It would be better if he was silent or why Kuznetsov is smoking
The captain of Admiral Kuznetsov explained why his ship was smoking heavily: This is not a sign of any malfunction.
USS Freedom (LCS-1) There were also smoking Mistrals and some kind of Spanish aircraft carrier from World War II. But as it should be in the propaganda media, people don’t think what will happen next, the main thing is a momentary answer to divert their eyes. Yes, smoke often pours out of the chimney when the engine or boiler is started: at this moment, the ship’s power plant is usually “cold” and there are a lot of transient processes present in it. Sometimes this can only be an instantaneous release of the fuel mixture or condensate from the exhaust pipes, but sometimes it can “smoke like a charm,” such as the American USS Freedom (LCS-1) or the Egyptian Mistral. At full speed, to put it mildly, they are generally smokeless - this is the same ship that was called a smoking stealth on NTV (photo above): Black smoke when starting diesel or turbine engines is often the cause of butthurt in the Western press. “This is how we will show our stars and stripes (or some other) flag to the Swedes?” To which the admirals honestly declare: “Be calm, we will enter Stockholm at full steam, without smoke!” But, as they say, anything can happen. But when moving on the open sea and at full speed, black (blue, white) smoke is, unfortunately, a sign that the ship’s propulsion system is suffering from one of the listed ailments: it eats and burns oil, evaporates completely inappropriate water or it “drinks”, no matter how into itself, excess fuel, throwing soot into the sky. But this has never happened before :)
In mid-October 2016, one of the images of the National Aeronautics and Space Agency (NASA), taken from a satellite, appeared on the Internet, in which a smoky trail left by the aircraft carrier Admiral Kuznetsov, sailing along the Atlantic coast, is visible from space [funny, fake ]
Diesel injectors are not sealed
The next reason why a diesel engine has trouble starting when hot is the lack of tightness of the injectors. After the engine is stopped, some of the fuel continues to flow through the injectors into the combustion chamber of the diesel engine. Excess fuel prevents the subsequent start-up of a hot diesel engine.
Wet spark plugs will mean that the injectors are leaking diesel fuel after the engine is stopped. In such conditions, try to start the diesel engine by first opening the throttle valve. This will relieve pressure in the working chamber. To eliminate the malfunction, it may be necessary to repair or replace the injectors with new ones. It is also possible to overfill fuel due to wear of the injector O-ring.

Hello everyone, help me solve the problem I have a KAMAZ with a Bosch injection pump and an electronic pedal, turn off and start with a key. The problem is that it is very difficult to start for a long time. You have to turn it for 5-10 seconds, then it works smoothly. does not go away. and regardless of whether it is cold or just turned off! Has anyone encountered this? GOOD LUCK TO EVERYONE ON THE ROAD.

