Interpretation of driving master of fuel-efficient misunderstanding

Neutral slide the fuel economy of this argument, accepted by many owners. Neutral slide is in neutral gear and slide the case of sliding downhill surface or deceleration. Many people think that this is a more fuel-efficient, in fact, it is not. Master Li said: "neutral gear driving in violation of the traffic ban hand, cost of oil for EFI engine car." Most of the EFI engine control system has to slow down to less oil or off the functionality of the oil, such a car high-speed with a sliding block can rely on its own design, the effect of fuel-efficient, if for neutral slide, this design would not achieve its proper role, in fact, but more expensive oil. "Hanging neutral fuel-efficient practices actually many years ago engine EFI technology is not yet widely used concept of the times, the engine fuel injection technology has been widely used, so no need to through the neutral gear and slide to fuel-efficient, according to the normal Guadang driving can be. "

The right approach: while driving, while warm car, as long as the speed is not too fast, open twelve kilometers, the engine will be able to reach operating temperature

Now there are many people like long hot car. Master Li said that once he was in the underground parking and other parking spaces, just met someone start the car, the result has been waiting a few minutes who the owners are still hot car half a day did not go. Master Li said that this approach is wrong, and parking hot car for too long, a considerable fuel, and it makes the engine short-lived. If one day warm the car is idling five minutes a year to one hour more than eighty minutes, then have to spend a lot of oil. Temperature idling car, over time, the cylinder wall of the engine room will have drops of water, the lubricating effect of attenuation of the water makes the oil, the engine car dvd and car gps will be easily damaged.

Master Li said: "The car now no longer use carburetors do not have to like before cold to pull the choke to warm the car, the correct way while driving, the side of the warm car, as long as the speed is not too fast, open twelve km, the engine will be able to reach operating temperature. "according to a Statistics show that: part of the wear and tear of engine parts, the proportion of over 90 per cent within three minutes after the cold-crank caused. The normal hot car time to control less than 1 minute.

The right approach: consider the residence time. If more than one minute you can turn off, if a relatively short time, is completely unnecessary. Car flameout certainly fuel-efficient, but also there is another problem: the fuel consumption of the engine each time you start an instant, and usually more than about 20% of the normal working condition, fuel-efficient or fuel can not be generalized. Master Li said: "Some owners like to turn off waiting for in parking and other traffic lights may want to consider the residence time if the parking time is greater than one minute you can turn off if the parking time is relatively short, no need to turn off." Engine as the car heart, turn off too much, start potential will reduce its life.
