The first two digits (99) denote the year of manufacture. In this case it is 1999.

The next two digits (01) are the month of the year, which is January.

The following two digits (15) are the day of the month. In this case the 15th.

The final two digits designate the plant and assembly line.

Therefore, this engine’s manufacture date was January 15, 1999.
