前回の教材の英語内容の一部を参考まで下記致します。もちろん、実際にはカラーの図解入り教材となっています。
Differential When a car turns a corner， the wheels on the outside of the bend must turn faster than those on the inside. This would be impossible if the engine turned one axle linked to both wheels. So the engine drives a differential – a set of gears that allows the power to be split between two half-shafts， each driving one wheel. Cams Cams are like oval wheels on which a rod called a cam-follower rests. As the cam rotates， it moves the cam-follower back and forth by a precise amount. Cams are often used for controlling or synchronizing processes， making sure that different actions take place at the right moment. Cranks When a wheel drives a crank， the rotation of the wheel is converted to a back-and-forth movement of the rod. With a rod drive， a crank converts back-and-forth movements into rotation. When the rod moves backward and forward， the crank wheel rotates. Four-Stroke Engine Four-stroke engine provides power for a car by burning fuel and air in a series of precisely timed explosions. The explosions inside the cylinders drive pistons downward. This movement turns a crankshaft which carries power to the transmission and to a camshaft. The camshaft synchronizes the opening of valves， so that each cylinder fires at just the right moment. (2009.06.01 11:38:09) |
