Yes, they are safe. Products installed in vehicles in specialised workshops are approved by the Transport Ministry on the basis of European standards.
All Landi Renzo products are also tested one by one on the basis of our quality system, which obtained ISO 9001 Certification in 1996 and ISO TS 16949 Certification in 2001, the Quality System specific to the automotive sector involving the application of extremely strict quality standards.
Leakage of gas from an LPG system is much less likely than leakage of petrol. Fire tests have demonstrated that in the event of a fire, flame volume is much smaller than in the case of petrol leakage, which tends to spread over the ground around the vehicle.
Dozens of crash and fire tests have been conducted, in collaboration with fire fighters, using the most sophisticated equipment to check the efficiency and safety of valves and tanks.
LPG stands for Liquid Petroleum Gas. It is a by-product of the refining of crude oil. LPG is a gas at atmospheric pressure and normal ambient temperatures, but it can be liquefied when higher pressure is applied and/or when the temperature is reduced.
The LPG used in vehicles is a blend of propane and butane gases with chemical and physical properties that help vehicle performance in terms of power, versatility and engine functioning.
The products of its combustion are carbon and nitrogen oxides and unburnt hydrocarbons, in smaller quantities than produced by petrol and diesel-fuelled vehicles, while aromatic hydrocarbons, sulphur dioxide and particulates are absent.
The energy content of LPG is 10,000 kcal/kg, while that of petrol is 10,300 kcal/kg.
Yes, it’s true. The running costs for an LPG-powered vehicle are significantly lower than those for a petrol-fuelled one
An LPG fuelling system involves the use of two types of tank: cylindrical or doughnut shaped.
These two types of tanks are available with different capacity, diameter, weight, etc.
When a cylindrical tank is housed in the boot of the car, the load capacity reduces according to its size. Housing a doughnut shaped tank in the place of the spare tyre, instead, safeguards the space available.
The cylindrical tank is normally positioned in the boot; the doughnut shaped tank, instead, is normally housed in the place of the spare tyre. Both types can be positioned on the outside of the vehicle in compliance with safety distances.
When a cylindrical tank is housed in the boot of the car, the load capacity reduces according to the tank’s capacity. Housing a doughnut shaped tank in the place of the spare tyre, instead, safeguards the space available. The spare tyre can be stored in a special bag, or replaced by a tyre repair kit.
Yes, for sure. The Landi Renzo Gas workshops are properly trained to convert this kind of car and they are therefore able to make the most appropriate setting.
The weight of the LPG system is calculated as part of the total load that can be transported by the vehicle (people + luggage).
Therefore, the driver must take into account the weight of the system installed when determining the maximum load that can be transported.
No, LPG tanks do not need to be serviced. LPG tanks must be replaced after 10 years of use.
In this regard, it should be noted that the tenth year of use should be understood as commencing.
All petrol-fuelled cars, vehicles with carburettor, injection fuelled vehicles and injection fuelled vehicles with catalytic mufflers can be converted to run on gas, whether with an indirect or direct injection system.
When having an LPG or Natural Gas system installed on a vehicle, it is advisable to check with a specialised workshop as to which type of system should be installed on the specific vehicle model.
It is technically possible (if the engine characteristics are similar and allow it), but it is not economically viable as the cost savings resulting from not having to purchase new components are cancelled by the double cost of labour.
Installation of an LPG or CNG system normally takes just a few days in a specialised workshop.
Installation of an LPG or CNG system will not affect the vehicle’s ability to run on petrol.
The driver may decide which fuel to use by simply pressing a changeover button on the dashboard.
Today’s gas systems are easy to use as they ensure the vehicle always starts up running on petrol and automatically switches to gas after about 15 to 60 seconds, when optimal running parameters have been reached.
Installation of a gas system practically doubles the vehicle’s autonomy, which can now count on two fuel supplies.
LPG tanks have always been designed and constructed taking into account the chemical-physical characteristics of the fuel. LPG tanks are built using 3.5mm steel sheets, heat-treated to avoid cracking in case of deformation (caused for example by an accident).
The standards governing the construction of the various components are very severe. The tests and trials for tanks and pipes are performed at a pressure of 45 bar, although normally the operating pressure in vehicles never exceeds 20 bar.
No. The system, properly set, keeps the Start & Stop strategy active: The vehicle turns off and reactivates with gas, without problems. A preventive consultation with your Landi Renzo workshop is always useful, anyway
