Advice 1: How to determine which is the engine

Timely care about the car engine – a guarantee that you find yourself away from civilization with a broken car. A serious problem in the work car may be a problem with one of the cylinders, leading to the tripling of the motor. If you set a task to determine, which is whether the engine in your car, pay attention to the following points.
How to determine which is the engine
You will need
  • - the car;
  • - good hearing.
Instruction
1
Listen to the engine while riding and remember what the sound was before. Note whether the engine to run roughly, not to do the momentum. Try to accelerate and define "stalling" a car like you used to, lost it power. If you feel some of these symptoms in your vehicle, think about thorough technical inspection and repair, most likely, the engine troit.
2
Stand next to the exhaust pipe and listen to the sound of the engine. If you hear evenly are distinguishable "BU-BU-BU" characteristic "troadio" engine, do not rush to draw conclusions because of the poor performance may be simply the freezing of working parts. Run the engine for a while and again listen. If the sound has not changed, so the engine troit.
3
Try this method. During the trip, sharply press the accelerator pedal and acceleration. Listen: if the engine does not respond immediately, but first "zabubnil" (the sound "BU-BU-BU-BU-people moved), most likely, with one of the cylinders that something is not right, that is, the engine troit.
4
Start the car. Try to feel how the engine is running at idle: if it runs unevenly, twitching, with "failures", then most likely there are problems with one of the cylinders. The reasons may be different, including making engine, diagnose and think about the repair.
5
Start the car and open the hood. In turn remove the caps of nasosnikova, thereby disabling the spark from the engine. Listen carefully to the sound of the engine, if the sound has changed, then, with this candle it's all right, but if the sound has not changed – the problem in this candle.
6
If you still doubt it? if the engine, consult an experienced driver or a service station. Note that this breakdown is very serious and requires careful study of the causes and immediate repair.
Note
Ride on car, engine runs on three cylinders out of four, as dangerous for the machine and the driver as the engine catastrophically quickly begins to wear out and overheat. However, the service you get may be able (if it is not 1000 miles).

Advice 2: What if troit engine

Unstable work of the engine (the engine "troit") dramatically reduces power and increases fuel consumption. All that can be done in a similar situation - not in a hurry to get to the garage and investigate the reasons for the "wrong" vehicle operation.
What if troit engine
The reason "taenia" engine failure of one of the cylinders. To find out the cause of the malfunction, you can conduct your own diagnostics. It is sometimes possible within a few minutes to find the cause and eliminate it. But there is another situation when to restore normal operation of the engine required major overhaul. Why not works the cylinder?

Bad plugs, faulty ignition system



First you need to determine the inoperative cylinder. To do this, start up the engine, put it on the lowest possible speed. Then alternately remove high-voltage wire from each spark plug. If when removing the engine there is no noticeable hearing change, so we can consider this cylinder is inoperative. Remove the candle from it and inspect it: cracks, reflow, chipping is not allowed. It is best to put new set of spark plugs in all cylinders. If such a replacement is not successfull, you have to go to the next step check the ignition system.

One of the reasons for the fault could be a broken wire. If it doesn't work, the voltage doesn't reach the candles. To verify correct wire, disconnect it from the spark when the engine is started up (use rubber gloves – high voltage!) and move to a distance of 4-6 mm. the Presence of a spark is talking about a working ignition system. If there is no spark, try replacing the wire on is OK. When the spark does not appear, in this case, check the ignition module or distributor cap (if a car with a carburetor).

Low compression, lack of fuel



In other words is insufficient pressure in the cylinder. To understand whether this is so, you will need a helper and a compression gauge. For the measurement, disconnect the high voltage wire from the ignition coil, and remove the candle. In the vacant hole, insert the instrument and have an assistant key the ignition to crank the starter for a few seconds. Observe the maximum reading of the instrument. This guide operation with all the cylinders. Considered normal pressure of 10-14 bar. Minimum 8-10.

Another reason not functioning cylinder – lack of fuel-air mixture. This can occur due to improperly adjusted valve clearance, or faulty injectors. In the latter case, it is advisable to contact the technical service because of the repair work, adjustment of the injectors require special equipment.
