Nowadays, there are more and more learner driving test drivers and more novices on the road. Most of the newcomers will still be in a dizzy situation when they encounter complicated roads. They do not turn their lights when turning and do not turn on lights when overtaking. Many accidents are also caused by novices. Today, DOCA car emergency start power Xiaobian take a look at the novice most likely to make mistakes.
Misunderstanding one: car second gear start
Car transmission design emphasis on speed. If reluctantly started with second gear will not only increase the load on the engine, but also lead to early wear and tear of the clutch, so the car no matter how much displacement should be a start.
Misunderstanding 2: plus overtaking
Drivers generally believe that high-grade bit faster, so in the overtaking on the way up a file. In fact, the progress of the vehicle must rely on the torque exerted by the engine. The torque in the high-grade position is small, the throttle is unresponsive and the acceleration is slowed down. Therefore, the correct overtaking should be slowed down. The automatic wave only needs to depress the accelerator and the transmission will Lower one gear to provide enough torque.
Misunderstanding three: turning brake at the same time
When turning the car center of gravity to the outside, then the brake will increase the roll, causing unilateral braking, if the speed is too fast, or brake too fast, there is a rollover risk. The correct approach should be reduced to speed before entering the corner into the low block, into the corner, the body slowly to maintain a stable posture.
Myth # 4: Backhand hit the steering wheel
In the old cars, heavy steering wheel, backhand steering wheel more effortless, and the new car is more dangerous to do so, the backhand hit the direction, if the wheels rolled to obstacles will suddenly rebound, the wrist will be seriously injured, so to develop good (Generally left hand put 9 or 10 o'clock position, the right hand to put 3 o'clock or 2 o'clock position, one hand on the push, the other hand on the pull down the way to turn the steering wheel), do not cross hands, backhand hit the steering wheel.
Myth: brake on the clutch first
Some people think that braking should be cut off before the power, the brake will be more effective, this is a serious mistake. Because depresses the clutch, the engine speed rapidly reduces to the idling speed, reduces the total vacuum of the intake manifold, reduces the auxiliary force of the vacuum booster greatly, but the braking distance instead lengthens. Correct operation, should be depressing the brake, when the speed drops to near stop, then depress the clutch.
Myth # 6: Downhill Neutral taxiing
Some owners are desperate for the convenience of the map, gliding on neutral, braking only to control the speed, which is certainly dangerous potential, if it is in a long-distance slope to do so, the brake system will suddenly fail due to overheating, Cause the accident. The correct approach is based on the actual speed hook up the right stalls, so that the engine brake, and occasionally supplemented with brakes, it is safe and extend the life of the brakes.
Myth: Vent can be fuel-efficient
Car carburetor car drain is fuel-efficient, but the EFI car is not necessarily fuel-efficient, because some cars release the accelerator in acceleration, the fuel injection system to stop the fuel supply, when the engine speed down to 2000 rpm to restore fuel supply, so EFI car with a high-speed taxi will be fuel-efficient, empty gear instead of oil.
Misunderstanding eight: run-in period, the slower the better
Run-in period is to a certain period of friction components with the gap to a reasonable range, in order to achieve better lubrication. If the run-in period engine speed is too low, the crankshaft connecting rod bush bearing greater impact, the cylinder speed is too high, easy to strain, resulting in early wear and tear, so the run-in period should be based on the engine speed rather than speed, gasoline engine speed in 2000- Between 3000 rpm, the diesel engine is between 1000-2000 rpm.
Mistakes nine: high-end small throttle more fuel-efficient
This practice is easy to detonate the engine, the fuel outbreak of the power can not do the work, and the impact of the connecting rod mechanism, resulting in early wear and tear, low torque in the lack of strength, acceleration weakness, but may increase fuel consumption may be the best section Oil and protect the engine in the area of the maximum torque speed is low may work to get the maximum power and the best fuel economy.
Misunderstanding ten: car starts preheating for 10 minutes
Preheating the car before starting, can make the mechanical parts get better lubrication, reduce friction and prolong service life. But the warm-up time should not be too long, can make the lubricating oil to reach the desired lubrication site, the general recommendations 5-8 seconds. Over time, will only result in fuel consumption and engine wear large. Auto-wave car, let the car from start-up speed down to about 800 turn more appropriate, of course, the veteran can hear from the sound.
Misunderstanding 11: Anti-wear agent can extend the life of oil
Antiwear agent, the better wear resistance, the weaker the oxidation resistance, the more the amount of oil instead of the more damage.
