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. -

HSDI Diesel Engines - Gas Exchange Optimization and the Impact on Reducing Emission
HSDI Diesel Engines - Gas Exchange Optimization and the Impact on Reducing Emission ABSTRACT All future powertrain developments must consider the primary tasks of achieving the required emission levels and CO2- values, while still providing comfort, good drivability, high reliability and affordable costs. One method for improving fuel economy in passenger vehicles that is beginning to be examined is the incorporation of downsizing. To achieve the levels of engine performance that will be required, increasing the boost pressure and/or rated speed is mandatory. When the boost pressure or the rated speed is increased, the result is an increase in the mass flow rate through the intake and exhaust ports and valves. Considering the impact of these changes, the port layout of the system has to be reanalyzed. The primary purpose of this study is to examine these effects on the port layout on a modern diesel combustion system and to present a promising concept. The study included flow measurements, PIV measurements of intake flow, CFD simulations of the flow field during intake and results from the thermodynamic test bench. One of the key aspects that needed to be examined was to demonstrate flow quality’s impact on combustion. A new port concept was developed as a result of this study that utilizes a variable valve lift to provide a highly variable swirl. This design enables a homogenous flow field in the cylinder, with excellent flow coefficient. The design also allows an increase in volumetric efficiency combined with a reduction in flow losses. INTRODUCTION The prerequisites for advanced concepts of High Speed Direct Injection (HSDI) Diesel Engines require that due to the rapidly increasing price of crude oil they must improve fuel economy and the heat-trapping ability of carbon dioxide emissions. -

Introduction to Internal Combustion Engines
k Chapter 1 Introduction to Internal Combustion Engines 1.1 INTRODUCTION The goals of this textbook are to describe how internal combustion engines work and provide insight into how engine performance can be modeled and analyzed. The main focus of the text is the application of the thermal sciences, including thermodynamics, combus- tion, fluid mechanics, and heat transfer, to internal combustion engines. An aspect upon which we will put considerable emphasis is the development of idealized models to repre- sent the actual features of an operating engine. Engineers use the methods and analyses introduced in the textbook to calculate the performance of proposed engine designs and to parameterize and correlate engines experiments. With the advent of high-speed computers and advanced measurement tech- niques, today’s internal combustion engine design process has evolved from being purely k k empirical to a rigorous semi-empirical process in which computer based engineering software is used to evaluate the performance of a proposed engine design even before the engine is built and tested. In addition to detailed analysis, the textbook contains numerous computer routines for calculating the various thermal and mechanical parameters that describe internal combustion engine operation. In this chapter we discuss the engineering parameters, such as thermal efficiency, mean effective pressure, and specific fuel consumption, that are used to characterize the over- all performance of internal combustion engines. Major engine cycles, configurations, and geometries are also covered. The following chapters will apply the thermal science princi- ples to determine an internal combustion engine’s temperature and pressure profiles, work, volumetric efficiency, and exhaust emissions.
