IC Engines by V Ganeshan

I will be thankful for any constructive criticism for improvements in future editions. Variety of new problems have been added in various chapters and number of exercise problems have been increased. The second edition would not have been possible but for the support of Ms. I am grateful to her for making this edition possible. I hope and wish this second edition also will receive the overwhelming support from under-graduate, post-graduate and practising engineers, The author will be grateful for any constructive criticism for the improvement in future editions.

Keeping this in view, chapters 1 to 15 are framed so that the book will be useful to both undergraduate and postgraduate students as well as to practising engineers. In writing this book, I have kept in mind the tremendous amount of ground, which the student and the practising engineer of today is expected to cover. On this account, the work has been organized to form, it is hoped, a continuous logical narrative.

SI units have been consistently used throughout the book. The book includes a large number of typical worked out examples and several illus- trative Iigures for an casicr understanding of the subject. Exercises have also been provided in various chapters so that the inquisitive student may solve these problems and compare with the answers given. Care has been taken to minimize the errors and typing mistakes. I would be obliged to the readers for finding out any such error and mistake, and would be grateful for any constructive criticism for the improvement of various topics in the book.

It would be impossible to refer in detail to the many persons who have been consulted in the compilation of this work. I am thankful to all my Punctilious and highly Devoted scholars, past and present, who have helped me in various ways in bringing out this book. I may be excused for not naming them individually.

Srinivasa Ran, who spared a great amount of his valuable time in going through the manuscript and discussing various points in each chapter. I wish to thank the Centre for Continuing Education of the Indian Institute of Technology, Madras for their help in the preparation of this book.

But, the great step was taken in this direction when man learned the arl: However, while transforming energy from one form to another, the efficiency of conversion plays an important role.

Thus, thermal energy is converted to mechanical energy in a heat engine. Of the vari- ous types of heat engines, the most widely used ones are the reciprocating internal combustion engine, the gas turbine and the steam tu.

The steam engine is rarely used nowadays. This results in a considerable mechanical simplicity and improved power plant efficiency of the internal combustion engine.

Open Wankel En in men: Steam sz. Also, it has been possible to develop reciprocating internal combustion engines of very small power output power output of even a fraction of a kilowatt with reasonable thermal efficiency and cost. The main disadvantage of this type of engine is the problem of vibration caused by the reciprocating oomponents. These fuels are relatively more expensive.

Considering all the above factors the reciprocating internal oombiistion engines have been found suitable for use in automobiles, motor—cycles and Introduction 3 scooters, power boats, ships, slow speed aircraft, locomotives and power units of relatively small output. There are hundreds of compo- nents which have to perform their functions satisfactorily to produce out- put power. There are two types of engines, viz. Let us now go through the important engine components and the nomenclature associated with an engine.

Cylinder Block: The cylinder block is the main supporting structure for the various components. The cylinder of a multicylinder engine are cast as a singlc unit, called cylinder block.

The cylinder head is mounted on the cylinder block. Cylinder head gasket is incorporated between the cylinder block and cylinder head. The cylinder head is held tight to the cylinder block by number of bolts or studs. The bottom portion of the cylinder block is called crankcase. A cover called crankcase which becomes a sump for lubricating oil is fastened to the bottom of the crankcase. As the name implies it is a cylindrical vessel or space in which the piston makes a reciprocating motion.

The cylinder is supported in the cylinder block. It fits perfectly snugly It is the dead centre when the piston is farthest from the crankshaft.

It is the dead centre when the piston is nearest to the crankshaft. Displacement or Swept Volume V,: The nominal volume swept by the working piston when travelling from one dead centre to the other is called the displacement volume.

It is expressed in terms of cubic centimeter cc and given by W V. The displacement volume of a cylinder multiplied by number of cylinders in an engine will give the cubic capacity or the engine capacity. The nominal volume of the combustion cham- ber above the piston when it is at the top dead centre is the clearance volume. It is designated as Va and expressed in cubic centimeter cc.

