Fuel System (Gasoline)
After a bit of tweaking the brain-’76 Civic sedan, I somewhat understand the system flow of gasoline from the tank to the carburetor. Several times, the problem occurs in the flow of this gas. Halt the flow of gasoline into the carburetor, so the car’s engine suddenly died while driving, lit more difficult, but gasoline in the tank is still oke. There is what the hell? Following discussion on fuel systems using gasoline and its potential problems that may arise in the system.
If it runs out of gasoline in the car, the engine will stop as well of course not? Likewise, if the channel is not smooth gasoline, the rate of the machine will also be hampered.
Gasoline used as a fuel source in the ignition to drive a piston and subsequently followed by a shaft rod to rotate the crankshaft. On the 4 stroke engine, the process is the successive suction (intake), compression (compression), fuels (power) and exhaust (exhaust). Gasoline will go from the carburetor when the suction process, which in turn will be burned after compressed to generate power to drive the engine.
Well, prior to combustion, air and gasoline must be mixed in advance so that the shape of mist (gas). This is where it takes a system, ie the fuel system. Components in these systems respectively are as follows:
1. gas tank
Serves to keep inventories of gasoline that will be channeled into the combustion system. There is rarely a problem in this component
2. fuel filter
Serves to filter the gas before it is sucked by the pump and routed to the carburetor. This component has two channels: the inlet (in) from the tank and outlet (out) to the pump. Do not install the wrong yah. The problem that often arises is the filter is old, so dirty and can clog. Function only as a filter, so the filtered dirt can settle in these filters. Often a dirty filter will disrupt the flow of gasoline. I never experienced it, the engine suddenly died, several times the new distarter can walk again. If dirty, it can be cleaned or replaced. Cheap, at only 20,000 Tegal
3. gas station
Serves to suck gasoline from the tank and passes into the carburetor. Intensive well if the pump is not functioning properly. I use an electric fuel pump in which there is winding wire (coil) and requires a voltage of the battery. Similar to the aquarium filter water pump. Two problems that often arises is do not get a voltage pump and pump wear. Voltage supplies are often interrupted normally if a fuse in the fuse box loose or even broken. Dirty filter also makes the pump work harder. If the problem persists, replace aja, but pretty expensive (I’ve bought Rp.140rb, but there is a cheaper type it).
In the saloon car, pump and fuel filter is usually located under the left rear seat.
4. carburetor and air filter
Carburetor serves to mix the air (which has been filtered by air filter) and gasoline to produce a mixture in accordance with the engine working conditions. Carburetor itself consists of mixing chamber and float chamber. In the mixing chamber there is a venturi, nozzle and the gas valve, whereas in space there is a float valve needle and float. The principle works is when the piston is in complete suction and gas valve is opened, filtered air into the cylinder through a venturi. In the area of the venturi, the air will lower pressure than the float chamber, so that the gasoline from the float chamber will flow into the venturi through the nozzle. Then the petrol and air mix to form a mist, and flowed into the ignition cylinder through the intake manifold.
The problem is often so clogged nozzles. Try the carburetor on the service is occasionally lightly to be cleaned and reset. Servicing fees for servicing light in Cimahi is Rp. 40-60ribu’s.
5. intake and exhaust manifolds
Gasoline and air are mixed in the carburetor is channeled into the ignition cylinder through the manifold in (intake), whereas the rest of the exhaust gases expelled into the exhaust pipe (and subsequent exhaust) through the exit manifold (exhaust). There is rarely a problem with this section, unless the gasket is sometimes worn, especially at the manifold gasket out which resulted in smoke there’s a leak, not all removed by exhaust
Above has been discussed about the fuel system components. Now if in the middle of the road, our car suddenly breaking down like out of gas, could be a source of problems exist in this system. All you need do is try to check whether gas can flow into the carburetor. The trick, the contacts in position on (engine off) so that the gas station will pump gasoline into the carburetor. Open the gasoline in the carburetor inlet, petrol should be flowing. If dry, then the problem is in the pump or fuel filter or even gasoline OUT. For the case of gasoline runs out, the pump will sound louder beats.
