1. 词义： ‘diesels’是指柴油机，是一种内燃机。柴油机是利用柴油燃料，在气体压缩的条件下发生自燃，用来产生能量的机器。
例句：
– Diesel engines are commonly used in trucks, buses, and boats.
– The company has developed a new line of diesel engines with improved fuel efficiency.
– Many people prefer diesel cars because of their high torque and better fuel economy.
– The ship’s diesel generator provides power when the main engines are not running.
– The mining company uses large diesel-powered machines to extract minerals from the earth.
2. 原理：柴油机工作原理与汽油机不同。柴油机利用高压把空气压缩到很高的温度，使得油气混合物自燃，产生动力。
例句：
– The diesel engine works by compressing air and then injecting fuel into the compressed air.
– The diesel cycle is more efficient than the otto cycle, which is used in gasoline engines.
– Diesel engines are able to produce more torque than gasoline engines because of their compression ignition system.
– The fuel injectors in a diesel engine deliver fuel directly into the combustion chamber at high pressure.
– The high compression ratio in diesel engines leads to better thermal efficiency and lower emissions.
3. 优点：相对于汽油发动机，柴油机有更高的燃油效率，更大的扭矩和更长的寿命。
例句：
– Diesel engines are more fuel-efficient than gasoline engines, which makes them a popular choice for commercial vehicles.
– The high torque of diesel engines makes them ideal for heavy-duty applications like towing and hauling.
– Many people prefer diesel engines because they tend to last longer than gasoline engines.
– Diesel vehicles emit less carbon dioxide than gasoline vehicles, which makes them a more environmentally friendly option.
– The use of biodiesel as a fuel source for diesel engines can help reduce dependence on fossil fuels.
4. 缺点：柴油机的缺点包括噪音大、震动大、排放污染高、需要更护等。
例句：
– Diesel engines are generally noisier than gasoline engines, which can be a drawback in certain applications.
– The vibrations produced by diesel engines can be uncomfortable for pengers, which is why they are less common in cars and SUVs.
– Diesel engines tend to produce more emissions than gasoline engines, which can contribute to air pollution.
– Diesel engines require more maintenance than gasoline engines, which can be a challenge for some owners.
– The initial cost of diesel engines is higher than gasoline engines, which can make them less accessible for some consumers.
