Automotive ignition system rubber components

Automotive ignition system components

Common automotive ignition system components, where rubber seals are used

• Ignition Coil: The ignition coil converts the low voltage of the battery into high voltage, which is used to ignite the vehicle’s fuel mixture. Where the ignition coil is installed, a rubber seal may be used to ensure a tight seal between the coil and other components, preventing moisture or dust from entering.
• Spark Plug: The spark plug is the component that delivers electrical current to the combustion chamber to ignite the fuel mixture. The ignition plug is usually made of metal and ceramic, but a rubber seal may be used in the part that contacts the cylinder head to ensure a tight seal between the ignition plug and the cylinder head and prevent gas leakage.
• Ignition Switch: The ignition switch is used to control the ignition and shutdown of the car, usually located behind the steering wheel. Where the ignition switch is mounted, a rubber seal may be used to protect the interior of the switch from dust, moisture, and other contaminants.

• Automobile ignition coils often use rubber seals to ensure sealing with other components.
• Sealing: When installing the ignition coil, the rubber sealing ring fills and seals the gap between the coil and other components, such as the connection between the ignition coil and the ignition plug hole or the ignition coil and the ignition module. It ensures that moisture, dust and other impurities are prevented from entering the ignition system and causing electrical malfunction or damage.
• Shockproof and anti-vibration: The rubber sealing ring has certain elasticity and shock-absorbing properties, which can reduce the shock and vibration of the ignition system during car operation. This helps protect the stability and reliability of the ignition coil and its internal components.
• Insulation: The rubber seal forms an insulating layer around the ignition coil to prevent leakage or interference of current. This helps ensure the electrical performance and proper operation of the ignition coil.
• Rubber seals are usually made of rubber materials that are resistant to oil, heat, and chemicals, such as NBR (nitrile butadiene rubber) or EPDM (ethylene propylene rubber). Seal size and shape will vary depending on specific ignition coil design and installation requirements.

Automobile ignition coils can also use EPDM (ethylene propylene rubber) seals.

• Temperature resistance: EPDM has excellent high temperature and low temperature resistance. It can maintain its elasticity and sealing effect over a wide temperature range, adapting to different operating temperature conditions in the ignition system.
• Oxidation resistance: EPDM has good oxidation resistance and can resist the erosion of oxygen and ozone. This allows it to maintain its performance and sealing effectiveness over long periods of use and exposure to the outside environment.
• Chemical Resistance: EPDM has good resistance to many common chemicals and solvents, including acids, bases, salts and some oils. This makes it resistant to chemical attack and corrosion in ignition systems.
• Aging resistance: EPDM has good aging resistance and can maintain its performance and sealing effect under long-term use and exposure to environmental factors such as ultraviolet rays and oxygen. This makes it widely used in outdoor and harsh environmental conditions.
• Elasticity and plasticity: EPDM has good elasticity and plasticity, adapting to different shape and size requirements between ignition coils and other components. It provides a reliable sealing effect and has high resistance to compression and rebound.

EPDM sealing rings are usually made of EPDM materials that comply with relevant standards in the automotive industry to meet the requirements of ignition coils. Seal size and shape will vary depending on specific ignition coil design and installation requirements.

Rubber seals are often used on car ignition switches. The ignition switch is the switch used to control the ignition and shutdown of the car. It is located behind the steering wheel or on the driver’s side panel of the vehicle.

• Sealing: When installing the ignition switch, the rubber seal fills and seals the gap between the switch and the panel to ensure that moisture, dust and other impurities are prevented from entering the inside of the switch. This helps prevent moisture and contaminants from affecting the switch and keeps the switch functioning properly.
• Protective: The rubber seal forms a protective layer around the ignition switch, protecting the inside of the switch from the outside environment. It blocks moisture, dust, grease, and other contaminants from entering the switch, thereby reducing wear and the possibility of switch failure.
• Shockproof and anti-vibration: The rubber seal has certain elasticity and shock-absorbing properties, which can reduce the shock and vibration of the ignition switch during car operation. This helps protect the stability and reliability of the switch’s internal circuitry and connected components.

Automobile spark plugs often use rubber gaskets. The ignition plug is a component installed on the engine cylinder head to ignite the mixture and drive the cylinder. The rubber sealing gasket plays the following roles at the installation position of the ignition plug:

Sealing: The rubber sealing gasket is located between the ignition plug and the cylinder head, filling and sealing the gap between them. It ensures to prevent the compressed gas and combustion products in the combustion chamber from leaking around the cylinder head to maintain the normal combustion process and the sealing of the cylinder.

Protective: The rubber sealing gasket forms a protective layer around the ignition plug, protecting the ignition plug and cylinder head from the external environment. It blocks moisture, dust, grease and other contaminants from entering the space between the glow plug and cylinder head, reducing the potential for corrosion and damage.

Thermal Insulation: The rubber gasket forms an insulating layer between the ignition plug and the cylinder head, helping to prevent the conduction of heat. This reduces heat exchange between the glow plug and cylinder head, improving ignition system efficiency and performance.

Rubber gaskets are usually made of rubber materials that are resistant to high temperatures, oils and chemicals, such as NBR (nitrile butadiene rubber) or Viton (fluorine rubber). Gasket size and shape will vary depending on the specific glow plug and cylinder head design to ensure proper fit and sealing.

Car ignition plug Viton

Viton is a special rubber material also known as fluoroelastomer. It has excellent resistance to high temperatures, oils and chemicals and is therefore widely used as glow plug gaskets in automotive ignition systems.

High temperature resistance: Viton has excellent high temperature resistance and can maintain its elasticity and sealing effect in high temperature environments. It can withstand the high pressure and high temperature in the high temperature combustion chamber and will not cause deformation or failure due to high temperature.

Chemical Resistance: Viton has excellent chemical resistance and can resist the attack of a variety of chemicals, including fuel, lubricants, coolants and other common automotive chemicals. This makes it effective in preventing chemical penetration and leakage in glow plug gaskets.

Oil resistance: Viton has excellent oil resistance and can maintain its performance and sealing effect in grease and lubricating oil environments. It resists corrosion and dissolution of oil and ensures a tight seal between the ignition plug and the cylinder head.

Elasticity and Resilience: Viton has good elasticity and resilience properties and can adapt to different shape and size requirements between the ignition plug and the cylinder head. It can provide reliable sealing effect and maintain its original shape and size, remaining stable even under high temperature and high pressure working conditions.

Aging Resistance: Viton has excellent aging resistance, maintaining its performance and sealing effect over long-term use and exposure to environmental factors such as UV rays and oxygen. This allows it to be used for a long time under the harsh working conditions of automobile engines without being prone to aging and damage.

In general, Viton material is widely used in automotive ignition plug gaskets because it can provide excellent resistance to high temperature, oil and chemical corrosion, ensuring the reliability and sealing of the ignition system.
