What have you not known until now, which will advance your operation? Do you know how to diagnose a catalytic converter by measuring signals from a lambda sensor? What are all the problems which may cause improper combustion and what is the simplest way to find the problematic component?

Why is this important? The first fuel injection systems were mechanical, followed by combinations of mechanical and electronic, whereas only electronic fuel injection is used nowadays. Injection systems can be classified according to place of injection, thus there are systems with single injection into the intake port, in front of the intake valve and systems for central injection into the common intake manifold. Having in mind that fuel is injected into the intake port, in front of the intake valve, where a working mixture is formed, these systems are indirect. A system of direct injection into the very engine cylinder was also developed end of last century.

What is the training like?For proper and successful injection system diagnostics it is necessary to have a knowledge of all input and output signals as well as of components participating in the operation of the system.

How will you become better in your work after these training sessions? With the introduction of stricter laws on exhaust fume emissions, injection systems are becoming more complex and intricate and the number of system components with a direct and indirect impact on injection keeps increasing on a daily basis. Proper, fast and efficient diagnostics of such systems requires exceptional knowledge of different fields and acquaintance with different systems. Acquaintance with system operation and diagnostics possibilities requires constant and regular advancement.
