Engine power system 1.6 (16V)
Fuel is supplied from a tank installed under the bottom in the area of the second row seat. The fuel tank, filler pipe and vent pipe are made of plastic.
The connection of the filling pipe and the ventilation pipe with the tank branch pipes is non-separable. A neck is made in the upper part of the filling pipe, which is attached to the body. The vent tube is used to remove air forced out of the tank when it is refueled.
The term manifold (manifold) means "one to many or many to one". Intake manifold (also called suction manifold) serves to distribute the fuel-air mixture coming from one source (air filter), between all engine cylinders.
The engine runs smoothly only if the same working pressure is created in all combustion chambers. In order to achieve this, it is necessary that the same portions of the fuel-air mixture of the same quality are supplied to all cylinders. All portions of the fuel-air mixture must have the same physical characteristics and the same composition.
The air entering the engine is passed through the throttle chamber. All air entering the engine must be filtered.
Note. If the engine is operated without an air filter, its wear is accelerated by almost ten times!
The question is often asked, what is the purpose of the compartment, which stands on the suction pipe. The shape of this pipe was specially chosen, in order to subdue resonant air vibrations that occur at certain frequencies under certain engine operating modes. The length and shape of this pipe is chosen so that it absorbs shock waves generated in the air intake system and accumulates air, giving it back to the air stream when the pressure decreases.
The overall effect of such resonant tubes is to reduce the noise generated by the air entering the engine.
Supply system. Abstracts
1. Gasoline is a complex mixture of hydrocarbons. In order to facilitate starting the engine and achieve maximum fuel economy, additives are added to gasoline to correct its volatility in accordance with seasonal temperature fluctuations.
2. Use of low ambient temperature fuel at elevated temperatures can cause the engine to idle rough and stall due to Reid's elevated vapor pressure (RVP), associated with increased volatility of fuel grades intended for engine operation at low temperatures.
3. Violation of the normal mode of combustion of the working mixture (also called detonation combustion) leads to an increase in temperature and pressure in the combustion chamber.
5. Oxygen-containing fuels are usually a mixture of gasoline with alcohol or methyl tributyl ether, the molecules of which have oxygen in their composition - such fuels are used to reduce carbon monoxide emissions into the atmosphere.
6. Refuel the car with gasoline at a gas station where many cars fill up, and do not overfill the fuel tank with gasoline.
7. Forced crankcase ventilation system (PCV) pumps out vapors and leaking gases from the crankcase to the intake manifold.
8. The air pump of the air injection system, until the engine has warmed up, supplies air to the exhaust manifold. When the engine warms up and begins to operate under the control of the feedback control system, air is forced into the catalytic converter.
9. Evaporative emission prevention system (EVAP), consisting of a carbon filter and a series of hoses and channels, traps and traps gasoline fumes, preventing them from escaping into the atmosphere.
10. Exhaust gas recirculation system (EGR) returns part of the exhaust gases to the combustion chamber in order to prevent its overheating. The main purpose of the recirculation system is to reduce the concentration of nitrogen oxides (NOx) in exhaust gases.
11. The catalytic converter in the exhaust system stimulates the entry of exhaust gases into a chemical reaction, but does not itself enter into it. It reduces the nitrogen oxides contained in the exhaust gases, resulting in nitrogen (N) and oxygen (O2). In the second chamber of the neutralizer, hydrocarbons are oxidized (NS) and carbon monoxide (SO), which produces harmless carbon dioxide (CO2 and water vapor (H2O).
