LPG cars in winter - high humidity

In winter, our cars are exposed to many adverse conditions occurring at the same time. One of them is increased air humidity.

It affects the electrical system of a car, especially if wire insulation is damaged. In the case of cars with gas installation, we should pay particular attention to…

… ignition system

Timely replacement of spark plugs and wires keeps the high voltage system in proper condition, so the engine can run smoothly in all conditions, even in winter.

Preventive (and consistent with car manufacturer’s requirements) replacement of ignition system components eliminates the possibility of damage during operation. It’s very important in engines fueled by LPG, as any (even a minor one) inefficiency of the high voltage system – unnoticeable when driving on petrol – will manifest itself clearly when we use LPG.

LPG system’s electrical installation

Solenoid valves (on LPG tank, in the regulator and in gas solenoid valve) and LPG injectors (which are, de facto, more precise solenoid valves) used in gas installations are held open by voltage from the electrical system. Therefore, the condition of all connections in the electrical system of the LPG installation is crucial, especially in winter, when weather conditions may contribute to the deterioration of contact.

It is also important to pay more attention to the wires that conduct voltage to connections (possible insulation damage or kinks). Trouble in providing voltage to the solenoid coils may cause them not to open, which will result in inability to switch the engine to LPG supply.

Wiring harnesses in gas installations are designed to minimize the impact of weather conditions on their operation. Hermetic connectors are used more and more often.

Increased humidity and severe salinity – due to road salt – also affect…

While installing LPG system, its elements are mounted also to the body. This involves making a number of holes, also to ensure correct ventilation of the area with tank fittings.

Before winter, it’s important to check the condition of anti-corrosion coatings that protect these holes. By filling up losses, we can eliminate potential corrosion centers. It’s especially important in winter when large amounts of salt and brine are used to keep roads passable.

When checking a car on a lift, it’s also worth inspecting the fastening of LPG tank and gas pipes. In winter, when the chassis has frequent contact with snow and slush, poorly attached pipes may simply be torn off.

These actions are carried out during technical survey of the gas system, therefore timely and regularly serviced LPG system will not surprise us negatively in the wintertime.
