ACEA
Sign of the Asociación de Constructores Europeos de Automóviles (European Car Manufacturers Association)Admission
The phase during which the filling of the cylinder is produced. While the admission valve is open and the piston goes down, from the top dead centre (TDC) to the lower dead centre (LDC). The empty space which the piston leaves is transmitted through the inlet duct in order to collect air from the atmosphere and introduce it into the engine. In diesel engines admission is only produced with air.Admission valve
This is in charge of making way for the mixture in the inside of the cylinder opening or closing the ducts of the admission collectors. They are kept open in the admission cycle and are closed in the three remaining ones.Air inlet valves
Channelling found in the cylinder head in order to join the manifolds to the combustion chamber. They are carried out from the smelting of the cylinder head and its extremes are simply mechanized in the combustion chamber in order to place seats in the valves. Its design and superficial finish affect the filling of the cylinders.Anti-corrosion
Element or characteristics of an element which avoids the oxidation of a material by making the reaction of oxygen with the protected material difficult.Anti-foaming
Element or characteristic of an element used in order to avoid the formation of foam when a liquid is beaten or has air inlets.Antioxidant
Element or characteristics of an element which avoids the oxidation of a material by making the reaction of oxygen with the protected material difficult (See Anti-corrosion)Anti-rusting
Element or characteristic of an element used in order to avoid condensation and the accumulation of water on the surface of a material. It prevents rust from forming on the material.Aromatic content
This is said of unsaturated cyclical molecules, whose stability is greater than that of open-chain structures with an equal number of multiple links.
