Importance of fuel preparation
Fuel is needed in the car to power the engine. This happens through the reaction of the fuel-air mixture. The atoms of the fuel oxidize and produce heat, CO2 and water. This sets the cylinder piston in motion and the energy generated is converted into motion. The rotary motion drives the wheels and the generator or other aggregates. In the vehicle, the entire combustion process is carried out through the tank, a distributor pipe, the fuel pump, the fuel filters, injection valves, air flow meters, lambda sensors, gaskets and, in old cars, the carburettor. If your car cannot be accelerated or you hear strange noises while driving, have your car checked. This is probably due to a problem in the fuel preparation.

Perfect mixing ratio through pumps, intake valves & lambda sensors
The aim is to burn the mixture completely, for this purpose the composition must be perfectly mixed or, over time, spread well in the combustion chamber. That is why we differentiate between two mixture formations: The inside and the outside. In the case of internal mixing, the injection process takes place directly into the combustion chamber. The pressure allows the fuel to mix with the intake air. The power is regulated by the quantity, thus the quality of the mixture changes. In external mixing, the mixture passes before the combustion chamber in the intake manifold, with time the substances mix before the intake valve and before the injection process. Here the output is regulated by the quality and not the quantity of the fuel mixture. For this the throttle cap is necessary to regulate the outflow. This is also needed for older cars, whose injection process is controlled by the carburetor. Here the intake air of the cylinder is used. The mixture reaches the cylinders through the throttle caps. Before that, an air stream travels fuel residues from the outlet pipe and forms an aerosol. If there is excess fuel, the mixture is called a rich mixture, if there is too much air, the mixture is called a lean mixture. The perfect combustion air ratio is called lambda. This describes the ratio of fuel and air that enables complete combustion. A lambda sensor in your vehicle measures this ratio and the pollutants produced. These can then be partially neutralised by the catalytic converter.

Fuel preparation means the formation of a fuel-air mixture that drives the engine. The system consists of various components that control the amount and composition of the substances and produce the mixture. Every engine needs a different quality and quantity of fuel composition, that is what the necessary parts are for. The process and its control is electronic. The driver can aim for different goals, such as increased engine performance or lower consumption and better exhaust emission values. Also important is the method of injecting the fuel into the engine, which is different for petrol and diesel engines. It is important to pay attention to the pressure, as this guarantees a perfect mixing ratio and thus leads to a more efficient combustion in the engine.
