After the first systems that automatically run the engine appears in the markets, it was possible to hear many different opinions and arguments about this - both positive and negative. To understand whether to establish a similar mechanism on its vehicle, we will consider all its advantages and disadvantages in detail, the principles of operation and learn to make the motor autorun system yourself.

Engine autotoprotev - Convenience to the driver in the cold time

Undoubtedly, much more convenient and more comfortable to sit in the car and immediately start moving, than to spend your time on reanimating the frozen motor. Once, it was possible to only dream that the car will start the timer in the morning and the engine will warm on its own, now it is real.

In fact, the idea of \u200b\u200bwarming the motor when the driver is missing, not at all new, albeit on passenger vehicles, is applied relatively recently. Primary, such technology was used on trucks, in which the freezing of the liquid could give very sad results. By the way, for passenger cars, the device is capable not only to heat, and cool the interior, including air conditioning at the right time.

The automatic motor start module can be operated automatically or remote mode. In the first case, you only need to configure the number of attempts and start time, and in the second - just click the button on the keychain. In some cases, the GPS receiver can be replaced by control via SMS commands from a conventional mobile device.

Principle of operation of autorun.

In technical terms, the automatic launch of the motor will not be difficult. Electronic board having the ability to program, you need to connect to the necessary sensors and ignition through the relay. The unit can be positioned anywhere, the system does not have any special requirements, not counting electricity. The chip must be combined with such mechanisms:

1. Entering.

2. Tachometer (to control the operation of the motor)

3. The end of the hood.

4. Speed \u200b\u200bsensor.

5. Oil pressure sensor.

6. Gas pedal.

7. Lever gearbox and parking brakes.

8. Candle of the heating (for diesel engines).

At the predetermined time, on the chain that connects the power to the ignition, switches the relay. Next, through the sensor in the highway, the oil pressure is checked with the subsequent starter start. As for diesel engines, you need to still control the candles of incandescent.

There are several start-up attempts. By default, three attempts have for each relay, however, the settings can be changed. If all attempts were not crowned with success, modern autorun systems are able to skip the information through a fairly simple algorithm and send causes to the abnormal mobile phone.

Car alarm with autorun, how to achieve interaction

Running the motor is designed to shut down or bypass certain signaling functions. Therefore, the autorun system is very difficult to interact with the vehicle protection system. In the case of a block connection with a security complex, most alarm sensors are turned off, after which the ignition is activated. You can purchase an immobilizer crawling unit separately, since it is not expensive.

Those who are developing security complexes are required to create varieties and protection during the engine running. Often, when the engine is running, the defense charges are assigned to the terminals. One sensor is on the stop signal terminal. When the alarm is received, all sensors are turned on, doors are blocked, etc.

Automotive system, how to make it with your own hands, the course of work is styled

Make a autorun system yourself quite real. If there is no signaling on your vehicle, you will fit the most simple scheme. Otherwise, you will need to be around the immobilizer.

The scheme is quite simple for embodiment of it, nothing will need, except for contact relays, three or four pads to them, soldering iron and tape. If you have auxiliary outputs on the alarm of your car, for example, to open the hood, then you can do without a timer. The diagram made will be connected through them and run the keychain.

Alarm is not capable of feeding the voltage itself, however, it connects the power supply with the diagram. For this, one of the relay is bothering that runs the entire system. But it lasts a similar connection for a short time, on this one wire should be displayed on the handbrake terminal. As for the third relay, it is assigned to the starter.

Also, you can operate a button that remotely opens the doors. To do this, you must slowly disassemble the key and apply a fee that is responsible for activating the motor. The typical reader, which is located in the ignition lock, is connected by a thin wire with the extracted board.

Warming up the car can be carried out without starting the motor. In this case, the warm-up machine is used, which runs from the car battery. Do not forget that performing installation, the latter must be connected to a positive wire.

Engine autorun - advantages and disadvantages

Advantages of autorun:

1. Cold time motor and vehicle interior fraction.

2. On the hot season of the year chilled salon.

3. You significantly save your time.

4. There is a turbotimer option, which allows you to stop the engine turbine gradually, and this has a positive effect on the resources of the device.

Disadvantages and cons system:

1. In a very cold night, trying to raise the temperature to the optimal point, the system can plant the battery. To prevent this, correctly set the time of the motor activity, which is enough to have been charged back.

2. The vehicle protection is significantly reduced. To avoid lowering security, you need to purchase a special system of alarm that can work with autorun.

3. If the autorun system is incorrectly configured, you will receive a couple of cold starts for the night and none in the morning.

4. With strong frost and cold wind, the fault of the system, the exhaust pipe can be frozen. This happens when water condensate is formed in the exhaust pipe.

5. Immobilizer is temporarily deactivated during autorun.

6. Fuel consumption increases. However, with independent warming of the car, you also spend fuel.

7. If you put the vehicle in the winter time on neutral transmission, brake pad cables or manual parking brakes can face.

8. When a manual parking brake device is weakened, the car can spontaneously start moving, especially if you are standing on a slope.

Several tips:

1. Increased exhaust pipe with autorun, it is necessary to set the motor overheating timer at the desired time, for example, ten minutes. Thus, the vehicle will not work long at idle, and it means that the water condensate will not form.

2. When freezing the parking brake cable, it is possible to shoot down from it by the following method - remove the wheels, pull the handbrack flag back into the rear position and pull the cable. Cold pads and set the wheels back.

3. If the parking brake device is relaxed, put a piece of brick or anti-tank pads under the wheels.

We draw conclusions

The autorun system is not a magic wand, however, a fairly convenient tool in the winter season. Remember that the above disadvantages are characteristic only for cars with a manual transmission, on this, when installing, do not forget about risks. Also, it should be remembered that when autorun activation, the vehicle security system will be disabled, which can lead to the hijack of the car. In addition, when around the immobilizer, it is necessary to use a spare key that can detect an attacker during penetration into the vehicle. Therefore, before equiping the car with this device, you must weigh and thoroughly think about all its pros and cons.