Compression Ratio r: It is the ratio of the total cylinder volume when the piston is at the bottom dead oentre, V7-, to the clearance volume, Yo. Introduction 7 It is designated by the letter r.

The sequence is quite rigid and cannot be changed. In the following sections the working principle of both SI and CI engines is described. The credit of inventing the spark-ignition engine goes to Nicolaus A.

Otto whereas compression-ignition engine was invented by Rudolf Diesel Therefore, they are often referred to as Otto engine and Diesel engine. The cycle of operation for an ideal four-stroke SI engine consists of the following four strokes 2 i auction or intake stroke; ii compression stroke; iii expansion or power stroke and iv exhaust stroke. The details of various processes of a four-stroke spark-ignition engine with overhead valves are shown in Fig.

When the engine completes all the five events under ideal cycle mode, the p-V diagram will be as shown in Fig. Due to the suction created by the motion of the piston towards the bottom dead centre, the charge consisting of fuel-air mix ture is drawn into the cylinder. When the piston reaches the bottom dead centre the suction stroke ends and the inlet valve closes.

During this stroke both inlet and exhaust valves are in closed position, Fig.

The mixture which fills the entire cylin- der volume is now compressed into the clearance volume. At the end of the compression stroke the mixture is ignited with the help of a spark plug located on the cylinder head. In ideal engines it is assumed that burning takes place instantaneously when the piston is at the top dead centre and hence the burning process can be approximated as heat addition at constant volume. The pres- sure at the end of the combustion process is considerably increased due to the heat release from the fuel.

Expansion or Power Stroke: Both the valves are in closed position, Fig. Of the four-strokes only during this stroke power is produced. Both pressure and temperature decrease during expansion. At the end of the expansion stroke the exhaust valve opens and the inlet valve remains closed, Fig.

The pressure falls to atmospheric level a. The piston starts moving from the bottom dead centre to top dead centre stroke , Fig. The exhaust valve closes when the piston In trad uc tion 9 reaches TDC. These residual gases mix with the fresh charge coming in during the following cycle, forming its working fluid.

Each cylinder of a four- stroke engine completes the above four operations in two engine rev- olutions, one revolution of the crankshaft occurs during the suction and compression strokes and the second revolution during the power and exhaust strokes. Thus for one complete cycle there is only one power stroke while the crankshaft turns by two revolutions. So one should be careful in drawing the ideal p-V diagram Fig. The compression ratio of an SI engine is between 6 and 10 while for a Cl engine it is from 16 to In CI engines, a high pressure fuel pump and an injector are provided to inject the fuel into the combustion chamber.

The carburettor and ignition system necessary in the SI engine are not required in the Cl engine. The ideal sequence of operations for the four-stroke CI engine as shown in Fig.

Air alone is inducted during the suction stick: Air inducted during the suction stroke is com- pressed into the clearance volume. Both valves remain closed durmg this stroke, Fig. Expansion Stroke: Riel injectiolnpstarts nearly at the end of the compression stroke. The rate of miection is such that combustion maintains the pressure constant in spite of thevpiston movement on its expansion stroke increasing the volume.

I-Ieatis assumed to have been added at constant pressure. After the injection of fuel is completed is. Both the valves remain clnsed during the expansion stroke, Fig. The exhaust valve is open an t B intake valve is closed during this stroke. This results in a CI engine being heavier than the SI engine.

However, in both SI and CI engines operating on four-stroke cycle, power can be obtained only in every two revolution of the crankshaft.

Re: I. C. Engines by Ganesan

Since both SI and CI engines have much in common, it is worthwhile to compare them based on important parameters hke basic cycle of operation, fuel induction, compression ratio etc.

The detailed comparison is given in Table 1. In such an arrangement, theoretically the power output of the engine can be doubled for the same speed compared to a four-stroke engine. In twostroke engines the cycle is completed in one revolution of the crsiikshaft.

The induction of the compressed charge moves out the product of combustion through exhaust ports.However, in both SI and CI engines operating on four-stroke cycle, power can be obtained only in every two revolution of the crankshaft.
