1．發動機預熱與全自動加熱的差別？

What is the difference between engine preheating and fully automatic heating?

答:發動機預熱的前提條件是：冷卻液溫度小於10℃時，根據QOS控製板全自動開展預熱塞加溫。當鑰匙開關在ON時，加熱期為20秒，在其中加熱顯示燈照亮8秒。加熱結束後，鑰匙開關在START時，汽車發動機會繼續加熱30秒。

Answer: The prerequisite for engine preheating is that when the coolant temperature is less than 10 ℃, the preheating plug will be automatically heated according to the QOS control board. When the key switch is on, the heating period is 20 seconds, and the heating display light illuminates for 8 seconds. After the heating is completed, when the key switch is in START, the car engine will continue to heat for 30 seconds.

全自動加熱的前提條件是：當齒輪油小於0℃時，啟動汽車發動機，液壓機油溫傳感器將電子信號傳到MC,MC推動EC電機，以總體目標轉速比1250rpm運行，運轉時間為15分鍾左右或齒輪油溫升到2℃左右時，全自動加熱。

The prerequisite for fully automatic heating is: when the gear oil temperature is less than 0 ℃, the car engine is started, and the hydraulic oil temperature sensor sends an electronic signal to the MC. The MC drives the EC motor to run at the overall target speed ratio of 1250rpm, with a running time of about 15 minutes or when the gear oil temperature rises to 2 ℃, the fully automatic heating is eliminated.

2．渦輪增壓與中冷器的功效？

2. What are the effects of turbocharging and intercoolers?

答：渦輪增壓的重要的作用是使柴油發動機在排氣量不變的前提下提升功率，改進點燃實際效果，提升機械能，減少燃油消耗率，提升混和實際效果，給予空然比，減低有害物質的排出，改進低速檔特性，達到汽車發動機在低速檔使高扭矩的特點。

Answer: The important role of turbocharging is to increase the power of diesel engines without changing the exhaust volume, improve the actual ignition effect, increase mechanical energy, reduce fuel consumption rate, improve the actual mixing effect, provide air to fuel ratio, reduce the emission of harmful substances, improve the low-speed characteristics, and achieve the characteristic of high torque for automotive engines in low-speed gears.

中冷器作用是因為渦輪增壓吸入空氣經壓縮環境溫度會提高，氣體在流通環節中與進氣管壁磨擦還會繼續進一步提溫，危害充氣效率，中冷器如同熱管散熱器，將氣體熱量根據它而散到空氣中去，快速降溫還可以提升氣體進氣口相對密度，進一步提高發動機有效功率。

The function of an intercooler is because the turbocharged intake air will increase the ambient temperature after compression, and the friction between the gas and the intake pipe wall during the circulation process will further increase the temperature, endangering the inflation efficiency. The intercooler is like a heat pipe radiator, which disperses the gas heat into the air according to it. Rapid cooling can also increase the relative density of the gas inlet, further improving the effective power of the engine.

3．履帶式張鬆緊度在各個工作狀況中的變化？

3. How does the tension of the track type change in various working conditions?

答：在平整紮實的地麵，履帶式應調節略緊；有多石高低不平的路麵，履帶式應調節略鬆；在綿軟的地麵，履帶式應調節略鬆。

Answer: On a flat and solid ground, the track type should be adjusted slightly tighter; On uneven roads with many stones, the track type should be adjusted slightly loosely; On soft ground, the track type should be adjusted slightly loosely.

4．設備在加減速或負載變化時，消聲器出現股股冒煙怎麽解釋？

4. How to explain the smoke emission from the muffler during acceleration, deceleration, or load changes of the equipment?

答：因為提升中冷器後，使進氣口通道拉長，進氣口摩擦阻力提升。當設備在加減速或負載變化時，汽車發動機調速電機調整汽柴油提供，進而破壞原先的空燃比，以於在一瞬間出現股股冒煙，此情況為正常情況。

Answer: Because lifting the intercooler elongates the safety channel at the air inlet and increases the frictional resistance at the air inlet. When the equipment undergoes acceleration, deceleration, or load changes, the automobiles engine speed control motor adjusts the supply of gasoline and diesel, thereby damaging the original air fuel ratio, resulting in a sudden smoke emission. This is a normal situation.

5．防止設備導致傾覆的一些常見問題？

5. Some common problems in preventing equipment from overturning?

答：嚴禁滿鏟時鬥杆全伸快速旋轉；軟基處理工作時需避免設備凹陷；防止設備吊載走動；防止設備爬斜坡時傾覆；防止上坡轉為時傾覆；托車運載時防止傾覆。

Answer: It is strictly prohibited to fully extend and quickly rotate the bucket handle when the shovel is full; Avoid equipment depression during soft foundation treatment work; Prevent equipment from being lifted or moved; Prevent equipment from overturning when climbing slopes; Prevent overturning when turning uphill; Prevent overturning when carrying on a scooter.
