Ayuda para tareas de ingeniería
Diseñado para ingenieros estructurales de primera línea que trabajan en el campo, la ayuda de asignación de ingeniería espera ayudar a los ingenieros de todos los campos en su trabajo.
Contiene varias ayudas de cálculo, procesos de cálculo y métodos operativos que son efectivos en el trabajo diario del proceso de cálculo para producir datos rápidamente. Con funciones integrales de cálculo y consulta, los usuarios pueden buscar requisitos operativos relevantes de acuerdo con las necesidades reales y producir valiosos datos de ingeniería.
- Which of the following should be the first step in diagnosing an engine performance concern? Retrieve diagnostic trouble codes Discussing concern with the vehicle owner Check for symptoms in the on-line service manual Road test the vehicle
- A customer complains that their vehicle cranks but does not start. A scan tool reveals a P0335 (Crankshaft Position Sensor Circuit Malfunction) trouble code. Technician A says that a faulty CKP sensor can prevent the engine from starting because the ECM won't receive crankshaft position data to trigger spark and fuel injection Technician B says that if the CMP sensor fails, the engine may still start but could experience extended cranking ,rough idle, or improper fuel injection timing. Technician A Technician B Both A and B Neither A nor B
- The automotive EVAP system is critically important for safety and emissions. What is the primary function of the EVAP system in automotive vehicles? To recirculated the air in the fuel tank and send to the engine to be used. To help the engine run smoother at higher RPM's by regulating pressure. To stop gasoline fumes from leaking into the atmosphere. To help the engine exhaust to exit the engine better allowing better emissions.
- Technician A states that the air/fuel ratio sensor is located on the engine. Technician B states that the air/fuel sensor is located in the exhaust before the catalytic converter. Who is correct? Technician A Technician B Both A and B Neithers A nor B
- Technician A says that the best way to diagnose an EVAP system leak is to use a smoke machine to introduce vapor into the system and visually inspect for leaks. Technician B says that a loose or faulty gas cap can trigger an EVAP system leak code and should be checked first before performing more advanced diagnostics. Who is correct? Technician A Technician B Both A and B Neither A nor B
