TS 12373

TS 12373 is a vocational standard that defines the repairman for gasoline engines and sets out the professional profile through classification, required knowledge, skills, and the tools, instruments, and equipment associated with the occupation. In automotive service work, a gasoline engine is a coordinated mechanical and electrical system involving ignition, fuel supply, air intake, lubrication, and cooling. The standard focuses on the competencies expected from the person who maintains and repairs that system.

Technical scope of the occupation

The scope covers the description and classification of the gasoline engine repairman, as well as the tools, instruments, and equipment to be used. It also addresses the knowledge and skills each grade or class within the occupation needs to have. In practical terms, this means the role is not limited to disassembly and reassembly; it also involves fault finding, proper measurement, correct use of service tools, and understanding how engine subsystems affect one another.

Core areas in gasoline engine repair work

• Understanding ignition and fuel system components and distinguishing common faults
• Diagnosing wear, clearance issues, and adjustment problems in mechanical parts
• Using hand tools, test instruments, and service equipment for measurement and inspection
• Carrying out maintenance and repair with proper workmanship and safe workshop practice

From a general technical perspective, gasoline engine repair requires the technician to evaluate interconnected subsystems as a whole, because performance and drivability depend on their combined condition. This makes the standard relevant both to theoretical occupational knowledge and to hands-on workshop competence. TS 12373 serves as a reference for the professional profile of personnel working in gasoline engine service and maintenance environments.
