Engine System

The engine converts fuel into energy to power the vehicle. The engine system consists of many different parts including the crankshaft, cylinders, pistons, valves, and more. Within the engine system is the fuel system, which is responsible for delivering fuel to the engine. Regular maintenance of the engine system is crucial to ensure optimal performance and longevity of the vehicle.

Transmission System

The transmission system is an essential part of a car’s powertrain and is responsible for transferring power from the engine to the wheels. It controls the torque and speed of the wheels, enabling the car to move at different speeds and in different directions. The transmission system consists of the gears, clutch, and torque converter. A properly functioning transmission system is essential for a smooth and safe driving experience.

Suspension System

The suspension system in a car is a set of components that work together to absorb shock and vibrations from the road, providing a smooth and comfortable ride for passengers. It consists of springs, shock absorbers, struts, and other components that help to maintain the stability and control of the vehicle while driving.

Brake System

The brake system in a car slows down and stops the vehicle. The most common type of brake system is the hydraulic brake system, which uses fluid to transfer force from the brake pedal to the brake pads, which then apply pressure to the rotors or drums to slow or stop the vehicle. Within the brake system, there is a brake pedal, brake booster, master cylinder, brake lines, calipers, and brake pads.

Electrical System

The electrical system provides power to lights, the radio, and other electronic devices in the car. It consists of various parts, including the battery, starter, and alternator. The battery provides power to the starter, and the alternator gives that battery the energy it needs to power the vehicle.

Exhaust System

The exhaust system removes harmful gases from the engine and reduces emissions as well as noise. The exhaust system is made up of the catalytic converter, muffler, and exhaust pipes. 

Fuel System

The fuel system stores the fuel until it is needed, delivers it to the engine, and mixes it with air to provide the necessary energy to operate. Its components include the fuel tank, fuel pump, fuel filter, fuel injectors, fuel pressure regulator, throttle body, and fuel lines.
