BMW M73
From Wikipedia, the free encyclopedia
The BMW M73 is a V12 SOHC piston engine which replaced the M70 and was produced from 1993-2002.
Design
Compared with its M70 predecessor, the M73 uses an aluminum engine block and cylinder heads.[1] While most other engines in the BMW range had switched to DOHC and 4 valves per cylinder, the M73 used SOHC and 2 valves per cylinder.[2]
Some versions of the engine have two separate Bosch Motronic ECUs, while others use a single ECU.[citation needed]
