What are the symptoms of a faulty oil check valve?

The symptoms of a faulty oil check valve include extremely unstable idling or even stalling, flashing warning lights, failure to meet annual emission inspection standards, oil burning, and blue smoke from the exhaust. Below is relevant information about engine oil: 1. Introduction: Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the "blood" of the car. Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve any shortcomings in the base oil's performance, providing new characteristics and making it an essential part of the lubricant. 2. Classification: Engine oils on the market can be broadly divided into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their scarcity). Synthetic oils are further categorized into full synthetic and semi-synthetic.

Is it normal for gas to spray out when opening the fuel tank cap?

It is normal for gas to spray out when opening the fuel tank cap because gasoline is a relatively volatile liquid that evaporates into gas when exposed to high temperatures. Cars are equipped with a carbon canister system, which absorbs the gas generated by the evaporation of gasoline in the fuel tank. After starting the engine, the gas from the evaporated gasoline in the carbon canister enters the intake manifold, allowing these gases to participate in combustion in the combustion chamber. Without a carbon canister, the fuel tank could potentially explode. If the fuel tank cap were designed to be non-sealed to prevent such explosions, the gas from evaporated gasoline would be directly released into the atmosphere, polluting the environment and posing safety risks.
