In 1970s and early 1980s, Sulzer Z40-engine has established itself worldwide as one of the most successful four-stroke medium speed Diesel engines. Some design features, such as the high mechanical safety level, the rotating piston and the intensively cooled combustion chamber components have contributet to the success of the engine among clients.

These facts have encouraged Sulzer to start the necessary work for a new development step of the Z40-engine, aiming at the following targets:

  • Utilization of the proven design features of the Z40
  • Improved fuel consumption to satisfy market requirements
  • Improved reliability in heavy fuel service
  • Increased cylinder output without reduction of the safety margin
  • Manufacturing costs as low as possible, achieved by standardization and simplification
  • Further improvements for easy servicing

This further developed engine was called ZA40 (ZAL40 for the in-line, ZAV40 for the V-engine respectively).

The ZA40 was produced in the following cylinder numbers and configurations:

  • In-line engines: 6ZAL40, 8ZAL40 and 9ZAL40
  • Vee-form engines: 12ZAV40 and 16ZAV40

The ZA40 engine used to be manufactured in these four following works:

  • ZGODA ŚWIĘTOCHŁOWICE, POLAND
  • NSFR MANTES (CCM), FRANCE
  • HITACHI ZOSEN, JAPAN
  • WARTSILA, FINLAND
