DLE20 Gasoline Engine English Manual

Age Recommendation:RC engine is not a toy! Not for children under 14 years.
The engine is designed for use on a model radio control airplane. If it is used for any purpose, we cannot be responsible
for its reliability of safety.
·Keep away from the rotating propeller area while operating the engine.
·Do not wear loose clothing near the engine or the propeller.
·Do not operate the engine near loose material such as dirt, gravel, ropes, sand, etc.
·Always run your model engine in a well-ventilated area. Model engines produce possibly harmful carbon monoxide
fumes.
·Always ensure that the propeller is securely attached to the engine shaft and all retaining fasteners are tightened
properly before each flight.
·Always stand clear of and behind the propeller, ensure the face and body are far away from the propeller blade after
trajectory. Never allow anyone, to be in front of or to the sides of the propeller when starting or running the engine.
·Always ensure that small parts in the children can\'t touch place to prevent children from swallowing parts;
·Always check the propeller nut tightening.
·Gasoline is extremely flammable. Be careful of any sparks from electrical contacts such as fuel pumps, battery charger,
etc.
·Allow your engine stop and cool before touching or fueling. The running engine of the surface temperature is high,
easy to cause burns and other personal injury.
·Be sure to check whether there are loose bolts before flying. When install a muffler, the muffler in the threads of the
screw into the engine exhaust, until twist fixed, it is recommended to use screw glue.
·Ensure the engine and muffler in aircraft fairing environment with cold air, make sure the engine cooling.

Carburetor initial setup:
High speed needle:Completely closed before exiting 1.2 turns; Low speed needle:According the "View 1"
Idling start time the air inlet: According the "View 2"


Install the CDI ignition spark plug cap
The hexagon of spark plug and plug cap need align and then push down the spark plug cap and clockwise rotation it.

Starting the engine:

1. According the engine connection method, install the engine on RC airplane. Made the carburetor initial setup and
connect the electronic ignition, put the fuel into the oil tank, connect the power and radio control equipment.
2. Will power off the electronic igniter at this time, make the carburetor inlet port in a fully closed position. Through the
motor starter rapidly rotating propeller engine make the fuel in the tank inhalation of carburetor, please pay attention
to the suction of fuel should not be too much, otherwise will drown the spark plug, the engine start difficult.
3. Please open the carburetor throttle air inlet in "View 2" position, power on the electronic igniter, then start the engine
using the motor starter, the engine will begin to work, the fans will adjust the carburetor according to your own need:
Firstly please adjust the high-speed, the high-speed oil needle will along the clockwise from the oil-rich state to the
inferior state transition, make the engine work in the stable state of high speed (please note: do not let the engine run
boundary for a long time, this is a big damage for engine). Secondly adjust the idle speed, to control the air inlet
between 2.8mm to 3.2mm which showed in "View 2" (about a third), adjust the idle speed oil needle along the
clockwise or counterclockwise direction, make the engine work in the stable state of idle speed (12 * 6 proposed APC
propeller idle speed 2500 RPM).
Note: The small gasoline engine running at idling, the carburetor intake oil injection is a normal phenomenon.
Fuel pump: it is composed of pump and regulator, which have the effect of pumping oil and regulating flow, and
responsible for engine fuel supply; It has two sides, the side which has one screw fixed the cover plate is pump; the
other side is regulator which has four screw.


Fuel Pump Failure Removal:When oil supply failure, please check the connection of fuel pump is correct, if
necessary, you can carefully open the both sides of the cover plate and then check whether the diaphragm is intact,
Whether the oil hole plug, Whether the float adhesion, you can also clean the regulator float hole. When the fuel
pump can work normally and the engine start trouble let the engine in the stationary state. Check the carburetor
throttle valve outlet, Observe whether there is a fuel flow from the carburetor throttle valve outlet. If there is a fuel
flow from the carburetor throttle valve outlet, Due to fuel regulating float hole in the fuel pump have stolen goods or
impurities cause float cannot be completely shut down float hole. Please be careful open the cover plate and
diaphragm on sides, clean float, rocker arm, spring assembly and float hole, after cleaning the continuous press
rocker arm softly. Observe whether spring is able to return and float in the float hole can smooth movement up and
down, Then after the cleaning and inspection,according to the original appearance assembly.
Notice: Please note the assembly direction and position when dismantled the diaphragm to prevent wrong.


Engine Failure Removal:If the engine is difficult to start, please check: whether the electric circuit and oil line of
engine is trouble, whether the electronic ignition works or idle is rough or its power supply is adequate, whether the
SG spark gap of spark plug is between 0.5mm and 0.6mm, whether the engine leaks air etc.


Engine Break-in:Please use the high quality synthetic oils, gasoline and machine oil\'s mixing ratio is 20:1 or achieves
higher 25:1, Recommend smaller size propeller, Keep medium speed running for 15 minutes (no more than 4000rpm)
after started engine, then high speed running (9000 rpm) for 3 minutes, again medium speed running for 5 minutes,
high speed running for 3 minutes, reciprocating 3-5 times complete break-in. Breaking in engine carefully will
increase its life. Please make sure the engine got the complete break-in before you use the larger load propeller.
Engine cooling: If your engine is installed in the fairing, there must be air entering to cool the engine and ensure
enough air flowing in the faring. Reference data: To ensure adequate cooling, exit area is 3-5times bigger than
entrance area.


Engine Maintenance:To reduce the fuel consumption, extend engine\'s life, please adjust the engine\'s highest speed
and make engine run in the output maximum speed of 90% once the gas full opened. If the load is large (Propeller \'s
diameter and pitches are big), the fuel must be adequate. If the load is small, the speed will be high while the fuel
consumption will be less. Please make sure to empty the fuel pump after each flight, or it\'ll cause the rubber of fuel
pump aging to affect the engine performance. So please clean the carbon deposition on the spark plug and keep the
gap from 0.5mm to 0.6mm between the electrodes. If it\'s difficult to start the engine, idle is rough or stall in the
high-speed operation, please replace the spark plugs. Please clean the engine surface after used each time, it can make
the engine get better cooling. The fuel pump may be blocked seriously if you use different brands or types of
lubricating oil together, you need select a better fuel filter. If the engine is operated with long time and low speed, it
will cause the spark plug fouling. Always check the oil system to make oil proof and gas proof.


Engine Guarantee:If the NGH engine has performance defects caused by the defects of process, material and
manufacturing, we certify that: Change for free within one year and Guarantee within two years since the date you
purchased. Please note the guarantee is only for the original purchaser, not including: Normal wear for engine;
damage caused by the failure of maintenance; damage for engine over speed operation caused by using small

unreasonable installation or operating environment; Damage caused by improper dismantle; Damage caused by any
modification.
