What is the cause of engine gasping?
2 Answers
Engine gasping is primarily caused by carbon deposits. Additional information: 1. Use high-quality fuel. Since the main components of carbon deposits are wax and gum deposits from fuel, it is best to use fuel with as low gum content as possible. While you cannot change the quality of the fuel, avoid adding cheap fuel of unknown origin. 2. Avoid prolonged low-speed driving. To prevent carbon buildup, periodically drive at high speeds. The principle behind high-speed driving to remove carbon deposits is to increase gas flow velocity, which can remove some loosely attached deposits, and to raise combustion temperature, burning off some carbon deposits in the cylinders. 3. Add fuel additives to the fuel tank. Using regular fuel additives with cleaning effects over the long term can also help in removing carbon deposits.
I've been driving for decades and have encountered engine hesitation several times. It's usually due to issues with the fuel system, such as the fuel pump not delivering fuel smoothly or a clogged fuel filter causing unstable oil pressure. It could also be a fault in the ignition system, like weak sparks from aging spark plugs leading to inconsistent cylinder ignition. A blocked air intake system can also cause hesitation; a dirty air filter can choke the engine. Once, my car hesitated on the highway, and upon inspection, it turned out to be clogged fuel injectors, which were fixed by cleaning. This can increase fuel consumption and may even damage the catalytic converter, so when you notice it, slow down immediately and check the dashboard for any warning lights.
