Nitrogen (N2) is the most abundant element in our atmosphere, making up about 78% of the air we breathe. Nitrogen plays a significant role in the automotive industry, particularly in improving quality and performance.
Here are several ways in which nitrogen is utilized for these purposes:
Table of Contents
Tire Inflation:
Reduced Pressure Fluctuation: Nitrogen molecules are larger and less prone to permeate through tire walls compared to oxygen. This translates to significantly slower pressure loss, leading to:
Stable handling and predictable responses: Consistent tire pressure maintains optimal contact with the road, improving cornering and braking while minimizing hydroplaning risk.
Increased fuel efficiency: Properly inflated tires offer lower rolling resistance, reducing the energy needed to propel the vehicle, and resulting in better fuel economy.
Extended tire lifespan: Maintaining optimal pressure minimizes uneven wear and tear, prolonging the life of your tires.

Welding and Brazing of automobile components:
Reduced Oxidation and Contamination: Nitrogen creates an inert atmosphere during welding and brazing, preventing oxygen from interacting with the hot metal and compromising the joint’s strength and durability. This leads to:
Stronger and more reliable welds: Improved joint integrity enhances the structural integrity and safety of the vehicle.
Minimized corrosion risk: Reduced oxidation prevents rust and corrosion at weld points, extending the life of the components.
Engine Components:
Reduced Wear and Tear: Nitrogen can be used in place of air in certain engine components, like shock absorbers and pneumatic struts. This is because:
Lower moisture content: Nitrogen is relatively dry compared to air, minimizing internal corrosion and wear on metal components.
Smoother and more consistent operation: Nitrogen offers more predictable damping characteristics, resulting in a smoother and more comfortable ride.
Paint Drying:
Improved Paint Quality and Adhesion: During the car painting process, using nitrogen in the drying booths creates a controlled environment with minimal dust and contaminants. This leads to:
Faster and more uniform drying: Nitrogen prevents uneven drying and solvent trapping, resulting in a smoother, higher-quality paint finish.
Enhanced paint durability: Improved adhesion between the paint and the car’s body reduces the risk of chipping and peeling over time.
Overall, the use of nitrogen in various automotive applications contributes to:
Enhanced safety: Improved tire performance, stronger welds, and reliable engine components contribute to a safer driving experience.
Increased fuel efficiency: Stable tire pressure and improved engine operation can lead to significant fuel savings.
Extended lifespan: Nitrogen helps protect tires, engine components, and paintwork, prolonging the life of your vehicle.
Improved driving experience: Stable handling, smoother riding, and consistent performance enhance the overall driving experience.
While the benefits of using nitrogen in various automotive applications are undeniable, it’s important to note that they may not be necessary or cost-effective in all cases.
Nitrogen Generators: Producing N2 on Demand
Nitrogen generators are machines that separate nitrogen molecules from compressed air. These generators offer several advantages over relying on compressed nitrogen cylinders or bulk liquid nitrogen deliveries:
Cost-effective: Generating nitrogen on-site is typically cheaper than buying cylinders or deliveries, especially for high-volume needs.
Convenience: No need to order, handle, or store bulky cylinders or tanks.
Reliability: Continuous supply of nitrogen, eliminating concerns about running out.
Environmental benefits: Reduces carbon footprint compared to transportation of cylinders or liquid nitrogen.
There are two main types of nitrogen generators:
Pressure Swing Adsorption (PSA): Uses carbon molecular sieves to selectively adsorb oxygen and other gases, allowing nitrogen to pass through.
Membrane: Employs hollow fibers with selectively permeable membranes that allow nitrogen to pass through while blocking other gases.

Nitrogen generators can be used in various applications, including:
Food processing: Packaging, freezing, and modified atmosphere packaging to extend shelf life.
Pharmaceuticals: Manufacturing and packaging of drugs and medical supplies.
Electronics: Semiconductor and microchip production.
Chemical processing: Inert atmosphere for various chemical reactions.
Laboratories: Carrier gas for analytical instruments.
Automotive industry: Tire inflation for improved fuel efficiency and tire lifespan.
In summary, nitrogen, the often-overlooked element, plays a crucial role in our everyday lives and various industries. And nitrogen generators provide a convenient, cost-effective, and environmentally friendly way to access this versatile gas on demand.
