各位福特车友，
本人开ford focus 几年了，最近仔细看说明书时，才发现下面的字。

Warming up a vehicle on cold mornings is not required and deteriorates fuel economy。。

那么冬天的早上就不要先热车了？如果是这样，当然好，可以省油省时间。孩子的尿布钱可以省出来了。但是这好像和我以前知道的常识有悖。很困惑。

请各位高手相告！不胜感激之至。

原地热车没必要，只是浪费汽油。但冬天的时候尽量不要启动之后马上上高速公路，最好能在LOCAL低速行驶一段，其效果与以前的所谓的“热车”是一样的，效率更高。

Old habits die hard, and one of the oldest — still rigorously enforced by many drivers — is that "warming up" the car for a few minutes is necessary to avoid some kind of unspecified damage.

But idling is totally unnecessary, which is why many communities have enacted ordinances against the practice.

Don't take my word about idling being ineffective, but do listen to my mechanic, Rob Maier, who runs Maier's Garage in Bridgeport, Connecticut.

He says, "You don't really need to idle your car, because of the efficiency of modern fuel injection, which eliminated carburetors and chokes. The only reason to let the car idle at all is to get the oil circulating, but after 30 seconds that's a done deal. My truck has 150,000 miles on it, and I just throw it into gear and go."

Here are some quick facts and tips that should put the idling question to rest:



1. Driving warms the car faster than idling
If your concern is not the health of the car, but simply your own creature comforts, Bob Aldrich of the California Energy Commission points out that "idling is not actually an effective way to warm up a car — it warms up faster if you just drive it."

The coming electric cars, such as the Nissan Leaf, will incorporate a wonderful feature that allows the owner to use a cellphone to tell the car (which is plugged into the grid) to pre-warm or pre-cool the interior. No idling necessary.



2. Ten seconds is all you need
Environmental Defense Fund, which produced the Idling Gets You Nowhere campaign, advises motorists to turn off their ignition if they're sitting stopped for more than 10 seconds.

"After about 10 seconds, you waste more money running the engine than restarting it, said Andy Darrell, deputy director of the EDF Energy Program. "Switch the car off at the curb, and you'll be leaving money in your wallet and protecting the air in your community."



3. Idling hurts the car
According to the Hinkle Charitable Foundation's Anti-Idling Primer, idling forces an engine "to operate in a very inefficient and gasoline-rich mode that, over time, can degrade the engine's performance and reduce mileage."

The Campaign for an Idle-Free New York City points out that idling causes carbon residues to build up inside the engine, which reduces its efficiency.

4. Idling costs money
Over a year of five minutes of daily idling (which causes incomplete combustion of fuel), the "Anti-Idling Primer" estimates that the operator of a V8-engine car will waste 20 gallons of gasoline, which not only produces 440 pounds of carbon dioxide but costs at least $60.



5. Idling in the garage can kill you
Idling a car in a garage, even with the door open, is dangerous and exposes the driver to carbon monoxide and other noxious gases. If the garage is attached, those fumes can also enter the house.

6. Block heaters beat remote starters
Lori Strothard of the Waterloo Citizens Vehicle Idling Reduction Task Force in Canada says, "Remote starters can too easily cause people to warm up their cars for 5 to 15 minutes, which is generally unnecessary."

A block heater, which is designed to heat the engine and can cost under $30, on a timer set to start one to two hours before driving, does the trick in very cold climates.



7. Quick errands aren't quick enough
Natural Resources Canada points out that leaving your car idling while you're running into a store on an errand or going back into the house to pick up a forgotten item is another way to waste gas and pollute both your town and the planet.

"Leaving your engine running is hard on your pocketbook, produces greenhouse gas emissions, and is an invitation to car thieves," the agency (PDF) says.



8. Idling is bad for your health (and your neighbor's health)
According to Minneapolis' anti-idling ordinance, "Exhaust is hazardous to human health, especially children's; studies have linked air pollution to increased rates of cancer, heart and lung disease, asthma and allergies."

Isabelle Silverman, who runs EDF's anti-idling campaign, says that car idling "is the second-hand smoking of the outdoors. One of the problems is that cars idle close to the curb, where pedestrians are walking. And when you have a child in a stroller, they are particularly close to the tailpipe. Studies show that children's IQ levels are lower when they live near major roads with lots of traffic." (A fresh study even links autism to freeway pollution.)

Alex Scaperotta, who created an anti-idling campaign with a classmate when he was in fifth grade in Wilton, Connecticut, came up with a slogan that was used on bumper stickers and websites: "If you're stopped for more than 10, turn it off and on again." Sounds like good advice.

难道你没看到底下的留言有很多反驳他的马:rolleyes:

多谢各位朋友的建议，我现在打算冬天热个十秒钟就开了，当然，我不用马上上高速。如果马上上高速的话，我觉得还是热个几分钟较好，主要是感觉ford focus 冷车时加油门时不太给劲，所以在进入高速时加速慢怕会有危险。 当然我想这和ford focus 发动机只是2.0 的 有很大关系。

其实不用热车，不仅是省了油钱和时间。另外还可免装 remote starter. 我以为 remote starter的主要作用就是冬天可以提前热车。既然不用热车了，就可不装了。 在ford dealer 处，装一个含税要约500刀，简直是抢钱，好了，不用装了，省下的钱，可以给孩子报个夏令营了。

再次多谢各位的帮助！为我省下了尿布钱和夏令营的钱。还保护了环境。

如果没有 BLOCK HEATER，不怠速预热就吹不出暖风。风挡玻璃吹不开，如何上路？
