What is Fuel?
Your fuel, be it petrol or diesel, is a liquid which unfolds its effect in the engine: it releases energy. This can be boosted by optimising the combustion, thereby extracting more power from the fuel.
Fuel is created from a mixture of several hundred substances, hydrocarbons, extracted from crude oil refinement. These hydrocarbons are obtained by separating and chemically converting crude oil.
Fuel can have different compositions and has to comply with the statutory provisions.The European norm EN 590 defines requirements and test procedures for diesel fuels, how they are to be commercialised and delivered. These specifications guarantee satisfactory operation of Otto engines (petrol) or diesel engines. There are 4 different types of fuel: petrol, diesel, heating oil and LPG.
In addition to its physical and chemical properties, fuel has to have certain characteristics after refinement to ensure smooth running of the engine.
Generally speaking, fuel is a combustible substance. The energy derived from the combustion of the fuel is converted into propulsion. This is why fuel such as petrol and diesel is used as propellant for vehicles, aeroplanes and rockets. There are solid, gaseous and liquid forms of fuel, which include petrol and diesel.
