Aston Martin Pistons

Here’s a closer look at the pistons for our 1953 Aston Martin DB2/4.

This design focuses on optimisation for strength as shown by the detailed internal structure.

• Internal Architecture Of The Piston:
  • Green Component: structural reinforcement
  • Orange Zones: critical regions of contact
  • Blue Feature: cavity for oil passage or thermal management.

• Side view of piston showing its external features:
  • Ring Grooves: Where the piston rings would sit to seal the combustion chamber.
  • Pin Hole: The circular opening is for the wrist pin, connecting the piston to the connecting rod.
  • Cutouts or Skirt: The large open sections reduce weight as these pistons are designed for high-performance engines.
  • Dome Design: The slightly domed crown is to improve efficiency or power.
