Installation of BSZ on Izh Jupiter-5: advantages of the system

08.05.2017

Installing a contactless ignition system on Izh Jupiter-5 is a fairly current topic. When setting up a BSZ on Izh Jupiter-5 BSZ, it is necessary to take into account a number of nuances that can significantly affect the operation of the equipment used.

What advantages open up to users who decide to install electronic ignition on the Izh Jupiter are described below.

Most modern motorcycles are not equipped with cams, that is, breakers. Why did the manufacturer consider them unnecessary for currently sold models? The answer is quite simple. This system is not very reliable.

Many parts used in the system are sources of trouble. The most common ones are listed below:

This will not be enough to fully accumulate the energy resource in the coil. In what cases is ignition adjustment necessary?

The voltage at pin 3 is formed by a measuring circuit consisting of a phototransistor and resistor R4, which equivalently constitute the same divider.

During the operation of the vehicle, the owner faces many problems. Scooters and mopeds Electrical circuit of IZH Jupiter 5 Unlike many Soviet-era motorcycles, the electrical wiring diagram of IZH Jupiter 5 was created for battery use with water-cooled equipment. It is advisable to use a pin, since many are not able to perform all the necessary actions in total; A set of wires with connectors for ignition without contact from VAZ. Of the entire mass, only a common plus is required. It is better to take a coil for 1-cylinder devices. In other cases, you should pay attention to previously grounded spark plugs.

The ignition timing must match on any cylinder used. Motorcycle wiring IZH Planet 5

Non-contact ignition IZH JUPITER 5 Non-contact ignition (BSZ) IZH JUPITER 5 On IZH Jupiter 5 non-contact ignition

- easily!
He was deprived of contactless ignition, and this is not nonsense. Of course, if you put up with the constant “headache” and periodically adjust the gap and clean the contacts, then the traditional “battery” system works. Fig. 1 Drawing of the modulator plateFig. 2. Schematic diagram of contactless ignition: 1 - spark plugs, 2 - ignition coils, 3 - switches, 4 - Hall sensor connectors, 5 - ignition switch, 6 - battery. Once the battery gets low, starting a cold engine turns into torture. When a motorcycle sits for a long time and every time you need to recharge the battery, it takes time, and you really don’t want to lose it... “Laziness drives progress” - so the idea was born to adapt the IZ Jupiter 5 BSZ
- I will be independent of the condition of the battery.
One of the issues of “Moto” described the installation of a Kovrov generator and ignition on various domestic motorcycles. But changing the standard Izh Jupiter 5 generator
with its 140 watts to 90 watts of “Zidov’s” is illogical: the energy of the “lighter” will decrease, and the lighting will “dim”.
Another disadvantage: Kovrov generators cost almost one and a half thousand rubles in the store, and you will also have to spend money on making an adapter faceplate. It is better to use contactless ignition parts from the VAZ-2108. I wasn’t greedy and installed two Hall sensors and two switches for each cylinder. This goodness cost only 500 rubles. Symmetrically “placing” the sensors in place of the remote breaker contacts turned out to be a simple matter: four plates from a children’s construction set perfectly hold the entire assembly (photo 1). All that remains is to make a chopper (modulator) and attach it to the rotor shaft of the Izh Jupiter 5 generator
.
I settled on the simplest option - I made a metal plate with a hole for a mounting bolt with a spring washer (Fig. 1). I looked at the connection diagram for the ignition elements in a car reference book. True, I have two of them, circuits, and they work in parallel - each candle is serviced by its own autonomous system (Fig. 2). The modulator plate moves freely after loosening the bolt, so it is easy to adjust the ignition timing - just set the plate in a position that ensures sparking - when the piston approaches TDC. I placed both switches on the frame under the motorcycle seat - next to the generator stabilizer (photo 2). Field tests were successful. A spark appeared immediately, even more powerful than before. Later I also replaced the ignition coils with “Planetovskie” ones - they are specially designed for non-contact ignition. an ignition system
on my is not a single failure and not a single adjustment.
The engine runs smoother, the spark plugs are cleaner and last longer - I have never changed them either. Now, even with a half-discharged battery, the engine starts easily. Addition:
Not only the motorcycle industry, but also automobile factories stubbornly continue to equip engines with a long-outdated contact ignition system.
Its only advantage is its simplicity of design. There are many more disadvantages: electrical and mechanical wear of the contacts occurs, there remains a need to frequently service them, the spark energy drops when the rotation of the engine crankshaft accelerates, as well as when starting the engine. The system described above is more advanced and reliable: it retains all the advantages of powerful battery ignition (spark energy - 12-20 mJ, discharge duration - 1.5-2.5 ms) over capacitor ignition (4-10 mJ and 0.3 -0.5 ms) - traditional for light motorcycles, including “Zidov” ones. In addition, by installing the ignition on Izh Jupiter 5
according to this circuit with a Hall sensor, normal sparking will be ensured when the battery voltage drops to 6 V. The circuit is somewhat overloaded; one could use one two-channel switch or a two-terminal coil. But there is a cloud without a silver lining: if the spark “disappears”, for diagnostics there is a “parallel” ignition branch at hand, serving another cylinder, and VAZ spare parts are always on sale in both city and roadside stores (which cannot be said about “Izhevsk”) . The simplicity and relatively low price of the alteration is another advantage. Photo 1. 1 - Hall sensor, 2 - modulator plate, 3 - mounting bolt with spring washer Photo 2. Both switches need to be protected from moisture (for example, placed under a motorcycle seat), but so, so that they are available for diagnostics.

