I often ask questions in Channel, email, and website in the comments – "how to determine what is knocking in the engine"? Many even pieces videos take off in social networks. But often cannot be determined,...

A few years ago, I had article how to clean spark plugsin it I spoke in detail about the chemical method of cleaning. However, many of us resort to the old sandpaper (in the people – "the skin"), a metal brush or even a file or needle file! Personally, I saw myself in the Parking lot when a guy is this method tried to remove the deposits from the iridium candles (just to get) is extremely wrong. So I decided to write an article about proper cleaning, as usual the video version at the end of the article...

Continuation of Part I... How to wash a car engine? I will say this, I am not a supporter nor a "KARCHER", no pouring of the power unit from the hose. Do not wash the engine Karcher I think this is wrong action (don't try to convince me). Indeed, in one case you pressure can tear all the wires, otherwise you can just fill in some necessary blocks (although the second method is more safe, because the hypothetical car, designed for wet weather and puddles). BUT I have a third solution (drum roll) — it is a sprayer for trees...

There is a lot of debate about cleaning the engine. Some say that this is a must, and do several times a year (I have a friend that summer, with his own hands, washes almost every month). Others are against it, say — that after washing, many things can damage, contacts are oxidized, and the car is normal not running. And where is the truth? What should they do? I will try to Express my opinion (it is my personal and does not claim to scientific papers). If you become interested, read the article + as usual the video version at the end...

Continuation of Part II... As I wrote above, the first generation of fuel injection systems in which the blow-by Gas raised before the throttle of the ball is far from perfect. Why? Yes, just because,...

Continuation of Part I... And here begins the most interesting, namely the device of the recirculation of crankcase gases, they can be separated from relatively "old" to the progressive "new". The old device. Everything was just "like a drum", from the crankcase release of a special "tube" (hose) sometimes it was even just a box on the block, which is simply connected with the atmosphere, Yes, they just went into the atmosphere. Then all was absolutely "on the side" on the environment, the vehicles do not have any systems ecology (such as catalysts , etc...

I am often asked questions about the blow-by gases of the petrol engine. Namely, what is it? What is the source? Ask a question about the valve (this system), ventilation system and so on. In this article to tell you will not work, because it's just a great material (I will write a few articles), but will try here to begin with — that is, where are the dangers and is it possible to release them into the environment. THE CONTENT OF THE ARTICLE First, it should be noted that these gases it is absolutely...

Now in the automotive market a huge amount of BU cars. And if you are considering such a purchase you want to be sure that this "Iron Horse" for another run. One of the most important points is the engine (it has to be properly checked)...

In many of my videos and articles where I indicate a syllable about the neutral gear, the hill and fuel consumption, my readers or viewers begin to write: — don't put "neutral" on the hill, the flow will be much more than if you would roll in high gear (say fifth or sixth). Some wrote – "fuel consumption is generally negative," what the onboard computer shows almost negative. That is nonsense!!! That is, a car dressed out of thin air or what? Today I decided to do an experiment it will be useful to many skeptics and "professional"...

Maximum torque – as it becomes clear we need more to fill the cylinders. For this you need to open much earlier and is far too late to close intake valve, to keep the mixture inside and prevent its release back into the intake manifold. "Prom" is in turn closed with some advance Btdc to leave a little pressure in the cylinder. I think it's understandable. So, now employs many similar systems, of which the most common Renault (VCP), BMW (VANOS/Double VANOS), KIA-Hyundai (CVVT), Toyota (VVT-i), Honda (VTC)...

The principle of operation Are not going to go deep, our goal is to understand how they work. Actually normal camshaft on the end of a camshaft gear, which in turn is connected with a belt or timing chain. The camshaft with the phase shifter on the end is a little bit different, redesigned. There are two hydro or electric controlled coupling, which on one hand also rests on the timing and on the other side with the shafts. Under the influence of hydraulics or electronics (there are special mechanisms)...

The efficiency of the internal combustion engine depends on the gas exchange process, that is filling the air-fuel mixture and exhaust already exhaust. As we already know, this is a timing (timing mechanism), if it is correct and "subtly" customize it under certain rpm, it is possible to achieve very bad results in efficiency. Engineers have long been struggling with this problem, it can be solved in various ways, for example by impact of the valve or by turning the camshaft. THE CONTENT OF THE...
