Combustion of liquid hydrocarbons fuels in transport generates pollutant emissions, which have non-negligible effects on human health and on the earth's atmosphere.
The aim of this project is to answer the question how could we enable a reduction of fuel consumption and pollutant formation by acting on engine technology and fuel and lubricant formulations in order to increase the system efficiency. The main objective of this project is to help to define the best matching between fuels (including additives), lubricant and vehicles equipped with high depolluted and low consumption engines.
The work programme is divided into two subprogrammes: diesel engines and spark ignition engines, each of them split up into five phases:
Phase 1 will be dedicated to fuel definition and preparation, supplying of engines, vehicles and control systems. Chosen engine and anti-pollution technologies are those which might be predominant in the near future: 1. IDI diesel engine for passenger car with high rate of EGR and oxidation catalyst;
2. DI diesel engine for passenger car with high rate of EGR and oxidation catalyst;
3. DI heavy duty engine with oxidation catalyst or particulate trap; 4. SI engine running at stoichiometry with high rate of EGR and a three way catalyst;
5. SI lean burn engine with three way and De NOx catalysts.
In phase 2 tests will be performed on engines using the different fuels. Performances and emissions (including noise) will be measured for different running conditions (standard and after variation of EGR rate, injection and/or ignition timing...).
In phase 3 the regulated and non-regulated emissions of four different vehicles, equipped with engines equivalent to those previously tested, will be measured on the European driving cycle.
In phase 4 driveability tests will be performed on a SI and on a diesel vehicle.
In phase 5 tests will be realised on two engines (diesel and SI). For each of them, two different lubricant formulations and two fuels will be evaluated through a 100 h duration procedure.
Expected Achievements and Exploitation
The project should lead to a valuable enlargement of our knowledge on the sensibility of modern engines and on the behaviour of the post-treatment devices when the characteristics of the fuels change.
