The pre-heat and indicator circuit of Nanjing Iveco light car

Published:2011/7/14 5:08:00 Author:Borg | Keyword: indicator circuit, light car

The pre-heat and indicator circuit of Nanjing Iveco light carWhen the engine water temperature is over 2℃, the system is not working. At the moment, the igniting switch is pulled to MAR gear, the pre-heat indicator 58101(with fuse mark) is only light 2S, or the indicator is put out, then the drive can start the engine. Then pull the key to the starting gear (AVV), the diesel engine is ignited immediately. If the engine water temperature is lower 2℃, the pre-heat system is working, the e-control box makes the indicator 58101 glow continuously for 35~40S, the fire injector is connected and heating. The lower the water temperature is, the longer the heating time is.   (View)

Power Frequency Noise Filter Circuit

Published:2011/7/14 0:57:00 Author:Joyce | Keyword: Power , Frequency , Noise , Filter

As shown in the figure is a power frequency noise filter circuit. This circuit shows a kind of double T filter, which can filter out noise of 50 Hz (or60 Hz) power frequency when magnifying (such as sensors etc) weak signals . If this sort of filters constitutes of RC components only, the value of Q is generally low, and it will have attenuation characteristics like that of the broadband. Using op-amp and add positive feedback can improve the value of Q. supposing that the value of Q is Q ', then Q '= Q / (1 - K), in which, K = RA / (RA RB). Changing coefficient K would increase the value of Q. The resonance frequency of the circuit fo is 1/2 πRC,and the positive feedback components are R / 2 and 2 C.   (View)

Circuit of a Filter with 4 Characteristics Simultaneously

Published:2011/7/14 1:12:00 Author:Joyce | Keyword: Filter , Characteristics , Simultaneously

As shown in the figure is a filter circuit with four characteristics at the same time, that is band-pass (BPF), low pass (LPF), high pass (HPF) and elimination (BEF). This circuit is composed of 4 op-amps .The center frequency f0 is decided by RF and CF,as in the formula f0 = 1/2π RFCF.The value of Q in the circuit is decided by R5 / R2 ,and the gain is decided by R2 / R1. R5 = 10 k Ω, therefore when Q = 1,the output for BPF, LPF and HPF is 0 dB. When input is sine wave, output of BEF is 0, and other filters output the same voltage.   (View)
