Some owners heard vehicles now because the technology improves, hot cars this step can be omitted. Open out to go to work hurry often after the start of the overnight suspension of service on the vehicle. Almost all professionals the mentioned driving habits, that its only loss of the engine and expensive oil. En Rui automotive brake caliper engine after standing overnight, the friction surface residual lubricating oil pressure has long since disappeared, lost film protection, low-temperature viscosity of lubricants greatly increased, worse adhesion and liquidity. Therefore, not hot car engine wear is quite large. The same time, low temperature start the engine, then step on the gas grid, because the temperature is still low, gasoline atomization is not sufficient, you can not fully burning, easy to form coke, very cost oil.
Many owners no clear concept of how long the hot car. Some believe that the need for 3 to 5 minutes, and some think that 30 seconds is sufficient. The shop technicians also no consistent answer. More mainstream concept, the current models on the market, because of improvements in technology, compared with older vehicles hot car models can be shortened accordingly. The specific hot car time can refer to two indicators, one is the water temperature, an engine speed. In general, if in the process of idling hot car, first requires the engine speed to return to the normal idle speed level. Ashkenazi models are high speed, after its start until 1000 rpm or so before traveling, and also one of the idle state, the speed of about 800 or so, which are required to meet the conditions of the other models. Another condition is that the dashboard shows the water temperature changes can fuel door traveling. Some owners will probably wait until the water temperature rose to 70 to 80 degrees Celsius normal driving, can be considered a good choice.
For hot cars idling after a cold start, what situ hot car or idling amble hot car, is still controversial.
Technicians situ hot car and idling slow lane, all belong to the hot car. Situ hot car process should not be canceled, and its specific time should be at least about 30 seconds, so that the operation of the oil pump, the oil delivered to the engine most piston, connecting rod and the crankshaft and other components that require lubrication. Subsequently, the vehicle can be started. Just, just started a couple of hundred meters within a short distance, the owners should not throttle. The general operation that is in accordance with the mentioned above, such as water temperature and speed standards and then step on the throttle.
Seasonal maintenance of the cooling system
1. Should start with the appearance scuppers check the water pump, thermostat connector, up and down the water pipe joints, the bleeder, radiator caps and water storage tanks and other parts for any leaks traces. If you find a leak, you should find out why immediately excluded, do not make do with open.
To check the freezing point of antifreeze. Generally, antifreeze liquid freezing point than the vehicle below the minimum temperature in the region of 5 to 10 ℃ can. Such as: the Beijing area of the vehicle, the freezing point of the antifreeze in the minus 25 to minus 30 ° C will be able to ensure a safe winter.
3 Note antifreeze liquid level generally about 10 mm from the tank with water outlet is appropriate, or in accordance with the the replenishment tank on the standard scale of additional similar antifreeze, do not add antifreeze or water too full to to allow sufficient thermal expansion tank space.
4. Finally, check the thermostat. If the thermostat is not working properly, the engine is in a good state to work under low or high temperatures, will aggravate the wear and tear of the engine, shortening the life of the engine, so the thermostat must ensure long-term.
Automotive brake caliper Antileak reminder: the thermostat must not be removed. General models remove the thermostat about 2-30000 kilometers traveled, the engine will be scrapped. |
