Regardless of the type of fuel which the wehicle is supplied with, it must be properly prepared for the winter season. Autogas-powered cars should go through a general overview of the installation and adjustment before the winter. The adjustment might be needed due to a change in the air oxygen content at low temperatures and because the autogas composition is being changed for the winter time - the proportion of propane is increased and butane is reduced.
Take care of the clean filters
Filters lose their capacity after stopping the air which adversely affects the proportions of the fuel-air mixture. In the autogas-powered units one should take special care about cleanliness and throughput of the filter. LPG system is equipped with filters of the liquid and volatile phase. During exploitation, they gather solid and liquid substances, which can block the flow of gas at very low temperatures and unable the work of LPG system. Regular replacement of filters allows to prevent such situations. If the filters are heavily contaminated, they should be replaced even before the periodic service.
Check the cooling system
The task of the coolant in cars burning propane-butane is also heating the regulator, which causes expansion of gas by changing the state from liquid to gas. You should therefore start by checking the tightness of the system. If there is a trapped air in a system, the unheated reducer freezes as the effect of expanding gas. If the radiator lacks in fluid, the regulator will also not work efficiently. It is therefore advisable to check the level and quality of the liquid and, if necessary, have it refilled or replaced.
Check the ignition system
The gas-air mixture is more difficult to ignite than the mixture of fuel and air. With a weak spark the engine will run unevenly, it can also result in so-called misfire. High voltage wires have limited lifespan. In the course of time they can get punctured. In the autumn-winter period, the engine elements are getting moistured which can lead to the high voltage break (approximately 20,000 V). The spark which should be ignited on a spark plug, arises between the wire and metal parts of the engine. Damaged power lines cause troubles with starting the engine and its uneven work. The high voltage wires should be replaced by the new ones according to the manufacturer advice, usually at 80 000- 100 000 km. We can estimate the condition of wires ourselves. One should raise the bonnet with the engine running just after dark. Thus, we can check how the sparks are ignited on wires. These wires must always be replaced.
Fill up your car :-)
Gasoline is also important. The driver of the car running on gas cannot forget about filling the tank with petrol. Firstly, always start the engine by energizing it with petrol and secondly, if there is too little gasoline in a tank, the water condenses in a container and blocks the fuel system when freezing. To avoid this you should fill the tank at least half full. In winter, it is also advisable to add to gasoline a special preparation absorbing water.
