Trouble with UMZ 4216 Euro 3 Gazelle engine: causes and solutions

The engine heats up and starts to stall: why does this happen?

Almost every car enthusiast sooner or later encounters such a fairly common malfunction of the internal combustion engine, when the engine stalls. As a rule, in certain situations the engine stalls when hot or only when cold, and tripping can also occur constantly (regardless of the temperature of the power unit, operating mode, load level, etc.).

In short, engine tripping means that one or more cylinders are not firing, and there can be several reasons for such a malfunction. In this article we will talk about why the engine stalls after warming up, how the malfunction can be diagnosed, and what signs help to accurately identify the problem.

The engine stalls when hot: causes and common faults

Let's start with the main features. Often, a cold engine starts quite normally, but then begins to stall after partial warming up or completely reaching operating temperatures. In this case, tripping can occur both at idle and under load (while driving).

• You should start by checking the control system (ECM) and the engine power system. It is recommended to immediately carry out computer diagnostics and check the condition of the injector and injectors.

In any case, incorrect readings or malfunctions of sensors (lambda probe, temperature sensor, mass air flow sensor, etc.) and actuators can cause a hot engine to fail. Based on incorrect readings, the ECU may well over-enrich the working fuel-air mixture and flood the spark plugs.

• Next you need to move on to the spark plugs. At the initial stage, you should remove the spark plug high-voltage wires and unscrew the spark plugs from the BC. Next, a visual inspection of their contacts and insulators is carried out. Normally, candles should be dry, grayish in color, without a heavy layer of soot.

If the spark plug is wet and/or oily, then it is quite obvious that too much engine oil is entering the combustion chamber or the fuel is not being burned in the cylinder. In any case, a wet spark plug does not allow the cylinder to operate normally. Let us add that often both causes are often present simultaneously or are a consequence of each other.

If all the spark plugs are wet, you should check the oil level in the internal combustion engine. When the level is elevated (often as a result of overflow), the oil pressure in the lubrication system after the engine warms up exceeds the norm, excess lubricant penetrates the combustion chamber and contaminates the spark plugs. The result is a weak spark.

You also need to check the crankcase ventilation system. For example, the breather hose may become kinked, contamination may occur, etc. The main thing is that problems with this system also lead to pressure rising and excess oil entering the cylinders. If the hot vibration disappears after pumping out excess oil and cleaning the crankcase ventilation system, we can talk about a successful solution to the problem.

If this does not help, the spark plugs themselves will require increased attention. It is likely that even if the spark plugs have recently been changed, they will turn out to be incorrectly selected for the engine in terms of heat rating and will be “cold”; also, the spark plugs may simply fail or the product will be defective. To check, you need a kit that is known to be working (it is better if the spark plugs were removed from another car). If the engine does not start in these sections after warming up, then the spark plugs need to be replaced.

If it turns out that the dry spark plug in the cylinder has become wet, then it is worth checking the high-voltage ignition wire of a particular cylinder. The wire needs to be replaced with a working one. Also note that the problem may not be in the wires. For example, on carburetor internal combustion engines, a common cause of ignition problems is the distributor (ignition distributor).

On injection engines, failures can result from breakdowns of the ignition coils. In the case of a distributor, the device must be disassembled, dried, cleaned the contacts and made the necessary adjustments. If we are talking about an engine with an injector, you can swap the ignition coils and wires. This method allows you to quickly identify a faulty coil.

Tips and tricks

Please note that in order to check the functionality of the ignition system, in some cases it is recommended to check the spark plugs for a spark. It is important to understand that if you simply unscrew the spark plug from the engine, the presence of a noticeable spark on the electrodes is not always a sign of complete service.

At the same time, checking the coils cannot be carried out by diagnostics or various tests, since in many cases the problem can be “floating”, and in the case of the test the readings will be normal. Finally, we note that practical operation identifies problems and malfunctions in the operation of ignition coils as one of the common causes of engine tripping after warming up.

There can be many reasons, read about the most common reasons here - https://avtoexperts.ru/article/troit-dvigatel-prichiny/

The first thing to do is check the spark plugs, armored wires, and coils.

check the compression in the cylinders first

Everything is fine with the tags. Why everyone is talking about the exhaust manifold is not clear. Personally, I drove with a rattling exhaust pipe for 15-20 thousand and did not observe any jerks. (Once upon a time it was summer, season). The consumption was a little higher, but the muffler didn’t shoot, which means you can drive. There cannot be a leak in the exhaust because there is exhaust pressure there.

Malfunction and solutions

The reasons for the occurrence of tripping and blinking “Check” are almost identical for all power units. The root cause may be improper formation of the air-fuel mixture or a breakdown in the ignition system. But, everything is in order.

Poor quality fuel

Low-quality gasoline, or in common parlance - “bad gas”, leads to the fuel supply elements becoming clogged, and the injection system itself forms a lean mixture. To diagnose and troubleshoot the problem, it is necessary to test the injectors. It is better to carry out this entire operation on a special stand. If it turns out that the elements are clogged, then we can say that the vehicle was operated on low-quality fuel.

Another reason could be a clogged fuel filter, which is recommended to be changed every 20,000 km. Also, it is worth examining the performance of the fuel pump, which may fail.

Ignition system

Breakdowns in the ignition system, namely malfunction of spark plugs, high-voltage wires and ignition coils, can lead to a tripping effect. So, you need to unscrew the spark plugs and inspect them for defects. Also, using a simple tester, measure the resistance of the high-voltage wires, which is 5 ohms.

Air supply

The formation of the air-fuel mixture is influenced by the state of the air supply. A clogged air filter element or throttle valve can cause a rich mixture, which can cause a tripping effect. To eliminate the malfunction, it is necessary to dismantle and inspect the elements.

If the air filter is clogged, it is recommended to replace it, but the throttle valve must be cleaned with a special product or liquid for cleaning carburetors.

Software problem

Repeatedly, the cause of the tripping and blinking “Check” is a malfunction of one of the sensors or accumulated errors inside the electronic engine control unit. So, it is necessary to diagnose the condition of the elements and replace damaged ones.

ECU diagnostics

In order to understand which of the sensors or components affected the unstable operation of the engine, it is worth conducting a comprehensive diagnosis of the on-board computer. This requires an OBD II cable, a tablet and laptop, and software.

It is recommended to turn to professionals for help, who will quickly and efficiently perform diagnostic operations and fix the problem.

Deciphering error codes

If the car owner nevertheless decides to fix the problem on his own, then he will need to decipher the error codes that will appear on the diagnostic computer screen. So, let's look at all the error codes and their interpretation for the UMZ 4216 engine:

Misfire Gazelle Business 4216 reason

Are misfires detected by the lambda? Maybe a snag instead of a lambda?

most likely not, most often when the cylinders are turned off, the data from the LZ does not change. I don’t understand the algorithm of operation of this motor and this ECU at all, it contradicts any logic
