Control system of the engine
On cars Hyundai Getz the electronic control system of the engine, i.e. system of the distributed injection of fuel is applied. Distributed injection is called because for each cylinder fuel is injected by a separate atomizer. The system of injection of fuel allows to lower toxicity of the fulfilled gases at improvement of road performance of the car.
There are systems of the distributed injection with a feedback and without it. In the present section the short description of the general principles of the device, work and repair of systems of injection of fuel is given only.
Engines Hyundai are equipped by a control system with a feedback. In release system it is established каталитический neutralizer and the gauge of concentration of oxygen which provides a feedback. The gauge traces concentration of oxygen in the fulfilled gases, and the controller on its signals supports such parity of air and fuel which provides the most effective work of neutralizer.
In system of injection without a feedback neutralizer and the gauge of concentration of oxygen is not established, and for adjustment of concentration WITH in the fulfilled gases serves With-potentiometer. In this system the system of catching of steams of gasoline is not applied also.

Control lamp of malfunction of a control system of the engine (cars without the European onboard system of diagnostics)
Lighting up, the control lamp warns the driver about malfunction presence in a control system of the engine. However, if the found out malfunction is not shown after three consecutive cycles of work of the engine, the lamp dies away. The lamp lights up right after ignition inclusions (without engine start-up) that specifies in its serviceability.
Conditions, at creation of any of which the control lamp lights up:
– The warmed up gauge of concentration of oxygen is faulty;
– The gauge of absolute pressure is faulty;
– The gauge of position throttle заслонки is faulty ;
– The gauge of temperature of a cooling liquid is faulty ;
– The idling regulator is faulty;
– Atomizers are faulty;
– The engine management block is faulty.
For check be convinced that after inclusion of ignition the lamp burns approximately during 5 with, and then dies away.
If the lamp does not light up, the possible reason is the wire breakage, перегорание a safety lock or the lamp.
Self-diagnostics system
The engine management block gives operating commands on actuation mechanisms and processes signals from gauges (some commands and signals constantly, others – only under certain conditions). If ЭБУ finds out a deviation from norm, he writes down a diagnostic code of malfunction and gives out a signal on a contact socket of a line of data transmission. The result of diagnostics is displayed by fire of a control lamp of malfunction or on device HI-SCAN. Diagnostic codes of malfunction are stored in memory ЭБУ until on it pressure from the storage battery moves. Malfunction codes leave at a detachment of the storage battery or separation of contact socket ЭБУ or are erased by means of diagnostic device HI-SCAN.
|
THE NOTE
At a detachment of a contact socket from any gauge at the included ignition in memory ЭБУ the malfunction code registers. In this case it is necessary to remove a malfunction code, having disconnected a wire from the negative plug («–») the storage battery.
|
Work of onboard system of diagnostics
1. If the same malfunction is found out and remains during two cycles of a trip, the control lamp of malfunction of a control system of the engine automatically lights up.
2. The control lamp of malfunction of a control system of the engine dies away, if during three cycles of successively malfunction are not found out.
3. The diagnostic code of malfunction (DTC) registers in memory ЭБУ at failure detection after two cycles successively. The control lamp of malfunction of a control system of the engine lights up at failure detection in the second cycle.
At detection of the admission of ignition of a mix the malfunction code, and a control lamp of malfunction of a control system of the engine registers lights up right after failure detections.
4. The malfunction code automatically leaves from memory ЭБУ if the same malfunction is not found out during 40 cycles.
|
NOTES
The cycle of warming up of the engine corresponds to sufficient time of its work during which the temperature of a cooling liquid raises from the moment of start-up of the engine not less than on 4,5 °С and reaches values not more low 70 °С.
The trip cycle includes start-up of the engine and movement of the car after the beginning of adjustment of structure of a mix on signals of gauges of concentration of oxygen.

