Application
Based on a pre-chamber ignition system, air/fuel mixture charging, and a four-valve cylinder head, the type 6 gas engines were designed to allow for continuous performance improvements over time.
  • The four-valve cylinder head, included in the centrally located purged pre-combustion chamber, minimizes charge-exchange losses, and offers highly efficient and stable combustion and optimal ignition conditions.
  • The ignition energy of the spark plug is amplified in the pre-combustion chamber, which enables the highest efficiency, lowest NOx emission values, and stable and reliable combustion.
  • The TecJet? gas dosing valve offers a high degree of electronic control and accuracy, rapid response time and adjustment of air/gas ratio, and a large adjustable calorific value range. The camshaft is equipped with Miller valve timing, which enables high efficiency through optimized ignition timing, reduces maximum compression temperature, and increases the safety margin to knocking limits.
