Carbon Fiber Tubing Promotes Lightweight Vehicle

Under double pressures of sharp decrease in resources and pollution of the environment, new energy vehicles and automotive lightweight becomes the themes of The Times. Carbon fiber tubing as a new material, because of its light weight, high strength, high temperature resistant, corrosion resistance and other excellent new can be called "black gold". Its use, can effectively reduce weight, is one of the most ideal material to improve energy efficiency.
Carbon fiber tubing available time is not long, only original military-industrial complex and aerospace industry, along with the development of The Times, gradually in the civil system of automobile, medical equipment, machinery manufacturing, train high iron industry stand out. Its density is very small, only a quarter of the steel, tensile strength is more than four times higher than steel, improve the utilization ratio of fuel at the same time, the shock, impact performance, safe and reliable. Carbon fiber tubing main components for carbon, the characteristics of both soft and hard design of high degrees of freedom, integration, new, and can reduce the number of parts assembly costs a lot. A whole car, the frame structure, the tail, interiors and exteriors, hood, doors, roofs, instrument panel, side skirts, rear view mirror housing, license plate frame, most of the parts can use carbon fiber tubing, such as the cap manufacturing.
Abroad some premium car brands, such as BMW, Rolls-Royce, Mercedes-benz already use carbon fiber tubing manufacturing parts, some of the domestic car lovers also began to use the high quality material modified cars. Believe in the future time, carbon fiber car can be used widely.

Why is plastic bad for the environment?


Some of the harmful effects of plastics on our environment are :
1. Soil pollution-Plastic is a nonbiodegradable waste, it cannot be decomposed by the microorganisms present in the soil and hence cause soil pollution.
2. Air pollution- Burning of plastic materials releases many toxic and dangerous gasses like carbon monoxide, and cause extreme air pollution.
3. Dangerous for water organisms- Disposing plastics on water bodies can harm water living organisms. Also, they cover up the surface of the water and not allow sunlight and oxygen to enter on water which can cause ***** of many water organisms.
4. Water pollution- Plastic also cause water pollution as plastic materials cannot be decomposed by the microorganisms present in water.

Why would push and pedal vehicle toys be better than ones with electric motors or gas engines?


Push and pedal toys are much more environmentally friendly than those with engines and motors. They develop the child's imagination and motor skills and at the same time avoid polluting the environment or wasting energy. They also last much longer, especially the old fashioned metal versions.

what is the emission controlls evarorative system


Emission control systems have been incorporated into automobiles to prevent pollution by limiting the amount of partially burned and evaporated gases into the atmosphere. These systems have been efficient in reducing the pollution caused by automobiles to a large extent. Automobiles were first manufactured with exhaust emissions control systems in 1966. Since then technology has undergone several changes that has increased the number of cars which use this technology. The emission released is calculated by quantity released per distance traveled. The types of emissions are tailpipe emissions, life cycle emissions and evaporative fuel emissions.
Catalytic Converter
The catalytic converter was developed in the early 70's when severe air pollution was emanate, but wasn't made mandatory by the US government until 1976. The catalytic converter or "cat" for short is one of your vehicles main emission control devices. The name was derived from the operation the catalytic converter performs, it takes a catalyst and converts the unburned gases to burned gases, "catalytic converter".
EGR Valve
EGR valves are used is to lower KNOX (NO2) gases which occur when the combustion chamber when temperature reaches over 3,500 degrees Fahrenheit. KNOX gases have proven to cause brain damage and have been mandatory on most vehicles since 1976. An EGR (exhaust gas re-circulation) this valve controls exhaust gases to enter the intake manifold and flow into the combustion chamber at certain times in the operation of the vehicle. To test your EGR valve remove the vacuum line that is connected to the valve, apply vacuum using a vacuum pump to the valve while the engine is running. If the engine stalls the EGR system is working, if not, the EGR valve may have failed.
Tailpipe emissions are released as bi-products of spent fuel that is combusted inside the cylinders of the engine. These omitted gases consist of carbon monoxide, hydrocarbons, carbon dioxide and nitrogen oxides. To control tailpipe emissions measures have been taken to increasing engine efficiency. This efficiency involves technologies such as lightweight vehicle design, regenerative braking, decreased rolling resistance, increased ignition voltage, minimizing air resistance and improving power train efficiency.


Lifecycle emissions are products which are released during the manufacturing, maintenance and disposal of the vehicle. The products include volatile solvents such as auto paint and lubricants, manufacturing plant power waste, oil filter and oil changes, heavy metals, tires, landfills, etc. These kinds of emissions are responsible for creating urban smog which consists of heavy molecular gases which pollute our environment.

Temperature change can result in the evaporation of fuel in the tank because of the development of pressure, this is known as gas tank venting. Recently fuel systems have been equipped with a closed system called EVAP, this allows the vapor to be stored in a charcoal canister until it can condense into a liquid and then returned to the fuel tank.

Another emission control system known as the air injection reactor or AIR, oxygen is injected in the exhaust manifold. This system decreases the bi-products of incomplete fuel consumption.


If the emission control system malfunctions the "check engine" light will illuminate. Scan the PCM for trouble codes, repair the problem, then clear codes to re-test system. Most automobile's have an emission system information label under the hood, or consult a repair manual.

The emission system performs regular test while the car is in use called a "test cycle". Tailpipe emission are measured in parts per million or PPM. Presently, the limit for evaporated gases is two grams of HC per hour, which is about one liter per month. At first, the idle test, which was a two-speed test was conducted in the 1980s. Then it was substituted by the dynamometer test in the late 90's, in the accelerated simulated mode or ASM three gases are tested. Various states and countries have developed unique laws about pollution testing of vehicles.

Good luck, and remember rated this help.
