TNVD System

TNVD System

Often associated with engine failure improper adjustment of fuel equipment. Only a specialist in the presence of special equipment can make all the necessary scope of work to configure the system. If the machine or machinery is located in the park, where there are benches for repair – it greatly simplifies and reduces the work time on car maintenance. Otherwise, please contact the Autotechcenter. An attempt to independently adjust the fuel system can lead to more serious engine damage engine JAMZ. Setting fuel system in several steps.

In the first stage of certain parameters are checked injectors. Here, the expert drew attention to the mobility of the needle spray, spray quality and integrity, density and capacity dispenser. We study the cycle of the injection from the beginning until its end. At the same time made some mathematical calculations. In preparation for the regulation of the fuel pump specialists use nozzles that are developing for a particular model of pump. For the various units should be made their own kits. Thus, engines YMZ can not be configured with nozzles manufactured for other engines. When commissioning the gas pumps, in accordance with the technical documentation, specialist performs adjustment of valves, fuel injection start the various sections of the fuel system, the magnitude of the angle of the pusher and start pumping. Adjustment of performance allows optimize the various elements of the Yaroslavl factory fuel pump TNVD.Regulirovanie TA (COMPACT series 32) to check the opening pressure injection valves serve to fuel injection pump head, and gradually increasing pressure, watch for any pressure starts outflow of fuel from the drain pipes.

Think Oil

Think Oil

And if you do not have time to drown out the engine in time, everything will be much more complicated and will result already in the repair or replacement of the engine. Cases where the time to notice the flow of oil can not be too abound. And if all this will occur far from the city? History! Overnight, the route to the nearest village 100 km. Speed of 130 km / h, suddenly hit on the bottom and the oil pressure light lit up. Stopped – a hole in the crankcase of a piece of ice on the breakaway vperediiduschego truck! Frost -15, but the car does not zavedesh – oil, all on the road.

Well, as you think night someone stopped and dragged to the nearest town? Of course not! And all because he did not put the defense! The story of my friend who after this event lain with pneumonia. So Think it might come in handy one time. Hull is nice, but who needs a tow truck cause hemorrhagic, plod to the dealer, wait for repairs, etc. So put, put, and I will put before us the road would not be normal. 'Well, that to me it just does not happen! " – You may exclaim. I must disappoint you – we all think so, as long as it's not happening to us. Every day while you're driving down the road, you face potential danger. And you know that the most unpleasant? You can not predict when it will happen! 'I go only on good roads', 'I drive carefully and always look at the way' – that is in these words is a bug – it depends not on YOU! It may seem that this lock the door and do all that is necessary in order for me to get your attention for 20 minutes … I promise this time will bring you much good.

It must be remembered that each time you start the engine (not necessarily in the frost, and even at positive temperature) it takes some time to pump the oil has circulated for oil lubrication system, and it came to all the rubbing parts. At this time the engine will just be run in both Oil-called "starvation" of which we have mentioned above. It is clear that this dramatically increases the friction and wear. Thus, more oil is able to maintain fluidity at low temperatures, the faster it will be pumped by the lubricating system and help protect the engine. The best in this regard are motor oils of OW.

Regarding the choice of the so-called "summer" class, it should be noted that the pain * Most European Car manufacturers recommend the use of oils of class "40" by SAE. This is due to high thermal stress of modern internal combustion engines and the presence of high temperatures, pressures and specific shear rates in different parts of the engine (piston rings, camshaft, crankshaft bearings, etc.). In these harsh conditions keep the viscosity of oil should be sufficient for the formation of an oil film and cooling of friction pairs. This task becomes especially urgent in order to prevent increased wear, scoring, and "jamming" in the summer or during a long stay in the "traffic jam" (in the absence of ventilation and cooling motor currents and counter-air, as a consequence, the oil temperature in the crankcase), as well as in the case of engine overheating due to potential malfunctions in the cooling system.

Car Maintenance Amount

Car Maintenance Amount

If compression is insufficient air temperature reaches the ignition temperature of diesel fuel and all the contents of the combustion chamber without the use of "fly out the chimney." Hopefully, now it is understandable why the compression line some normative value is very important for the normal functioning of the engine. That is why the "Guide to Car Maintenance" usually indicates the amount of compression that has certain value for a given engine. In addition to the operating values are also the permissible tolerances, because, unfortunately, over time, seen as projected, and unexpected changes in compression (usually smaller). On the fall of compression indicate problems at start, rough work, the deterioration of vehicle dynamics, increase fuel consumption. It's time to talk about what to do with compression? To answer this question, please use elementary logic.

As seen by those who have already read the content technical help, the compression ratio is constant for the motor. This means that every time the piston in the cylinder draws the same amount of fuel mixture and, moving toward the top dead point, reduces it (squeezing the contents of the cylinder) in the same amount of time. What is the reason that as a result of compression does not create the proper pressure? It is logical to assume that somehow leaking volume in which the compression and the process is accompanied by leakage of the compressible substance. This reduces the original amount of the mixture, drop in its pressure and temperature prior to ignition.
