Major systems of a car include the body and frame, engine, transmission, suspension systems, wheels, and tires, control systems, and electrical systems.
The body provides space for the driver, passengers, and cargo, while the frame is the main supporting structure.
Cars can have either a unibody construction or a body-on-frame construction, with most modern cars using the former.
The engine, usually located in the front of the vehicle, converts energy into mechanical energy to propel the car.
The most commonly used engine type in automobiles is the internal combustion engine (ICE), which relies on the combustion energy of gasoline or diesel fuel.
The video explains the basics of car anatomy, including the internal combustion engine and transmission system.
02:18
Internal combustion engines operate on a four-stroke cycle: intake, compression, power, and exhaust.
The engine has various subsystems such as the intake system, exhaust system, fuel supply system, and cooling system.
The torque generated by the engine is transferred to the transmission system via a flywheel.
Transmissions connect the engine to the drive wheels and can be manual or automatic.
The type of wheel drive (e.g., front-wheel drive) affects the structure and composition of the transmission system.
The video explains the different types of wheel drive and the components of the suspension system in a car.
04:35
The powertrain consists of the engine and transmission system.
Rear-wheel drive is another type of wheel drive.
All-wheel drive transmission supplies torque to both axles.
The suspension system includes the wheel hub, spring, shock absorbers, suspension links, arms, and beams.
MacPherson struts are commonly used in the front suspension, while the rear axle may have a semi-independent suspension with a torsion bar.
Car control systems include the steering system, braking system, engine control, and transmission control.
06:55
The steering system is used to change the direction of the car's movement.
The braking system is used to slow down, stop the car, and keep it in place.
Engine control is used to alter the engine torque.
Transmission control is required to disconnect the engine and transmission and select the desired gear or gearbox mode.
Electrical equipment in cars includes power sources, power consumers, electrical wiring, and auxiliary elements.
Power sources are the battery and the generator.
Power consumers include appliances like headlights, starter motor, and engine control unit.
Electrical wiring connects various components of the electrical system.
Auxiliary elements include relay and fuse boxes, buttons, and switches.
00:04In this video, we will go  over the anatomy of a car. 
00:09The following major systems  are included in the vehicle: 
00:13the body and frame 
00:17the engine
00:19the transmission
00:23suspension systems, wheels, and tires.
00:27Control systems
00:31Electrical systems 
00:34The engine subsystems and the climatic equipment  are the only remaining pieces of equipment. 
00:41Let’s take a look at the car’s  major components and assemblies.
00:46It may appear complicated now, but we are  going to explore each system in greater detail. 
00:56So, let’s look at car assemblies.
01:00We’ll begin with the body and frame.
01:04This is the body.
01:09It provides space for the  driver, passengers, and cargo. 
01:15This is the body together with all  auxiliaries and decorative elements.
01:20Next comes the frame. 
01:22It is the main supporting structure to  which all other components are attached. 
01:27It can be a body-on-frame  or a unibody construction. 
01:33The unibody combines the functions  of the body and the frame. 
01:38Most modern cars use this type of construction. 
01:43Body-on-frame vehicles are much rarer  and primarily comprise off-road SUVs.
01:51The next vehicle system is the engine. The engine is usually located in the front of the vehicle.
01:58The engine converts one form of energy into mechanical energy,  which is then used to propel the car. 
02:07The internal combustion engine (ICE) is the  most commonly used engine type in automobiles. 
02:13Such engines rely on the combustion  energy of gasoline, diesel fuel,  
02:18or, in rare cases, another kind of fuel. 
02:23Electric and hybrid motors are  also becoming increasingly popular. 
02:30You can see a four-cylinder, sixteen-valve  gasoline internal combustion engine. 
02:36This engine's operating cycle  consists of four strokes. 
02:401- Intake, 2 - Compression, 3 - Power, 4 - Exhaust 
02:47The engine has numerous subsystems, such  as the intake system,
02:53exhaust system,
02:56fuel supply system,
03:00cooling system, and others.
