Unit 9 Emission Control
Dialog 1
Bob and Mr. White are talking about the auto emission pollution.
Bob: Uncle, I read an article in China Economic Times about environmental pollution
caused by exhaust emissions.
Mr. White: Oh, what a coincidence. We just talked about that yesterday.
Bob: Yes. The article said that urban air pollution would shift from the current
combination of coal smoke and auto exhaust to mainly auto exhaust.
Mr. White: That is mainly because of the rapid increase use of vehicles.
Bob: Yes, it is.
Mr. White: Besides, many of the obsolete autos have entered the market and continue to
run on the road.
Bob: Do you mean that the obsolete vehicles cause more exhaust emission
pollution?
Mr. White: Yes. I think the strict supervision should be made in the management of
obsolete vehicles.
Bob: And I think we should also try to master advanced technologies to solve the
pollution.
Mr. White: That's for sure. There is a huge gap between the technologies of emission
control in China and those of the developed countries.
Bob: In addition, if fewer cars run on the road every day, there will be less
pollution.
Mr. White: I agree with you. If more people use public transportation, pollution caused by
exhaust emission will be less.
Bob: In that case, ! think I needn't to learn to drive a car. And maybe I should tell
more people to use public transportation to lighten the pollution problem.
Mr. White: Good idea.
Dialog 2
Black is asking the chief inspector, Stanley, to inspect the finished work.
Black: Excuse me, Stanley. What are you busy with now?
Stanley: Oh, I'm writing an inspection report for Mr. Li's Car.
Black: I'm sorry to interrupt you, but would you please take your time to inspect Ms
Wang's car?
Stanley: No problem. That's what I should do.
Black: Well, this is the key and. Please inspect it carefully, you see, she's our new
customer.
Stanley: All right. But I need the auto mechanic to check with me together. Who is
him?
Black: Oh, It's Jim. I'11' call him for you. Wait for a moment.
(After a few minutes)
Jim: Hey, Stanley. I'm here.
Stanley: Hello, Jim. I need you to help me with the inspection work.
Jim: Oh, come on, Stanley. Don't say in that way. We have been working together
for a so long time.
Stanley: Yes, you're right. And I know the work you do is always satisfactory.
Jim: Thank you. But the final in. spection is your job, I'm glad to help.
Stanley: So let's begin now.

Pre-reading
( 1 ) What is the function of the emission control system?
(2) What is the difference between the exhaust system and the emission control
system?
( 3 ) How to test the power of an engine?
Because emission control systems (Fig. 9-1) are designed to limit the pollution
caused by the harmful products of storing and burning fuel, the need to control the
emissions from automobiles has given rise to the
computeriza- tion of the automobile. Hydrocarbons,
carbon monoxide and oxides of nitrogen are created
during the combustion process and are emitted into
the atmosphere from the tail pipe. The crankcase and
exhaust system emit pollutants directly from the
engine into the atmosphere, that is, there are also
hydrocarbons emitted as a result of vaporization of
gasoline and from the crankcase of the automobile.
Emissions frown a gasoline driven motor vehicle
usually come from 4 sources: the fuel tank, fuel injection system, the crankcase, and the
exhaust system. In addition, the fuel tank allows fuel to evaporate and escape to the
atmosphere. These are called evaporative emissions.
The emission control system is an integral part of the engine, and should not be
tampered with or disconnected. This is especially true on vehicles with computerized
engine controls and/or those that must be subjected to mandatory emissions testing. Each
time the engine is started, the computer checks components such as the Oxygen sensor,
catalytic converter and other engine systems are functioning correctly. If a fault is
detected, the MIL is illuminated, indicating that the vehicle needs attention.
