Motorists know how important it is for diesel internal combustion engines proper installation of the moment of ignition — the ignition spark of the spark fuel in the cylinder before the end of the compression stroke. In theory it should occur exactly at the end of this cycle. In practice, use a small spark advance below the maximum dissipation was carried out at the beginning of the next measure — extension. Otherwise you will not get far: the motor is getting “greedy”, but “pulls” very bad.

Device for Dismounting of bearings is shown in figure 13. They are as follows: from the bearing, remove the separator, pushing the balls enter between the collars of the bearing lugs is rotated 90° and in this position zakanchivaut nuts. Screw compress the bearing from the trunnion of the crankshaft. The demolition is over.
Bike engines D-5 is familiar to many designers and Amateurs. On their basis build different machines: microvesicle and motology, microaerobic and motonarty. Often readers turn to us with questions about the increase in power bike engines. We will try to describe the main methods of speeding up the engines D-5 and D-6 (to try to force the engine D-4 is not recommended, as this will require significant additional alterations, replacements, cylinders, crankshaft and other parts).
The start of the internal combustion engine of a car even in winter, after long-term Parking is often a big problem. To an even greater extent this issue is relevant for heavy duty trucks and automotive technology, many of whom are already in private use — because they are operated mainly in terms of outside storage.
The car’s handling and tyre wear, as we know, primarily depends on the state of the front suspension of corners of a longitudinal inclination of axes of rotation, and angles of camber and toe. As a rule, adjustment of all these parameters produce on special stands at service stations, but in this case it is not always the adjustment will be optimal for a specific vehicle and specific conditions.
Many cyclists, especially in provincial cities and towns, and put “on a trick” their “two-legged horses” and in the winter time. But winter is winter. Even four-wheel vehicles are recommended to be changed to studded tires. To say nothing about the less stable two-wheeled transport. Risk of falling with him and injury increases many times.
On own experience made sure that there are no limits to perfection for Russian motoakademija. To bend and digest the frame, to bring forward the plug, push back car, and the front Bicycle wheel is turbulent, in General, the imagination knows no bounds! However, when it comes to alterations of electrical equipment, mater biker often he scratches the back of his head, or goes cap in hand to the garage “special”.
Many motorists, especially the owners of domestic vehicles has experienced all the “charms” winter operation “beloved horses”. Special “pleasure” — after frosty nights to bring to life the heart — the powerhouse. I have a giant of Russian car industry — “Eye”, so all my thoughts and efforts were directed to develop a system that allows you to quickly and efficiently prepare the engine to start, warm up underhood space. respectively, the battery and create, if possible, a comfortable environment in the vehicle. The advantages of such training are obvious: easier to start engine at any temperature; reducing consumption of gasoline at start-up and engine warming up, which is especially great in the cold season; increases battery life by reducing the starting current on a warm engine, increase the service life of the starter by reducing the wear on the bushings the armature and the life of the engine.
Many accidents occur due to technical reasons, including due to faults of the brake system of the vehicle. One of the indicators of the effectiveness of this system is the braking distance, which for different categories of vehicles is regulated by state standard. Determined he may be on a special stand.
The characteristic trend is clearly revealed held in the summer of 1978 the VI all-Russian meeting of young rationalizers and engineers: in many rural schools children are actively engaged in the mechanization of labor on their educational sites. At the gathering, devoted to the 60th anniversary of the Lenin Komsomol young technicians from many regions and republics brought all kinds of tools and machines to facilitate agricultural labor. From motociclo and matatapos to small tractors of various schemes and designs is the range of the current Hobbies of students in rural (rural!) schools.
