Where the entire cycle of events in the cylinder requires four strokes(or two
crankshaft revolutions), the engine is called a four-stroke-cycle engine.The four-stroke-cycle engine is also called the Otto cycle engine, in honor of the German engineer, Dr.Nikolaus Otto , who first applied the principle in 1876.The four piston strokes are intake, compreion, power and exhaust.Intake stroke.On the intake stroke, the intake valve has opened, the piston is moving downward, and a mixture of air and vaporized gasoline is entering the cylinder through the valve port.The mixture of air and vaporized gasoline is delivered to the cylinder by the fuel system and carburetor.Compreion stroke.After the piston reaches BDC, or the lower limit of its travel, it begins to move upward.As this happens, the intake valve closes.The exhaust valve is also closed, so that the cylinder is sealed.As the piston moves upward(pushed now by the revolving crankshaft and connecting rod), the air-fuel mixture is compreed.By the time the piston reaches TDC, the mixture has been compreed to as little as one-tenth of its original volume, or even le.When the air-fuel mixture is compreed, not only does the preure in the cylinder to up, but the temperature of the mixture also increases.Power stroke.As the piston reaches TDC on the compreion stroke, an electric spark is produced at the spark plug.The ignition system delivers a high-voltage surge of electricity to the spark plug to produce the spark.The spark ignites the air-fuel mixture.It now begins to bum very rapidly, and the cylinder preure increases to as much as 3~5MPa or even more.This terrific push against the piston forces it downward,and a power impulse is transmitted through the connecting rod to the crankpin on the crankshaft.The crankshaft is rotated as the piston is pushed down by the preure above it.Exhaust stroke.As the piston reaches BDC again, the exhaust valve opens.Now, as the piston moves up on the exhaust stroke, it forces the burned gases out of the cylinder through the exhaust-valve port.Then, when the piston reaches TDC, the exhaust valve closes and the intake valve opens.Now, a fresh charge of air-fuel mixture will be drawn in to the cylinder as the piston moves down again toward BDC.This four stroke cycle of piston within the cylinder is repeated time and again to put the vehicle forward.2.Notes The internal combustion engine, as its name indicates, burns fuel within the cylinders and converts the expanding force of the combustion into rotary force used to propel the vehicle.The actions taking place in the engine cylinder can be claified into four stages, or strokes.“Stroke” refers to piston movement;a stroke occurs when the piston moves from one limiting position to the other.The upper limit of piston movement is called TDC(top dead center).The lower limit of piston movement is called BDC(bottom dead center).A stroke is piston movement from TDC to BDC or from BDC to TDC.In other words, the piston completes a stroke each time it changes its direction of motion.6.作业及小结

The tappets serve to transmit the force from the camshaft to the push rods.The
tappets are small cylindrical bores receiving the push rods.They are made of cast iron or steel and located in the guides, which may be made integral with the cylinder block or removable as in the engine.When the engines operate, the tappets continuously rotate about their axes for uniform wear.The rotation is ensured by a convex surface of their bottoms and a slanted surface of the cams.2.cam design and control dynamic 3.camshaft drive mechanism 3.1 belt drive 3.2 chain drive 3.3 gear drive 4.electricvalve control system 5.Notes

1.Antifreeze
The purpose of the cooling system is to keep the engine at its most efficient
operating temperature at all speeds under all driving conditions.As fuel is burned in the engine, about one-third of the heat energy in the fuel is converted into power.Another third goes out through the exhaust pipe unused, and the remaining third must be handled by the cooling system.This means that the engine can work effectively only when the heat energy is equally handled so as to keep the engine temperature in balance There are generally two different types of cooling system: water-cooling system and air-cooling system.Water-cooling system is common.The cooling medium, or coolant, in them is either water or some low-freezing liquid, called antifreeze.A water-cooling system consists of the engine water jacket, thermostat, water pump, radiator, radiator cap, fan, fan drive belt and neceary hoses.2.Notes
The radiator is a device designed to diipate the heat which the coolant has absorb from the engine;it is constructed to hold a large amount of water in tubes or other paages which provide a large area in contact with the atmosphere.The radiator usually mainly consists of the radiator core, radiator bottom tank, and radiator top tank.Radiator cores are of two basic types, the fin and tube type(fins are placed around the tube to increase the area for radiating the heat)and of the ribbon cellular or honey comb type.3.作业及小结： 翻译：
The radiator cap serves not only to prevent the coolant from splashing out the filler opening, but also to prevent evaporation of the coolant.第11讲Unit 9 Fuel System

2.Gasoline is a complex blend of carbon and hydrogen compounds.Additives are then added to improve performance.All gasoline is basically the same, but no two blends are identical.The two most important features of gasoline are volatility and resistance to knock(octane).Volatility is a measurement of how easily the fuel vaporizes.If the gasoline does not vaporize completely, it will not burn properly(liquid fuel will not burn)
3.Diesel fuel, like gasoline is a complex blend of carbon and hydrogen compounds.It too requires additives for maximum performance.There are two grades of diesel fuel used in automobiles today: 1-D and 2-D.4.Tank location and design are always a compromise with available space.Most automobiles have a single tank located in the rear of the vehicle.Fuel tanks today have internal baffles to prevent the fuel from sloshing back and forth.Steel lines and flexible hoses carry the fuel from the tank to the engine.When servicing or replacing the steel lines, copper or aluminum must never be used.Steel lines must be replaced with steel.6.作业及小结

1.Engine Fuel System The fuel system is critical to operation.The system consists of the fuel tank, lines,pump, filter, carburetor, and injectors.2.Fuel Flow The fuel in the fuel tank is ready to be used when the engine needs it.The fuel pump draw fuel from the tank and sends it to the carburetor.The carburetor is to keep the fuel at the right air-fuel ratio.For a electric fuel-injected engine, the fuel is preurized and sent to the fuel feed pipe, through a fuel filter, and into the fuel injectors.3.Fuel Tank 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.4.Notes
The mechanical fuel pump is used on many vehicles with carburetors and driven by the camshaft.There is a cam or an eccentric lobe on the camshaft.As the camshaft turns, the lobe lifts a lever up and down, causing a pumping action.Fuel is drawn from the tank by a vacuum and sent to the carburetor.5.作业及小结：
翻译：Steel lines and flexible hoses carry the fuel from the tank to the engine.When servicing or replacing the steel lines, copper or aluminum must never be used.Steel lines must be replaced with steel.28
