Exploring the Charm of a Mini Gasoline Engine: A Model Inspired by China's First Diesel Engine| EngineDIY

 

In the hectic pace of life, finding a hobby that belongs to oneself is undoubtedly a way to relax and enjoy. Today, I would like to share with you a miniature gasoline engine model that has fascinated me deeply. It is not only delicate and compact but also imbued with rich mechanical charm and technical wisdom.

This miniature gasoline engine is inspired by China's first diesel engine and meticulously scaled down to a 1:8 ratio. It measures 145mm in length, 108mm in width, and 106mm in height, weighing just 1500 grams, yet it boasts a displacement of 3.6 cubic centimeters. Such a design makes it a perfect engine model for both collection and display.

When I first encountered this engine, I was captivated by its exquisite craftsmanship. The cylinder diameter is 16mm, equipped with brand-new metal piston rings, and an oil cup is installed on the piston, ensuring stability and durability during engine operation. The cylinder liner adopts an upgraded cast iron honing sleeve, further enhancing the engine's performance.

What is more astonishing is that this engine is internally equipped with a gear pump, and oil passages are cleverly designed on the crankshaft and connecting rod. When the engine runs, oil flows through the connecting rod into the piston, providing excellent lubrication for the piston and cylinder liner, realizing a true independent lubrication system. Such a design allows the engine to run stably for a long time without damage due to overheating or wear.

Beyond its superb craftsmanship, the engine's appearance is also highly attractive. It features two large stainless steel flywheels, providing greater working inertia and thus achieving a lower idle speed. The careful crafting of brass and stainless steel materials gives the engine an elegant and noble overall appearance. The water-cooled cooling structure and adjustable-speed carburetor further guarantee the engine's performance.

The engine features two large stainless steel flywheels that provide greater working inertia, enabling a lower idle speed. Crafted meticulously from brass and stainless steel, it incorporates a water-cooled cooling structure and is equipped with an adjustable-speed carburetor. The ignition system is powered by a 1.5V power supply, and it offers flexible starting options, including external force (such as an electric drill) or manual starting.


Engine Startup Procedure:

1.Check the engine wiring and fuel tank piping, install a AA battery (1.5V), and fill the water tank with cooling water. Unscrew the oil screw at the rear of the engine, add 5mm of oil, and then tighten the screw.
2.Fill the fuel tank with 95-octane gasoline. After filling, turn the flywheel clockwise multiple times to ensure that the fuel mixture fully enters the cylinder and avoid air in the fuel line.
3.Turn on the power switch and quickly rotate the flywheel clockwise on the right side of the engine (facing the power switch) to start the engine.

Precautions:

1.If the ignition device and cylinder compression are normal but the engine still fails to start, you may need to adjust the carburetor needle.
2.Tighten the main needle on the carburetor and then loosen it by 1/4 turn. Start the flywheel multiple times to achieve the normal operating mixture ratio of gasoline and air.
3.Always turn off the power switch after stopping the engine.


Product Maintenance Methods:

1.Since the engine uses water cooling, add water before each operation and drain the water after use for proper storage.
2.Ensure a clean working environment to reduce the risk of dust entering the carburetor.
3.The carburetor needle is adjusted to the optimal position before leaving the factory. Significant adjustments are not recommended, but fine-tuning can be made based on different fuels.
4.Unscrew the oil screw at the rear of the engine to drain the lubricant inside.
5.Remove the battery for storage after stopping the engine.

Troubleshooting Methods:

1.Ensure the use of a new battery to provide the required voltage for the igniter to operate normally.
2.When adding fuel to the fuel tank, if there is air in the tank, press the carburetor mouth with your hand, rotate the flywheel, and use the piston to draw fuel into the carburetor.
3.The engine is adjusted for operation (using gasoline) before leaving the factory, but when using different fuels, the carburetor settings may require fine-tuning by adjusting the size of the main needle.

Lubrication Methods:

Add no more than 5 milliliters of lubricating oil to the crankcase to ensure the proper functioning of the gear pump. Note: The oil quantity must not exceed 10 milliliters!

Fuel Use and Quantity:

The oil tank capacity is approximately 15 ML. The engine can use gasoline and aviation kerosene as fuel.

In general, this miniature gasoline engine model not only allows me to appreciate the charm of engine and the wisdom of technology, but also allows me to find my own fun and relaxation in my busy life. I believe that for friends who also love engine models, this engine will definitely become your favorite. Let us go further and further on the road of exploring the world of engine together!
