An automobile fuel injector system is depicted in Figure P10.37(a). The internal circuitry of the injector can be modeled as shown in Figure P10.37(b). The injector will inject gasoline into the intake manifold when Iinj ? 0.1 A. A voltage pulse train vsignal is shown in Figure P10.37(c). For a cold engine at start-up, the pulse width ? is determined by:
? = BIT × KC + VCIT where
BIT = basic injection time = 1 ms
KC = compensation constant of temperature of coolant (TC )
VCIT = voltage-compensated injection time
The characteristics of VCIT and KC are shown in Figure P10.37(d). Assume the transistor Q1 saturates at VCE = 0.3 V and VBE = 0.9 V. Find the period of the fuel injector pulse if:
a. Vbatt = 13 V, TC = 100°C
b. Vbatt = 8.6 V, TC = 20°C
A Darlington pair of transistors is shown in Figure P10.39. The transistor parameters for large-signal operation are Q1: ? = 130; Q2: ? = 70. Calculate the overall current gain.
