नमूना प्रश्न
अभ्यास कैसे काम करता है, यह जानने के लिए एक उत्तर चुनें और व्याख्या देखें।
A wet-sleeve engine shows small pits on the outside of several liners and the coolant conditioner level is low. The driver reports no overheating. What failure mode is being prevented by correcting coolant chemistry?
A truck returns after an injector replacement with rough idle and no active DTCs. The work order shows the injector trim/calibration code was not entered. Fuel pressure, compression, and harness checks are normal. What should the technician do next?
A six-cylinder diesel has a new vibration at idle after an injector harness repair. Cylinder cutout shows cylinder 5 contributes less than the others. Relative compression is even, fuel rail pressure tracks desired, and wiggling the valve-cover harness changes the miss. What should be inspected next?
A truck has high NOx after SCR service. DEF quality is correct, the DEF doser quantity test passes, and the downstream NOx sensor reports nearly the same value as upstream during a loaded road test. Exhaust leaks are found between the DPF outlet and SCR inlet. What should be repaired first?
An engine has low oil pressure at hot idle after an oil cooler replacement. Pressure is normal cold, the correct oil grade is installed, and no bearing knock is heard. A mechanical gauge confirms the dash reading. Which overlooked item could cause this condition?
