engines

Question 1

what is a V6 engine

Answer 1

a 6 cylinder piston engine where the cylinders share a common crankshift

Question 2

what is a V8 engine

Answer 2

a 8 cylinder piston engine where the cylinders share a common crankshift

Question 3

internal combustion engine (1800s)

Answer 3

a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit.

Question 4

electric/hybrid engines (mercedes-benz, bmw i3)

Answer 4

electric cars function by plugging into a charge point and taking electricity from the grid. They store the electricity in rechargeable batteries that power an electric motor, which turns the wheels.

Question 5

diesel engines (chevy cruze, bmw x5)

Answer 5

an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression

Question 6

cylinders

Answer 6

is the power unit of the engine. This is where fuel is burned and converted into mechanical energy that powers the vehicle.

Question 7

piston

Answer 7

is an essential part of the internal combustion engine which is key in converting the fuel which you use to fill up your car into energy to drive the car forward. It is a moving component which is used to transfer the force from the gas which expands in the cylinders to the crankshaft to turn the wheels.

Question 8

combustion chamber

Answer 8

It’s where fuel, air, pressure, and electricity come together to create the small explosion that moves the car’s pistons up and down, thus creating the power to move the vehicle.

Question 9

what is the combustion chamber made up of

Answer 9

The combustion chamber is made up of the cylinder, piston, and cylinder head.

Question 10

what are pistons made up of

Answer 10

Pistons are made from either a low carbon steels or aluminum alloys. The piston is subjected to high heat, inertia, vibration, and friction.

Question 11

what are cylinders made up of

Answer 11

The cylinder is made of metal and is sealed shut. It contains a piston that moves up and down, compressing the fuel, which ignites and causes combustion.

Question 12

mechanical compression

Answer 12

the increase of pressure in an engine cylinder as the piston travels toward the top dead center. Without a lubricant, the fuel can cause the valve seats and valve guides to burn away and you will lose compression and power.
