The so-called run-in, the common misunderstanding is to run-in the engine, which is not comprehensive. The most critical aspects of running in a new car are actually two goals: the first is to achieve the combination of people and vehicles, and the second is the combination of various components in the car. Running-in follows two main lines, one is the power line: engine (power and lubrication system), transmission system (clutch and gearbox), follow-up and steering system (currently mainly power steering system). Another main line is the braking system: the brake oil circuit, the smooth contact between the brake disc and the disc, and the smooth contact between the brake drum and the brake shoe.
The following basic principles should be followed during the use of the vehicle during the running-in period, which is the basic requirement for the maintenance during the running-in period:
Load reduction: the loading capacity of the vehicle during the running-in period should not exceed 75% of rated load. Because overloading will increase the burden on the engine, transmission, transmission system, suspension system and other components, increase the wear and tear, and cause damage to the vehicle.
Choose high-quality lubricating oil: choose low-viscosity and high-quality lubricating oil, which can lubricate the friction surface well and slow down the wear of parts
Use oil reasonably. Generally speaking, gasoline engines should be When choosing SE grade, try to add gasoline of better quality (the gasoline grade is not necessarily very high, but it must be clean). In addition, try to choose a road with better quality to reduce the load on the body and power system.
The correct adjustment of the ignition system and oil supply system, and the correct adjustment of the ignition system and oil supply system, can solve the change of the vacuum fuel saver caused by the installation of the speed limiter, and improve the economy of the running-in period.
Because the bodies are still in the running-in period, excessive load and high speed will aggravate the impact on the parts, which will not only fail to reduce the roughness
, but also damage the parts. The damage caused by the parts, stepping on the accelerator for rapid acceleration, actually makes the engine work under an instantaneous heavy load. If the surface of the parts is not meshed well, it is easy to cause wear due to impact. If you drive at a certain speed for a long time, also try to avoid excessive and heavy loads.