03:03The internal combustion engine  generates mechanical work,  
03:06and the torque is then transferred to  the transmission system via a flywheel.
03:13The transmission is the device that  connects the engine to the drive wheels. 
03:20It transfers, changes, and distributes  torque to the drive wheels. 
03:27Transmissions are classified  based on the type of gearbox. 
03:33The manual gearbox requires the driver  to select and change gears by using a  gear shift lever and a clutch pedal.
03:41In case of the automatic gearbox, to travel forwards, the driver only needs to shift the selector into the Drive mode. 
03:49Further gear changes do not  necessitate driver intervention. 
03:54The type of wheel drive is another significant  distinction between transmission systems.
04:00You can now see a vehicle with front-wheel drive.
04:03Depending on the type of wheel drive, transmissions can have a variety of structures and compositions. 
04:10A front-wheel drive manual transmission  includes the following components: 
04:15the clutch, manual gearbox 
04:18final drive and differential and axle shafts. 
04:23The clutch, final drive and differential are all  contained within the same housing as the gearbox. 
04:31Now we can see how the engine  and the transmission interact. 
04:35The combination of the engine and the  transmission system is called the powertrain.
04:42Rear-wheel drive is another type of wheel drive. Such transmissions also include a propeller shaft. 
04:49The final drive and differential are located  on the drive axle, outside the gearbox housing.
04:57And this is an all-wheel drive transmission.
05:03In this case, torque is supplied to  both axles, full time or on demand.
05:07Its components also include a transfer case, which can be installed in the  same housing as the gearbox. 
05:15The differential, final drive, and propeller  shaft are duplicated on the driving axles. 
05:25Let’s return to the front-wheel drive  transmission and move on to the next systems.
05:30The suspension system, wheels, and tires  help a vehicle move along a road and receive  
05:36and absorb the impact from various bumps,  making driving safer and more comfortable. 
05:43First, let's take a quick  look at the wheels and tires. 
05:49Wheels can be made from a variety of  materials and in a variety of styles. 
05:53They are surrounded by tires,  creating an air-filled chamber. 
05:57Sometimes tires are also  equipped with an inner tube. 
06:02Let’s go back to the suspension system. The suspension includes: 
06:07the wheel hub. This is a wheel hub mounted on a steering knuckle. 
06:12The spring. A coil spring in our case. 
06:16Shock absorbers.
06:19Suspension links, arms, and beams.
06:23This type of suspension has an arm control and  a shock absorber that performs an additional function of the suspension arm. 
06:31The anti-roll bar. 
06:35The subframe and bushings.
06:38The front part of the suspension system uses MacPherson struts, which are  very popular among car manufacturers. 
06:47On the rear axle, we can see a  semi-independent suspension with a torsion bar.
06:55Next. Car control systems. They include: 
06:59The steering system. The braking system.
07:04In this section, it would also be appropriate  to review engine and transmission controls. 
07:15The steering system is required to change  the direction of the car’s movement. 
07:23The braking system is required  to slow down and stop the car,  
07:30as well as to keep it in place.
07:34Engine control is used to alter the engine torque.
07:38This is an obsolete model with  a mechanical throttle valve.
07:43Transmission control is required  to temporarily disconnect the  
07:46engine and the transmission and select the  desired gear or the desired gearbox mode. 
07:55Passing on to electrical equipment. 
07:57Modern vehicles are inconceivable  without electrical equipment. 
08:02It stores, generates, transmits,  and consumes electricity. 
08:06All electrical equipment within a vehicle  can be classified into a few categories: 
08:11Power sources Power consumers
08:15Electrical wiring Auxiliary elements 
08:21Power sources are the battery and the generator. 
08:29Power consumers include various appliances  that require electricity to operate, 
08:34such as headlights, the starter motor,  the engine control unit, and others. 
08:41Electrical wiring connects various  components of the electrical system. 
08:46Auxiliary elements include relay and fuse  boxes, as well as various buttons and switches. 
08:54This concludes our review  of the basic car components.
