Brakes
are actually energy conversion devices, which convert the kinetic energy
(momentum) of your vehicle into thermal energy (heat).
The
purpose of the engine's cooling system is to remove excess heat from the
engine, to keep the engine operating at its most efficient temperature,
and to get the engine up to the correct temperature as soon as possible
after starting.
The
drive train serves two functions: it transmits power from the engine to
the drive wheels, and it varies the amount of torque. "Power"
is the rate or speed at which work is performed. "Torque" is
turning or twisting force. Multiple ratio gearboxes are necessary
because the engine delivers its maximum power at certain speeds, or RPM
(Rotations Per Minute)
Today,
an automobile requires an elaborate electrical system of circuits just
to produce, store, and distribute all the electricity it requires simply
for everyday operation.
There
are several types of internal combustion engines: two and four cycle
reciprocating piston engines, gas turbines, free piston, and rotary
combustion engines.
Many
states require emissions tests on vehicles. This means that you drive to
a facility where the test people take a sample of your emissions and run
it through some analysis.
Major
parts of the system include: fuel tank and cap, emission controls, fuel
line, fuel pump, fuel filter, carburetor, and intake manifold as well as
the fuel gauge, which indicates the amount of fuel in the tank.
Not
only do we depend on our cars to get us where we want to go, we also
depend on them to get us there without discomfort.
Suspension,
when discussing cars, refers to the use of front and rear springs to
suspend a vehicle's "sprung" weight. The springs used on
today's cars and trucks are constructed in a variety of types, shapes,
sizes, rates, and capacities.
