What is Engine Diagnostics?

Engine diagnostics is a comprehensive scanning and analysis procedure of engine operation and related systems using specialized equipment. It helps identify problems at early stages, determine the cause of malfunction, and prevent costly damage.

Main engine systems:

• Engine Control Unit (ECU) — computer managing engine operation
• Ignition system — ensures engine startup
• Fuel supply system — delivers fuel to cylinders
• Cooling system — regulates engine temperature
• Lubrication system — delivers oil to moving parts
• Exhaust system — removes exhaust gases
• Intake system — delivers air to engine

Why engine diagnostics needed?

• Identify hidden problems before escalation
• Determine exact cause of malfunction
• Save time and money on repairs
• Improve engine performance
• Increase efficiency and safety
• Pass vehicle technical inspection (ITV)
