3. **Signs of a Failing Ignition Coil:** Ignition coils can fail over time due to factors such as high temperatures, vibrations, and age. Some common signs of a failing ignition coil include engine misfires, rough idling, difficulty starting the engine, reduced fuel efficiency, and engine stalling. If you experience any of these symptoms, it is essential to have your ignition system checked by a professional mechanic.

3. **Enhanced Engine Performance**: A properly functioning oxygen sensor ensures that the engine operates at its peak performance. By maintaining the correct air-fuel ratio, the engine can deliver optimal power output and smooth operation.

In conclusion, universal joints play a crucial role in transmitting rotary motion between misaligned shafts in various mechanical systems. By understanding their function, types, applications, and important considerations, engineers and designers can effectively integrate universal joints into their designs to improve overall system performance and efficiency.

- **Poor Fuel Economy**: If the oxygen sensor is not functioning correctly, the engine control unit may not be able to adjust the air-fuel mixture properly, leading to decreased fuel efficiency.
- **Check Engine Light**: A faulty oxygen sensor can trigger the check engine light on the dashboard. It is essential to have this issue diagnosed promptly to prevent further damage to the engine.
- **Rough Idling or Poor Performance**: A failing oxygen sensor can cause the engine to run rough or misfire, affecting overall performance and drivability.

Oxygen sensors are a crucial component of modern vehicle engine systems, playing a vital role in ensuring optimal fuel efficiency and reducing harmful emissions. These small sensors are located in the exhaust system and are responsible for Data Logging measuring the amount of oxygen in the exhaust gases.

Introduction:
The exhaust manifold is a crucial component of a vehicle's exhaust system that plays a significant role in the efficient operation of an engine. Understanding the functions, types, and maintenance of exhaust manifolds is essential for ensuring optimal performance and longevity of a vehicle.

What is Brake Fluid?
Brake fluid is a specially formulated type of hydraulic fluid that is designed to transfer force and pressure from the brake pedal to the brake components, such as the calipers and wheel cylinders. It is a non-compressive fluid, meaning that it does not compress under pressure, allowing for the effective transfer of force through the brake system.

Applications of Starters:
1. Bread Making: In bread baking, starters such as sourdough are used to leaven the dough and add distinct tangy flavors. The wild yeast and lactobacilli present in sourdough starters help in the fermentation process, resulting in a well-risen, flavorful loaf of bread.

Introduction:
Universal joints, also known as U-joints, are mechanical components that provide flexibility in transmitting rotary motion between two shafts that are not in a straight line with each other. They are commonly used in various mechanical systems where shafts need to change their angles or misalignments while transmitting torque. In this article, we will explore the function of universal joints, their types, applications, and important considerations for their use.

Importance of Brake Fluid Maintenance:
Proper maintenance of brake fluid is crucial for the overall performance and safety of the vehicle. Old or contaminated brake fluid can lead to several issues, including:
1. Reduced braking performance: Contaminated or degraded brake fluid can cause a decrease in braking efficiency, leading to longer stopping distances and reduced overall safety.
2. Component damage: Old brake fluid can cause corrosion and wear on brake system components, potentially leading to costly repairs or replacements.
3. Brake system failure: In extreme cases, neglected brake fluid can lead to brake system failure, resulting in a complete loss of braking ability and a serious safety hazard.

In conclusion, the ignition coil plays a crucial role in the proper functioning of a vehicle's ignition system. Understanding the importance of the ignition coil, recognizing the signs of a failing coil, and performing regular maintenance can help ensure the reliability and performance of your vehicle. If you suspect any issues with your ignition system, it is best to consult a qualified mechanic for a thorough inspection and potential replacement of the ignition coil.

Functions of Brake Fluid:
1. Transfer of force: Brake fluid transmits the force applied by the driver on the brake pedal to the brake components, leading to the activation of the brakes and the deceleration of the vehicle.
2. Lubrication: Brake fluid helps to lubricate moving parts within the brake system, reducing friction and wear on components like caliper pistons and wheel cylinders.
3. Corrosion prevention: Brake fluid contains additives that help prevent corrosion and rust within the brake system, ensuring its longevity and proper functioning.
