Novice motorists sooner or later have new questions, which can not only put a dead end, but also to create a misconception. Example, not everyone accurately and correctly imagines, what is engine attachment.
a little mat part
The car engine itself is a cylinder block and a cylinder head. Inside are the valves, crankshafts and camshafts, pistons and so on. In this form, the motor comes off the assembly line and the finished engine can be bought, when there is a need for a complete replacement.
However, to make this complex mechanism work, many more different devices are needed, who join him. In other words, additional equipment "hung". This is the engine attachment.
The specified attachment, used on internal combustion engines, are independent devices or elements of different systems. example:
- Generator. With the help of this node, everything is fed, consuming electricity in the car during engine operation: lighting, ignition, diagnostic system and ECU, on-board computer, audio system and so on.
- Starter. Detail, by means of which the engine is started. Its action is short-lived and ends at that moment, when the engine speed exceeds the speed of the starter (unit start up).
- Carburetor or injector. The carburetor is on cars of old models and prepares fuel-air mix, which is fed into the combustion chamber. The fuel rail with injectors is used on more modern injector engines instead of the carburetor.
- Diesel engine high pressure fuel pump (TNDV). At strictly defined moments, it delivers precisely diverted portions of fuel to the cylinders, the supply is realized according to the load on the motor, vehicle speed, etc..
- Turbine (turbocharger) or mechanical compressor. Serves to increase engine power due to forced air supply (under pressure) in the cylinders.
- The engine cooling system pump is a water pump, due to which the coolant circulates in the system. It is also worth noting the thermostat, which allows liquids to move in a large or small circle depending on the coolant temperature.
- The air conditioning compressor and power steering pump are also included in the list of motor attachments.
We also recommend reading the article about it, what is a generator in a car. In this article you will learn about the purpose and principles of this device in the list of attachments of internal combustion engines.
- Various ECM sensors and electromechanical devices (oil pressure sensor, RHX, DPDZ, DPKV, etc.). These solutions control the operation of the engine, transmit data to the ECU, as a result, the control unit maintains and adjusts the operation of the internal combustion engine in accordance with certain modes. Also, some sensors transmit readings to the dashboard in the car, allowing the driver to monitor individual parameters of the unit.
As a result
so, it is possible to draw a conclusion about that, that attachments are different devices, which ensure the start and normal operation of the engine. In case of breakage they can be repaired or replaced, without removing the entire power unit. It turns out, "Naked" engine comes without all that, included in the engine attachment.
We also recommend reading the article about it, What shall I do, if a knock is heard when starting the engine, creak or squeak. In this article you will learn about the possible causes of extraneous sounds, as well as ways to diagnose faults.
Further (that is, after installing the unit on the car) in the process of assembling the car in the hood space are mounted different systems, in parallel, the engine must be supplemented with all necessary attachments.
