7.2. Safety requirements and preventions
Gasoline extremely fire - also is explosive, therefore it is necessary to show care at work with any knots of the power supply system.
Works are necessary for spending in well aired premise, it is better with open windows and дверьми for draught creation.
It is impossible to use open fire, electric welding and the tool, at work with which sparks can be formed. Check up, that in immediate proximity from a workplace there was a charged fire extinguisher.
For protection of eyes against hit in them of fuel use points. At fuel hit on a skin wash out this place a water considerable quantity.
The capacity in which there is a fuel, contains its steams and is potentially explosive.
At work with the power supply system observe cleanliness as the dirt which has got to channels of system, can block them that will break normal work of the engine.
Application of an electronic control system by the engine provides following advantages:
– Thanks to optimum giving of fuel in the engine on all operational modes the fuel expense decreases at preservation of dynamic characteristics of the car;
– Fuller combustion of fuel and use catalytic neutralizer allow to reduce emission of harmful substances with the fulfilled gases;
– As the electronic control system of the engine defines and writes down in memory of malfunction, their search and detection is considerably accelerated;
– The control system of the engine on all operational modes establishes an optimum angle of an advancing of ignition, the moment and quantity of fuel submitted to the engine. The control system of the engine co-operates with other systems of the car, in particular with a control system of an automatic transmission or with anticreeping system.
Elements of a control system of the engine are very reliable and practically do not demand service. At maintenance service it is necessary to replace only the air filter and spark plugs. For check, adjustment and repair of a control system by the engine it is necessary to use the difficult expensive equipment, therefore these works it is necessary to carry out at specialised servicing deport.
While in service the car it is not required to regulate frequency of rotation of idling and the maintenance WITH in the fulfilled gases.
At service and repair of system of ignition of the car at the included ignition it is necessary to be careful, as it is possible to receive blow by a current from a high-voltage part of system of ignition. People with stimulators of warm activity are not recommended to check and repair a control system of the engine. Switch off ignition before a detachment or connection of any element of system of ignition or conclusions of the measuring device.
The fuel system constantly is under pressure even after engine deenergizing, therefore at carrying out of any works on fuel system it is necessary to remove pressure.
For prevention of possibility of casual short circuit in an electric chain and damages of electronic elements of a control system by the engine always remove a wire of "weight" from the storage battery.
Before performance of any works on a control system of the engine cause from memory the malfunctions written down in it. Also check up tightness of power supply systems and air giving in the engine.
If after work on a control system the engine is started up and through short time stops, probably, it is switched off by anticreeping system. In this case cause from memory the malfunctions written down in it and if necessary adjust a control system of the engine.
