Gasoline

Gasoline

Many types of fuels and lubricants used in vehicles.
Some of them contain chemicals that are toxic and flammable and must be handledwith care.
Be careful if the fuel or lubricant, a type that is not suitable for use by accident, can cause serious damage to the part-a part that works.
It is important to know the different types of fuels and lubricants.


FUEL

         The fuel used by today's vehicles contain gasoline and diesel (diesel) and methanol, LPG and other fuels.
Here we discuss two types of fuels: gasoline and diesel.


NOTES:
Change of fuel over time.


GASOLINE

   Gasoline is a mixture of hydrocarbons produced from refining crude oil.
Gasoline is very volatile, and generate high heat.
And, gasoline also meets the necessary conditions for vehicle fuel:
.Does not contain hazardous materials.
.Anti ngelitik (anti-knocking).
.The price is quite low.


For these reasons, the gasoline used as fuel for gasoline engines.


WARNING:
Gasoline is very volatile, and transformed into a flammable gas when in contact with air.
Because gasoline burns easily with just a little spark and become very dangerous,so be careful when handling.


THE OCTANE NUMBER


Octane number is one of the gauges to show the characteristics of gasoline and fuelrepresent the characteristics of anti ngelitik (knocking).
Gasoline with higher octane number has a small chance to cause the engine ngelitikcompared with a lower octane gasoline framed.


To raise the octane number, some types of gasoline containing lead, while othersunleaded.
Because some machines are designed to use gasoline that contains lead, while others without a lead, then it must use the right type of gasoline.


INSTRUCTIONS:
Ngelitik (knocking) is generated by burning gasoline that is not normal in the cylinder. The sound is caused by the repetitive beats on the cylinder wall, which reduces engine power output.




DIESEL FUEL

   Diesel fuel (sometimes called "light oil") is a mixture of hydrocarbons are distilledafter gasoline and kerosene refined from crude oil at a temperature between 150 to 370 º C (302 to 698 º F). Diesel fuel is mainly used to run diesel engines-meisn.


CAUTION:


Unlike gasoline, diesel fuel also serves as a lubricant.
Do not swap the fuel, because when petrol put in diesel engines, incidentally, will be able to damage the injection pump and nozzle.


Diesel fuel is classified into various types, mainly depending on the level of liquidity,because liquidity levels will decline, when the temperature is low. The type usedshall be in accordance with (temperature) environments.


CETANE


Cetane number is the capacity of the combustion of diesel fuel.
The higher the number the better the ability to burn and the least occurred ngelitikengine (knocking).
The minimum cetane number of fuels that can be used in high-speed diesel passenger cars are usually 40-50.


NOTES:
Stroke occurs when the diesel engine be long before the time of combustion(ignition delay), as if the fuel cetane framed in temperature or low engine speeds. If the interval before ignition, the greater the fuel in the cylinder is left to burn orexplode, causing the pressure to rise suddenly. This corresponds to a whistle.

fuel injectors

Routine service injection engine can be focused around the fuel supply system and air.One consideration view the quality of fuels in the ground water is uncertain. This step should be done regularly every 5,000 miles. The main components consist of the fuel filter, air filter, fuel pump, throttle body (skepticism injection) and nozzle / injector. Five sections were determining the viability of an injection system.

FUEL FILTER Treatment begins from the fuel filter. "We never know the condition of the tank is dirty or clean, especially for cars years old, so it's clean fuel filter with the help of high-pressure wind. Generally these components are located in the brackish and made of metal. If it is too dirty, should be replaced. If allowed to continue, the damage could spread to the petrol pump. The indicators, noise with tone was stable. "Injection pump is very expensive, so it should be painstaking care.

Fuel injector nozzle spray nozzle must also be cleaned. This means that the direction and shape of the ideal spray. Low quality gasoline which causes holes whose size is very small nozzle clogged crust / dirt. Spray gasoline so chaotic and debits decrease.As a result, the engine turns limp and pull mberebet. No need to disassemble the nozzle, simply mix the chemical solution into the gas tank cleaning. Petrol and chemical solution bersenyawa and this will flow into the nozzle to scrape dirt. In the market many products that are useful for that. Do it regularly so no need to replace the new nozzle.

Skep throttle body injection or throttle body (TB) is also susceptible dirty. Symptoms, the pull is less responsive. Even if the dirt had accumulated on the TPS (Throttle Position Sensor) can cause limping round meisn when stationary. Source of impurities from the air that is inhaled into the baker. Therefore, cleanliness of TB depends on the maintenance of air filters. Clean the TB using a liquid spray is sold in auto parts store / tooling. Select recommended for injection machine. You do this by spraying through the mouth while the machine is turned on TB skepticism stationary. Keep the engine speed so as not to die, so that cleaning fluid can get into the gap skepticism. This process also functions to clean the baker. Spray cleaners cairna a tin then turn off the machine about 10-15 minutes. Continue to turn the machine back and play high-rpm engine rev up to 6000-6500 rpm). The remaining dirt or crust on the TB and the baker will be wasted space with exhaust fumes. If the machine is equipped with sensors that control air flow, do not loose the intake tract. Spray the cleaner through the air hole (breather) in the intake tract. Next follow a similar procedure on machines that have no air flow sensor.After that, check the air filter so that the cleaning step TB and baker no redundant space. Clean with a high-pressure air from the back or exchange if it was too dirty. "Try to use original pasrts order flow (flow, ed.) Nice air.

Set CO No less important, do the setup process of CO (carbon monoxide) as the closing sequence of this mild treatment. Take advantage of engine analyzer tool as a gauge. This measurement aims to understand the process of combustion in the engine, whether it is efficient or not. CO ideal value should be below 1 percent. If the sodium absorption ratio, do the reset in the gasoline supply system, air and ignition.
