Wärtsilä Variable Injection Timing

The VIT is an automatic function for Wärtsilä Vasa 32LN engines that controls the injection start depending on the actual engine load and cares for optimum part load fuel consumption.

The VIT injection pump elements are interchangeable with the existing injection pump elements and can be installed during maintenance without any further modifications.

• 2% fuel consumption reduction on part load operation (50%)
• Lower smoke levels at low load operation
• Improved operational availability due to modified plunger design
• Easy installation using exchange pumps or element replacement

The Wärtsilä VIT Injection pump elements can be installed on all Wärtsilä Vasa 32LN engines. The solution is most beneficial for customers regularly operating the engines on part load.
