A few pics I took Wednesday at Galleria Ferrari to visualize what we are talking about.
Here a global view of the 036 (1990), V12 3497 cc.
As you can see it has 3 fuel rails on the top, a central one and two, one per bank, on the outer sides. That’s because that engine had 2 injectors per cylinder, one under the throttle and the other one above it.
We can take a look in the intake so we can clearly see the two injectors :
Other things to notice, the 3 intake valves and the use of two sliding plates (how do you call that setup in English ?) instead of the butterfly throttle.
From the following year (1991) Ferrari introduced the variable length trumpets and switched back to single injector per cylinder, hence the typical setup with a single central rail as visible on this 043 (1994), V12 3497cc.
That engine had 4 valves per cylinder and butterfly throttle.
The two bars exiting between the cylinders 1 & 2, and the cylinders 5 & 6 are guides for the variation of intakes length, it’s a single carbon part moving vertically, stroke is about 3-4 cm.
Here a close up of the injector and intake runner of the 046/2 (1997), V10 2998 cc :
You can see the guide described above and the gears of the very simple mechanism to lift the trumpets; judging by the length of the guide the stroke was a little larger, in the order of 5 cm.
Here the steering servo, unfortunately the pic is a bit blurred and far from good, I’m sorry but it looked quite ok on the LCD so I didn’t take another one.
