Caution engine preheating, regardless of whether or EFI diesel engine injection diesel engines are required preheating. Because the engine warm-up aims not only to make full combustion of fuel, antifreeze temperature rises, it also has a role in making the formation of a protective film of lubricating oil. 2, the engine warm-up time is not as long as possible. If a long hot car, then the diesel engine will do useful work, not only a waste of fuel and is not environmentally friendly. Diesel engines generally have started work before loading preheat 3-5 minutes is more appropriate. 3, under the cold state to avoid multiple startup and time to start. Diesel engine start times will increase the degree of wear of moving parts, reducing parts and engine life. According to authoritative studies have shown that more than 50% of engine wear is caused due to the cold start, because of wear caused by cold start is not reached due to the lubricating performance, so reducing the number of cold start will extend the life of the engine. 4, the engine warm-up time should check engine-related parts and operation is normal. In the engine warm-up time, you should check the dashboard lights are normal, you should listen to if there is abnormal sound engine, look in the engine smoke is normal. 5, see the tachometer determine whether the normal idle speed. Under normal circumstances, the machine hand just look at the tachometer is working to determine the machine warm-up is complete. Because the thermal expansion of the machine did not reach agreement, the auto governor considers the engine load is relatively large, the speed will naturally high, when the speed is normal, which means that the thermal expansion of the machine to reach consensus a used mini excavators prices, this time It can be identified machine to warm up has been completed. Taian Jia and Heavy Machinery Co., China's manufacturing underdeveloped. I studied mechanical manufacturing, talk about some of my experiences. When I factory chefs in order to make a precision CNC machine tools to improve regardless of White Nights and debug information in German translation, when I Exhausted and no holidays and overtime, covered with dirt mini excavator machine, full of hand is hurt, the operation failed numerous times but eventually manufacturing the first samples are expected accuracy of 0.0001 mm requirement, I am excited for a while, but then there has been a sense of loss, because that machining center CNC machine tools made in Germany, NC computer part is made in Germany, processing software or is German-made, even a turning tool, a drill, all made in Japan! In addition to plant a small excavator much money, not as tools are made in China! Even the plant also draws on the experience of foreign countries, fellow citizens, you're not out of this may not have a profound experience, I want to process an accuracy of 0.0001 mm parts, tools needed, that the above-mentioned foreign-made things, these tools high precision accuracy than the product several times or even several times a few times! A little bit for high precision machining, we just can not ah! Japan's better to buy a few thousand ah! I can not do anything ah.
