In our last video on jet engines, we have learned that just like piston engines jet engines do intake, compression, combustion, and exhaust but the big difference is that in piston engines these events occur one after the other in every cylinder whereas in a jet engine, these events occur continuously, all the time and they occur simultaneously with each other.
In this video, we will explore how jet engines have evolved to become much more powerful and much more efficient. Now this engine is called a turbojet and by modern standards, this is very much obsolete. This right here is a turbofan, or more specifically a low by-pass turbofan, and an engine like this is nowadays most commonly found on fighter jets and other military aircraft. As you can see, even upon first glance, the engine is pretty different from our turbojet.
Now the first, and most important difference is that in a turbojet, all the thrust generated by the engine comes from the exhaust stream, or the jet of expanding gasses coming out of the back. In other words, all the air that comes through the front of the engine ends up inside the core which houses all the key mechanical components of the engine.
But in a turbofan, this is not the case. Not all the air ends up in the core, some of the air is bypassed around the core and never contacts the internal parts of the engine. So why would we bypass some of the air around the engine?
Well to understand that we must remember that jet engines are also called reaction engines. Essentially they move incredible masses of air. This movement creates a force. And as we know for every force there is a reaction force in the opposite direction. This reaction force moves the engine and because the engine is attached to the aircraft the entire aircraft moves.
This tells us that to travel faster and/or to move a larger heavier aircraft we must move greater masses of air. To move a greater mass of air we can either move more air or we can move the air faster.
A turbofan engine exploits the first concept and that is to move more air. Now we have two kinds of turbofans, a high bypass and a low by-pass turbofan. When a civilian like you or me flies in a commercial aircraft we are propelled through the sky by a high by-pass turbofan. A high bypass turbofan takes the concept of moving more air to the extreme because at the very front of the engine, we will find a giant fan. This is where the name comes from, turbofan. We have a giant fan and gas turbines at the back which harness the energy of the combustion and thus power the fan. Now because the fan is so large it is capable of moving absolutely incredible amounts of air and about 80% of the thrust of the engine actually comes from the fan and only around 20% comes from the exhaust jet coming out of the back of the engine.
Because most of the thrust comes from the fan it means that we don’t have to burn ridiculous amounts of fuel to move the aircraft. Modern fans are designed to be extremely efficient at cruising speeds and altitudes of commercial aircraft. The added benefit of the is that the bypassed air creates a sheath of air around the exhaust jet and this greatly reduces the noise pollution created by modern commercial aircraft.
But unfortunately moving more air has its limits. You can’t make infinitely large fans because the greater the size of the fan the greater the difference in speed between the blade root and the blade tip, because the tip covers a much greater distance than the root. In other words, an overly large fan will inevitably achieve supersonic speeds at the blade tips and this leads to inadequate and inefficient operation.
This is where low bypass turbofan engines like this one come in. Their bypass ratio is around 0.5 to 1 compared to the bypass ratio of commercial turbofans which is usually 9:1 and above. A bypass ratio of 9:1 tells us that for every kilogram of air going through the engine core 9 kilograms of air go around it.

11-1. V800W Carburetor Adjustment Suggestions
Notes: Due to the shared characteristics of two carburetors among eight cylinders, adjusting one carburetor may affect the conditions of other cylinders. Therefore, adjustment requires patience, multiple attempts, and skill acquisition through experimentation.
11-2. Dual-Cylinder Methanol Engine Single Carburetor Adjustment Method
Start by turning both main and auxiliary oil needles clockwise to the bottom. Then, turn the main needle out 4.5-5 turns and the auxiliary oil needle out to a gap of about 1mm. Begin low-speed break-in of the engine, and after 2-3 fuel tanks, the engine should start very well.
When adjusting the main needle, open the throttle to 4/5 full and slowly turn the main needle with a screwdriver. As soon as the engine sounds very sharp, it indicates the engine’s maximum speed has been reached. Do not let the engine sound like dry coughing, as it signifies a lean fuel mixture and can cause significant damage and overheating. For beginners, a slightly rich mixture is safer. Then, loosen the needle a few turns to provide a slightly rich fuel mixture, making the engine more powerful. At this point, quickly accelerate and decelerate the throttle; the engine should not stall, and the idle should be stable. The engine can reach speeds of up to 13,000 RPM, indicating normal operation.

