The primary function of an air filter is to prevent dirt, dust, and other airborne particles from entering the engine. This helps protect the engine from damage and ensures its smooth operation.

Diesel oil is specifically designed for diesel engines and is not typically used in gasoline engines. Synthetic oil, mineral oil, and semi-synthetic oil are all common types of engine oil used in gasoline-powered vehicles.

The spark plug is responsible for igniting the air-fuel mixture in the combustion chamber, initiating the combustion process that powers the engine.

A faulty oxygen sensor can cause a variety of symptoms, including increased fuel consumption, rough idling, and illumination of the check engine light. These symptoms are all indicators that the oxygen sensor is not functioning properly and needs to be replaced.

The primary function of a catalytic converter is to reduce harmful emissions, such as carbon monoxide, hydrocarbons, and nitrogen oxides, from the exhaust system of a vehicle. It converts these pollutants into less harmful substances before they are released into the atmosphere.

Mineral oil is not a type of brake fluid. DOT 3, DOT 4, and DOT 5 are all common types of brake fluid used in vehicles.

The timing belt is responsible for synchronizing the movement of the crankshaft and camshaft, ensuring that the valves open and close at the correct times during the engine cycle.

DCT is not a common type of transmission. Manual transmission, automatic transmission, and CVT are all more common types of transmissions found in vehicles.

The primary function of a radiator is to cool the engine coolant, which in turn helps regulate the temperature of the engine and prevents overheating.

Run-flat tires are not as common as all-season, summer, and winter tires. They are designed to allow a vehicle to continue driving for a limited distance even after a puncture or loss of air pressure.

The primary function of a suspension system is to absorb shocks and vibrations from the road, providing a smoother and more comfortable ride for passengers.

Spider injector is not a common type of fuel injector. Port fuel injector, direct fuel injector, and throttle body injector are all more common types of fuel injectors used in vehicles.

The primary function of a fuel filter is to remove dirt, debris, and other contaminants from the fuel before it enters the engine. This helps protect the engine from damage and ensures its smooth operation.

Brake fluid is not a type of engine coolant. Water, antifreeze, and glycol are all common components of engine coolant.

The battery in a vehicle serves multiple purposes. It provides electrical power to the starter motor to start the engine, powers the lights and accessories, and stores electrical energy for use when the engine is not running.
