Hi, how does a car engine work?
user
The engine has several parts that work together to get a vehicle moving, such as the engine, transmission, engine controls, steering, tires, wheels, and fuel.
assistant
I'm most interested in knowing what is inside a car motor.
user
Inside a car motor, there is a rotating set of coils called the rotor. The rotor is located within the engine casing and is often referred to as the "rotor". In a car engine, the rotor is driven by the engine's internal combustion (IC) process. The rotor consists of a rotor core and a number of magnetic poles. Rotors also have windings which are a series of coils used to connect to the electrical system. The windings are installed in slots that allow the windings to move, causing the rotor to turn. The rotor is attached to the engine block by a large set of bolts or studs called studs or clamping bolts.
assistant
What does a head gasket inside a car motor do?
user
A car motor has an engine block that contains a combustion chamber and cylinder head assembly. The head gasket separates the combustion chamber from the cylinder head, but does not function as a seal. Inside the combustion chamber, the mixture of air and fuel ignites, driving the pistons up and down, while the engine block rotates. The rotating engine block turns the rotor and causes the alternator to produce electricity. The alternator, in turn, charges the battery.
assistant
Why do different car motors have a different number of cylinders?
user
A car motor has an engine block that contains a combustion chamber and cylinder head assembly. The number of cylinders in an engine depends on the size of the engine, and the design of the engine. For example, an engine with four cylinders is common in automobiles, but an engine with eight cylinders is common in trucks.
assistant
Why do trucks have more cylinders in the motor than cars?
user
Trucks have a larger engine and larger diameter tires, so they need to be able to provide more power.
assistant
Is horsepower of a car higher if there are more cylinders?
user
The answer to this question is a bit complicated.  Horsepower is a unit of measure for work performed in one hour.  Horsepower has a formula that includes two components: torque and rpm.  A truck has higher torque and a higher rpm than a car, so it will have a higher horsepower.  It’s also possible to have a high horsepower with a small motor.
assistant
What is torque in a car motor?
user
The torque (T) of a motor is a measure of the tendency to rotate a mass at a particular speed. It’s measured in Newton meters or kg-m/s. It’s also calculated by the equation T = (force) x (distance), where the force (F) is the mass of the object times its acceleration (a).
assistant
Can torque be affected if you have not had an oil change in a long time?
user
Yes, a car motor with a lot of accumulated dirt or oil can lose torque. It can also have more torque if you replace the oil in the engine with a good quality synthetic oil.
assistant
Why does it matter if you get synthetic oil rather than conventional oil in your car?
user
Conventional oils contain some synthetic additives, so many people think that oil is synthetic.  A synthetic oil is, in fact, a different type of oil.  The major reason for using a synthetic oil is to protect engine parts from wear.  Synthetic oils are better able to protect engine parts, including the engine block and cylinder head.

assistant

user
Synthetic oil is a better lubricant for an engine, because it is more resistant to combustion, meaning it is not as likely to smoke and/or start a fire. Synthetic oil also resists gunk from your engine, and does not form sludge like other oils can do.  It also protects against rust, acid rain, sludge, and even biological contaminants like bacteria.
