microcontroller ignition system (from Zündanlage... tema)

Zitat von Ilegal

just wanted to know whether you still have temperatures below 0 degrees Centigrade - ie is it still freezing where you live ? Just out of curiousity, no deeper sense,wondering,you know ?

ah, ok. this is strange question, in this case firstly I not understand you question :)
The question essence is not clear for me, as at us should be winter. A polar circle nearby.
I will answer in detail and, I hope, clearly. :)

today -19..-21 humidity 99%
for SPB this is normal temp, and see to humidity, if you understand, what this mean in that temperature.
Mid-annual temperature: +5.4
also, for us temperature jumping are normal, one day -20, next day -3, etc.
temperature values for winter: +8...-42, with humidity 99%.
winter starts at ~second half october, ends at may, but snow can come in june. absolute maximum of summer temperature +35.
warm (+5..+30, humidity 99%) temperature from second half of may up to second haft of september,
>+20 ~2 months in summer. 62 sunny days per year.
temp difference btw city center and suburb can be up to 10 degrees.
:)

MICROPROCESSOR-BASED IGNITION SYSTEM
Carburetor engines.
"MPSZ-ZH"

GUIDELINES FOR THE INSTALLATION AND OPERATION.
This instruction applies to microprocessor ignition system «MPSZ-ZH» (hereinafter MPSZ), designed for operation with petrol engines.
Electrical connections to the car with an installed microprocessor ignition system «MPSZ-ZH» given in Annex A.
1. APPOINTMENT AND COMPOSITION OF THE SYSTEM
The «MPSZ-ZH» is designed for precision forming ignition timings angles of four-stroke gasoline engines, depending on speed, engine load and the detonation.
Formation of ignition angles (hereinafter - ISP) is recorded in the controller memory: MPSZ sets of parametric tables (hereinafter POPs).
The MPSZ-ZH may be installed instead of the classical ignition system on any car with four-cylinder carburettor engine.
However, it can run on non-contact interrupts distributor, using a Hall sensor, and work with the crankshaft position sensor (CPS).
This system can be used in the ignition system with a classic distributor and systems coupled with ignition coils (each coil runs on two cylinders).
The structure of the microprocessor ignition system consists of:
- Controller plugs MPSZ-ZH -1 pcs;
- On-board computer (optional) -1 pcs;
- Wiring harness to connect sensors (optional) -1 pcs.

The distributor, ignition coil, ignition switch, solenoid valve, installed on the car, and are not included.
Sensors (CPS, KS, MAP) are purchased by the user in the automobile dealer.

2. MAIN CHARACTERISTICS OF THE MAIN FEATURES «MPSZ-ZH»:
o Work with Hall sensor staffing ignition distributer or crankshaft position sensor (CPS);
o The load on the engine is analyzed by the absolute pressure sensor in the intake by MAP sensor;
o Support knock sensor (KS) and automatic correction of POPs in his signal;
o The use of sensors from the widespread injection models of automobiles VAZ and GAZ, available in any automobile;
o 16 sets of working curves ISP, user programmable, while keep in a programmable memory controller, which can switch between on the fly. (2)
o Switching between the two selected sets of curves for the closure of the control input to the "mass" (for example, to realize the function of "gas / petrol), (3)
o A separate customizable curves POPs at start-up engine and idling;
o Support the idle speed. Idle automatically maintaining by the programmed level, regardless of changes in engine load;
o Programmable economizer overrun;
o Built-in variable octan-corrector
o The presence of serial communication port (RS-232) to connect the onboard computer or personal computer (notebook);
o Programming of parameters and control settings MPSZ using the onboard computer MPSZ or connected to a personal computer (notebook);
o The issuance of the protocol and sensor readings to the serial communication port RS-232 (COM port). Displays real-time parameters of the motor on the screen board of onboard computer or connected personal computer (notebook). Recording protocol in LOG-file (when connecting a personal computer (notebook)); Notes:
1) sold separately;
2) using the onboard computer (sold separately) or connected to MPSZ personal computer;
3) Only when running with CPS.

SPECIFICATIONS «MPSZ-ZH»:
Power supply 6 ... 16 V
Engine RPM at which the work is guaranteed 0 ... 15000
Engine RPM at which the adjustable UOZ1 229 ... 7500
The range of formation of POPs -52 ... +60 ° CPR
Correction of POPs in the detonation 0 ...- 100 CPR
Supply current MPSZ + DBP Not more than 0.03 A
Operating temperature range -40 ... +85 ° C
1) At speeds beyond the limits of regulation formed permanent POPs, which he set at the boundaries of regulation;
2) For version DPKV with one coil minimum POPs is -2.
