There are also modifications to the con rod and piston assembly aimed at reliability rather than outright performance.
As you are reducing the weight by 23% compared to aluminium this means that the con rod can be re-designed as it doesn't have to be quite so strong as the inertia is less.
But at the other end of the spectrum, a different grade of the material also goes into high-critical parts like bearing caps, con rods and helical gears.
There are sinter-forged con rods and a forged steel crank to deal with the furbocharged loads.
The motor also boasts a reinforced engine block with increased coolant flow, a forged steel crankshaft, high-strength con rods, improved pistons, a modified sump and hollow, sodium-filled intake and exhaust valve stems.
Water doesn't compress and the piston in effect hits a wall, bending or breaking a con rod and possibly shattering the engine block.
Forged powder metal con rods, while normal practice for gasoline engines, are novel in diesel applications.
The cylinders in the aluminum block have interference-fit cast iron liners; aluminum pistons with cracked-steel con rods ride in them.
The con rod went through the bottom of the motor and scraped on the track.
The problem was complicated because the con rods were just thrown into the bins, so there was considerable overlapping; the robot would need to determine which piece was on top and grasp it.
The con rods are high-strength forged steel that's treated with a carbon hardening process.
But with the angle split rods on the 6.0L, the lower bearing cap mates to the main part of the con rod with cap screws secured in blind threaded holes.
