Another mode of transmission is that the command is passed on regular wire car by a weak signal, similar to the interference from the spark plugs. The advantages of this method is that no wires are not connected directly to the alarm system and the output relay, hence the name of the relay – 'Wireless'. It can be hidden in a bundle of regular wires, find and neutralize it is practically impossible. But this method requires more security team itself – theoretically it can 'eavesdrop' and write any wire a car, so the commands must be encrypted variable code. The third way to – on the radio.
The security system is equipped with a transmitter, and the output relay – receiver. This method advantages of wireless relay continues, but has some limitations related to the fact that getting the team to allow the engine may be difficult because of interference. Situational relay may be possible to to determine what is blocking relay circuit, the absence of any signal or even the diagnostic reports a car. To prevent this, the digital relays are becoming more complex, and are ability to decide when they lockable chain must be restored, and when – no. For example, the relay can simulate engine failure, while taking into account what sort of circuit blocks it, and install the degree of 'seriousness' fault. This approach to the blocking of the engine is possible only if the security system of communication between its modules and actuators. Class channel management The most common and convenient control channel security system is to control the radio, using the remote control.
Long time digital relays have been effective in blocking – the relay will not work until the receive the command. A security system sends this command only at a resolution of a trip, and not when the car lights flashing and siren screaming hysterically. But what prevents hijacker bring security system, similar installed on the vehicle by connecting it to the cigarette lighter, to simulate the disarming? To protect against this in the management team include the serial number. Number does not match – the relay is not activated. Constant and variable code there Another danger: as long as relay itself is able to recognize a digital command, so you can make a device that just detects such a command, and then, if necessary, will even be able to repeat it. Kinda recorder.
If the command to restore a locked chain every time the same, then the thief can reproduce it with a tape recorder. To protect against such attacks, the command code make the variables every time new play already 'spent' code does not result in resolution of the engine. How to pass command to the digital switch? 'Wireless' control relay or the wire (data bus)? You can connect the alarm system and digital relay wire, as was the case with analog control, and pass on the wire team. Such control is called managed by a dedicated wire or bus. Its advantages include good Immunity and the complexity of connecting 'the tape'. The disadvantage – the fact that the output relay can be found by tracing where he goes wire management.
And what if the child in the car? Necessary to give the motorist a car seat sootetstvuyuschey age group! If this gift does not fit your budget – choose a beautiful child and to functional adapter harness. And if the car owner to the same breeder and – pay attention to safety belts Dogs and safety vests for four-legged friends. Surely such a gift and love the owner! Do not forget about the means to care for the car. Car treatment – these are different cleaners, polishes, Autoshampooes, air freshener, cleaner dashboard – gifts do not come cheap, but the car required for an appropriate and regular care. After all, one way or another, the motorist rather a lot of time behind the wheel. Gift for Motorist – it is also a functional thing.
Interest – interest, but the element of "usefulness" in the present – not less important. Present owner of the car radio cassette player or a modern, brand-new set of tools – obviously useful things. Or wireless mobile headset. Your friend has a? No? Give now! Take care of his safety. If the vehicle owner, planned a long trip soon, or in the nearest future well-deserved rest, then serve as a wonderful gift … the refrigerator.
But, of course, no home: the car with him to carry such a whopper … will not be easy. Compact, roomy and cool – choose Auto-refrigerators guided by these criteria. By the way, it is possible that the car – this is one means of recreation.
Dear motorists! Today we look at the most probable causes of engine power loss. Since even for vehicles with minimum run power does not always match the stated by the manufacturer. And the engine efficiency is reduced regardless of whether the same path. So: many engine manufacturers are struggling to have their engines fuel consumed during the minimum. Ie were cost effective. AND thus not only did not lose in power, but also had some of its stock. Isearch has much to offer in this field.
Many of you have seen the race in Formula 1. Sport engines are designed with the most advanced manufacturers of involving predovyh same technology. This is Ferrari, and Renault, and BMW, and Mercedes-Benz. Their specialists are very accurately calculate the engine power and efficiency. But this is with regards to sports cars, particularly Formula 1 bolide. The engine is targeted for only one race, and produces his RESOURCES for one race almost completely.
Imagine that such a 'shell' consumes about 60 liters of high octane gasoline per 100 kilometers. Do you think if your car is "gulped" the same, you smogliby its 'feed' (excluding spare parts)? – Of course not! – Reply to you. And where I am so worn? I'm not a Schumacher in the end! I do not propose to drive like Schumacher. Let's just look at the difference between sport and normal engine. And you will understand the reason excessive fuel consumption of your 'wheelbarrow'. Unlike Formula 1 engine from road engines. Completeness cylinder filling (volumetric efficiently (VE)).
