D-GID Dual-Fuel Road Test Cuts Fuel Costs by 18.8%

D-GID双燃料系统通过测试表明燃料成本削减18.8%

March 18, 2015 | Italy, Serralunga di Crea (AL)

Ecomotive Solutions, a company of the Holdim Group, recently presented the results of a road test of its d-gid dual-fuel electronic platform applied to an Iveco Stralis 450 Euro 5, fuelled with methane (both gaseous and liquid) and diesel. The tests, conducted as part of a project sponsored by the Brescia Industrial Association, the CSEAB consortium and the FAI of Brescia, with the participation of the University of Brescia and ENEA, had the objective of demonstrating the effectiveness of dual-fuel technology under real operating conditions.

Ecomotive solutions是一家属于瑞士豪瑞集团的公司，最近他们进行了一项测试，应用在Iveco Stralis450卡车的d-gid双燃料电控平台，此卡车是欧五标准，燃料使用甲烷（气态以及液态）和柴油。此项目由其项目赞助商布雷西亚工业协会，CSEAB财团以及布雷西亚投资集团来管理，并且布雷西亚和ENEA大学参与。此项目旨在验证在真实工作工况下，双燃料技术的节能效果。

The road test, conducted on the vehicle made available by Bresciana Ghidini Rok, after 12,500 Km (75% on motorways and 25% on trunk and mountain roads) recorded:

在路试阶段，由Bresciana Ghidini Rok进行实验，在经过12，500公里（75%在高速公路，25%在土路和山路）的记录如下：

§ an average saving in diesel of over 44%, corresponding to a reduction of approx. 18.8%* in fuel costs;

§ 平均柴油省44%,与大概18.8%的燃料成本节省一致。

§ no change in torque and power of the dual-fuel vehicle compared with diesel only;

§ 在功率和扭矩方面与纯柴油汽车方面并无变化。

§ use of natural gas/biomethane and a lean mixture of diesel significantly reduces CO2 and Particulate (PM) engine emissions;

§ 使用天然气/甲烷以及稀柴油混合，可以显著的降低发动机的CO2和污染颗粒排放。

§ engine noise is reduced by up to 5 dB thanks to the combustion of natural gas; and

the oil quality does not deteriorate with the same progression as the original vehicle, due to the effect of an average decrease of 50% in the diesel soot deposits at constant operating temperature and pressure.

§ 发动机由于使用了天然气，噪音降低了5分贝。并且比对原来的发动机，在同样工作过程中，机油品质也不再恶化。由于柴油的碳烟以及工作温度和压力降低了50%。

Participation in the project of the University of Brescia allowed the risk analysis of a liquefied natural gas (LNG)/diesel dual-fuel system to be carried out, demonstrating its intrinsic safety, while ENEA carried out research on the use of the methane-diesel mixture for professional road transport, aimed at demonstrating the environmental benefit of this retrofit solution, if applied on a large scale at the national level.

布雷西亚大学参与在这个项目中，允许液态LNG/柴油双燃料的误差分析，证明其本质是安全的。同时ENEA也得出了使用甲烷以及柴油的混合器的专业路试实验结论，目的在于证明如果在大范围比如国家级水平应用时，其对于环境保护的益处。

It should be noted that the d-gid (diesel -gas dynamic injection) dual-fuel platform developed by Ecomotive Solutions is capable of fuelling a diesel engine simultaneously with a mixture of gas (CNG, LNG, LPG, biomethane, syngas, hydromethane, etc.) and diesel. Application of the d-gid system does not in any way change the nature of the diesel engine, maintaining the initial performance and efficiency; moreover, in the absence of availability of gas, the system automatically returns to operate with 100% diesel.

In Italy there is a network of installers certified by Ecomotive Solutions for the conversion of heavy vehicles with the d-gid dual-fuel system.

通过此图可以看出，由Ecomotive Solutions公司开发的d-gid（柴油-气动态喷射）双燃料平台可以同时供应发动机以混合气，包含CNG、LNG、LPG、沼气、一氧化碳混合气等。

并且使用d-gid系统并不会在任何程度上改变柴油机本质，仍会保持原来的初始性能以及功率。更进一步，如果供气停止，则系统会自动切换到100%的柴油状态。

The d-gid dual fuel system is approved by the Italian Ministry of Transport for use on heavy vehicles up to the Euro 5 category, while the application for Euro 6 engines is already under development in the Ecomotive Solutions laboratories.

d-gid双燃料系统由意大利的运输部门验证，使用在重载车上，可以达到欧五标准。并且欧6标准已经在Ecomoitive公司的实验室进行开发了。
