical simulations at an ever earlier stage of engine development. These methods must be based on the understanding of the principles of heat transfer. In the present work V type multi cylinder engine assembly is modeled. This model is imported to ANSYS and done the steady state Thermal and Structural analysis for predicting thermal stress, temperature distribution, heat flux by comparing with two different material (FU 2451) from existing material (Aluminium).Heat transfer is one major important aspect of energy transformation in internal combustion (IC) engines. Locating hot spots in a solid wall can be used as an impetus to design a better cooling system. Fast transient heat flux between the combustion chamber and the solid wall must be investigated to understand the effects of the non-steady thermal environment. Keywords: Cylinder, Combustion Chamber, FU 2451. I INTRODUCTION A V8 engine is a V engine with eight barrels mounted on the crankcase in two banks of four chambers, much of the time set at a privilege plot to one another yet frequently at a narrower edge, with each of the eight cylinders driving a typical crankshaft. -

Cyclone 3.5 L Ecoboost, 3.5 Duratech and 3.7 L Ti-VCT V6 Engine
Cyclone 3.5L EcoBoost, 3.5 Duratech and 3.7L Ti-VCT V6 Engine Tech All 3 variants use the same forged crankshaft with 3.413” stroke. The difference is the bore, 3.64” for the 3.5/EcoBoost and 3.76” for the 3.7L version. The blocks are cast aluminum with floating cylinder walls and cast iron liners. They ap- pear to use the same block but we have not confirmed this yet. We’re interested to learn if the blocks use the same bell- housing pattern or are interchangeable between FWD, AWD and RWD applications. That was not the case with the 3.8 which used different FWD and RWD versions with the main difference being the bellhousing bolt patterns. Seems that just about all of the parts now use a QR symbol. All use the same powder metal connecting rod which includes a bushing on the pin end for a floating pin. The rod is shot peened for improved fatigue strength, has a decent cross-section and uses cap screws instead of through bolts. The rod shown on the left is a 96-04 3.8/4.2 powder metal rod, the Cyclone rod in the center and one of our favorite 351W forged I-beam rods on the right. Notice how the cross section of the Cyclone rod appears to be more like the 351W I-beam than the 3.8/4.2 rod which was much to weak for high perfor- mance applications. Only time, boost and nitrous will determine the durability and strength of the Cyclone rod, but since the EcoBoost engine has already been proven to provide exceptional durability in the 365-400 HP range with Ford’s factory tuning expertise, we can expect adequate durability at power levels around 500 HP or so with upper rev limits at 6500-7000 or so as long as the tuning is on the money without detonation. -

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. -
