          長臂挖掘機直噴式和電噴式發動機的區別

          日期:2022-12-19   來源:http://www.thesonriseranchgallery.com/
          直噴式發動機和電噴式發動機是目前工程機械設備中常用的兩種發動機類型。我們了解長臂挖掘機的使用也需要了解其發動機的知識,所以下面長臂挖掘機出租廠家帶您了解一下長臂挖掘機直噴式和電噴式發動機的區別。
          Direct injection engine and electronic injection engine are two types of engines commonly used in construction machinery equipment. We also need to know the engine to understand the use of long arm excavators, so the following long arm excavator rental manufacturers will show you the difference between direct injection and electronic injection engines of long arm excavators.
          1、油門開度控制的不同
          1. Different throttle opening controls
          直噴式發動機是由轉速控制,是人手操控油門開度旋鈕和人工選擇動力模式開關來控制油門的開度,整體構造比較簡單。
          The direct injection engine is controlled by the speed. The throttle opening knob is manually operated and the power mode switch is manually selected to control the throttle opening. The overall structure is relatively simple.
          電噴式發動機由控制器檢測出以下信號:油門開度旋轉角度、動力模式開關、發動機轉速、油泵壓力轉速、各個操作閥的先導操控油閥、挖掘機的工作模式,以及水溫、油溫等信號。然后,電腦ECU按照駕駛員的操作想法,根據不同的動力模式和工作方式,負載情況和操作情況來確定一個較佳的油門開度位置。同時,電腦ECU還能控制油門開度的變化速率,讓發動機能發揮出較佳的性能。
          The controller of the EFI engine detects the following signals: throttle opening rotation angle, power mode switch, engine speed, oil pump pressure speed, pilot operated oil valve of each operating valve, working mode of the excavator, water temperature, oil temperature and other signals. Then, the computer ECU determines a better throttle opening position according to the driver's operation idea, different power modes and working modes, load conditions and operation conditions. At the same time, the computer ECU can also control the change rate of the throttle opening, so that the engine can play a better performance.

          2、噴油器開啟的不同
          2. Different fuel injector opening
          直噴式發動機工藝成熟,產品殘值率高(即直噴挖掘機用到結束時的價值),相對保值。
          The process of the direct injection engine is mature, and the residual value rate of the product is high (that is, the value of the direct injection excavator at the end of its use).
          電噴式柴油發動機是在高壓油泵、壓力傳感器、電腦控制單元(ECU)組成的封閉環境中,把噴射壓力的產生和噴射過程完全分開供油的。
          The electronic injection diesel engine supplies fuel completely separately from the injection pressure generation and injection process in a closed environment composed of a high-pressure fuel pump, a pressure sensor and a computer control unit (ECU).
          3、維修方面也不同
          3. Maintenance is also different
          從實際用戶體驗來看,直噴式柴油發動機的日常維修保養費用低,發動機工作時產生的扭矩較大,動力強勁。
          From the actual user experience, the daily maintenance cost of direct injection diesel engine is low, the torque generated by the engine during operation is large, and the power is strong.
          電噴式柴油發動機能夠做到和液壓系統良好的匹配。
          The electronic injection diesel engine can achieve a good match with the hydraulic system.
          4、方面的不同
          4. Differences in energy conservation and environmental protection
          直噴式發動機對油品的適應力強,但是燃油不能完全燃燒,用油量大,不。電噴式發動機對油品質量要求相對較高,燃油燃燒充分,節油。
          The direct injection engine has strong adaptability to oil products, but the fuel cannot be completely burned, the fuel consumption is large, and it is not environmentally friendly. EFI engines have relatively high requirements for oil quality, fuel burning is sufficient, fuel saving and environmental protection.
