Systèmes d'allumage : manuels - entretien et réparation

A lot is talked about ignition systems, and there is a bewildering choice of expensive aftermarket parts, which all claim to deliver more power. Des Hammill cuts through the myth and hyperbole and tells readers what really works, so that they can build an excellent system without wasting money on parts and systems that simply don't deliver.

Ignition timing and advance curves for modified engines is another minefield for the inexperienced, but Des uses his expert knowledge to tell readers how to optimise the ignition timing of any high-performance engine.

The book applies to all four-stroke gasoline/petrol engines with distributor-type ignition systems, including those using electronic ignition modules: it does not cover engines controlled by ECUs (electronic control units).

A guide to ignition and timing, for classic car owners and restorers. Aimed at both keen amateurs and professionals alike, "Ignition and Timing" covers the history and evolution of the automotive ignition system, and how to fit, modify and maintain your system for optimum timing and maximum performance.

Topics covered include:
- Post-war distributors and aftermarket systems
- Understanding and fault-testing the coil ignition system
- How to fit electronic ignitions and modify the distributor, including twin-point distributors
- Rebuilding and maintenance
- Lucas, Delco and Bosch systems
- Identification charts for your distributor
- How to achieve optimum timing and how to use a timing light.

Performance modification on enthusiast cars and trucks entails the modification of many systems in concert with each other. Induction systems, exhaust, rotating assemblies, cylinder head modification, all areas where modifications yield exciting and measurable results.
While decidedly not as sexy to most, ignition systems are just as important as all of the other systems, and modifying your ignition system is vital in extracting all the performance possible out of your engine build. What good is air flow if your ignition system can't light the fire?

This is a completely updated guide to understanding automotive ignition systems, from old-school points and condensers to modern computer-controlled distributorless systems, and from bone-stock systems to highly modified.

Author Todd Ryden leads you through the various components in this update, explaining the theory behind the operation and how the parts work with each other to achieve the ultimate goal of efficient combustion.
The inside scoop on all the new coils, wires, spark plugs, distributors, magnetos, inductive systems, CD ignitions, multiple-spark systems, computer ignition controls, rev limiters - all are covered for both street and race applications.
