Directions for using of ZDZ Model Engines.
(Please read this carefuly before using the engine)
How to break-in the engine
如何進行引擎磨合
1. First three hours is neccessary to use fuel mixture 1:40 with full synthetic two stroke oil (more oil than for normal run)
前3小時是需要用高混合比的燃油，比例是1:40 全合成二行程機油(比正常時濃的混合比)。
2. Do not run the engine in maximum power during this period.
在這節骨眼上千萬不要讓引擎在全速下運轉
3. Max RPM in this period must be below 4000RPM
最高轉速不要超過4000轉
4. After this you can change the mixture to 1:50 and run the engine normally.
經過引擎合後(三小時高油比低轉速)才把混合比改成1:50 (1公升+20CC)
IF YOU WILL NOT FOLLOW THESE INSTRUCTIONS ENGINE CAN BE DAMAGED.
如果你沒照上列步驟進行磨何的話會造成引擎故障
ZDZ two-stroke gasoline engines are intended for large models and offer excellent power to weight ratios. Before being shipped from the factory, each ZDZ engine is tested and adjusted. As a result, there is rarely need for the user to make much in the way of adjustments. In general, they require only some minor carburetor adjustments that take into consideration the propellers and mufflers being used.
ZDZ 二衝程汽油引擎設計給大模型飛機提供優秀動力。在出廠前, 每個ZDZ 引擎都被測試和調整。很少需要用戶做調整。總之, 他們要求唯一考慮螺旋槳和消音器的更換做一些小化油器調整。
FUEL
We recommend the use of a good quality super (93-Octane) gasoline and a synthetic oil (specifically formulated for high performance two stroke engines) in 50:1 ratio. Make sure that the mixture is filtered before use.
我們推薦對優良品質 (93 辛烷值) 無鉛汽油和合成潤滑油混合(請使用給高性能二衝程引擎的二衝機油) 在50:1 比率。
BASIC SPECIFICATION
All ZDZ engines are equipped with diaphragm carburetors made by BING or Walbro. (These carburetors are adjusted with two mixture screws that are marked with the letter "H" (for the adjustment of High speed) and by the letter "L" (for the adjustment of idle and the acceleration from idle to full throttle). Basic adjustment - Both mixture adjustment screws are opened 540 degrees (1.5 turns) from the fully closed (stop) position.)
所有ZDZ 引擎都裝備BING 或Walbro 產的膜片化油器。(這些化油器被調整與由標記"L" 標記"H" 的二個油汽混合油針(H為高速的調整) 並且(L為怠速和加速度的調整) 。基本的起始調整點- 兩個調節螺絲被打開540 度(1.5 圈) 從充分地鎖死(中止) 位置退出。
ZDZ engines are equipped with commonly sized ball bearings. The piston con rod is equipped with SKF needle bearings. All ZDZ engines are equipped with BRISK UR 17 spark plugs.
ZDZ 引擎前後軸承為同大小的滾珠軸承。活塞連桿配備SKF 滾針軸承。所有ZDZ 引擎都配備BRISK UR 17 火星塞。
ADJUSTMENT OF THE ENGINE
After fitting the engine into the model and after installation of the ignition, you can start the engine. (Note: Installation of the ignition must be in accordance with the manufacturer's directions.)
引擎及點火系統裝上模型以後, 您就能發動引擎。(註: 點火系統必須是與製造商的說明書連接。)
1. Switch on the ignition, close the choke and suck gas into the intake of the carburetor by flipping the propeller over counter-clockwise. As soon as the engine is wet, it should start to run, but will stop due to the rich mixture. Next, open the choke and start the engine again by flipping as before.
1. 打開點火系統電源, 關閉阻氣閥逆時針撥動螺旋槳讓油進入化油器。當油汽進入引擎, 它應該會有爆發聲, 但會因富油停止。 打開阻風門再次發動引擎。
Note: The time it takes to draw gas into the carburetor depends on the length of the fuel feed to the carburetor.
注:油進入化油器的時間取決於燃料管的長度來決定。
Safety Notes: In the event that you adjust the engine in your model, be sure to switch on the receiver and the transmitter before starting it. It is best if the transmitter is set to "idle". WARNING: IF THE THROTTLE IS SET TO ANY SPEED ABOVE AN IDLE, THE MODEL MAY MOVE IMMEDIATELY THE ENGINE IS STARTED. AT ALL TIMES, SECURE THE MODEL AND/OR HAVE A HELPER HOLD THE MODEL SECURELY WHILE STARTING THE ENGINE.
安全註記: 如果您要在您的飛機上調整引擎, 請確定接收器和發射機電源已經打開。而且確定油門在"怠速" 。警告: 如果油門在怠速以上的任一位置, 模型也許會因引擎運轉而立刻移動。請安排幫手抓著模型才發動引擎以策安全。
2. Let the engine run for about 30 seconds on idle to allow it to warm up and then advance the throttle slowly.
2. 讓引擎怠速跑大約30 秒讓它慢慢地溫俥後才慢慢”吹油”加速。
3. Keeping well away from the propeller, adjust the engine to maximum rpm with the mixture adjustment screw marked with an "H".
3. 跟螺旋槳保持距離, 推油門全開. 轉進標記"H"螺絲求取最高轉速 。
4. Reduce the throttle and set the idle mixture with the mixture adjustment screw marked "L". Then use the same screw to adjust for a smooth transition from idle to full throttle. A well-adjusted engine will have a stable idle and will not surge up and down after the throttle is closed. If it accelerates slightly when the throttle is closed, the engine is lean. Open the mixture screw "L" a little and check the idle again. On the other hand, if it slows down after the throttle is closed, the engine is rich. In this case, close the mixture screw a little and check the idle again.
4.收油門調整標記的"L" 低速油針。然後使用低速油針調整從怠速到全速引擎都能平順運轉。一個完美的調整引擎將有穩定的怠速, 收油門轉速會上上下下都是不正確的。如果它輕微地加速, 引擎是稀油的。退低速油針 "L" 少許和再檢查怠速。另一方面, 如果它轉速慢慢降低, 引擎是富油的。在這種情況下, 進低速油針少許和再檢查怠速。
Note: If you change propeller diameter and/or pitch, the engine will have to re-adjusted.
注: 如果您改變螺旋槳尺寸, 引擎高低速油針將必須重調。
Note: To reduce noise, install an engine intake filter and use a suitable expansion muffler.
注: 為減少噪聲, 請安裝進汽過濾器和適當的消音器。
ZDZ MODELMOTOR s.r.o. guarantees its engines for a period of 30 months, provided any damage is not caused by tampering with the engine, by the use of unsuitable fuels or by the crash of a model.
保證它的引擎30 個月的期間, 人為故障. 不當使用燃料或者墜機或修改引擎, 不在保固範圍內。
