Look bad tires, protect from cracking

Finally all the old tires. The aging process can be noticed through the increased hardness of the protective rubber and is determined by the small cracks on the tire surface. The increased hardness of the rubber leads to a change in tire traction.

Causes appear cracks: low quality rubber, improper tire storage, the effect of exhaust gas, ozone and sunlight, repeated overheating, moisture, maintenance does not timely tire, driving with flat tires, overloading vehicles.

Another reason for tire cracks is the occasional operation of the car. When the compression and natural tensions do not affect the tires, special preparations designed to protect the tires stop working, increasing the possibility of cracking. Applying special care products to tires allows for longer lifespan, reshaping the attractive appearance ("wet tire" effect), making the tire surface more durable for all types of tires. type of contamination. , discoloration and the effects of different atmospheric phenomena.

Difficult start (gasoline engine)

There are many reasons for the difficulty of starting the engine, especially in cold weather. The most common reason is the flammability of the air fuel mixture and / or the cranking engine is difficult to start.

Until the cause of the malfunction is eliminated and removed, the agent for easy motor startup can be applied. The agent contains special ingredients, which promote the burning ability. To start the gasoline engine, spray a small amount of it into the air filter or into the air receiver.

Water is condensed under the lid of the container

Condensation occurs on the inside surfaces of a fuel tank when a car parked in a warm, indoor space with a small amount of fuel in the tank. The less fuel is in the tank and the greater the difference in temperature, the more concentrated the solution is in the tank. In addition, water can enter the tank while refueling.

The water gradually blends with the fuel resulting in fuel pump failure and the spark plug. Diesel and nozzle encounter this problem more often. Condensate water leads to freezing fuel hoses and diesel main filters in winter.

Unstable operation of the engine: The rotation will be unstable, the operation of the engine will be jerky, especially on raw sugar with fuel tank is not full.

Can remove water from the fuel tank and fuel system on all special substances to remove water from the fuel tank.

Hard start of the diesel engine

  1. Hard start of the diesel engine heats up as opposed to the easy cold start may be due to the high pressure fuel pump fault that is connected to the plunger brace. As the fuel heats up, its viscosity decreases and hydraulic loss increases. In this case, the plunger can not generate enough pressure to open the nozzle during engine startup and the fuel is not moved into the combustion chamber.
  2. In the modern diesel engine failure of warm boots can be connected to the failure of the sensor of the nozzle operation. One of the engine nozzles is equipped with a temperature sensor motor. When the engine starts to cool, the sensor commands the injection angle change and fuel the fuel in the filter (if the engine is equipped with such a system). If the sensor is broken, it will give the same command with warm startup as when cold startup. As a result it leads to overfueling, the appearance of steam locks in the fuel stream and engine startup is difficult.

Diesel fuel froze, difficult start of the diesel engine at low ambient temperature

  1. Application of diesel fuel does not correspond to seasons or climatic zones, and also applies diesel fuel that does not meet performance standards (high paraffin content). The reason for freezing diesel fuel is the presence of paraffin (paraffin) hydrocarbons. At low temperature paraffin starts to crystallize. As a result, diesel fuel thickens and gets viscous. The smallest crystals of paraffin clog the fuel filters, accumulating in pipes and blocking the distribution of fuel to the bottles.
  2. Presence of moisture in diesel fuel. The humidity in diesel fuel can cause the failure of the fuel delivery to low-temperature motor cylinders. At the positive water temperature and the emulsion formation fuel destroys the filter cartridge of the main filter, and at freezing temperatures the ice crystals block the fuel filters.
