Ja, de beginletter is de motorfamilie.
t is dan ook F9Q:
Diesel = 9, 8 of 16 maakt niet veel uit. Dat zitw eer in de laatste 3 cijfers.
Alphanumeric
The system in use since the mid-1980s is of the format XnY-zzz where
* X is a letter specifying the engine family
* n is a one-digit code specifying the engine architecture as follows:
1. Petrol engine with single-barrel carburetor and parallel valves (a layout often but not always associated with an overhead valve design)
2. Petrol engine with double-barrel carburetor and parallel valves
3. Petrol engine with single- or multi-point fuel injection and parallel valves
4. Petrol engine with four valves per cylinder
5. Petrol engine with single-barrel carburetor and crossflow valve layout
6. Petrol engine with double-barrel carburetor and crossflow valve layout
7. Petrol engine with single- or multi-point fuel injection and 2 or 3 valves per cylinder in a crossflow layout (includes also an early 16-valve version of the F-type engine)
8. Diesel engine with indirect injection (prechamber)
9. Diesel engine with direct injection
* Y is a one-letter indicator of displacement:
A: under 750cc
B-U: from 750 to 2250 cc in 50-cc, then 100-cc increments as displacement increases
V-Z: above 2250 cc in increments larger than 100cc
* zzz is a three-character alphanumeric code (usually starting with 7 or A) referring to key details of the variant's configuration (e.g., turbocharged, implemented in a specific vehicle, manual or automatic transmission, catalytic converter or not, etc. An odd number refers to an engine configured for automatic transmission, while an even number is meaning manual gearbox.)