Re: Non-contact ignition IZH JUPITER 5 Hello, I have a question about how to correctly install the breaker-modulator on the shaft, the principle of its operation and where you can find a mounting bolt with a spring washer.

Installation of ignition adjustment for IZH motorcycles

Installing the ignition of IZh motorcycles involves adjusting the maximum gap of the breaker contacts. And the second most important point is sparking. On single-cylinder IZh motorcycles with a G-36 M 1 generator, the gap is set by turning the eccentric 1 either to the right or to the left, with screw 2 loosened. Before installation, you need to turn the crankshaft and stop it at the moment of maximum divergence of the contacts. In this position we adjust the gap. We set the maximum gap at the contacts to 0.35 mm - 0.45 mm.

It is advisable to set the ignition timing by removing the cylinder head. The piston must be located within the dead center distance specified in the manufacturer's instructions. For example, for Planet 3 – (3.5-4.0mm), Planet 4 – (3.0-3.5mm), Planet Sport – (3.5-3.8mm). In this position of the piston a spark should form. Adjustable by turning the entire breaker with loosened bolts 10.

On IZH-Yu motorcycles, adjustment of the gaps between the contacts of the breaker is carried out in the following order: turning the crankshaft with a kick starter, place one of the breakers in the position of completely opening the contacts and, loosening screw 4, using eccentric 3 set the gap, which should be equal to 0, 4—0.6 mm. Then set the gap on the second pair of contacts in the same way.

The ignition installation of IZh motorcycles is carried out with the spark plugs turned out. By inserting the probe into the hole for the spark plug in the right cylinder and turning the crankshaft with a kick starter, find the top dead center and in this position make two marks on the probe: one at the level of the hole, and the second 2-3 mm higher. Then turn the crankshaft again with the kick starter until the upper mark reaches the place where the first mark was made. m. t. In this position, the contacts of the breaker mounted on the lower base should begin to open. Setting the opening of the contacts is achieved by turning the base with loosened screws 2 and 7, which are tightened after finding the opening moment. The moment of rupture is determined using a light bulb connected to the breaker terminal and ground.

After establishing the ignition timing in the right cylinder, proceed to the same operation and in the same sequence in the left one, while turning the upper base of the chopper with screws 1 and 7 loosened.

Motorcycle Izh Jupiter 5 - technical specifications and photos

Soviet motorcycles today are considered valuable transport, because back then they produced really high-quality and fast equipment. The Izh Jupiter 5 motorcycle is considered one of these legends of the USSR.

The Izhevsk plant produced several models, including Planet 5 and others. But Jupiter 5 was remembered primarily for its unpretentiousness on roads and maneuverability. With its small dimensions, the model was able to achieve low fuel consumption.

pros

• powerful engine;
• sharp at start;
• spare parts for Izh Jupiter 5 are inexpensive and available;
• soft suspension;
• low cost;
• has 2 cylinders.

Minuses

• weak front fork;
• requires good ignition settings;
• high fuel consumption;
• Motorcycles today require frequent repairs.

