What is the purpose of a catalytic converter?

A catalytic converter is designed to reduce harmful emissions generated by a vehicle's engine by converting toxic gases, such as carbon monoxide, nitrogen oxides, and hydrocarbons, into less harmful compounds like carbon dioxide, nitrogen, and water vapor. This helps to minimize air pollution and meet environmental regulations regarding vehicle emissions.

Describe the function of a transmission.

The function of a transmission is to transfer power from the engine to the wheels, allowing the vehicle to change speed and direction. It does this by adjusting the gear ratio, providing the right amount of torque for the driving conditions. The transmission enables the vehicle to accelerate, decelerate, and maintain a consistent speed by shifting gears based on the driver's input and road conditions.

What is the difference between horsepower and torque?

Horsepower is a measure of how quickly work is done over time, while torque is a measure of the rotating force produced by an engine. In simpler terms, horsepower indicates how fast work can be done, while torque indicates the actual force available to rotate an object, such as a wheel. Horsepower is a function of torque and engine speed, with higher torque typically resulting in higher horsepower at higher engine speeds.

Define ABS braking system.

An Anti-lock Braking System (ABS) is a safety feature in vehicles that helps prevent wheels from locking up during braking, allowing the driver to maintain control and steer the vehicle effectively in emergency braking situations. ABS works by automatically modulating the brake pressure to each wheel, ensuring that they continue to rotate and providing the driver with safer stopping capabilities on various road surfaces.

What is the purpose of an air filter?

The purpose of an air filter is to remove contaminants, such as dust, pollen, bacteria, and other particles, from the air before it enters an engine or a room. This helps to improve air quality, prevent damage to machinery, and ensure that the air being circulated is clean and safe to breathe.

Explain the role of a differential in a car.

The differential in a car is a crucial component that allows the wheels to rotate at different speeds while maintaining traction and stability. It works by distributing power evenly to the wheels, especially when turning or encountering uneven road conditions. This helps prevent tire wear, improves handling, and ensures smooth operation of the vehicle. Ultimately, the differential plays a key role in optimizing performance and safety during driving.

Define hill start assist feature.

Hill start assist is a vehicle feature that helps prevent a vehicle from rolling backward when starting on an incline. It automatically holds the brakes for a few seconds after the driver releases the brake pedal, giving them time to accelerate without the risk of rolling back. This feature is especially useful in situations where driving uphill on a steep gradient may make it challenging for the driver to transition smoothly from the brake pedal to the accelerator.

What does the term "MPG" stand for?

MPG" stands for "miles per gallon," which is a unit of measurement used to determine the fuel efficiency of a vehicle by indicating how many miles it can travel on one gallon of fuel.

Describe the function of a timing belt.

A timing belt is a critical component that synchronizes the rotation of the crankshaft and camshaft in an internal combustion engine. This synchronization ensures that the engine's valves open and close at the right times during the combustion process, allowing for the optimal performance of the engine. Without a functioning timing belt, the engine's valves may not open and close properly, leading to engine misfires, decreased performance, and potentially catastrophic damage.

What is the purpose of a radiator in a car?

The purpose of a radiator in a car is to help cool down the engine by transferring heat away from it. As the engine operates, it generates a lot of heat, and the radiator uses a liquid coolant to absorb this heat and then dissipate it through the radiator's fins, which are exposed to airflow. This helps prevent the engine from overheating and ensures it operates at the optimal temperature for proper functioning.
