New generation of engines of reduced environmental impact adapted to work with non-conventional fuels and lubricants.

To adapt engines and their internal components, such as combustion engines, for use with non-conventional fuels and lubricants, minimising noise and gas emissions caused by engines and improving the lifetime of components.

Engine components have been designed to withstand the properties of diesel and petrol engines. The use of non-conventional fuels and lubricants made it necessary to adapt the characteristics of the materials/coatings of the main components. The main objective of the EQUIMOTOR PLUS project is to adapt engine components and to find the best coatings for these components that may reduce corrosion, friction, wear and weight with engines working with alternative fuels and lubricants. In the project consortium, the following countries are included: SPAIN, FINLAND, CZECH REPUBLIC and UNITED KINGDOM. The European participants cover different areas such as engine manufacturers, lubricants and industrial liquids production and R&D centres. The activities required to achieve the overall objective are the following: - Redesign of engine components to be able to adapt to non-conventional fuels and lubricants (biofuels, fuels with a high content of sulphur and low viscosity lubricants). - Development of the coatings and surface properties (PEO, PVD (Physical Vapour Density), HVOF (High Velocity Oxy Fuel), plasma spray, surface texturing, etc.) to improve resistance to the wear and corrosion of the engine components. - Development of lubricants (to make them compatible with biofuels and fuels with a high sulphur content). - Advanced characterisation (simulation of wear, corrosion, fretting, residual stress, vibration, noise in the laboratory) and tests in engines and compressors for validation of new solutions. The work to be performed has been divided into the following tasks: Task 1 - Structural, thermal and FEM (Finite Element Method) calculus for the improvement of the design of the engine components. This first task is focused on reducing the emission in a two-stroke engine by means of the use of light materials in the engine jacket. Task 2 - Injection system study. Adaptation of the injection system to the use of non conventional fuels. Task 3 - Simulation and control of fretting, abrasion and adhesion. To minimise the effects and propagation of the vibrations in the engine elements. Task 4 - New coatings and surface texturing for engine components to reduce friction. This activity is aimed at the protection of engine components against knocking and wear. Moreover, the coating texturisation effect in the tribological behaviour of the engine components will be checked. Task 5 - Adaptation of the design of the engine components to reduce emissions. Piston engine redesign, reducing noise and vibrations. Task 6 - Development of non-conventional lubricants. This includes: - Low emission, low consumption and biodegradable lubricants. - Lubricants with high resistance to corrosion for engines working with biodiesel. - Lubricants for engines working with high sulphur content non-conventional fuels. Task 7 - Advanced tribological simulation (hidrofobicity, residual stress, hidrophylicity of critical elements). This task includes advanced simulation of bearing material and camshaft material. Task 8 - Improvement of behaviour against corrosion and tribocorrosion of critical components (valves, piston rings, pumps). In this task, these activities will include the identification and reduction of the corrosion mechanisms of the critical components and synergies between corrosion and wear. The corrosion mechanisms of the critical components will be reproduced at laboratory-scale. Task 9 - Tests in engines and compressors to select the best components. Finally, the performance of the new materials and coating and the emissions of the non-conventional fuel and lubricants will be evaluated. The results of this project are strategic for the consortium, with several sectors involved: energy generation, maritime, agricultural machinery, automobile, chemical and environmental.
