F16 starter type?

[yk1988]

Anyone knows what type of starter is on the F16? If it's using the TS type, Is it monitoring the engine RPM(=flywheel RPM) when you push the start button?


Denso:

1. Advanced Engagement (AE) Starter:

The advanced engagement starter works like a typical starter, which when it is energized shifts pinion forwards, engaging with the flywheel and starts to rotate. Denso claims the advanced starter to have longer life due to development in electrical brushes, which results in up to 10 times higher durability compared to conventional starter. Denso also claims that development of unique structure and pinion spring mechanism has reduced friction between pinion and ring gear noticeably. Working principle of start-stop technology is as following. The engine is shutdown by cutting the fuel supply, when vehicle brakes are applied and the vehicle is at standstill and the engine reaches to zero rpm. After this point, the starter is reenergized to restart
the engine by stepping on the accelerator pedal. This system is not capable of
change of mind situations as the engine needs to be standing at zero rpm, so there is the some delay in the restart time.

2. Tandem Solenoid (TS) Starter
Denso tandem solenoid consists of co-axial dual solenoid for independent control of the starter’s pinion gear shifting mechanism and motor rotation. One solenoid engages the pinion gear with flywheel ring gear and the other energizes the motor. Special software is used to control the timing and synchronization aspects for pinion gear shifting into the spinning flywheel; possibly with a crankshaft position sensor because as the flywheel is coming to a stop, its clockwise rotation may be combined with counterclockwise oscillation, increasing the complexity for engagement strategy. At NAIAS 2011 exhibition Denso has exhibited a sensor that can identify these oscillation and
precisely determine crankshaft position. The tandem solenoid starter is capable to adapt for driver change of mind as it does not needs to wait for the engine speed to reach zero speed before restarting and also as it can engage into a moving flywheel, allowing quicker restart times as compared to Advanced Engagement starter. Another salient feature of the tandem solenoid starter is being of same size as that of advanced engagement starter.

It's made by Bosch... as to what type, I have no idea.
