FOREWORD:

• A good diagnosis is carried out with the competence acquired from years of experience and taking part in repair courses. When a user complains about a bad efficiency or operating anomalies, his indications must be kept into due account, taking from them those useful information that will be used to guide our intervention. After having detected the anomaly, it is advisable to carry out failure search operations by decoding self
•  Diagnosis data of the central electronic unit of theEDC (Engine Diesel Control) system. With the use of computerised tools, it is also possible to establish a bi–directional communication with the central unitwithwhich it is possible not only to decode the error codes, but also to address the image in its memory to obtain those further necessary information to go back to the anomaly origin. Every time an inconvenience occurs and its existence is detected,
• It is necessary to proceed with the electronic unit query through one of the pointed–out ways and then proceed with the diagnostic survey through tests and measures through which an outline of operating conditions is obtained and the real anomaly reasons are identified. In case the electronic unit does not provide indications, one will have to proceed with one’s experience by adopting traditional diagnostic modes.
• The exhaust gases can be partially conveyed back into the cylinders to lower themaximum values of the combustion temperature that are responsible for the production of nitrogen oxides (NOx). The exhaust gas recirculation system (EGR), lowering the combustion temperature by decreasing the concentration of oxygen in the combustion chamber, is therefore an effective system to control the emission of NOx.
• Internal EGR acting on the exhaust valves The internal EGR system, thanks to an appropriate exhaust cam design permits some of the exhaust gases to be reintroduced back into the engine cylinders. This type of EGR, internal EGR is not provided with any electronically controlled element: the system is always on. Its configuration doesn’t need any additional elements such as control valves, pipes or heat exchangers.
• The exhaust cam, besides themain lobe, has an additional lobe (C) compared to the configuration without EGR. During the intake stroke of the cylinder under examination, this lobe permits briefly opening the exhaust valve. In this way, recirculation is generated on the cylinder in the intake stroke due to the greater pressure of the exhaust gases compared to the intake gases.
