The d-gid system is the first technological platform developed by Ecomotive Solutions. This revolutionary electronic management system is designed to power diesel engines with a dynamic controlled mix of diesel and gas (CNG or compressed natural gas, LNG or liquefied natural gas, LPG, Bio-methane, Syngas, etc.). The dynamic control of the primary diesel injection and the accurate metering of the air-gas mixture are the key strengths of the system, which is constantly controlled via a 'smart' control unit, which communicates with the engine in real time to ensure that it is functioning optimally, and in absolute safety. The system has no impact on the diesel engine on which it is fitted; installation is not invasive, and can be reversed if desired.

The only difference between the DIESEL DUAL FUEL system and traditional natural gas or LPG systems is the fact that it provides mixed and simultaneous power (diesel + natural gas or diesel + LPG).
The DIESEL FUEL DUAL electronic control unit calculates the correct dosage of each fuel required in real time, substituting some of the diesel fuel with an optimised percentage of natural gas or LPG. This results in superlative fuel combustion, with less pollution than the original system.

Yes, because the system has no impact on the diesel engine on which it is fitted. 

As is the case with LPG and natural gas systems for petrol engines, the DIESEL DUAL FUEL system is composed of a front part, positioned inside the engine compartment, and a rear section, which includes the tanks. The installed components are relatively similar to those used on cars, but the way in which the tanks are installed can vary depending on the type of vehicle in question. These can be placed in the rear of the vehicle (boot) in the case of cars, on the underbody of light commercial vehicles, or alternatively, the tanks can be positioned laterally, freeing up space where necessary on other types of vehicle (heavy vehicles, Eurocargo trucks, vehicles with an average load of 7500 - 15000 kg, and light commercial vehicles). On buses, the tanks can be fitted inside the baggage compartment.

The only example of vehicles with limited space is road-going tractors. In this instance, the diesel tank size is usually reduced, or the largest tank is simply removed, enabling the natural gas tanks to be fitted using type-approved brackets.

Yes, it is possible to remove and refit the system more or less without disassembling it on other vehicles with equivalent technology, before performing a system calibration on the new vehicle.

Ecomotive Solutions systems control the amount of diesel injected, and this is reduced by up to 80-90% (consistent engine load). The average substitution under dynamic conditions of use is 40-50%.
For optimal engine conversion, the DIESEL DUAL FUEL control unit that controls the engine needs to be specifically calibrated to it. This is why average diesel-natural gas substitution percentages vary in accordance with the type of vehicle in question. For cars and light commercial vehicles, a percentage of around 50-55% is realistic, while for heavy vehicles, the percentage is around 40-45%.

All diesel engines can potentially be converted into DIESEL DUAL FUEL engines; if your vehicle is not present in the list of applications on the website, you can either complete the online form or send us a copy of the vehicle registration booklet to

In light of the fact that this product is extremely innovative, it is advisable to entrust the initial stages to the experience of Ecomotive Solutions workshops which already specialise in the installation of such systems. However, it is in our interests to train the largest possible number of facilities across the national territory. To find your nearest workshop, send us an email at

The installation time depends on the structure of the vehicle. The installation of a system on a light commercial vehicle usually necessitates around three days of vehicle downtime, while for a heavy vehicle, this is increased to around five days.

The DIESEL FUEL DUAL system is added onto the original engine, with no mechanical modifications, and accordingly, the performance of a vehicle converted using an Ecomotive Solutions system is not affected - it remains unvaried. The goal of the DIESEL DUAL FUEL system is to maintain the energy balance with regard to combustion, efficiency and performance of the engine. 

No, a number of tests carried out in accordance with manufacturing standards have demonstrated that using diesel natural gas or diesel LPG systems has no adverse effect on engine life.

The fuel autonomy of the vehicle corresponds with the relationship between the amount of natural gas stored, the consumption/km on diesel only, and the average percentage of fuel substitution, which varies according to vehicle type.
The figures given for kilometres travelled relate to the point at which the CNG or LPG runs out, after which the vehicle automatically goes back to using diesel.

Installation of the DIESEL DUAL FUEL system increases the overall fuel autonomy of the vehicle, in that natural gas or LPG tanks are added to the vehicle. Furthermore, when using DIESEL DUAL FUEL, the amount of diesel fuel consumed is reduced compared to driving on diesel alone.

To maintain the efficiency of the DIESEL DUAL FUEL system, periodic maintenance must be carried out, in addition to regular servicing checks, including:

• replacement of air filter and checks on diesel injection system
• replacement of gas tanks, in accordance with type-approval regulations.
• replacement of gas filter, in accordance with the specifications provided in the use and maintenance booklet.

Users are advised to follow the instructions provided in the use and maintenance booklet provided with the system.
