Frequently Asked Questions

All gasoline-powered, carburetor, injection and injection with catalytic converter cars can be convert to gas.

Yes the system can be installed on all diesel engines, including generators. DDF (Diesel Dual Fuel) system can be fitted on cars, vans, pick-ups, buses, trucks and tractors. The mix/blend (Diesel with Gas) depends on the type of the engine, power and the engine's condition/age. Generally, 25% to 40% of diesel is substituted by the respective used gas in according to the applied conversion. This substitution results in substantial cost savings to the user with a more efficient engine. The DDF, when it burns in the chamber, not only lessens NOX, CO and CO2, it drastically reduces the carbon particulates (unburnt diesel smoke with suspended carbon particles) in the exhaust emissions thereby making it an ideal, eco-friendly choice for diesel-fuelled engines. Additionally, the DDF increases engine torque and power, prolongs engine life and leads to smoother running of the engine, reduced crankcase deposits and lesser oil changes

LPG is an energy-rich fuel source with a higher calorific value per unit than other commonly used fuels, including coal, natural gas, diesel, petrol, fuel oils, and biomass-derived alcohols. LPG generates fewer carbon emissions than gasoline (petrol) and diesel. Therefore it can make a positive contribution to air quality improvement compared to diesel, heating oil and solid fuels.

LPG is one of the cleanest conventional fuels available. It is non-toxic and has no impact on soil, water and underground aquifers. It also helps to improve the quality of indoor and outdoor air, as it produces substantially less particulate matter and NOX than diesel, oil, wood or coal. From a global warming perspective, LPG fuel can play a significant role in reducing emissions of carbon dioxide and other greenhouse gases. For many applications, including transport, cooking, heating, industrial processes and local power generation there is a major role in small and medium scale applications for alternative low carbon fuels, such as LPG, which have a smaller carbon footprint than traditional fuels. Studies consistently demonstrate that LPG generates fewer carbon emissions than gasoline (petrol) and diesel. In addition, the carbon footprint of LPG is more than 20% lower than gasoline and more than 10% lower than diesel.LPG therefore helps to reduce CO2 emissions. LPG also helps to reduce Black Carbon (BC) emissions, which are the second biggest contributor of global warming and which can cause serious health problems.

To ensure a good functioning through time the system is subject to periodic checks (ex. Replacement filter) according to a scheduled plan of maintenance each 15-20.000 km. These operations are generally made by the repair shop in the same time withcar's scheduled control with particular attention to ignition and electronics.

Normally a car powered by gas with one liter of LPG travels 5% less than one gasoline liter If the route with gasoline is 10 km/lt with gas will be about 9.5 km/lt while the power loss is about 3%-5% so not noticeable by the user.

The autonomy LPG car depends on the dimensions of tank installed, whose choice could be made in relation to the use of the car to privilege the load capacity or onmore autonomy of the car itself. In case it desire privilege the load capacity it's advisable to install atoroidal tank that is placed on the car's spare wheel compartment and keeps unchanged the load capacity. If the route with gasoline is 10 km/lt with gas will be about 9.5 km/lt. The tanks can be of different shapes and sizes so different autonomies. To have aindicative reference, with a 40 liter tank (32 lt effective LPG following the intervention of the safety valve) our car would have an autonomy about 290 km, instead with a 60 liter tank where it is possible insert 48 lt effective of LPG the autonomy will be about 480 km.

LPG can be used in any gasoline or diesel engine. LPG makes ideal fuels for combustion engines due to their high octane rating, low levels of volatile organic compounds and the fact that they can readily mix with air prior to combustion. These characteristics result in a more complete combustion, which helps to reduced exhaust emissions. The gas' clean burning characteristics also reduce engine stress, therefore extending engine life. Studies, over LPG usage, conducted for manyyears,they have shown that LPG does not shorten the engine life; on the contrary, it isestablished that engines running on LPG last longer. It is caused by chemical components of this fuel, which is seen during combustion (less pollution). LPG does not lower oil density; onthe contrary, it increases its viscosity, which reduces wear of the engine (pistons, rings,cylinder head's walls, etc.) Generally, LPG burns more completely and does not cause carbondeposit.

Yes they are safe! I The standards governing the construction of the various LPG components are very strict. Products that are installed in cars have been designed and manufactured taking into account the chemical and physical characteristics of LPG. LPG tanks are made from 3.5 mm steel plate that has been heat-treated to prevent cracking in the event of deformation (caused by an accident, for example). During the homologation process, the LPG tanks are subjected to a hydraulic pressure test and must not show any structural failure up to a pressure of 67.5 bar. Suffice it to say that the pressure developed by the LPG inside the tank normally ranges from 3 to 7 bars. In contrast, the petrol tank is made of plastic and melts at 160°-170°C and softens at 120°C. Finally, LPG pipes are made of metal, while petrol pipes are made of plastic or rubber.

The safety measures of the LPG system include a solenoid valve, positioned at the inlet of the pressure reducer, which prevents the flow of gas when the engine is switched off, as well as the safety devices of the LPG tank multivalve (solenoid valve, device for automatically shutting off the filling flow at 80% of the total capacity, safety valve) provided for by current ECE/ONU R 67/01 regulations, which guarantee maximum safety in all situations by preventing an excessive increase in pressure inside the tank due to external causes (fire, accident, parking in underground garages, exposure to excessive heat from radiation...) thus ensuring that safety standards are maintained. ...) thus ensuring that safety standards are maintained.

