What is a Nozzle? Here are Its Functions and Types, Let's Take a Look!

Questions like “what is a car nozzle?” are certainly familiar to find in automotive forums or social media. This is because most car owners in Indonesia are still unfamiliar with this component. To answer that question and curiosity, you can pay attention to the following review.

What is a Car Nozzle? 

A car nozzle is a component (device) of the engine that is related to the fuel supply in the combustion chamber. This component has a shape resembling a tube or pipe with varying diameters according to other components as applications. The tube is used to direct the flow of fluid to the end of the tube (nozzle). In conclusion, the nozzle can be said to be a fuel injector that serves to flow and spray fuel so that the engine can start. 

Functions of a Car Nozzle

The nozzle in a car has various functions. Here are the complete functions.

1. Energy Converter

The nozzle functions to convert thermal energy and pressure into kinetic energy (motion). 

2. Fluid Controller

The nozzle also functions to control the direction, pressure, and flow rate of the fluid.

3. Fluid Angle Director

The next function is to regulate the direction of the spray in the fluid jet section to form a specific angle.

4. Gas Flow Controller

The nozzle can also function to control the flow of gas.

Types of Nozzles in Cars

After you know the functions of the nozzle, it's now time to learn about the types of nozzles. Here are the complete types.

1. Converging Nozzle

The first type is the converging nozzle. This nozzle can make the fluid flow move faster but does not exceed the speed of sound of the fluid. This occurs due to the shape of the nozzle flow that narrows at the fluid flow section.

2. Diverging Nozzle

The next type is the diverging nozzle. This nozzle has a larger diameter compared to the converging nozzle. As it approaches the fluid flow, the diameter of the nozzle becomes larger.

3. Converging-Diverging Nozzle

The next type is the converging-diverging nozzle, or more commonly known as the CD nozzle. The characteristic of this nozzle is its small shape at the beginning and continues to widen at the end. This type of nozzle can increase the fluid flow at the small nozzle section using supersonic speed. No wonder this nozzle is used in jet engines and rockets.

Signs of a Damaged Car Nozzle

After you know the types of car nozzles, you also need to know the signs of a damaged car nozzle. Here are the complete signs.

1. Car Engine Hard to Start

Signs that your car nozzle is damaged can be identified when the car engine is started. If the car engine is hard to start, it could be that your nozzle is damaged or clogged, preventing fuel from being optimally delivered to the engine's combustion section.

2. Car Overheating

The second sign can be marked by the engine easily overheating. This condition is usually caused by a leaking nozzle, so the engine's combustion chamber does not receive the appropriate fuel consumption. This can cause the engine's performance to become heavier, leading to overheating.

3. Weak Car Engine

A damaged car nozzle can also be identified by the weak performance of the engine. This happens because a damaged nozzle cannot deliver fuel according to the needs of the engine's combustion chamber.

4. Excessive Fuel Consumption

The next sign can be identified by excessive fuel consumption. This occurs because the nozzle cannot control the flow of fuel, sometimes resulting in excessive spraying.

If these signs occur in your car, immediately take your car to the nearest Daihatsu workshop for proper handling.
