Engine electric equipment
The general information and safety measures
The structure of an electric equipment of the engine includes components of systems of ignition, a charge and start. Whereas the given systems have a direct bearing on engine work, they are considered separately from an other onboard electric equipment, such as alarm and lighting fires, monitors, etc., to placing, a design and to which principles of functioning the Chapter the Onboard electric equipment is devoted. As the electronic control system of the petrol engine exercises administration of functioning not only fuel injection, but also ignition of a mix (ignition), the description of main principles of its action also is included in the given Chapter (the Electronic control system of ignition (and injection) petrol engines see).
At service of components of systems of an electric equipment it is necessary to observe special safety measures in order to avoid risk of failure of semi-conductor elements, and also for the purpose of reception prevention элеткротравм.
Starting electric equipment service, necessarily remove a watch, rings and other metal ornaments. Even at the disconnected battery the category of condensers at casual grounding of their plugs can lead to reception of an electric shock or a strong burn.
Do not suppose polarity infringement at battery connection. In structure of such components as the generator, or electronic blocks of management enter semi-conductor elements which can be put out of action at wrong connection of wires.
At performance of start of the engine from the external power supply, or connection зарядного devices also observe polarity of connection of wires (Introduction see).
Never disconnect electroconducting from the battery, the generator or the diagnostic equipment at the working engine.
Do not suppose проворачивания the engine of the disconnected generator.
At all do not make stock-taking of target pressure of the generator by grounding of its plugs.
Do not apply to conductivity stock-taking in a chain the ohmmeters equipped manual dynamo-car.
At performance of any works on electric equipment service watch, that the negative wire has been disconnected from the battery.
Before use of electroarc welding without fail disconnect the battery, the generator and such components, as ECM systems of a food/ignition in order to avoid risk of their damage.
