Structural, running gear, combustion chamber, fuel injection,
turbocharging and scavenge air system design details are similar to
those of the RTA84C and RTA96C engines described below. The large
stroke-to-bore ratio of the RTA84T, however, allows a relatively deeper
combustion chamber with more freedom in the layout of the fuel
spray pattern. The semi-built crankshaft has to cater for the longest
stroke ever applied in a Sulzer engine; to limit the crankshaft weight
for production, assembly and transport, the main journals and crankpins
are bored. The design of the crank has a good transverse width at the
upper part of the web, allowing the latter to be slim longitudinally.
