Goal: to make the bike more powerful. Chip tuning, as they like to call it, or programming the processor that controls the injector.
It's time to touch on the part of the tuning associated with the operation of the motor. Rather, fuel management and factors influencing the result. I'll make a reservation right away that I will not deliberately go into the field of programming control cards, but general principles I will describe the work. This is due to the fact that without knowing the ford you do not need to change any values \u200b\u200bin the maps, burned motors are not needed in the garage ...
So let's go ... Goal: to make the bike more powerful. To increase the amount of emotions, you can change the throttle knob to a short-stroke, you just start opening the throttle faster, which replaces 20-50 horsepower 🙂 But we are interested in a completely different story ... Chip tuning, as they like to call it, or programming the processor that controls the injector. Let's take a little theory, what does the processor control? This is the amount of air and the amount of gasoline, depending on the engine speed and the angle of the throttle valve. We will not be able to approach the question simply by programming the processor. The wrong processor 🙂 We have the first input, the amount of air that directly affects the delivery of maximum energy during combustion. Rather, we are interested in feeding into the engine, as possible more air.
Point one, air filters.
In the standard, motor vehicles are equipped with conventional filters. The principle of operation is simple, air (dusty) enters the filter, and then passing through the filter cells already enters the engine. Filters are divided into 2 types: serviced and not serviced.
Disposable filters change as they become dirty.
Using this example motorcycle honda CBR1000RR Fireblade air is drawn in through the center of the filter and passed to the outside, from where it enters through throttle valves into the engine.
The disadvantage of these filters is the limited amount of air that air cells can pass. An example very well illustrates, when diving with a mask and a snorkel, you inhale sharply. That is, the section of the tube is sufficient for normal breathing, but not at all enough for a sharp inhalation with a full breast. That is, you are experiencing a lack of air. The same happens when using conventional filters. They can let in a lot of air, but they cannot do it quickly. That is, when speeding up, the amount of air is smoothly injected, but it is impossible to get it abruptly. The solution that allows you to solve this problem is the use of filters of zero resistance. "Nulls" are the same filters, but with higher bandwidth. That is, per unit of time they are able to pass more air than ordinary ones. But as you know everything has back side medals. Zero filters are designed for track use, that is, in places with less dust and dirt. Consequently, they have less protection of the engine from debris. Moreover, when using filters in everyday driving, they will have to be cleaned at intervals of 500 km and lubricated with a special grease for "zeroes". If this is not scary then go ahead. For example, you can take a zero resistance filter from K&N. Bandwidth this element is plus 40 percent compared to a conventional filter. The use of more expensive materials in the filter allows you to get an increase in power for little money. People say 🙂 that the increase in power is up to 10 percent. In my opinion, the entire exhaust system assembly can give such an indicator with the correct tuning of the intake map, but a zero-wheel can provide a sharp response to the throttle stick. The principle of the filter is shown in the picture. The outer layer traps coarse debris, sand, etc. Additional protection provides a special impregnation, which is desirable to add from time to time. If this is not done, complaints appear that the motor is jammed, but as it was disassembled it was full of sand. A naturally shriveled filter lets in a lot of debris. (For information, in many horse trams, filters are not used at all ... But there are disposable motors ... The middle layer filters fine debris and dust and lets clean air into the motor.
The filter is a very important element of the fuel combustion system. With the correct setting, the motor vehicle will go very fast, with the wrong setting, vice versa. Many people complain that when the zero-wheel was installed, the motorcycle began to ride badly. This is primarily due to the standard fuel and air supply card. The computer thinks they are conventional filters and creates a mixture based on this understanding. That is, opening the dampers more and giving as much fuel as is written in the map. In the case of zeroes, the card gives the command to open the dampers to a certain angle, and receives a lot more air. Consequently, the proportion of gasoline must be changed ... And a certain amount of gasoline is given. And it turns out either a poor mixture or a rich one. Hence the burned-out valves and pistons. Everything should be tuned to a common correct system work. The air / fuel mixture must be blended in strict proportions for maximum power output. Therefore, replacing the filter will not give anything but a change in engine operation (for the worse, naturally). There is usually a dip at low revs, there may be some delay on the middle ones too. But in the upper range, the motor works fine. We need maximum power throughout the range. Go ahead.
Serviced filters are washed and lubricated with special grease. To a greater extent, this concerns the crossover technique, although nulls are also lubricated for better work... IN motocross motorcycle the filter is large and made of parrolon. The task after each race or training session is to carefully remove it, wash it in special liquid, grease and put in place.
Motorcycle - hovercraft
This small-sized hovercraft is not accidentally called a motorcycle. Its mass, speed, power and payload are almost the same as those of these popular two-wheeled vehicles. And to make it even easier than a motorcycle. The foundation of the WUA is a platform-building on which two power plants - main and injection, driver's seat and device controls.
