VORTRIXE & OKMO M26 Old Tractor Engine Four-stroke Water-cooled Gasoline Model Engine
Introduction:
This is a mini gasoline engine model designed with the same structure as a real diesel engine; the only difference is that it runs on gasoline.
Each part is carefully designed and processed from brass and stainless steel, featuring a water-cooling structure.
The water tank has a capacity of 30ml, with a float and benchmark to show the water level.
Double flywheel design reduces low-speed response, and the flywheels on both sides of the engine are mounted with pulleys of different sizes.
It has a tape oil system for adjustable speed and a throttle switch to control engine speed. The igniter is powered by 4.5V.
This engine uses gasoline as fuel and becomes a small but powerful machine when launched. Starting method: external force (high-speed drill).
Features:
Engine Startup Steps:
1. Check the wiring of the engine from the board, connect the fuel tank pipeline, and install 3 No.5 batteries (4.5V).
2. Fill the fuel tank with 95# gasoline. After filling, rotate the flywheel clockwise on the right side of the engine (power switch surface) multiple times to remove air.
3. Turn on the power switch and quickly rotate the flywheel clockwise on the right side of the engine to start the engine.
Precautions:
1. If the ignition device and cylinder compression are normal but the engine cannot start, the carburetor oil needle may need adjustment.
2. After tightening the main oil needle on the carburetor, loosen 1/4 turn and start the flywheel to achieve the correct gasoline-air mixture.
3. Turn off the power switch when the engine stops.
Product Maintenance Method:
- The engine is water-cooled; add water before each use and save the water after operation.
- Ensure a clean working environment to reduce dust entering the carburetor.
- The carburetor oil needle is pre-adjusted; avoid large adjustments, but fine-tuning is possible with different fuels.
- The cylinder head cover can be removed to lubricate the valve mechanism.
- Remove the battery after use.
Troubleshooting Method:
- Use a new battery to ensure sufficient voltage for the igniter.
- When adding fuel, air may enter the tank. Cover the carburetor port by hand and rotate the flywheel to allow the piston to draw fuel into the carburetor.
- Fine-tune the main oil needle if necessary based on fuel type.
Lubrication Method:
- Add no more than 4ml of lubricating oil to the crankcase for splash lubrication of the crankshaft.
Fuel Type and Amount:
- Oil tank capacity: approximately 15ml.
- Compatible fuels: gasoline or aviation kerosene with 4% lubricating oil.
- If there is no compression, a foreign object may be preventing the valve from closing properly.
Methods to Resolve Foreign Object Issues:
1. Put a few drops of lubricating oil on the carburetor and use an electric drill to run the engine, expelling foreign matter and restoring cylinder pressure.
2. Rotate the engine in the opposite direction (counterclockwise) with an electric drill to discharge foreign matter.
3. Remove the cylinder head and inspect the valves. Clean foreign matter to restore cylinder pressure.
4. Check the valve timing gear for misalignment or disorder.
Note:
1. Product colors may vary slightly due to different monitors and lighting conditions.
2. Slight deviations in measurement data are normal.
