IZH Planet-4, the photo of which is presented below, is a classic version of a middle-class road motorcycle designed to ride on completely different tracks. The production of this model was carried out by the Izhevsk Machine-Building Plant. The popularity of the motorcycle speaks for itself, because almost everyone had (and have) it.
Brief General Information
The engine, which was installed on the IZH Planet-4 motorcycle, had a fairly large thrust. At the same time, work was carried out at relatively low speeds. It was possible to attach a side trailer (passenger or cargo type) or a universal module directly to the motorcycle itself. In addition, it was possible to attach additional knee shields and trunk. In order to reduce the force when disengaging the clutch, IZH Planeta-4 uses a multi-plate clutch. In combination with an air cleaner, vibration dampers for the edges of a cylinder of increased volume help to reduce the noise level that is produced by a motorcycle. The front wheel of this model is equipped with a hydropneumatic suspension with a disc brake.
Modernization
The production of the IZH Planet-4 motorcycle has undergone a number of changes. So, a generator was used in the design, the operation of which is based on permanent magnets. This part also has a non-contact type ignition system, which in turn works independently of the battery. In addition, the engine itself is equipped with a special separation type lubrication pump. This eliminated the need for a gasoline-oil mixture. The IZH Planeta-4 motorcycle is equipped with a four-speed gearbox with an eccentric mechanism to turn off the clutch and a more powerful motor chain. The front disc brake is hydraulically actuated, and the suspension system uses improved shock absorbers. In addition, the changes affected the kinematics of the brake drive for the wheel located at the rear.
Motorcycle Technical Features
Basic data: between the wheel axles the distance of 1,450 mm is set; with absolute load and tire pressure within normal limits, the ground clearance is 135 mm. Dimensions are as follows: length - 2200 mm, width - 810 mm, height - 1200 mm, weight (dry) - 158-165 kg, maximum load capacity - 170 kg, including a load on the trunk of 20 kg. Motorcycle power is 22 horsepower. At an optimum speed of 90 km / h, fuel is consumed at 5 liters per hundred kilometers.
Engine characteristic
The IZH Planeta-4 motorcycle is equipped with a 2-stroke engine with a cylinder size of 72 mm and a volume of 3,346 cm. The separate lubrication system is equipped with an oil pump that doses the feed depending on the frequency with which the crankshaft rotates and the load engine. There is a contactless electronic ignition system with regulation (automatic) of timing in the ignition depending on the frequency with which the engine crankshaft rotates. However, it does not depend on the battery. For work, it is advisable to use gasoline with an octane rating of at least 76. The engine uses an air cooling system. The transmission from the engine to the clutch is carried out using a drive sleeve double-row chain.
Gearbox
A four-speed gearbox is a three-shaft, it is located in one block with the engine. The gear ratio for the clutch from the engine is 2.17, with 2.33 to the rear wheel from the gearbox. Some more details about the remaining gear ratios: 1st - 3.88; 2nd - 2.01; 3rd - 1.26; 4th - 1.0. Suspension of the front of the motorcycle is telescopic type, and the rear - lever, with shock absorbers (spring-hydraulic). The rear brakes are drum-type, the front ones are hydraulic disc brakes.
What is the wiring of IZH Planet-4?
The motorcycle uses twelve-voltage equipment. Electrical wiring "IL Planet-4" single-wire type. The metal frame performs the minus task. Vividly demonstrates the main components of the electrical wiring of the IZH Planet-4 motorcycle, a diagram of the ignition system, power sources, side light and turns, as well as head light.
Generator
The motorcycle is equipped with a 3-phase alternator, which has an electromagnetic excitation circuit. The principle of its work is based on some features. So, the IZH Planet-4 wiring diagram is as follows: current is supplied to the rectifier, which, in turn, converts it to constant, then passes it through the ignition switch to consumers. The following elements are presented in the factory instructions of the generator:
- voltage regulator with rectifier "BPV-14-10";
- generator stator with windings;
- generator rotor;
- cam battery ignition system and the contact node of the ignition system;
- brush collector.
For reference: the windings on the three-phase generators of the IZH Planet-4 motorcycle are connected in the form of a star or a triangle, and the rectifier is installed in a separate unit and the wiring is connected directly to it.
Head lighting
In European countries, there is a requirement regarding the mandatory configuration of motorcycles and similar equipment with a battery with permanent magnet generators. There are no such restrictions in the Russian Federation. With the generator installed, the IZH Planet-4 motorcycle does not need a removable current source to start the engine. Accordingly, this is why the battery is not included in the basic package .
The headlamp circuit consists of a rear brake light, parking lamp and a blue indicator light . The motorcycle is equipped with a speedometer with mileage indicators (daily and total), a tachometer, indicator lamps for direction indicators and head light, a voltmeter and an engine temperature sensor. Very often during operation it is necessary to set the gap between the contacts of the chopper. To do this, it is best to use the circuit and special tools to know which elements need to be dismantled.
