Technician A says that fuel injection systems are electronically controlled with variable injection pressure capabilities and with maximum injection pressure reached independent of engine speed. Technician B says that improved atomization requires lower pressurization for improved emissions and performance. Who is right?
A)A only"
B)B only"
C)Both A and B
D)Neither A nor B"

Question

Quizplus · Accepted Answer

Technician A is correct because modern fuel injection systems are electronically controlled and can achieve maximum injection pressure independent of engine speed. Technician B is incorrect because improved atomization typically requires higher, not lower, pressurization for better emissions and performance.
