You’re alone, driving on a deserted stretch of highway. Suddenly you are enclosed by clouds of smoke and steam as the engine-temperature light flashes its red warning. You pull over to the slow lane and switch on the four-way emergency flashers. Then what? Should you keep on rolling or get off the road as fast as you can safely do so?
Knowing what is happening and what to do in a car emergency can save time, money, worry--even your life.
So learning how to check your car will help you handle some common car emergencies.
The engine’s bearings must constantly be lubricated (使润滑) by oil that circulates under pressure. When the oil pressure drops too low, the engine begins to self-destruct. The red oil-pressure warning light flashes on. Listen for any knocking, and sign of serious trouble. If the warning light flashes only at highway speeds and goes out at low speeds or while the engine idles, chances are’ the engine is just slightly low on oil. If the light goes on at idle, but goes out when you accelerate, drive slowly to the repair shop. It is a matter of minutes after oil pressure drops that serious engine damage occurs. You could destroy the engine.
The engine temperature warning light signals that the engine is running hotter than normal. Switching on your heater at the first sign of overheating may help delay a boilover--by drawing off some of the excess heat. Reducing speed may also help. If the light goes out, proceed to the nearest service station for help. If too much coolant has been lost, the engine will boil over, surrounding the engine with steam. If this happens, pull completely off the road, stop and wait. Don’t rush out and open the hood (发动机翼) in the steam. Wait until the vapor goes away and the engine metal cools. But remember that this can take a few hours on a hot summer day.
How do you know that the oil pressure is a bit low?
选项
A、The warning light flashes only when the car runs at fast speed.
B、The warning light flashes only when the car is slowing down.
C、The warning light flashes continuously.
D、The warning light flashes when the engine idles.
答案
A
解析
本题为细节辨析题。文中提到,当快速行驶时警示灯亮起,而当慢速行驶时警示灯熄灭,很可能意味着发动机只是有点缺润滑油。
