| Interview Question | Key Points for Answer |
|---|---|
| What is the working principle of a diesel engine? | Compression ignition (CI) principle – air is compressed to high pressure causing heat, then diesel fuel is injected and ignites. 4-stroke cycle: Intake, Compression, Power, Exhaust. |
| What are the types of fuel injection systems? | Inline injection pump, distributor pump (rotary), unit injectors, common rail direct injection (CRDI). Explain pressure ranges and working of each. |
| What is the difference between diesel and petrol engines? | Diesel: compression ignition, higher compression ratio (14:1 to 25:1), no spark plug, more torque, better fuel efficiency. Petrol: spark ignition, lower compression ratio, spark plugs required. |
| How do you diagnose a diesel engine that doesn’t start? | Check fuel supply, check glow plugs/pre-heating system, check battery and starter motor, check air intake, check compression, check fuel injection timing. |
| What is turbocharging? How does a turbocharger work? | Uses exhaust gas energy to drive a turbine which compresses intake air, increasing oxygen supply and engine power output. Components: turbine wheel, compressor wheel, wastegate. |
| What is the function of a fuel injection pump? | Delivers precise measured quantities of fuel at high pressure to injectors at the correct timing for each cylinder during the power stroke. |
| What are the types of hydraulic pumps? | Gear pump, vane pump, piston pump (axial and radial). Describe working of each and typical application. |
| What safety precautions do you follow in a diesel workshop? | PPE (gloves, safety glasses, boots), proper ventilation, no smoking near fuel, proper lifting techniques, safe use of jacks and stands, fire extinguisher availability. |
| Skill Category | Key Skills Required |
