Neither A nor Barrow_forwardWhile discussing the compression ratios used with engines equipped with a GDI system: Technician A says that higher ratios can be used because ignition timing is normally very advanced. Technician B says that higher ratios are possible because the small droplets of fuel injected directly into the cylinder tend to cool the mixture in the cylinder. Who is correct?a.tech a b.tech b c.

- Tech A says that the weight of the flywheel smoothes out the engine’s power pulses. Tech B says that the flexplate and torque converter perform this same function. Who is correct?arrow_forwardWhile discussing El systems: Technician A says that when the engine is being cranked, the PCM relies only on the signals from the ECT to determine initial ignition timing. Technician B says that when an engine is initially started and is running at a predetermined speed, the PCM looks at several inputs, including engine speed, load, throttle position, and engine coolant temperature, and makes adjustments accordingly. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhile discussing injector testing: Technician A says that a defective injector may cause cylinder misfiring at idle speed. Technician B says that restricted injector tips may result in acceleration stumbles. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forward
