What is the fuel injection system in a car?

Fuel injection system - a fuel supply system installed on modern gasoline engines to replace the outdated carburetor system. Engines with this system are called injector engines. In the injector system, fuel injection into the airflow is performed by special injectors located either in place of the carburetor (intake manifold)…
Glossary

What is gas pedal?

This is the name of the special flap through which the fuel and air supply to the combustion chambers of the cylinders is regulated. This flap is directly connected to the accelerator pedal and by pushing it you can regulate the pressure in the cylinder block. How does a gas…

What is a fuel injector?

Nozzle (another name - injector), being a structural element of the injection system, is designed for metered fuel supply, its atomization in the combustion chamber (intake manifold), and the formation of the air-fuel mixture. Nozzle is used in the injection systems of both gasoline and diesel engines. Modern engines are…

What is power steering?

The power steering - is a system consisting of a pump and hoses to make it easier to turn the steering wheel. The power steering is especially helpful when turning the wheels on a stationary car and with low-profile rubber, because in this case the "contact patch" of rubber with…

What is an onboard computer in cars?

The vehicle onboard computer is an electronic system that displays both instantaneous parameters (current time, vehicle speed, engine speed, engine temperature, interior and exterior temperatures, remaining fuel in the tank, onboard voltage, etc.) and diagnoses malfunctions of vehicle systems. How the car engine control unit (EUC) module controls and works

What is a shock absorber?

Shock absorber - friction device of the suspension of land vehicles, which converts mechanical energy into thermal energy. It serves to attenuate shocks and vibrations, as well as damping body oscillations. According to the active substance shock absorbers are divided into oil (hydraulic), gas and combined; by the action -…

What is Engine Oil Volatility?

Volatility is the property of the lightest fractions of the engine oil to evaporate at high temperatures, which is expressed as a percentage of loss from evaporation after heating the engine oil for one hour at 250 °C. To determine the vaporizability, or volatility, of motor oil, the Knock method is…
Glossary

What is ACEA oil classification?

ACEA standard ACEA is an association of European automobile manufacturers. The first letters of the ACEA standard indicate the class of vehicles for which the oil brand is intended. A/B - oils for gasoline and diesel engines (before 2004 A - auto oils for gasoline engines, B - for diesel…
Glossary

What is synthetic oil?

Synthetic oils - unlike mineral oils, these oils are produced by chemical synthesis. Synthetic oils typically have good viscosity-temperature dependence, weak oxidation tendency, low freezing point, high-temperature stability, and good resistance to chemical agents. Synthetic base oils are oil-like synthetic liquids (polymers or oligomers) obtained by synthesis from different monomers.…
Glossary

What is multigrade oil?

Multigrade oil - is an engine or gearbox oil that meets a wide range of SAE viscosity grades and is, therefore, suitable for summer and winter use without oil change at the intervals recommended by the manufacturer. Explanation of Viscosity and Multigrade Oils - Video
