Description
Wartsila L20 plunger introduction:
Plungers are typically made of high-strength alloy materials, with precision-machined and hardened surfaces to withstand high pressure, high temperature, and wear. Their working principle involves the plunger reciprocating within the pump body, changing the sealed volume to achieve fuel intake, compression, and injection.