The model engine industry has been developing rapidly in China for five years, and the EngineDIY team has been fortunate to ride on this wave. Nowadays, there are more and more products, and competitors are constantly joining. How can we continue to remain the leader in this field, and how can we help It has become our biggest problem for a single supplier to seek breakthroughs from the models made by many peers.
This year, we have been thinking about this issue repeatedly, so we have made great adjustments in the layout of this year’s major new products. Therefore, during the development process with suppliers, we chose to do top-secret work on this blockbuster new product. No details were disclosed in the early research and development stage, and the prototype fee alone cost 5W+. Now everything is in place and ready for release.
These two engines (with different structural designs) will be launched at the same time at the end of October. The design concept will restore the real engine appearance to the greatest extent. The prototype refers to the classic small block series, which run through the entire history of the American V8 engine. This is also the top level among all model engines in China (not abroad for the time being), regardless of design restoration. The quality and manufacturing process are all done with utmost sincerity.
The ohv version uses exquisite electrophoretic paint to restore classic colors
High angle, high hardness and wear-resistant cam
Enlarge the intake valve (larger than the exhaust valve)
Five-point support camshaft to prepare for high hardness valve springs
Lubrication system [oil pump splash lubrication cam, crankshaft, connecting rod piston; ohv version can be installed with rocker arm forced lubrication system (with rocker arm lubricating oil return cylinder hole), oil pan with oil dipstick]
Five-point fully supported crankshaft
Reinforced hardened and wear-resistant connecting rod
Dual cast iron piston rings (optional oil rings)
Ignition method: distributor (high performance cdi frequency 42000)
Cylinder block with oil filter element installation position
Optional four-hole carburetor for OHV version
Optional generator
In order to ensure that the intake manifold temperature does not affect the engine power, a low-temperature intake pipe is specially designed.
The cylinder blocks are processed using high-precision five-axis CNC with a repeatable positioning of 0.005mm, providing better accuracy guarantee for engine power.
The length of one side cylinder is about 95mm
The total length of the cylinder is about 100mm
The engine ratio is about 1:6
Displacement is about 44cc
Bore size 18.5 Stroke 20.5
The design speed range is 1500~10000rpm (the top speed of flathead and ohv versions is different)
Power is about 4.8ps
]]>Connection of CDI signal lines
The battery uses a 2S 7.4V lithium battery
We need to find a sleeve on the power distributor and place the main line and grounding wire inside the sleeve
Find another magnet, with the small triangle facing downwards, and check if the CDI can function properly
When Hall moves over the magnet and electricity is released, it indicates that the CDI can work normally.
Repeat the above actions to check for the next CDI
The positive and negative poles of the input terminal must not be reversed
Hall sen has north and south poles. When Hall sen does not discharge, turn the magnetic north and south poles and try again
All checks have been completed and there are no issues with the CDI. Let's put the CDI aside
We check the timing of the engine
There are three marked points here, all of which point downwards, indicating correct timing
The crankshaft point is downwards, and the camshaft two points are downwards.
Let's keep the three points stationary and place them here
Next, we will connect the power distributor
The power distributor is divided into left and right parts, with the one with a notch installed on
We will install the power distributor later
The power distributor has left and right sides. When we disassemble the power distributor, we must distinguish the left and right sides clearly and not confuse them
Open all of this and take a Hall wire, which corresponds to the location where the Hall is installed
Similarly, insert the small triangle towards the magnet and insert it all the way to the bottom. At this point, the left part has been installed
Similarly, we install the right power distributor
The power distributor on the right is the same as the one on the left, with the small triangle inserted towards the direction of the magnet, and it must be fully inserted
Next, we will install the distributor holder onto the engine
This is the picture manual that comes with our factory
When the left distributor is perpendicular to the position of the screw, the ignition angle of the cam is correct.
The distributor in this picture is on the right side. When a straight line below aligns with the center position of the screw, the ignition angle of the cam on the right side is perfect.