The platform-hull is all-wood: its deck, bottom, trim and aerodynamic ring of the supercharger are made of four-millimeter plywood, guide posts that orient the air flow are made of linden blocks 40 mm thick (their maximum thickness is located at a third of the length, counting from the nose), corners support skis - birch. All these elements are assembled on casein glue, only the aerodynamic ring is molded to the body with strips of glass cloth impregnated with an epoxy binder. Reinforcing kerchiefs are also attached to the epoxy. Finally, the body is vyskurivat, impregnated with linseed oil and painted.
The skirt is an important structural element involved in organizing the air cushion. It is made of a tarpaulin strip attached with small nails to the deck. The bottom of the skirt is hemmed and tied with a cord.
The driver's seat (in this case taken from the kart) rests on an aerodynamic ring and is attached with an 8mm stud (front) and to the supercharger casing (rear). Above the backrest there is a 2 liter polyethylene canister - a fuel tank. It is raised so high so that the fuel flows to the carburetors by gravity. One refueling is enough for about 15-20 minutes of engine operation (depending on the mode).
A modified IZH-112 engine was used to drive the supercharger. The essence of the improvements is as follows: the volume of the combustion chamber has been reduced - the compression ratio has increased to 8.5, the engine power has increased to 18 hp. at 4600 rpm. The gearbox is cut off and the standard generator is replaced with a magneto from the tractor launcher. The engine is equipped with an intake diffuser and muffler tailpipes.
To the shank crankshaft the propeller hub with a starting pulley is attached. A four-bladed propeller with a diameter of 670 mm and a pitch of 700 mm is made of two identical two-bladed propellers connected crosswise. Material - birch. It is attached to the engine hub with three M8 studs and an M12 centering bolt. The static thrust of such a propeller is 40 kgf.
The engine is installed above the platform on three tubular arcs of 33 mm. Two side arches are attached to the crankcase through rubber gaskets, the rear one is directly attached to the cylinder head.
The main engine is from the M-111 motorcycle. Its power is 11 hp. at 5500 rpm. The alterations are almost the same: the gearbox is cut off, a magneto, a diffuser and a muffler are installed, a propeller with a hub and a starting pulley is attached to the crankshaft shank. Propeller diameter 800 mm, pitch 400 mm, static thrust - 30 kgf.
The engine is installed cylinder downward, which made it possible to lower the position of the center of gravity and reduce the overall dimensions of the entire apparatus. However, this arrangement had a significant drawback: sometimes it floods the candle with fuel, and the engine stalls. Therefore, as a way out, the use of the cylinder head from the M-107 motorcycle, on which the candle is installed on the side, is seen.
Control is concentrated at the driver's seat. On the right - the gas sector and the ignition switch of the supercharger, on the left - the gas sector and the toggle switch of the main engine.
In front of the driver's seat there is a foot control post for the device. A pedal parallelogram turns around the vertical axis fixed in the platform, the thrust from which (duralumin tube 14 mm) passes under the deck to the tail rudder. The rudder is installed behind the main propeller guard and operates in the stream propelled by its blades.
The steering wheel frame is made of pine slats (maximum thickness 18 mm at the toe of the steering wheel), covered with a nylon stocking and pasted over with two layers of mica paper.
The weight of the "motorcycle" is 70 kg. With a driver weighing 65-75 kg, the device is capable of moving at a height of 5-6 cm at a speed of 65-70 km / h.
Now about how to use the machine. The main engine is started first. After it runs steadily, the blower motor is turned on. Let it run at low speed, after which the driver takes his place.
During movement, control is carried out by changing the position of the center of gravity of the apparatus. For a slight change in course, a slight deviation of the driver's torso in one direction or another is sufficient. With a sharp change in course, they also work with a rudder. It must be remembered that the device reacts to steering deviation with some delay. This is the originality of controlling a "motorcycle" on an air cushion, unlike any other type of ground transport.

Australian Chris Malloy created a device that he called "air motorcycle". The length of this unusual vehicle 3 meters, the diameter of the screw installations is 1.3 meters, and the weight is 105 kg. The designer managed to achieve a relatively small mass of his vehicle due to the active use of foam materials and carbon plastics. The inventor claims that his aerobike can fly at speed. 278 km / h at an altitude of 3 km. If you fly at a speed of about 150 km / h, then a 30-liter fuel tank will be enough to cover 150 km.
As conceived by the developer, the propellers of the helicopter motorcycle rotate in opposite directions, which makes it possible to extinguish the active torque. Malloy has everything thought out: if the propellers suddenly fail, the parachutes will open. True, the inventor has not yet finally decided whether they will be located on the body of his aircraft or in the pilot's backpack. The Hoverbike is operated like a motorcycle.
Currently, Hoverbike has passed ground tests and is even far away from the earth's surface. The first flight will take place in the fall, and if investors show interest, Malloy plans to launch the Hoverbike into mass production. Presumably, the aircraft will cost about $ 40 thousand.
