I came across this old yesteryears Bentley at an exhibition.
It was a good opportunity to study the vehicle design and dynamics.
This picture shows the engine and the arrangement of carburetors and the ignition coil. From the ignition coil we can make out that it is a four cylinder engine.
Well, today with the arrival of MPFI engines the days of ignition coils are gone and the engines are more reliable than they were earlier.
