V. expository questions 45. try to explain the fuel injection device maintenance precautions. p137 A: 1. electronically controlled fuel injection engine itself is the same as ordinary gasoline car maintenance, to be carried out in accordance with the regulations. Therefore, when the engine or car malfunction, the first thing to find out whether the engine or the car itself mechanical failure, if there is no mechanical failure, before the electronic control system can be checked. 2. check the electronic control system, the first application of self-testing system to check the alarm light shows its fault code, and then according to the fault code to identify the parts and nature of the possible occurrence. 3. on the electronic system or components before the specific inspection Before carrying out specific checks on the electronic system or components, the battery cable should be removed first. However, after removing the battery cable, the diagnostic code memorized by the electronic control area device will be automatically cleared, therefore, before removing the line, the fault code should be read with special equipment and instruments. 4. 4. When carrying out the dismantling and checking, we should try to use special tools and special instruments and equipment, and check the table with ordinary instrumentation, and we should pay attention to the power supply voltage used in order to prevent damage to the electronic devices. 5. 5. O-ring sealing rings on the assembly parts such as the injectors are One-time use of parts, can not be reused, must be replaced with new parts to ensure its sealing. 6. electronic control unit is generally very few failures, such as must be checked, to use special instruments and equipment, generally not allowed to dismantle the repair operation. 46. test the types of automotive testing equipment Answer; Vehicle testing can be divided into the vehicle safety and environmental protection and comprehensive testing.
