Assignment
The purpose of the fuel-mixture formation, is that, particularly in the petrol engine, the fuel should be mixed with the intake-air in certain proportions and is burnt
with the best
possible energy output and environmental compatability.
Function
In the vacuum intake petrol injection and the side combustion chamber method (Diesel engine), the fuel is
injected as a fine spray, into the intake-air. In the case of the direct injection, the fuel is sprayed through a nozzle, directly into the combustion chamber, this
method is
found in all Diesel- and direct petrol injection engines. This is why it's called 'internal mixture formation', as opposed to the 'external mixture formation' in
vacuum intake
injection engines. 06/10
