In order to realize sustainable mobility in Europe, future vehicles for road transport will have to be significantly more efficient by 2020+, and a considerable contribution
to this target will have to come from the energy efficiency improvement of the powertrain.
On the other hand, a strong de-carbonisation process has been launched to drive the European transport sector to the 2050 target and the use of Low Carbon Alternative Fuels,
like Natural Gas, will play a fundamental role to accelerate this process.
In this context, GasOn project aims to develop advanced CNG only, mono-fuel engines able to comply with the “2020+” CO2 emission targets, claiming the
20% CO2 emission reduction with regard to current best in class CNG vehicle segment by segment, to fulfill the new homologation cycle and to guarantee
a low fuel consumption even in real driving conditions.
To reach these targets, starting from the lessons learnt by previous EU FP7 funded INGAS project (www.ingas-eu.org), GasOn project is based on
3 parallel technology ways that will lead to a full development of demonstrator engines, all based on the integration of the gaseous direct injection technology with others
like advanced Variable Valve Actuator VVA, advanced boosting, variable compression ratio, charge dilution combustion and related improved aftertreatment.
The synergic integration of technologies with CNG direct injection on top enhances boosting efficiency at low engine speed with benefits both in terms of performance and
CO2 emission reduction.
To complete the investigation of all potential exploitable technologies for CNG engines, an ignition chamber concept, with extended lean burn combustion and diesel like compression
ratio, will be developed, as well as gas quality sensor that will determine the fuel characteristics and will enable a predictive engine control parameters optimization.
The final outcomes will be 3 demonstrator vehicles (one for each technology way) equipped with advanced storage systems enabling driving range equivalent to conventional fuel
(without any drawback in terms of trunk capacity) and mitigating the weakness of refuelling infrastructure.