Installing power distributor
Here, there is a point at the position of the power distributor, with the installation method point on the left facing upwards
The same goes for the right side
After we have installed all the left and right parts, the correct direction should be one left and one right, with the left side facing up left and the right side facing up right
After this step is completed, we will install the distributor holder
Okay, next step is to install the spark plug
When we get an engine, here is the main oil needle, and on the right is the auxiliary oil needle
Let's first adjust the main oil needle. First, turn the main oil needle all the way clockwise, and then back out two and a half turns counterclockwise
Similarly, the adjustment of the carburetor is the same as before
The auxiliary oil needle is to fully open the throttle, and the distance between the auxiliary oil needle and the fuel injector is approximately 1mm
Then we connect the oil pipe. Using gasoline, the ratio of gasoline to engine oil is 20:1
Next, let's start the engine
To adjust the engine, it is necessary to first adjust the high speed of the engine, slightly increase the throttle, and then start it
The reason for not starting like this is because there is not enough fuel. We will open the main oil needle a little more and slowly adjust it not to open too much. Now that the engine has started, we will start the fuel valve. If the throttle is fully opened, it indicates that there is no problem with high speed.

1. Engine oil of appropriate quality grade must be used, which is the key to ensuring the normal operation of the engine.
2. Pay attention to the oil quality and whether the oil filter is clogged. If so, please stop the machine immediately.
3. If oil with moderate viscosity is required, oil with appropriate viscosity should be used according to the local temperature. It is a mistake to think that higher viscosity is better. Due to its high viscosity, the engine oil flows too slowly during startup, which can easily aggravate parts wear and even cause tile burning accidents.
4. Add antifreeze of good quality and do not replace it with ordinary water. Too little antifreeze will affect the heat dissipation of the machine.
5. When changing engine oil, it is necessary to drain the waste oil. In order to extend the service life of the engine, the old engine oil needs to be drained completely when changing the engine oil to avoid contaminating the newly added engine oil, affecting the rapid deterioration of the new engine oil, and causing corrosion and wear of the engine.
In most cases, first drain the waste engine oil at high temperature, then add washing oil (85% of ordinary engine oil, 15% of gasoline), idle for 10 minutes after starting, drain again, and finally add clean new engine oil.
6. Maintain normal oil level. When the amount of oil is insufficient, it will not only accelerate the deterioration of the engine oil, but also cause burning damage to parts due to lack of oil;
On the contrary, if there is too much oil, the oil will flow into the combustion chamber along the gap between the cylinder wall and the piston ring, causing the engine to burn oil. In addition, if the oil level is too high, it increases the stirring resistance of the engine oil, increases fuel consumption, and aggravates wear.
①Neither the starter nor the engine can rotate. First, check the battery storage condition and the wire connection and contact condition; if the battery is normal, check the starting circuit, fuse and ignition switch;
②Move the accelerator to the medium opening position, and then turn on the starter. If the engine can start at this time, it means that the fault is a fault with the idle speed control valve and its circuit or a leak in the intake pipe. If the engine still cannot start when the accelerator is at a medium opening position, the next step of inspection should be carried out;
③Perform appearance inspection. Check whether there is any air leakage in the intake pipe; check whether each pipe and its connection is intact; check whether there is any air leakage in the crankcase ventilation device
④Check for high-voltage sparks. If the high-voltage spark is abnormal, check the high-voltage wire, ignition sensor, distributor and electronic ignition;
⑤Check whether the ignition sequence is correct;
⑥Check the oil supply situation of the oil supply system. After confirming that there is leakage in the fuel tank, check the fuel supply pressure in the fuel pipe;
⑦Check the ignition timing and the ignition sequence of each cylinder;
⑧Check the working condition of the fuel pump switch installed on the air flow meter;
⑨Check the working condition of the spark plug of each cylinder;
⑩Check ignition timing. If the ignition timing is incorrect, the ignition timing control system should be further checked;
1. This machine is only suitable for adults over 18 years old!
2. This machine uses pure gasoline as fuel and has a high speed, which is dangerous. Please operate in strict accordance with the instructions!
3. Do not add other fuels except 92, 95 and 98 gasoline. The fuel must be clean, and keep the fuel away from sources of fire! If there are too many impurities in the fuel, it will clog the carburetor oil passage and reduce the engine's performance.
4. Do not put your hands or other objects close to the engine pulley and flywheel while the machine is running. Otherwise, it may cause personal injury and increase the risk of machine damage!
5. If the machine cannot operate normally, do not force it to start. Check the machine immediately or contact after-sales service. Otherwise, the risk of machine damage will increase!
6. The operation of the machine will produce a certain amount of noise and exhaust gas. Please try to operate it in an open outdoor area!
7. Please maintain the machine regularly, change the oil, clean the oil passages, and check the wearing parts. Will significantly increase its operating life.