Technical characteristics of Izh Jupiter 5

The design of the motorcycle was created in such a way that in the end Izh could ride equally comfortably both on the highway and on uneven roads. Unlike its brother IZH Planet 5, this model had 2 cylinders, which means more power. Also, the owner of the motorcycle could start the engine more easily, which is explained by the absence of the leg returning when started.

Review

Classic transport has always been valued since the USSR, and 20 years ago Jupiter 5 was one of the best.

Today, most riders ride foreign fast motorcycles, but occasionally you can meet a former legend of the 80s and 90s.

In those years, only his brother Planet 5 competed with Jupiter, but he could not compare with the motorcycle in terms of characteristics. Their main difference was the difference in cylinders, and therefore power.

If we continue to compare these two competitors, we can highlight the fact that both models had almost the same data.

For example, they had one tubular frame, and a special subframe was installed to better secure the rear wheel.

In general, the entire design of Jupiter 5 was quite standard and simple, the engine was attached to the frame, the fuel tank was located above, and the headlight and dashboard were installed on the steering wheel.

In the photo of Izh Jupiter 5 you can see that below the seat there are two compartments with protection. These were glove compartments, each of which was intended for a specific purpose: the right one was for tools, and the left one housed the battery.

There were also 2 exhaust pipes installed that ran through the entire motorcycle. Sometimes the pipes got hot and could cause a burn, but the manufacturer installed them below the footpegs to keep the passenger as safe as possible.

Even the first models of the Izh Jupiter 5 motorcycle had simple drum brakes with a mechanical drive, but subsequent modifications received a front disc brake with a hydraulic drive.

Motorcycle appearance

When the Jupiter 5 model came out, its design was already well-known, because it was inherited from the Jupiter 4 motorcycle. But soon the Izh Planet 5 appeared on sale, and the developers saw that they could borrow several design elements.

The first modification had a square-shaped dashboard, which consisted of several indicators, an ignition switch and a speedometer. But soon its appearance was redesigned, and instead of one dashboard there were two. On the first part they placed warning lamps, and on the second part they decided to put a speedometer.

The design of the fuel tank has also been slightly redesigned, with rubber pads on the knees and the shape of the tank itself has become slightly different. Accordingly, in the new modifications of the Moto Izh Jupiter 5, it received a different, longer seat that ended at the brake light. This innovation is still considered stylish and modern.

During the Soviet era, creating high-quality and impressive equipment was as easy as shelling pears, because the country had all the resources for this. Thus, the Izhevsk plant produced a motorcycle that is capable of carrying a load of up to 500 kg. Just imagine what could be carried on this transport!

Being a workhorse, the motorcycle had a fairly sporty appearance and excellent top speed. With a power of 25 hp. the motorcycle could accelerate to 120 km/h.

This is a completely standard indicator, because another representative of the Dnepr could give a maximum speed of 110 km/h. In severe frosts down to 30 degrees, the unit started up perfectly, which cannot be said about the current new products.

Unfortunately, many owners complain of frequent engine breakdowns due to their long lifespan.

Price

Today, a motorcycle of this model is not so difficult to find; in Soviet times it was bought in large quantities, so today you just need to find out how much the Izh Jupiter 5 costs. Of course, the price depends on the condition, because over such a long period many parts could become faulty.

Even during the release of the Izh Jupiter 5 , its price was quite high - 1,050 rubles. But this did not stop buyers; they wanted a comfortable and fast motorcycle, which was the best then. But still, compared to other motorcycles, this model had a relatively low price. For example, then new Ural motorcycles had a price of 1,870 rubles.

If you want to buy a legend of the USSR today, be prepared to pay 55,000 rubles for a new motorcycle. Yes, they are still being reliably produced. If this price is too high for you, buy a used model - its price ranges from 5 to 40 thousand rubles.

1. BSZ
   - contactless ignition system;
2. Modulator
   - metal disk (steel 0.8-1.0 mm thick), plate, curtain. Installed on the axis of the ignition timing mechanism (distributor shaft). Produces “generation” of magnetic pulses to the Hall sensor.
3. Switch
   - an electronic device that supplies electrical impulses to the ignition coil;
4. A Hall sensor
   is a device capable of detecting the presence or absence of a magnetic field. If there is a field, a control pulse goes to the switch. The sensor position is fixed.
5. The ignition coil
   is a converter of pulses coming from the switch into high-voltage pulses supplied directly to the spark plugs.