All gasoline vehicles: carburetor, injection All petrol, carburettor, injection and multi-point injection cars can be converted to CNG. CNG systems are also available for direct injection vehicles.

Yes, installation is possible for vehicles with a diesel engine. The system can be installed on all diesel engines, including generators. The DDF (Diesel Dual Fuel) system can be fitted to cars, vans, pick-ups, buses, trucks and tractors. The DDF (Diesel Dual Fuel) mixture varies according to various parameters: the type and configuration of the engine, its power output and, of course, the age of the engine. Generally, between 50% and 50% of the diesel can be replaced by CNG. With efficient, new-generation engines, this leads to considerable cost savings for the user. This conversion not only reduces running costs but also lowers NOX, CO and CO2 emissions, drastically reducing unburnt carbon particles in the exhaust, making it an ideal 'eco-friendly' choice. Finally, DDF increases engine power and torque, prolonging engine life and enabling smoother engine operation by reducing deposits of impurities in the crankcase and consequent oil changes.

First of all, we can say that the least expensive energy is methane, while the most expensive energy is petrol. The efficiency of the various types of fuel is as follows: - "Otto cycle" engines (spark ignition) have about 20% lower efficiency (also due to the presence of the throttle, which gives rise to significant leakage losses). - Between methane, LPG and petrol, which are used in Otto cycle engines, methane has a few more efficiency points thanks to its higher anti-knock power. Methane has an octane rating of 130 and has a slight efficiency advantage over petrol. - Natural gas is economical. - Methane is the cleanest operating fuel system burning today. This means less vehicle maintenance and longer engine life. - CNG vehicles produce the fewest emissions of any fuel. - Methane produces much less pollution than petrol. - Petrol-engined vehicles release carbon dioxide into the air through combustion, which contributes to global warming. This is greatly reduced with methane.

Methane is definitely more eco-friendly fuel among those commonly in use. A clean fuel but above all a ready and reliable, that is, unlike gasoline and diesel is not attained through complicated and expensive refining processes, which will inevitably be passed on to the sales price to the public, but from the beginning is ready to be used as an ecological fuel. In methane are almost totally absent impurities, such as sulfur compounds, and are absent poisonous compounds such as lead and polycyclic aromatic hydrocarbons and its combustion does not cause significant formation of odor or particulate matter. With appropriate technology and calibrations, the motors get very low emission levels. Detectable exhaust hydrocarbons are composed almost entirely of methane, non-toxic and already excluded in the calculation of emissions from existing U.S. law and EU legislation on heavy vehicles. The favorable ratio hydrogen / carbon of methane results in a production of CO2 considerably lower compared to other fuels. In particular, the reduction is about 20% in comparison with gasoline.

To ensure that the system works properly over time, it is subject to periodic checks (e.g. filter replacement) according to a scheduled maintenance plan every 15-20,000 km. These operations are therefore generally carried out by the workshop in conjunction with the regular servicing of the vehicle with particular attention to the ignition and electrical system.

1 cubic meter of methane corresponds to 0.671 Kg while 1 kg of methane corresponds to 1.49 cubic meters of methane (at 15 ° C and 1 bar pressure).

Running on natural gas results in the following changes: a loss of maximum power of only 10% on maximum torque, which translates into a drop in top speed of only 5%-10%. The fuel cost savings are due on the one hand to the different energy yields of the fuels and on the other hand to the government's tax policy. In terms of energy yield, 1 kilogram of methane corresponds to approx: - 1.675 litres of petrol - 1,300 litres of diesel - 2,000 litres of LPG

To calculate the autonomy of a car fuelled by CNG, it is necessary to know that 1 kg of CNG corresponds about 1.7 litres of petrol and that the coefficient of distance of CNG/petrol is 0.3 (therefore with a 70 litre CNG cylinder the distance covered is comparable to that covered with about 21 litres of petrol). An example: let's suppose to have a 70 lt CNG cylinder; it allows therefore a distance comparable to about 21 lt of petrol (70 lt x 0,3); let's suppose that the car runs with petrol 10 km with a litre; to calculate the distance, we will have to use the following formula: 70 lt x 0.3 x 10 = (21 x 10) = 210 km of autonomy on natural gas.

CNG for automotive use has interesting physical and thermodynamic characteristics, in terms of quality and cleanliness of combustion and safety of use. The gaseous state of methane and its high speed of diffusion in the air make it easy to obtain excellent carburation even in the initial phases of operation with a cold engine. This circumstance, together with the fact that, compared to petrol engines, methane emissions upstream of the catalytic converter are considerably lower, accentuates the benefits of using natural gas vehicles in city centres, where cold starts, short journeys and slow running in columns are particularly frequent; conditions which do not allow the engine and catalytic converter to reach ideal operating temperatures quickly.

The use of CNG offers ample guarantees of safety, in many respects greater than traditional fuels. CNG has a lower density than air, so if it escapes into the environment, it tends to disperse upwards without forming dangerous concentrations or accumulations on the ground. To test the safety of CNG systems, dozens of crashes and fire tests have been carried out to verify, with the most sophisticated equipment, the efficiency and safety level of systems and tanks. CNG has the highest flash point of all other fuels. Its auto-ignition temperature is, in fact, double (650° C) compared to liquid fuels, and the concentration of fuel in the air for combustion to occur (5%) is much higher than petrol (1%) and diesel (0.5%). These are factors that contribute to significantly lowering the risk of an accident with fire development. Finally, CNG is not dangerous to health, even in high concentrations, as it is not poisonous.
