S.�GB1For the first time in the history of the Škoda vehicles, the customer is offered a liquefied petroleum gas powered vehicle directly from the factory. Liquefied petroleum gas is also known as liquid gas or LPG (Liquefied Petroleum Gas). LPG has already been used for decades and is currently the world's most widely used alternative fuel. It is a clean-burning fuel, therefore making it one of the most modern energy carriers. In many big cities more and more vehicles run on LPG, which is largely due to the rising popularity of this fuel.Protected by copyright.

S.�LPG consists of a mixture of propane, butane and additives. Compared to other fuels, the use of LPG results in significantly lower exhaust emissions. Overall, the emissions produced by liquefied LPG vehicles are among the lowest emissions achieved at present by internal combustion engines. The LPG fuel is virtually sulphur-free and the combustion takes place with almost no soot emissions. Pollutants such as carbon monoxide (CO), hydrocarbon (HC), nitrogen oxides (NOx) and other exhaust gas components, which pose adverse health and environmental risks, are significantly reduced.2GBContentsBrief presentation of the LPG system 4System components System overview834Safety concept36Engine management42Wiring diagram44Protected by copyright.

Flex Fuel (E85) engine with the identification characters CCSA, which in turn is based on the technology of the 1.6 ltr. 75kW MPI engine with the identification characters BSE and is known from the Škoda Octavia II model range. There are no mechanical adaptations of the petrol engine CCSA necessary to enable LPG operation. The normal petrol operation remains unchanged and a switchover to LPG operation is possible using the conversion button in the centre console. In gas operation, the engine produces a power output of 72kW.Technical highlights 2-valve technology with roller rocker arm aluminium engine block with ribbed oil pan secondary air system plastic variable intake manifold modifi ed applications of the engine control unit, Protected by copyright.

The valve for the gas tank regulates the LPG flow from the gas tank to the evaporator in the engine compartment. The opening and closing functions of the valve are actuated by the gas control unit. When switching over to petrol operation or switching off the engine, in the event of a high severity accident (crash detection) or a loss of voltage supply, the valve closes automatically.SP73_38Function Valve closed Valve openedSpring Coil Armature Valve to the evaporatorSpring Coil Armature Valve to the evaporatorSP73_53SP73_54from the gas tankfrom the gas tankIn the de-energised condition, the valve armature is pushed into the valve seat by the spring force and thereby shuts off the gas inflow from the gas tank to the evaporator.If all the system requirements for the gas operation are fulfilled, the gas control unit energises the electromagnetic valve for the gas tank N495.

This thrust movement is converted to the rotational movement by means of a lever system in the gearbox unit when the filling level changes. The annular magnet located at the end of the shaft, which protrudes from the gearbox unit, rotates as a result of this. The shaft end with the annular magnet is integrated in a housing within the valve body. Another magnet can also be found in the display unit. Depending on the filling level, the two annular magnets have a certain position to each other. The two magnets are separated by an insulation gap within the valve body and thus form a contactless magnetic connection. This magnetic connection influences the position of the needle in the display unit, where the filling level of the gas tank can be read off. This movement transfer between the float and the needle, which is created by the magnetic field, does not exclude the risk of gas escape. The display of the filling level on the body of the multi-function valve only serves as a safety feature.18GBContactless magnetic connectionHousing in the body of the multifunction valveDisplay unitMagnet of the display unit Annular magnet on the shaftSP73_55Gas supply indicator G706 in the centre console∞Ω0ΩSP73_49Sender for gas supply indicator G707Gas control unit J659Gas supply indicator G706Function The driver is informed about the filling level by means of the gas supply indicator G706 integrated in the conversion button, which is located in the centre console in the passenger compartment.

In addition, the evaporator has the task to reduce the pressure of the LPG from approx. 10bar to 1bar above the pressure prevailing in the intake manifold. The pressure of the LPG is reduced in two stages in the evaporator. The pressure fluctuations can be better compensated for because of the twostage pressure reduction.SP73_14Technical highlights1st stageunless authorised by ŠKODA AUTO A. S. ŠKODA AUTO A.

The LPG flows between the 1st stage and the 2nd stage via an over flow channel which connects both stages. In addition, each stage has a valve with a flap and a piston. The piston is screwed to the diaphragm. Each side of the evaporator has a spring chamber. A spring is located in each spring chamber. Atmospheric pressure prevails in the spring chamber of the 1st stage and intake manifold pressure prevails in the spring chamber of the 2nd Stage. Between the 1st and 2nd stage is a rubber seal that separates the cooling circuit from the LPG.1st stage Inflow from the high-pressure valve for gas operation N372 Diaphragm Flap Inner chamber Piston Spring2nd stage Over flow channel Outlet to the gas filter Diaphragm Inner chamber Flap Piston SpringSpring chamber Spring chamberProtected by copyright.

