Starting a cold engine injector winter

Here's a little bit of theory and one of the recommendations on this subject: It is of great importance to the cold start is something to which the fuel supplied during the very start. At the old, carburetor models with low compression all happened quite simple: air valve closed, the amount of air at the time of launch regulated choke, but the amount of fuel was determined by opening the throttle at the moment of launch. The fuel from the carburetor at this point during the intake pipe, which is quite long. The road fuel in the form of a film on the inner surface of an inlet pipe in a way, too, was quite long and extensive over time. Notice immediately that the dose amount of fuel in the form of a film on the walls of an inlet pipe is much easier than in the vapor phase. The path from the nozzle to the combustion chamber at vpryskovom engine for a few tens of times smaller than the gasoline version. Let me remind you that jet fuel spreading on the plate opening in the combustion chamber intake valve. Paramount importance is how much is the vapor phase of fuel comes at this point. This is completely determined by evaporation of fuel. Conditions for the ignition to the strong may vary due to differences in the fractional composition, which are difficult to control and regulate.

Spark plugs

Spark plugs, of course, operate in the most extreme conditions, which only can be found in the car. They are then in turn "at the epicenter of the blast" hot gas with temperatures up to several thousand degrees, then take a portion of the working mixture, which had just formed from the atmospheric air (at ambient temperature), and gasoline vapors. All this is repeated dozens of times every second for hours.

The main task of the whole design is to create a spark gap, which is periodically passed through a powerful electric charge voltages of 20-30 thousand volts, creating an arc, which set fire to the working mixture. Most small deviations of parameters leading to unstable, especially noticeable at idle speed, and sometimes to a complete stop, or the inability to have an engine. The main reason for such deviations are the accumulation of products of combustion of gasoline, slaughter spark gap.

Alloy wheels or forged?

It is generally accepted that installing the light alloy rims, you can achieve two objectives - to improve the running characteristics of the vehicle and its appearance. However, experience shows that buying and installing "beautiful" drives changes in the behavior of the machine is not found. Why? The reason is very simple - as a rule, car owners, changing the boring stamping on the bright discs, increasing the diameter of the wheel. Along with this growing and his weight. Consequently, the dynamics remain the same, improved accelerating dynamics of the suspension and braking system, you can hardly feel. How to make light of the disk is not only beauty, but comfort? This is our present material. What makes alloy wheels? Virtually all sold cast and forged discs are made of aluminum alloy, that is, they are based on aluminum, which added many other elements of the table Mendeleeeva, including metals. Various additives make it possible to make alloys, respectively, and drive the desired properties. Discs of magnesium alloys - are rare. The history of the use of magnesium in the manufacture of the disc comprises at least 26 years old (Alfa Romeo Spider 1980 release is equipped with such discs). Thus far, however, magnesium disks are exotic. The feasibility of the use of magnesium alloys (usually with aluminum and magnesium supplements of manganese and zirconium) are determined by a significant reduction in weight of the disc and, consequently, reduced unsprung weight of the car.
