A: The first warm-up
Before starting the EFI mixer, the key should be transferred to the second gear and wait for 5 to 10 seconds before starting. Since the petrol pump started after the key door was opened, and the oil pressure and fuel injection amount were mediated, a few seconds later, the vehicle's mobilization machine had strengths.
After the start of the car, most people are accustomed to allowing the mobilization engine to run idly. When the water temperature reaches the normal temperature, the car is driven away. In fact, this method of preheating is often erroneous, because the escort machine is not mobilized by the carburetor. Machine, before reaching the temperature, the fuel supply system can not be normal, barely driving will naturally exhibit unstable speed, flameout and other phenomena, so carburetor mobilizer idle speed is a compelling step. The electrospray mobilization machine, if it takes a long time to warm up, is not only unnecessary but also harmful. Shortening the warm-up time can delay the service life of the three-way catalyst, and can also increase the conversion rate of pollutants in the exhaust gas and reduce fuel consumption.
Therefore, the correct approach is: After the start of the machine, as long as it can maintain the same speed can be started walking car, before the water temperature does not rise, the appropriate control of the speed, so normal water temperature can be normal driving. During the break-in period, stop the slam pedal and stop the brakes.
II: Do not drive at high speed
There are speed regulations for the initial stage of the new mixer. Domestic vehicles are generally specified within 40~70 km/h. The entrance vehicle is generally specified within the first 1,000 km. When the throttle is fully open, the vehicle speed is not higher than 80% of the maximum speed. And it is required to pay attention to investigating the tachometer and speedometer of the mobilization machine in use so that the speed and speed of the mobilization engine are all at medium speed. In general, the speed of the motor during the run-in period should be strictly specified between 2000 and 4000 rpm.
Three: To prevent overloading
The full operation of the new mixer will cause damage to the parts. Therefore, domestic cars cannot exceed 75% to 80% of the rated load within the first 1,000 kilometers; entrance cars cannot exceed 90% of the rated load. In addition, only the roads with good quality and good quality are selected to stop excessive vibration, collision or emergency braking, and eliminate the load on the body and power system.
Four: Bogey remove the speed limit film in advance
The speed limiting piece is a throttling device installed between the carburetor and the intake pipe. The driver shouldn't take it off in advance, but he should unite it in the maintenance environment after the initial 1,000 kilometers of accident and then remove it. The entrance car generally does not impose a speed limit, relying entirely on the mixer driver himself to control the speed.
Five: Avoid running remotely
Running the new mixer remotely will increase the duration of the engine's continued activities, causing increased wear and tear on the parts.
Sixth: Avoid pressing brake
Pressing brakes not only makes the braking system in running, but also increases the load on the chassis and the mobilizer. Therefore, do not reclaim the emergency braking within 300 km of the initial driving. What needs to be stated is that the practice of “taking off the brakes first†is a method of covering up the mobilization machine that was adopted during the very period of time and when it was in a state (immediate braking). Can not be used as a good habit for a long time, when the vehicle has gone through the run-in period, from the clutch maintenance aspect, it should be "first off the brakes," there are many novices in learning the car, because of fear of flameout, memory still pedaling, To decelerate, first step on the clutch, even if it is hung high or low gear, but also to facilitate the shift, the clutch does not leave the foot. This braking, shifting, to deal with novices will probably drive the car a little more smoothly, but it will cause no small damage to the clutch.
Some people are still accustomed to stopping the clutch and waiting for a stop when they are parked. They also hang a neutral gear and step on the clutch. They think that this can make walking and walking easier. However, this habit makes the left leg always in a state of exertion, unable to relax, and easily causing the driver to fatigue, and more serious will cause the clutch of the mixer to wear for a long time.
