Engines MMVZ-3 115 often used on maps and — with appropriate upgrades-cooling system — tillers and microfracture. Among the works on their service, there is also such as installation of ignition. At first glance it runs just the ignition timing that is specified in the instructions to the engine corresponds to the rotor position sensor, when its longitudinal groove coincides with the projection on the winding frame sensor. But not always: the spark occurs either too early or too late than it should be. Apparently, due to the scatter of the electrical parameters of the switch.PUTTING THE IGNITION

What is a shame to damage the car at the entrance to a private garage! Unfortunately, this happens with young drivers is not so rare, especially if the garage is to put it mildly, does not differ too much space. Scratches on doors or wings and broken tail lights — that’s the usual consequences of inaccurate targeting.
Drivers know: after long Parking of the car in the cold to start the engine. At low temperatures freeze even antifreeze! And those who use it for cooling water and drains it at night, lose the opportunity to fill the radiator with hot water — burst frozen in the cold of the cylinder head and the block, and the boiling water almost immediately freezes, forming ice plugs.
Bike, perhaps the most common vehicle. And the fact that the most economical — there is no doubt that only two sandwiches to two hours to pedal. But is it possible to increase the efficiency of the human “engine”? With the reduction of spending “fuel”, nothing happens. Friction and the weight of the machine is reduced almost to a minimum. There is also a “box of speeds” the device for changing the gear ratio by switching the circuit to a small or large sprocket. It remains only to lengthen the levers of the pedals, but experts adamantly claim that their optimal length — 170 mm.
One of the main problems faced by the Amateur constructor engine aircraft — selection or production of the power plant the necessary power, weight and efficiency. This problem is solved normally, on existing capacities and experience of building such units.
The first little micro-car “mouse” I built for my kids. As a result, I accumulated some experience of designing and has already planned not as a child, and “adult” car. Called it “mouse-2”. Built a long time, or rather, not so much built, how many were looking for the necessary parts. This, in particular, due to the use of “Mouse-2” mechanical brakes (now I change them for hydraulic). Design drawings and the construction was carried out simultaneously, although the basic parameters of the “Mouse-2” was thought out by me in advance.
Camber angles and toe of the car very accurately can be adjusted, without resorting to service stations. We just need to have some plumbing skills and to have the simplest tool to their own to make for this adjustment tool kit, which is easy and convenient performance. Consider, for example, the variant with the car VAZ-21063. The distance between the centres of the footprint of the tire on the ground — 1365 mm. If through these points to carry forward in the course of movement of the vehicle two parallel lines, then they could become benchmarks for subsequent adjustments. However, it is impossible to carry: the protruding part of the side surfaces of the car will be a hindrance. Hence the need for these parallel lines to hold at some distance from the vehicle. To make that possible with the devices, which can be called a protractor.
For a start I suggest the readers-to motorists to conduct a little experiment. Once outside the town, stop by high-speed stretch of highway and watch whizzing past you cars. However, here you need not to watch but rather to listen. A quarter of an hour you will learn to distinguish aurally, the main types of cars: a sound portrait of the major role played by a characteristic noise of the flow over the body. But here comes a car with a roof rack and audio, the picture changes dramatically. The impression is that the car literally pushes through the dense unyielding environment. By the way, the impression is confirmed by experiments in wind tunnels. Purge models and full-size cars with roof racks have shown that increases dramatically the so-called Cx is the drag coefficient. But it depends on the speed and fuel consumption.
It is well known that the wind fairing is not a tribute to the motorcycle fashion, and not only protect the rider from the cold and dirt. A well designed shield can increase the speed with two-wheeled machines due to the reduction of aerodynamic drag. But the appearance of the motorcycle fairing attaches to consistency and completeness: the motor vehicle acquires its own entity, releasing the car in several thousand likes.
Growing every year in our country, the number of motorists. For many of them the car is not only a means of transport, recreation, but also technical creativity. It would seem, than still it is possible to add, improve released in a modern plant the design of a brand new car! But for the curious enthusiast with skillful hands here even boundless field of activity. To them and turned a new section of our magazine “Car “M-K”.
