What are the types of fuel injector nozzles?

Types of Injector Nozzle There are three basic types of nozzle in common use. These include (a) The pintle type, (6) The hole type, and (c) Two-stage injection (Pintaux) type. The Pintle Type Injector.

What is diesel fuel injection nozzle?

The injector hole is the final element of the fuel injection system before the fuel enters the combustion chamber. As such, the size and shape of the nozzle hole can play a critical role in the emissions and performance of the diesel engine.

Which is not the type of nozzle used in diesel fuel injector?

Explanation: The circumferential hole nozzle is used in open type combustion chambers and single or multi hole nozzle are not used.

What are the different types of nozzles used in diesel engine?

Types of Nozzle in IC Engine : Pintle Nozzle, Single Hole Nozzle, Multihole Nozzle, Pintaux Nozzle.

What is fuel injector nozzle?

An injector nozzle is a fine sprayer through which fuel is injected into an engine. The top of the injector nozzle has a lot of holes to deliver a spray of diesel fuel into the cylinder.

What is fuel nozzle?

A fuel nozzle for a gas turbine engine injects a liquid fuel flow from a liquid fuel passage in the swirler vane. An air flow over the swirler vane atomizes the liquid fuel flow to form a fuel air mixture. The fuel nozzle eliminates the need for a conventional air blast atomizer.

What are the different types of nozzles?


  • Nozzle.
  • The Nozzle Tip is one of the most important and least expensive part of a spraying system. Adjustable nozzle.
  • Double swirl spray nozzle.
  • Selecting a spray nozzle.
  • Hollow cone nozzles-Disc and core type.
  • Flat fan nozzles.
  • Floodjet nozzles.
  • Adjustable nozzles.

What are the six types of diesel injectors?

The main types of injection systems include pump-line-nozzle, unit injector, and common rail….Diesel combustion is highly influenced by:

  • Injected fuel quantity,
  • Start of injection,
  • Exhaust gas recirculation (EGR) when applied,
  • Charge air temperature and pressure.

What are the components of diesel injection system?

The low-pressure components include the fuel tank, fuel supply pump and fuel filter. The high-pressure side components include a high pressure pump, accumulator, fuel injector and fuel injector nozzle.
