Tto cycle engines used to power both two and four stroke motorcycles are fed with fuel (normal gasoline, special gasolines for some com- petition needs or, in some un- common cases, methyl and/or ethyl alcohol), which is suffi- ciently volatile and has ignition properties which allow it to be premixed with the combustion air before the combustion is ini- tiated by the spark plug. On the other hand, in Diesel cycle engi- nes, the fuel is less volatile and has ignition properties which require that it be mixed with air only inside the combustion chamber, where the pressure and temperature conditions are such to induce natural ignition.

For this reason, the power delivery of diesel engines may be adjusted by fuel delivery alo- ne, without the need to control the airflow. In Otto cycle engines, when the fuel is pre-mixed with the air, it is necessary to control the air- flow and therefore, indirectly, the fuel flow. In automobile en- gines, fuel injection systems are used in most models, controlled by a central unit that adjusts the duration of time during which the injectors remain open to deliver fuel into the air stream. As everyone knows, ana- logous systems have been adop- ted on some high range mo- torcycle engines. In most cases, however, carburetors are widely used, where the fuel is introdu- ced according to the vacuum ge- nerated on various systems of fuel jets. The carburetor is th e- refore designed to perform three. On the right, the main components of a Dell'Orto motorcycle carburetor are shown: 1.

This is a diagram of the gasoline delivery in the inducted airflow: the fuel inside the float cham- ber rises in the atomizer (31), going through the jet (32) which adjusts the delivery together with the needle (28); the liquid is emulsified first with the air arriving from the channel (13) insi- de the nozzle (30) then going into the venturi (29) it mixes with the air coming from the in- take (1).
