Connecting Rod: Description and Operation

Pistons/Connecting Rods:

Asymmetrical design pistons continue to be used with the M52 engine. These pistons have a wider skirt on the thrust side.

This allows the piston to be manufactured with a shorter skirt while still maintaining the required strength and rigidity for the 2.8 liter displacement.

This design also offers the advantage of weight savings which reduces friction and improves fuel economy.

Pistons/Connecting Rods:

The connecting rods have been redesigned. Weight-optimized rods are used that are 12% lighter than the M5OTU rods.
