Moteurs diesel : revues techniques (2/2)

Systèmes d'injection diesel - Common-rail et injecteur pompe (2ème édition)

Le système d'injection à rampe commune, dit système Common-Rail, se distingue par la présence d'un seul accumulateur à haute pression qui permet d'alimenter les injecteurs.
Cette technique marque la naissance d'une nouvelle génération de moteurs diesel qui offrent des performances remarquables que ce soit en terme de rendement ou de consommation.

Contrairement aux moteurs classiques, la pompe d'injection est remplacée par une pompe à haute pression. Par ailleurs, une rampe commune permet d'alimenter directement les injecteurs qui sont pilotés électroniquement par un calculateur d'injection. Le contrôle électronique de cette opération permet d'optimiser le fonctionnement de la machine et ce, en déterminant avec exactitude le volume de carburant à utiliser ainsi que la durée de l'injection.

La technique de pré-injection qui caractérise ces moteurs, leur permet de fonctionner silencieusement, tout en réduisant la consommation de carburant. Ce livre vous guide pour vérifier, avec multimètre et oscilloscope, le bon fonctionnement de votre moteur. Ce document, enrichi par des schémas de démonstration, traite près de 60 symptômes et pannes fréquentes qui concernent le système d'injection à rampe commune.

Cet ouvrage contient des chapitres décrivant :
- le fonctionnement des systèmes d'injection
- la vérification avec multimètre et oscilloscope
- les fonctions additionnelles et diagnostic EOBD
- les systèmes anti-pollution et catalyseurs
- 60 symptômes et pannes fréquentes.

Light Duty Diesels (Modern Diesel Technology)

This book provides a thorough introduction to the light-duty diesel engine, now the power plant of choice in pickup trucks and automobiles to optimize fuel efficiency and longevity. While the major emphasis is on highway usage, author Sean Bennett also covers small stationary and mobile off-highway diesels. Using a modularized structure, Bennett helps the reader achieve a conceptual grounding in diesel engine technology.

After exploring the tools required to achieve hands-on technical competency, the text explores major engine subsystems and fuel management systems used over the past decade, including the common rail fuel systems that manage almost all current light duty diesel engines.

In addition, this text covers engine management systems, computer controls, multiplexing electronics, diesel emissions and the means used to control them. All generations of CAN-bus technology are examined, including the latest automotive CAN-C multiplexing and the basics of network bus troubleshooting.

ASE A-9 certification learning objectives are addressed in detail.

High-Performance Diesel Builder's Guide - GM, Ford & Dodge

The first book to explain how modern diesel engines work and how to safely enhance power and performance. The book covers all aspects of the modern turbocharged diesel engine: intake system, camshaft, cylinder heads, fuel system, combustion chambers, transmissions, and gearing.

In addition, this book provides advice on many aspects of tuning your diesel engine from Gale Banks. Author Joe Pettitt, Banks, and other industry experts guide novice and expert diesel enthusiasts alike.
The book covers airflow components, including the turbocharger and intercooler, using electronic tuners, and choosing between nitrous oxide and propane injection.
An in-depth chapter focuses on engine thermodynamics, using simple terms, diagrams, and charts to explain and illustrate the concepts and principles.

Popular turbo diesel engines are covered including Ford Power Stroke, GM Duramax, and Dodge Cummins B and ISB.

Dieselinspuitsystemen met Unit Injector System / Unit Pump System

The Unit Injector System is able to inject the fuel into each cylinder individually, under very high pressure, at the right time and in the right quantity. This results in significantly better combustion than with conventional injection systems. This means more power, lower fuel consumption and lower emissions of harmful substances and less noise development.

With the help of this Dutch technical course, you will learn about the pump injector system for passenger cars and commercial vehicles, as well as the Unit Pump System, also known as the pump line system, for commercial vehicles. You will see how the components function and work together.
The operation and construction of the high-pressure injection, the electronic control and the sensors are described in detail.

Contents:
- Diesel combustion
- Diesel injection systems overview
- UIS/UPS system overview
- Unit Injector (UI)
- Unit Pump (UP)
- Injectors and injector holders
- Electronic Diesel Control (EDC)
- Sensors
- Electronic control unit
- Actuators.