The gauge of absolute pressure
The gauge of absolute pressure (MAP) is executed in the form of the variable resistor sensitive to change of pressure. The gauge measures changes of pressure in the inlet pipeline depending on change of loading and frequency of rotation of a cranked shaft of the engine and will transform them to pressure of a target signal. The gauge measures also barometric pressure at the moment of start-up of the engine and under some conditions provides ЭБУ possibility automatically to be adjusted on different values of height above sea level. ЭБУ submits on the gauge pressure of a food 5 In and processes the signals of the gauge transferred on a chain of a signal transmission. The gauge is connected to "weight" through the built in variable resistor. Depending on gauge EBU signal regulates duration of giving of fuel and a corner of an advancing of ignition.

The gauge of temperature of a cooling liquid is established in the pipeline of a cooling liquid on a head of the block of cylinders. It takes temperature of a cooling liquid and gives out a signal on the engine management block. The gauge is executed in a kind термистора, sensitive to temperature change. Electric resistance of the gauge decreases with rise in temperature. ЭБУ defines temperature of a cooling liquid on value of pressure of a signal of the gauge and establishes optimum enrichment топливовоздушной mixes at engine warming up (fig. 2.219, 2.220).
Check. Remove the gauge of temperature of a cooling liquid from the inlet pipeline.

2. At infringement of work of the engine idling or deterioration of dynamics of dispersal check up connection of a contact socket of the gauge. At bad connection of a contact socket of the gauge the data deduced by device HI-SCAN, can specify in absence of transition to an idling mode at the released pedal of an accelerator. It will lead to infringement of work of the engine idling and to deterioration of dynamics of dispersal.

That it is necessary to know to the owner of the car with инжекторным the engine
Inzhektornye motors surpass carburettor in many parametres, to take at least their profitability and problemless start-up in a frost. Nevertheless carburettor under our conditions sometimes appear more advantageous. Some motor-car manufacturers even deliver on our market cars with such engines. All business in quality of gasoline which sell at us.
The inzhektornyj engine is calculated on high-grade gasoline which on our refuellings you will find infrequently. Besides different systems of injection have the specific features, they are necessary for considering at car operation. And in our market it is a lot of such systems: mechanical –
K-Jetronic (KE-Jetronic), electromechanical – L-Jetronic and electronic – Motronic, Lucas, Magneti Marelli.
Many systems have two operating modes: the basic and emergency, used at malfunction of one of gauges. The driver can and not notice such malfunction: on the panel of devices there is no corresponding control lamp, and the engine continues to work (but any more in an optimum mode). Similar quite often happens on cars Audi equipped with engines with the central injection of fuel. About third of the motorists having such cars, do not guess at all that go in emergency operation. And it conducts to the raised expense of fuel, decrease in capacity, rough work of the engine and the complicated start-up. Malfunction comes to light only at the next maintenance service. Therefore on "the weak" places of systems of injection shown under our conditions, it is necessary to dwell.
Systems with mechanical injection. They in a greater degree, than others, are subject to physical deterioration. The regulator of pressure of fuel refuses usually through 80-120 thousand in km of run (engine start-up considerably worsens), atomizers – through 60-80 thousand in km (rough work of the motor, the raised expense of fuel). Refusal of atomizers is especially artful, as it will notice not at once. For diagnostics and repair the special equipment is required.
Sore point of systems with electromechanical injection – подсос air through the numerous vacuum hoses tending to растрескиванию after 4–5 years of service. Especially on cars VMW and in some smaller degree on Аudi. To define such defect difficult enough.
Electronic systems of injection. At them the problems. For example, the accumulator "has sat down", and you on an old habit have decided to "light" from other car. The electronic block of management of system of injection as a result fails. And application этилированного gasoline, in turn, puts out of commission the gauge of concentration of oxygen (ljambda-probe) and каталитический neutralizer.
As a whole both mechanical, and electronic systems of injection have the pluses and minuses. At mechanical the thicket is refused by gasoline pumps and dozatory-distributors.
At electronic the gasoline pump is more durable and is cheaper, but elimination of any malfunction of the electronic block of management will cost rather expensively. Besides, the reasons for failure of any system at us, alas, more than in Europe: poor-quality gasoline, a dirt on roads and chemicals which strew in the winter. Therefore it is necessary to listen to recommendations of experts. If there is a possibility, for removal of a moisture from топливопроводов at each refuelling fill in in a tank a special preparation; through everyone
10 000-15 000 km of run do full washing of system of injection.