We are on the verge of a new era. Era when the car no longer needs a driver, electricity will replace fuel, sensors and displays are replacing analog gauges. Motorcycle production does not stand still along with cars. The American company Aerofex Corp has unveiled the concept of the future Aero-X model - Hoverbike.
How a flying motorcycle works
This aircraft has a design similar to a motorcycle, where instead of wheels, turbines are built to create the effect of an air cushion. The gyroscope and many sensors that control the inclination of the flight correcting devices help to keep on the tunnel propellers.
Presently maximum speed The hoverbike is 72 km / h, the maximum height reaches almost 3.7 m, but the safety of this vehicle is questioned. This is what slows down the launch of the project into a series. Although, roughly speaking, the safety of conventional bikes still leaves much to be desired. Even the most recent advanced inventions, such as a motorcycle airbag, can only be deployed at a speed of no more than 60 km / h. The Hoverbike is capable of lifting two people and traveling on a full tank of gas for over an hour. This expense is due rotary engine, in which the fuel burns down an order of magnitude faster. In addition to the rotor, today Hoverbikes are equipped with ion and gravitational engines, but so far each of them has drawbacks that prevent them from being put into operation. The problem with gusts of wind blowing off the device was solved thanks to the now popular quadcopters. In them, the same gyroscopes and accelerometers are responsible for the gusts of wind, which are electronically controlled and stabilize the position of the Aero-X.
Hoverbike price - safety price
The miracle of technology from California will go on sale in 2017. Aerofex has already received a large number of emails wishing to pre-order the aircraft. The Aero-X Hoverbike will be priced in the region of $ 85,000, with a commercial model going on sale in 2017 for about $ 85,000. You can pre-order now for $ 5,000.
A flying motorcycle is a practical thing, because it doesn't need roads, which means you can conquer endless off-road. There will be no problems with coordinating flights. the maximum lifting height will be limited. Driving a flying motorcycle is intuitive, clear, and most importantly safe, Aerofex assures. The modern, cutting-edge design makes this unit more desirable for people who want to stand out.
The founder of the company, and now the technical director Marc De Roche, considers getting rid of the "docking effect" a big breakthrough. This will allow people who know how to drive a motorcycle to immediately learn how to drive the Aero-X. Future prototypes will be controlled by the tilt of the pilot and the steering wheel.
So that future owners, distraught with the purchase, do not take their own lives in the device, systems are set up to limit the climb of speed and altitude. Also Russian oligarchs will love the idea of \u200b\u200badding airbags to the Hoverbike.
The air filter belongs to "consumables", which means it must be replaced. It is often changed either once every two years or after 7 thousand kilometers. It is not very easy to buy an original filter, firstly, you need to find it, and secondly, it is not cheap. Therefore, inventive minds have found a solution this time too. "Why pay more?"
So, for work you need: a filter for injection VAZ (sold in any auto shop, cost ± 5 $), sealant (can be replaced with polyurethane glue, Moment glue), scissors, knife, ruler, pencil and, in fact, the nail of the program, worn out filter.
Having collected all this together and having gained patience, you can start replacing.
The filter size may differ depending on the motorcycle. This post is based on the example of a Honda Steed 600. - Ed.
Step 1. Cut out the old filter element with a knife. After you have completely cut it out, you need to clean the surface and wash it with soap, or treat it with alcohol to degrease the surface.
After that, you get the following filter case:
Step 2. It is necessary to measure the dimensions of the filter (width, height and number of curtains).
Step 3. We proceed to the direct manufacture of the filter. To do this, remove the mesh from the back of the donor filter and disconnect the curtains as carefully as possible.
After that, you need to count the number of curtains and divide them by two (in our case, the curtain of the motorcycle filter is half the donor curtain). Then you can cut off "all unnecessary". The crown rule is "measure seven times - cut one." The rest of the donor filter can be set aside until the next change.
Step 4. We have determined the length of the filter, now it's worth dealing with the width. We make markings along the entire length of the donor filter and carefully cut it out (we measured the width earlier).
Step 5. We rejoice at what we have achieved. We have a decent filter blank.
True, it is twice as high as we need.
Step 6. Refinement of the filter. We make markings for further convenience when folding the curtains.
You can use a ruler when folding. This makes the edges smoother and faster.
Step 7. Rejoice! In your hands new filter... Why not compare with the old one?
Step 8. Apply sealant to all places of contact with the filter housing. It is better not to feel sorry for the sealant and smear it with all the heart, so that in the future the filter does not let excess air pass.
Step 9. Insert the filter, level the curtains. We push all the sealant that "slid" with the help of available tools into the right places. We bring everything into the "Divine form" and wait until the sealant dries (it dries for about a day).
Step 10. We rejoice at our perseverance, and for the money saved we buy "ice cream for children, flowers for women"
