Motori a benzina: manuali di messa a punto e modifica (1/2)

Tuning the A-Series Engine (3rd Edition) - The definitive manual on tuning for performance or economy

Pendant 30 ans, le moteur de la série A a été utilisé par BMC (et plus tard British Leyland) dans de nombreux modèles, notamment les Austin A30, A35, A40/Metro, Allegro, Maestro, Montego/Austin-Healey Sprite/BLMC 1100, 1300/MG Midget / Mini / Morris 1000, Minor et Marina. Il est vite devenu évident que cette série de motos populaire avait encore beaucoup de réserves à améliorer.

Ce livre de préparation fournit de nombreuses informations sur le réglage du moteur de la série A (803 - 1275 cc), à la fois pour l'économie et les performances. Par exemple, il explique comment un moteur standard de 53 ch avec les modifications nécessaires peut délivrer 138 ch, permettant à une Mini d'accélérer de 0 à 160 km/h en 15 secondes.

• Cet ouvrage de référence largement illustré contient des chapitres sur les filtres à air, les carburateurs, les collecteurs d'admission, les culasses (soupapes, chambres de combustion, modification du taux de compression), les systèmes d'échappement, les arbres à cames (différents profils de came, culbuteurs et poussoirs de soupape), les soupapes forcées l'induction (turbos, compresseurs mécaniques), le bloc moteur (pistons, bielles, vilebrequin, roulements), l'augmentation de la cylindrée, le système de lubrification (pompe à huile, refroidisseur d'huile), l'allumage et le refroidissement (pompe à eau, thermostat, radiateur) ).
• Ce livre fournit également divers exemples de réglage, des informations sur les installations d'oxyde nitrique (N2O), la mesure de la puissance et le réglage pour l'économie.
• Bien que destiné à la série A, ce livre fournit également de nombreuses informations utiles pour le réglage d'autres moteurs à essence comparables.

David Vizard's How to Port & Flow Test Cylinder Heads

Porting heads is an art and science. It takes a craftsman's touch to shape the surfaces of the head for the optimal flow characteristics and the best performance.
Porting demands the right tools, skills, and application of knowledge. Few other engine builders have the same level of knowledge and skill porting engine heads as David Vizard.

All the aspects of porting stock as well as aftermarket heads in aluminum and cast-iron constructions are covered. Vizard goes into great depth and detail on porting aftermarket heads.

Starting with the basic techniques up to more advanced techniques, you are shown how to port iron and aluminum heads as well as benefits of hand and CNC porting.
You are also shown how to build a high-quality flow bench at home so you can test your work and obtain professional results. Vizard shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber.

The book covers blending the bowls, a basic porting procedure, and also covers pocket porting, porting the intake runners, and many advanced procedures. These advanced procedures include unshrouding valves, porting a shortside turn from the floor of the port down toward the valve seat, and developing the ideal port area and angle. All of these changes combine to produce optimal flow velocity through the engine for maximum power.

Competition Engine Building

The needs of a true competition engine are quite different than those of the engine under the hood of a typical commuter car. From the basic design needs, to the base component materials, to the sizes of the flow-related hardware, to the precision of the machining, to the capabilities of each pertinent system, very few similarities exist.

Many books exist showcasing how to make street-based engines more powerful and/or durable.

This book is different, in that it focuses purely on the needs of high rpm, high durability, high-powered racing engines. It begins by looking at the raw design needs, and then shares how these needs are met at the various phases of an engine's development, assembly, testing and tuning.

This book features reviews of many popular modern tools, techniques, products, and testing/data collecting machinery. Showing the proper way to use such tools, how to accurately collect data, and how to use the data effectively when designing an engine, is critical information not readily available elsewhere.
The special needs of a competition engine aren't commonly discussed, and the many secrets competition engine builders hold closely are openly shared on the pages here.

Authored by veteran author John Baechtel, Competition Engine Building stands alone as a premier guide for enthusiasts and students of the racing engine. It also serves as a reference guide for experienced professionals anxious to learn the latest techniques or see how the newest tools are used.
Baechtel is more than just an author, as he holds (or has held) several World Records at Bonneville. Additionally, his engines have won countless races in many disciplines, including road racing and drag racing.

Engine Blueprinting Techniques - A Practical Guide to Precision Engine Building

Engines are built to fall within a wide set of standards and specifications, often not optimized to meet the original design. In short, cheap and fast engine production results in a sloppy final product. Of course, this is not idea for high-performance engines.

To maximize the performance of any engine, it must be balanced and blueprinted to the exact tolerances that the factory should have adhered to in the first place. Four cylinder, V-8, American or import, the performance of all engines is greatly improved by balancing and blueprinting. Dedicated enthusiasts and professional racers balance and blueprint their engines because the engines will produce more horsepower and torque, more efficiently use fuel, run cooler and last longer.

In this book, expert engine builder and veteran author Mike Mavrigian explains and illustrates the most discriminating engine building techniques, so the engine is perfectly balanced, matched, and optimized. Balancing and blueprinting is a time consuming and exacting process, but the investment in time pays off with superior performance.

Through the process, you carefully measure, adjust, machine and fit each part together with precision tolerances, optimizing the design and maximizing performance. The book covers the block, crankshaft, connecting rods, pistons, cylinder heads, intake manifolds, camshaft, measuring tools and final assembly techniques. It provides an unprecedented level of detail and instruction on the process of balancing and blueprinting your engine.

Praxishandbuch Nockenwellen - Verstehen, Pflegen, Optimieren

How sharp can it be? Anyone who prepares an engine - whether to seriously tune it or simply to get the best out of the standard machine - cannot avoid the subject of valve control. The pivotal point in the four-stroke engine is the camshaft. They are available from mild to sharp, from brand new to reconditioned.

Des Hammill, engineer and experienced professional racing engine builder, knows what is important. In this practical manual from the Oldtimer Markt edition, he reveals how to find the right shaft, how to set up the control correctly and how to test it.
If your engine still doesn't run after tuning despite following the tips in this book, then it is definitely not the camshaft.
