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. -

The 4.7 Liter “Next Generation” and “Semi-Hemi” V8 Engine (Dodge - Jeep)
The 4.7 Liter “Next Generation” and “semi-Hemi” V8 Engine (Dodge - Jeep) Chrysler’s first truly new V-8 since the 1960s, the “Corsair” 4.7 had better power, gas mileage, and emissions than the 5.2 liter engine it replaced; a new truck V6, the 3.7 , was based on it, replacing the 3.9 liter V6 based on the 5.2. The engine was reportedly designed as a replacement for the venerable 4-liter AMC I-6, with the 3.7 to replace the AMC 2.5. EGR and knock sensors were added in 2005. In 2007 (model year 2008), Chrysler replaced the 4.7 liter V8 with a new version. Power went from 230 hp to 290 hp (and up to 320 lb-feet of torque) with that move; gas mileage went up, and noise and vibration went down. The new 4.7-liter V-8 features 5.7-Hemi features such as two spark plugs per cylinder, with a high 9.8:1 compression ratio, and better port flow; but it has a new slant/squish combustion system design. Refinements included significant revisions to the induction system, reduced reciprocating mass via a lightweight piston/rod assembly, and reduced accessory drive speed. A new normally open valve lash adjuster system smooths the engine at idle, while electronic throttle control is needed for new stability systems. The engine will be manufactured at the Mack Avenue Engine Complex in Detroit. Chrysler's New Cammer: Mopar’s first all-new production V8 in 41 years By RICK EHRENBERG.

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]. -