At the same time the gas and its surroundings cool down creating the so-called "cold expansion" effect, which could lead to the evaporator icing up. Therefore, the cooling circuit of the evaporator is connected to the cooling circuit of the engine before it is connected to the heat exchanger. In this way, the heated cooling water contained in the evaporator prevents ice formation.24GBThe electromagnetic high-pressure valve for gas operation N372The electromagnetic high-pressure valve for gas operation N372 is mounted on the evaporator housing and serves to interrupt the gas supply from the gas tank to the evaporator. A filter is integrated in the high-pressure valve. It is used to filter out the impurities in the liquid LPG in order to protect the sensitive component parts of the evaporator.

This means that the injection valves are actuated by the gas control unit and are briefly raised shortly before switching over from petrol to LPG mode. This is a safety measure against residues penetrating into the gas injection valve and it also prevents bonding.28GBFunction During the LPG operation, the gas injection valves blow the LPG which is in the gaseous state into the intake manifold of each cylinder.Not actuatedSpringPistonMagnetic coil Upper chamber Armature Gas inletThe gas injection valve is de-energized. The pressure spring pushes the piston with the armature and the sealing lip downwards and thus closes the gas outlet to the intake manifold. LPG flows through the gas inlet into the lower chamber and passes through the bores in the armature into the upper chamber of the gas injection valve. Through this, the same gas pressure acts on the armature in the upper and lower chamber. The pressure prevailing in the lower chamber prevents the armature with the sealing lip being pushed up counter to the spring force and the gas injection valve from opening the gas outlet.Lower chamber Gas outletSealing lipSP73_34ActuatedSpringPistonGas inletThe gas injection valves are actuated by the gas control unit using the PWM signal. The electrical connection and the magnetic coil are located in the valve housing. When the magnetic coil is energised, this generates a magnetic field. In the magnetic field the armature together with the Magnetic sealing lip are raised counter to the spring force coil of the pressure spring and the gas outlet opens. Protected by copyright.

It serves to measure the pressure and the temperature of the LPG. The gas temperature and the gas pressure are used to calculate and control the opening times of the gas injection valves. The gas pressure signal also determines when it is required to switch back to petrol operation: - inadequate LPG in the gas tank - a pressure drop in the gas system - clogged gas filterSP73_36Protected by copyright.

A temporary malfunction During a brief period of full-throttle acceleration (for example when overtaking) the gas pressure is no longer adequate if the filling level in the gas tank is low. If the conditions for the gas operation are met during a "temporary malfunction" (in our example: the engine runs in the partial load range or the gas tank was refilled), the system switches over again to gas mode after operating the conversion button.2. A fault in the LPG system (e.g. if a disconnection of the gas injection valve is detected) If a "fault in the LPG system" is present, in our example if a disconnection of the gas injection valve is detected, it is not possible to switch over to LPG operation. Both categories of faults are detected by the system and an entry is made in the fault memory of the gas control unit J659. Thereby, the orange LED "OFF" lights up and the blue LED "ON" flashes quickly. In addition, a quick intermittent beep sound is heard. The system automatically switches over to petrol.

The high standard of safety has been confirmed by a series of crash tests.Safety components of the LPG system:The gas fuel tank filler neck with the non-return valve The non-return valve prevents the gas flowing back after refueling.SP73_05The LPG tank The LPG gas tank is located in the spare wheel well and is therefore protected as best as possible against mechanical damage and weathering. It consists of 3.5 mm thick sheet steel, is heat resistant and meets the highest safety requirements. Each fuel tank is subjected six times to a safety test during the production and is provided with a serial number and a test certificate.SP73_43Protected by copyright.

S.�36GBTo support the high reliability of LPG vehicles, the LPG is mixed with odourants. This allows even the smallest leaks of the LPG system to be perceived by sense of smell.The cut-off valve The cut-off valve automatically shuts off the inflow of LPG when refuelling once the gas tank has reached a filling level of 80%. This ensures that there is enough room in the gas tank for expansion during an increase of temperature. The valve also prevents the gas from flowing back after refuelling.SP73_39The overpressure safety valve The overpressure safety valve prevents the rupture of the LPG tank from the build-up of excessive pressure in the tank, for example as a result of high temperatures. As soon as the pressure in the tank exceeds 27.5bar, the valve opens mechanically and remains open until the pressure in the tank has returned to normal.SP73_40GBProtected by copyright.

The original wiring from the engine control unit to the petrol injection valves is interrupted and is provided with an electrical plug. The petrol injection signals are transmitted from this plug to the gas control unit, where they are used for the calculation of the gas injection times. To avoid a fault message in the engine control unit, due to an interruption in the wiring, the engine control unit receives the expected signals of the petrol injection valves by means of resistors in the gas control unit.Gas control unit J659 Engine control unit J623Connection interruptedPlug connection in cable harnessSP73_47Injection valves N30-N33Gas injection valves N366-N369Legend Earth PositiveProtected by copyright.
