Once it was considered good to keep the car engine idle a minute or two following cold stars. Today, with modern technology, the opposite is true. An engine operating under road conditions will warm up faster and run more efficiently than one that is idling. Idling just burns gas (on average, about a gallon an hour).
When you have a full tank of gas, park the ear facing downhill is possible, this will prevent any gas from coming out of the tank. Parking in areas of less or no sunlight helps prevent the gas from steaming that would occur if you parked in the hot sun. Your car will stay cooler, too, and that means less gas consuming work for the air conditioner once the engine is started.
Stay away from wide-track tires if you want top mileage (耗油1升行强多的英里里程). Narrow-track tires produce less friction and thus rolling resistance. The same effect is achieved by adding three to five pounds above recommended pressure to each tire; while this won’t noticeably affect your ear’s sliding quality, it will increase tire life and gas mileage.
Check tire pressure often, especially when the weather turns cold. The difference between winter and summer tire pressure can be as much as eight pounds. This could cost you two miles per gallon.
According to the passage, keeping the engine run idly ______.
选项
A、will just waste gas
B、will make it work more efficiently
C、will warm it up more quickly
D、is necessary in cold weather
答案
A
解析
根据关键词run idly定位到文章第一段最后一句:Idling just burns gas.该句指出,让发动机空 转只会费油,故答案选A。
