With the increase of population and the frequent economic activities, motor vehicles face the enormous challenge. The economical growth and the transportation have the inseparable relations in an observation of past history. Therefore, life cycle management on Vehicle Fleet has become more important than before.

Nowadays, the truck’s exhaust emission causes the air pollution which is a good example. As this reason, air pollution has threatened with human and environment sustainability. The main reason is that lacks of the effective maintenance; Because of this, the whole problems deteriorate rapidly. Therefore, Life cycle management knowledge should be tightened utilization into asset management.

This essay will discuss about truck. There are three parts including Tuck’s Description, Truck likely Issues and maintenance of Truck in the list below.

Truck Description
There are there parts of Truck Description inside the chart.

Chart 1: Outline of Truck Description

c Types
There are five types of truck including Mini Trucks, Light Trucks, Medium Trucks and Heavy Trucks.

c Basic Anatomy
There are several main portions of truck (2009) includes Cab, Engine, Drivetrain Frame, Tail-Lifts and Tail-Lift control.

A cab (picture 6) is a control space while driving; an enclosed space for diver to seat and rest while not driving.

An engine (picture 7) is a mechanical device which is the automobile power origin.

A drivetrain (picture8) is the most important system in a vehicle is which function is power transmitter from the engine to the wheels to make wheels work.

According to Wikipedia, “A truck frame (picture 9) consists of two parallel boxed (tubular) or C-shaped rails, or beams, held together by cross members. These frames are referred to as ladder frames to their resemblance to a ladder if tipped on end”.

Tail-Lift (picture 10) is an important device of a tuck which move goods from ground level to the load bed of truck level.

Tail-Lift control (picture10) is an important controller of a truck which controls tail-lift movement including up, down, left, right and stop.

c Performances
Truck function is for supporting companies or individuals to carry goods, products or materials form departure to final destination.





















Likely issues
Many companies confuse with many likely issues. In order to solve these problems, many companies pay more effort on analyzing truck issues. There are eight main likely issues of truck inside the chart.

Chart 2: Outline of Truck Likely Issues

Engine Cannot Work
The most likely issue of truck is engine cannot work which is caused by battery rustiness and battery damage.

Noise Increase
The second likely issue is noise increase. The reason for noise increase is engine’s exhaust system damage. Engine’s exhaust oxidation after the high temperature results in exhaust system leakage.

c Petrol Consumption Increase
One of likely issues is petrol consumption increase. Wheel pressure shortage is cause wheel work of obstructions. When wheel work of obstructions is an increase, then petrol consumption will increase.

c Engine performance reduction
Another likely issue is engine performance reduction. Oil, oil filter and air filter do not exchange are the three factors lead to engineer performance reduction.

c Petrol Pump Damage
Petrol pump damage is a likely issue as well. The main cause of petrol pump damage is the incorrect action of refueling.

c Battery instability
Another issue is battery instability. Battery acid appeals an abnormal change, battery will be instable.

c Wheel Damage
Wheel damage is another most likely issue of truck. Wheel damage includes ageing, normal or abnormal abrasion, something stick into a wheel, wheel moving is unbalanced, wheel alignment issue and so on.

c Exhaust Emission
Exhaust Emission is the more likely issue which do not only harm the environment but also threaten with human and animal survival. The cause of exhaust emission is incomplete combustion of engine system.

















Maintenance of Truck
Maintenance of truck is quite important. There are three sections of truck inside the chart. In order to maintain truck performance, truck should be maintained on a regulation time schedule.

Chart 3: Outline of Truck Maintenance

c Maintenance Items and Frequency
In order to maintain truck performance, truck should be inspected on a regulation time schedule. There are eight sections of truck maintenance including engine system, drive line system, brake system, wheel rim, tire, electric system, steering system, suspension system and other system. The part explains that how often and how many maintenance items companies should maintain on truck.

Maintenance Result Record List
Date Truck name Truck Type Truck Code Item Result Maintenance Man Remark
















Chart 6: Maintenance Result Record List

To sum up, there are many maintaining issues to exist at a great deal of vehicles in the world. For this reason, a good vehicle owner should have several life cycle management conditions to maintain these problems. Final recommendation attained from this discussion is for manager of automobile to achieve positive management.
