2. The fuel tank is used to store the fuel of engine needed. It is usually located in
rear of the vehicle. The fuel tank is designed to fit around frame and to be protected
from impacts. These are several baffles insides the fuel tank to restrict fuel movement
during rapid starts and stops, cornering, and so on. The fuel cap on the fuel tank is
used to keep the fuel from splashing out, release the vacuum created by the fuel
removing, and prevent vapors from escaping directly into the atmosphere.
fuel levels are measured by a fuel-metering unit. One style of the unit has a
hinged float inside the tank. As the float position changes with different levels of fuel, the
needle position on the dashboard gauge changes.

the bellows-type electrical fuel pump, a metal bellows is used instead of a
diaphragm. It operates from the movement of the armature in the magnetic coil. The
3 8

bellows is stretched and squeezed to cause the vacuum and pressure.
2. The roller vane electrical fuel pumps are used on newer vehicles. As the electric
motor turns an impeller, fuel is drawn in at the inlet port of the pump. It is pressurized
and sent out the discharge port for delivery to the engine. The impeller at the inlet end
serves as a vapor separator. A pressure relief valve keeps fuel pump pressure at a constant
level.
3. Fuel systems that have electrical fuel pumps and fuel injectors may use a
fuel pressure regulator to keep the fuel pressure constant.

The gasoline engines may have one or two filters in the fuel system. The first filter
is usually placed inside the fuel tank to prevent large pieces of contaminant from
damaging the fuel pump. The second one is an in-line type or an in-carburetor type used
to filter out small dirt particles.
5.作业及小结:
翻译:
The flow of air and fuel through the carburetor is controlled with a throttle plate.
The throttle plate is placed below the venturi and connected to the acceleration pedal.
As the driver's foot on the pedal is depressed, the throttle plate opens, and there is
very little restriction of air and fuel. The load and speed is increased.

2. Automobile suspension system has two basic functions, to keep car's wheels
in firm contact with the road and to provide comfortable ride form the passengers.
A lot of the system's work is done by the spring. Under normal conditions, the springs
support the body of the car evenly by compressing and rebounding with every
up-and- down movement. This up-and-down movement, however, causes bouncing
and swaying after each bump and is very uncomfortable to the passenger. This
uncomfortable effects are reduced by the shock absorbers.
3. 作业及小结
Suspension, when discussing cars, refers to the use of the front and rear springs to
suspend a vehicle's
constructed in a variety of types, sizes. Types include leaf springs, coil springs, air
springs, and torsion bars. They may be paired off on vehicles in various combinations
and are attached to vehicles by several different mounting techniques.

1. Passive suspensions
The leaf springs most commonly used in automobiles is made up of several long
7 8

plates, or leaves. The leaf spring acts like a flexible. For example, if you tried to bend a
solid beam, the top edge would try to get longer while the bottom edge would try to push
together. The result is that the top edge of the beam might pull apart and the beam might
break.
2. suspension types
In the past, a wide variety of direct and indirect shock absorbing devices were used
to control spring action of passenger cars. Today, direct, double-acting hydraulic shock
absorbers and shock absorber struts have almost universal application.
3. Because the leaf spring consists of a series of thin leaves, one on top of another,
it does not break when bent. When the spring is bent, the individual leaves bend and
slip over one another. This provides a spring with great flexibility and strength.

In the rear- suspension systems of many cars, coil springs are used instead of leaf
springs. The coil spring is made from a length of steel road rod would into a coil. The coil
spring is very elastic and will compress when a weight is put on it. The heavier the
weight the more spring will compress.
5.作业及小结:
翻译:
A rear- suspension system uses coil springs. Each spring is assembled between
spring seats in the car frame or body and lower control arms, or pads, on the axle
housing. When the rear wheels hit a hole or a bump in the road, the springs expand
or compress to absorb the shock.
