About this book

The aim of this work, consisting of 9 individual, self-contained booklets, is to describe commercial vehicle technology in a way that is clear, concise and illustrative. Compact and easy to understand, it provides an overview of the technology that goes into modern commercial vehicles.

Starting from the customer's fundamental requirements, the characteristics and systems that define the design of the vehicles are presented knowledgeably in a series of articles, each of which can be read and studied on their own.

This volume, The Diesel Engine, provides an initial overview of the vast topic that is the diesel engine. It offers basic information about the mechanical functioning of the engine. The integration of the engine in the vehicle and major systems such as the cooling system, the fuel system and the exhaust gas treatment system are explained so that readers in training and in a practical setting may gain an understanding of the diesel engine.

Table of Contents

Frontmatter

Chapter 1. Introduction

Abstract
The undisputed king of commercial vehicle engines is the diesel internal combustion engine. In the diesel engine combustion chamber, a diesel air mixture is ignited. In this process, the chemical energy of the diesel is first converted into heat, then this heat is converted into mechanical energy.
Michael Hilgers, Wilfried Achenbach

Chapter 2. Diesel Fuel and Air

Abstract
We will first turn our attention to the energy source: diesel fuel.
Michael Hilgers, Wilfried Achenbach

Chapter 3. The Mechanics of the Engine

Abstract
The heart of the engine is the engine block or cylinder block. This accommodates the crank assembly.
Michael Hilgers, Wilfried Achenbach

Chapter 4. Integrating the Engine in the Vehicle

Abstract
The diesel engine must be integrated in the vehicle. It has many connection points with other vehicle systems, as is shown schematically in Fig. 4.1. For each of these interfaces, the requirements that must be met from both system connected must be defined during development of the vehicle.
Michael Hilgers, Wilfried Achenbach

Chapter 5. The Fuel System and Fuel Injection

Abstract
The fuel system consists of a low-pressure part and a high-pressure part. The low-pressure part includes the fuel tank, a fuel pump, the fuel filter and the low-pressure lines. The fuel filter in the low-pressure fuel system filters particles out of the fuel.
Michael Hilgers, Wilfried Achenbach

Chapter 6. The Exhaust System

Abstract
The exhaust gas which is expelled from the combustion chamber in the fourth stroke is forced out of the engine through the cylinder head and the exhaust manifold. When it leaves the combustion chambers, the discharged gas still contains valuable energy. It is the task of the exhaust gas turbocharger to recover this energy.
Michael Hilgers, Wilfried Achenbach

Chapter 7. Thermodynamics

Abstract
Thermodynamics describes the process by which one form of energy is converted into another. Heat as a form of energy is a central aspect of the subject. With reference to the internal combustion engine, the conversion of the chemical energy in the fuel to the thermal energy of combustion, and finally to mechanical energy is a thermodynamic process. The internal combustion engine is a thermodynamic machine.
