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.Where the entire cycle of events in the cylinder requires four strokes (or two crankshaft revolutions), the engines is called a four-stroke-cycle engine, or a four-cycle engine. The four piston strokes are intake, compression, power, and exhaust.1. What do we see from the paragraphs? ( )A. What is engine?B. What is stroke?C. What is cylinder?2.

Explain the working principle of a car's air conditioning system.答案：A car's air conditioning system works by compressing and then expanding refrigerant to absorb and release heat. The refrigerant absorbs heat from the cabin air when it is in the evaporator, cooling the air. When the refrigerant is compressed and flows through the condenser, it releases heat to the outside air, thus cooling the cabin.2. Describe the process of how a car engine converts fuelinto motion.答案：In a car engine, fuel is mixed with air in the intake manifold and then drawn into the combustion chamber. The spark plug ignites the fuel-air mixture, creating a small explosion that pushes the piston down. This motion is transferred to the crankshaft through the connecting rod, which then converts the linear motion of the piston into rotational motion. The rotational motion is transmitted to the transmission and eventually to the wheels, propelling the car forward.3. What。

The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine :gasoline(also calleda spark-ignition engine) and diesel(also called a compression-ignitionengine).Both engines are called heat engines; the burning fuelgenerates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to thetransmission.2.ESA(Electronic Spark Advance)systemThe ESA system monitors the engine condition through the signals, which are input to the engine and ECT ECU from each sensor(input signals from 1,3,11).The best ignition time is decided according to this data and the memorized data in the engine and ECT ECU and the control signal is output to TERMINAL IDT1,IGT2 and IGT3.
