Why do you want to idle for a day after the overhaul of the automobile engine?

After overhaul, it is recommended to idle the engine for one morning or one afternoon. During driving, you need to pay attention to running-in. The vehicle speed shall not exceed 100, running-in 1000 km. In addition, if idling running-in is prohibited in diesel engines, moderate throttle running-in should be adopted.

If the running-in is completed under no load or light load, the oil pressure at idle speed will be too low, and if there is insufficient lubrication, it may cause physical damage to the engine.

Running-in method of newly overhauled vehicles;

1. Cold running-in: The initial speed is generally 400 to 600 rpm, and the final speed is preferably 1000 rpm to 1200 rpm.

2. Determination of running-in load: generally, the starting load is (10-20)pep(pep is rated power), the running-in end load is generally (0.8-1.0)pep, and the gasoline engine is generally recommended to be (0.8- 1.0)pep.

3. Lubrication during running-in: Adding proper amount of active additives to lubricating oil can obviously improve the running-in process. Running-in time: the cold running-in time at each speed is about 15 minutes, ***60 minutes.

T-shaped brake: Put your feet in a T shape, with your right foot or left foot in front and the other foot behind, and keep your front legs slightly arched and your back legs pedaled. When using this method to brake, it is necessary to ensure that the shape of the foot remains unchanged during the braking process. Usually, you can slide with one foot during training, because before the T-shaped brake, you need to shift the center of gravity to the front foot and then lift the rear foot to make a T-shape. The front foot must be stable, and the rear foot should press the ice hard to increase friction.

2. Eight-character brake: Spread your feet, put your legs into an inner figure of eight, bend your legs and lower your center of gravity, and lean forward or backward slightly. It should be noted that the eight-character brake is suitable for use on gentle and long slopes. When using the eight-character brake, you should look straight ahead with your eyes. When braking, the legs of the eight-character brake will slide inward, and your legs should be supported outwards. Turning:

1. Parallel turning: If you want to turn to the right, you need to force your right foot, move your center of gravity to the right, relax your left foot and follow up in parallel, and when you turn to the left, you can reverse the action.

2. _ turn: You need to exert a little force on your knees to make the snowboard in a splayed state, and your body can roll.
