Vit in sulzer engine. VIT is employed to advance fuel injection timing so that maximum combustion pressure or Pmax is reached at about 85% load. VIT – SULZER ENGINES It is a type of fuel pump control which allows the engine to achieve the designed maximum combustion pressure at a range of 75% to 100% power. The VIT and FQS system performs two main tasks. The only change the Sulzer made was to replace the mechanical control of the VIT by an electronic control in their later engines. No description has been added to this video. VIT has been a traditional feature of Wärtsilä (Sulzer) slow-speed engines allowing to adapt an optimum injection timing over an engine load to various fuel properties having a poor combustion behaviour. How does it improves the Fuel Pump with VIT The sketch above shows the operating principle of the VIT in a fuel pump fitted to the Sulzer RTA engine. As the plunger moves up and down, two pivoted levers operate suction valve and spill valve push rods which open the suction and spill valves as shown. This gives a more efficient engine by lowering the fuel consumption. See the diagram below. Apr 17, 2024 · VIT or Variable Injection Timing is a form of fuel pump control, that enables an engine to operate with the designated maximum cylinder firing or combustion. Hence there is no question of a "super VIT" in a Sulzer engine. Aug 14, 2021 · The Variable Injection Timing (VIT) function of a marine diesel engine comes into play during load dependent adjustment of the combustion pressure. A plain cylinder plunger reciprocates inside the barrel. Mar 24, 2023 · VIT is a traditional feature of Wartsila (Sulzer) slow-speed engines, but it can also be found in some medium-speed engines such as Wartsila 16V32 . May 24, 2017 · The explanation of the main engine fuel pump and VIT is very informative, highlighting the importance of maintenance for efficiency. Feb 21, 2022 · VIT or Variable Injection Timing is a form of fuel pump control, enabling an engine to operate with the designated maximum cylinder firing or combustion pressure from approximately 75% power output to maximum power. The VIT settings for each engine type are specified by the manufacturer and should be checked regularly for proper operation. Marine diesel engine [Fuel Pump 2S], Variable injection timing (VIT) and Super VIT. Dec 10, 2015 · By using specially designed fuel pumps such as sulzer fuel pumps. Why do we need VIT, what is conventional VIT and Super VIT. Similarly, if you're looking to upgrade or sell your vehicle, you can Sell my car for cash in Sydney to get value from it easily. What are its effects. In the seventies when fuel consumption gained more importance Sulzer introduced the so called Variable Injection Timing and Fuel Quality Setting (VIT and FQS) system on its low speed two stroke engines. sneav jlgrtke rpo xcjvb jnm opajd fkzh bhj jmwo ciydix
