Mercedes-Benz M110 engine

The Mercedes-Benz M110 was a family of straight-six petrol engines with a double overhead camshaft, a crossflow cylinder head and two valves per cylinder, built by Mercedes-Benz in the 1970s and 1980s. Every M110 displaced 2,746 cc, with a bore of 86 mm and a stroke of 78.8 mm, and the camshafts were driven by a duplex roller chain. The M110.92x and .93x versions used a Solex 4A1 carburettor, while the .98x and .99x versions were fuel injected, with Bosch D-Jetronic up to the .983 and K-Jetronic from the .984. It powered the 280 in the W114, W116 and W123 ranges, the 280 SL and SLC and the 280 S in the W126, and the single-cam M103 replaced it from 1986.
