Summary of change:
Small (appr 4 liter) gas engine, '''4 cylinder''', 1500 RPM (some comments on this page are Hungarian) ---- '''Grounds''' * EC36/5 * EC36/21 * EC36/22 * EC36/32 * EC36/26 See MembersPage/PhatBob/UserGuide ---- '''Supply +12V or +13.5V''' (not +24V !!!) * EC36/25 (1-3A fuse, if stepper output not used) ---- '''Sensors''' '''5 EGT''' (order comment: "5 EGT inputs") 4 individual + 1 mixed * K-compensation cable (kompenzációs kábellel bekötni) '''CLT''' Coolant Temperature (hengerfej víz temperature) * EC36/14 (és a GND közé) '''MAT''' Manifold Air Temperature (gázkeverék temperature osztócsoben) 0-5V signal * EC36/2 (és a GND közé) not K-type ** to use with K-type (eg. EGT2 mcp3208/ch4) firmware modification would be needed... (maybe some special case of the 17-point curve, the 1000C area obviously won't be used) '''TPS''' (folytószelep pozíció) * EC36/1 (0-5V analog) '''MAP''' : Manifold Absolute Pressure, pneumatic connector (szívócsonyomás, abszolút 0-300 kPa ?) ---- '''Trigger input''' * EC36/27 Primary trigger, HALL 8-1 (or 12-1 or 12-2) ** configurable rising (felfutó) or falling (lefutó) edge ** after missing tooth, recommended pulse positions: 40-60 and 10-20 crankdegrees BTDC (BTDC == fotengely fokkal felso holtpont elott) '''Warning''': since this engine has primary trigger on the camshaft, not the crankshaft as usual, '''6-1 is not suitable, only 8-1''' or 12-1 or 12-2 (or some even higher toothcount). * '''NO EC36/13 Secondary trigger:''' HALL, 0 pulse ** configurable rising (felfutó) or falling (lefutó) edge ** (vezermutengely jelado, a fotengely hianyzo fogatol legalabb 70 fokra) EC36/28: +5V output for HALL sensors ('''max 50mA''' recommended) ---- '''Ignition outputs''' (1,3,4,2 firing order) * EC36/34 (IGN/2) cyl1 * EC36/36 (IGN/3) cyl3 * EC36/24 (IGN/6) cyl4 * EC36/10 (IGN/7) cyl2 4A biztosítékon át a gyújtótrafó másik vége tápfeszre (+12V vagy +24V DC) van kötve '''Starter config''' * Primtrig 8-1 on cam, next_trigger_tooth=2, ignouts: 2,3,6,7 appr. 2.2 msec dwell * fuelcut 1600, igncut 1700 RPM. They 'll have to adjust primtrig/rising/falling and TDC-delay of course. * Maybe we need to cheat with the cylnr=2 (not 4) so that "double RPM" is shown so RPM shown correctly (8-1 on cam) * req_fuel=16msec, VE=200 (near flat, or minor grassy knoll) because at 1500 RPM (80 msec / camrot) '''32msec''' = 40% duty=8kW / 20kW ** with LPG, it should idle between 32 and 40 msec * CLT and MAT enrichment all 100% for now ---- '''IAC PWM output''' Possible PWM voltage for Woodward 5-32VDC * Power Throttle Valve (teljesítmény pillangószelep) ** TPS in EC36/1 0,75-4,25VDC CORRECT?? ** 0-90% (or 10-90% ) ** EC36/pin11 (ign4) 0/5V ('''max: 1.1mA''') ** alternatively: EC18/pin4 (Stepper A) 0/12V Woodwars spec: PWM Command Input (+PWM at pin 11, PWM ground at pin 3)—This actuator can be configured to handle a PWM signal from a high-side or low-side opencollector or open-drain source, as well as from a push-pull (customer pull-up) source. The necessary pull-up and pull-down voltages to accommodate the open-collector sources are handled within the L-Series actuator. Nominally, the frequency of PWM is 1 kHz, but it will handle the full range of 300 to 1500 Hz. See Figure 3-5 below, which describes the possible input types and configurations for the PWM input. ---- '''Mixture valve''' * PWM or 0-5V analog signal (with RC filtering): ** EC36/12 (ign/5 logiclevel). Low current signal, do not load. ('''max: 1.1mA''') '''Alternatively:''' * Or EC36/7 injch/1 (ez a kimenet külso felhúzót igényel, max 30V-ra mivel ez a kimenet csak földre húz). ** EC36/23 Flyback = +12V (or +24V) -ra is be kell kötni az induktív terhelés tápját, ha induktív terhelés van valamelyik injch-n (EC36/6,7,8,9,17,18,19,20) pl. mágnesszelep vagy gázinjektor ---- '''2nd RS232''' for CRC protected special commands 2nd RS232TX (EC18/14) 2nd RS232RX (EC18/15) GND 2nd RS232TX (EC18/6) 2nd RS232RX (EC18/12) GND * Modbus RTU 9600-38400(115200?),8n1 recommended, configurable up to 115200,8n1 (8e1 also possible, but rarely used) * Modbus address configurable (2 in the examples: ALS_deactivation time=0.2 sec means modbus address=2) '''Examples:''' (02) 06 00 XX VV 00 (CRC CRC) '''XX table:''' * 0x31 iac forced pw = VV ** IAC PWM output * 0x34 debug.forced_boost_tgt = VV ** boost target (2kPa) * 0x35 lambda target = VV ** needs negotiation (egyeztetés szükséges) Register/Address for reading/writing ?? read: - lambda érték - fojtó állás - kipugáz hőm. - kopogás mértéke - hibák - szívócső hőmérséklet - gyújtásszög - fordulatszám - gázkeverő parancsolt érték - gyújtás kihagyás - fojtó parancsolt write: - alap gyújtásszög - lambda SP - fojtó parancsolt ---- K-Thermocouple * EGT1 (mcp3208/4) used for EGT * EGT2 (mcp3208/3) used for MAT * EGT3 (mcp3208/..) used for (engine inlet water temperature) * EGT4 (mcp3208/..) used for (engine outlet water temperature) ---- WBO sensor connection * 7 WBO2 Pump- * 9 WBO2 Pump+ * 13 WBO2 Nerst signal * 17 WBO2 Ground * 18 WBO2 Heater ---- Digital inputs * Generator mains paralell mode ON (1=GCB closed/0=GCB open) * From Standby to ready to start (1=ready/0=standby) ---- Digital output * ECU ok (1=ok/0=fail or not ready) (in stanby ECU this signal=0) ---- Knock sensor 1pcs. * EC18/6 and GND