And this kind of crap started happening to me))) I noticed that the pump on the coarse filter died...an autopsy will show at the weekend.
There you need to wait for 5 seconds, and then use the starter. This is not your KAMAZ, my friend, with traction on the fuel injection pump, the control unit must set the rack to start mode.
I’ll support you about the valve on the filters - I’m a well-known brainiac. In addition, wear and tear on pairs and pumping. It wouldn't hurt to check the injectors either. if the diagnostics says nothing, try setting the angle a little earlier
I think it’s not the fuel injection pump, check the book for errors
I also changed the battery and started starting with half a kick...
We had this too, Bosch injection pump, if you press the throttle it won’t start at all, the pump was sent in for repair three times, nothing has changed and the car was written off, only one person could start it =)
Can't see the crankshaft position sensor
I don’t know how it is on Kamaz, but on my Scania the return valve died (or whatever it’s called correctly)) and the fuel from the system just went back into the tank. That’s why I had to oil it for 10-15 seconds. before starting. We changed this device and everything is fine.
The pressure should be measured in the injectors - when do they open? Maybe the injection pump takes a long time to create pressure
Haven't you looked at the forces? Perhaps some thread is draining into the return line. It will also take a long time to turn. The symptoms are very similar to the injectors.
I assume a slow increase in low pressure in the fuel injection pump housing 1. The valve, which is installed on the coarse filter housing (from which the tube goes into the tank), bypasses the valve. in fact, it’s not fucking needed there, it can be drowned out with a plug. Check it in the field like this - blow into it, if it poisons even a little - throw it in the trash. 2. The spring in the non-return valve has broken or weakened, the one that sits on the injection pump and drains the diesel fuel back into the tank. If the locking ball is very easy to press, you can knock the plug (in the form of a ball) a little deeper. 3. The valves of the low pressure pump are worn out - the valves need to be replaced.
There are several reasons. In my personal experience there were two on different machines. 1. The Pajero has a diesel engine, it takes a little too long to start, it turns out that the glow plugs are to blame. 2. The Fredliner has a Detroit engine. It took a long time to start, sometimes only from a quick start, it doesn’t matter, I just turned it off, cold, hot, no pattern and the same fuel did not go out, I thought maybe it wasn’t coming. Everything is cracked: fuel pump, tanks, fuel valves, etc. It turned out that the contact on the computer has oxidized and the voltage supplied to it is lower than it should be, but the onboard voltage is normal and the computer goes into emergency mode and does not allow startup. And when you spray a quick start, the speed rises and accordingly the on-board voltage rises, the computer has enough and it gives a start. I almost broke my head because of this.
Diagnostic specifics
The KamAZ engine can stall for various reasons, so you need to take into account the typical malfunctions for a specific car model. In some cases, clogs may occur due to low quality fuel, requiring professional cleaning.
In addition, each type of car requires special attention. For example, the battery of injection vehicles cannot be disconnected while the engine is running, you cannot perform actions with the batteries yourself, disconnect the ground on the car, or actively use charging and starting devices. When using diesel fuel, you need to remember that it is vulnerable to low air temperatures, as a result of which diesel sometimes freezes. The simplest are cars with gasoline engines, since they require a minimum of maintenance and are undemanding in terms of fuel and operating conditions.
KamAZ is also vulnerable to water, since its entry into the injector will lead to acidified contacts and breakdown of the technical system. To prevent unwanted problems, it is advisable to promptly change fuel filters and fill only high-quality fuel.
If KamAZ does not start, diagnostics are carried out taking into account the following aspects:
- is there fuel in the tank and is the fuel pump working;
- ignition system condition;
- Is the engine crankshaft timing sensor working?
- condition of injectors;
- technical condition of the ECU.
Any KamAZ breakdown can be fixed, but the cost of repairs will vary.
Symptoms of malfunction of fuel injection pump KAMAZ 740, fuel injection pump KAMAZ 4310
Malfunctions of fuel pumps and regulators manifest themselves in a violation of adjustment due to wear of parts, which results in the occurrence of extraneous noise, overheating and fuel leakage.
The main reason for the malfunction of the fuel pump is wear of its parts, weakening of the tightness in the fits, increased gaps in the moving joints, violation of the location of the parts, and deposits on the surface of the parts in the form of dirt and carbon deposits.
The consequence of pump malfunctions can be a decrease in the supply of fuel in the required quantity and uneven supply. Failure to properly supply fuel is usually caused by wear of plunger pairs, pump discharge valves, plunger drivers, rack clamps, rack teeth and bushing gears, and clogging of injectors. Such malfunctions lead to a decrease in engine power and efficiency.
Uneven supply of fuel to the engine cylinders will lead not only to unstable operation at low speeds, but also to interruptions in the operation of individual cylinders, which will be accompanied by vibration of the engine block.
Fuel injection pump malfunctions include uneven start of injection and delay in injection timing of a multi-section pump, which occurs due to wear of the pusher adjusting bolt, roller axis, pusher and roller housing, ball bearings, as well as wear of the cam shaft.
Wear of plunger pairs and injection valves significantly affects the change in the fuel injection advance angle.
Worn plunger pair
A common cause of difficult hot starting of a diesel engine is wear and malfunction of the high-pressure fuel pump. A heated diesel engine does not start in such cases due to wear of the injection pump plunger pair.
To do this, you can pour water on the injection pump. It is also advisable to cover the fuel pump with a wet rag. Successful starting of the diesel engine after such manipulations will mean that the reason for the poor starting of the diesel engine when hot is severe wear of the plunger pair.
Additional reasons may also be aging of the oil seal or a broken pump shaft bushing. Such malfunctions indicate that there is an air leak in the fuel pump. Under these conditions, the part is not able to create the required pressure in the plunger area. This means that fuel injection pump repair is required, which involves replacing the oil seal and shaft bushings.
The main reasons why the KAMAZ engine does not start:
- There is no fuel in the fuel tank;
- Presence of air in the fuel system;
- Clogged or contaminated fuel lines of the KAMAZ power supply system;
- The fuel has thickened due to low temperatures;
- Malfunctions of the high pressure fuel pump (injection pump malfunctions)
- Clogged fuel filters.
To determine the malfunction of the power system, you should follow the chain from less expensive and costly faults to more costly ones, taking into account the flow chart for repairing the power system.

Let me start with the fact that I bought my swallow in February, it was -25 -30 cold, so I didn’t notice one very unpleasant problem for me. With the arrival of spring, when the temperature settled at about +10 +15, I noticed one feature of my engine, namely poor starting when hot, the problem appeared in its full glory in the summer heat. As soon as I arrived home and turned off the engine, after being idle for about 30 minutes, I then had to oil the starter for a long time to start the internal combustion engine, about 4 seconds, and then it caught on, adjusted and quickly returned to normal speed. For my meticulous nature, this seemed almost like a disaster.
