Cars Losing Gas: Causes And How To Fix It

Causes and ways to fix the car without gas

In the process of using a car, short of gas (short of breath) is a very common situation. This phenomenon is annoying for users: greatly affects the operating power as well as the inherent acceleration of the vehicle. So why do cars have this problem? Is there any solution to deal with it?

In fact, the lack of gas in cars comes from many causes, with each cause also having a way to fix it. For better understanding, same Thanh Phong Auto post tracking.

Causes Of Car Slowing Down And How To Fix It.

Low Cylinder Pressure

In order to provide enough energy for the car to operate smoothly, the engine must have a large enough pressure in the cylinder to ensure a fast and stable fuel combustion. If the pressure level is low, it will affect the engine power, when the car goes uphill or accelerates, it will lose the gas and may not step on the accelerator.

Low pressure level affects engine power

How to fix: check the pressure in the cylinder before driving, provide enough pressure to ensure the car operates stably.

Fuel Filter Blockage

The fuel filter is located between the fuel pipe and the injector, which has the function of screening impurities and dirt in the fuel before being consumed in the combustion chamber. In case this part is blocked or damaged, the engine will not be refueled with enough fuel and will cause a gas shortage.

How to fix: clean and maintain the fuel filter periodically. If damaged or torn, it needs to be replaced.

Air Filter Problem

The path of the air to the combustion chamber passes through the air filter. The air filter has the role of screening dirt and impurities - cleaning the incoming air source. If this part fails, dirt mixed in the air will enter the engine, causing the car to lose gas.

How to fix: periodically check and change the air filter to limit dirty air into the combustion chamber, helping the vehicle maintain the power to operate smoothly.

Congested Exhaust

Another cause that also causes cars to run out of gas is that the exhaust gases from the combustion of the engine cannot escape, causing blockages and affecting engine power. Exhaust gas blockages can be caused by malfunctioning exhaust ducts and catalytic converters.

  • Exhaust gas pipe: if it is distorted, the exhaust gas will not be able to circulate.
  • Catalytic converter: If it is overheated or damaged, the exhaust gas will be reduced in ability to circulate, causing back pressure in the combustion chamber and affecting engine power.

How to fix it: take the car to a professional service center to have it checked, repaired or replaced.

Malfunction Sensor System

Car sensor system usually include oxygen sensor, camshaft sensor and intake air flow sensor. Sensors transmit information to the ECU to accurately calculate the level of fuel and air supplied to the combustion chamber. In case the sensor fails, the information received by the ECU may be wrong, making the combustion efficiency not high and causing a gas shortage.

How to fix: Take the vehicle to a service center to check the sensor and replace if necessary.

Broken Camshaft Belt

The camshaft belt (belt) is an important part to connect the crankshaft and the camshaft flywheel to help them work together. Over a long period of use, the camshaft belt can be worn and slippery, affecting the synchronous operation of the crankshaft and camshaft, and reducing the efficiency of the ignition process. This situation can also be the cause of the car's engine not operating stably, easy to happen gas.

Camshaft belts can wear out, reducing ignition efficiency

How to fix: replace the camshaft belt, install it correctly to ensure the synchronization of the crankshaft and camshaft.

It can be seen that, in most cases car is out of gas must take the car to check, replace damaged or clogged parts. Therefore, if the car encounters a shortage of gas, the car owner should take the car to a professional garage to be checked, determine the right cause and fix it in the right direction. Avoid leaving this situation for too long to affect the driving experience, causing danger when the car does not accelerate as expected.
