What is the mixture ratio?
2 Answers
Mixed gas ratio is Ar80%, CO220%. More details about the mixed gas are as follows: 1. Introduction: Mixed gas (gas-mixture) refers to a gas containing two or more effective components, or non-effective components exceeding the specified limits. It is a mixture of several gases commonly used as working fluids in engineering. Mixed gases are usually studied as ideal gases. 2. Characteristics: The air content is less than the theoretical air volume, making it impossible for the fuel to burn completely. The combustion products generated inevitably still contain combustible substances.
As a seasoned veteran who has run a repair shop for years, the air-fuel mixture ratio essentially refers to the proportion of air to gasoline. The standard for gasoline vehicles is 14.7 parts air to 1 part fuel, ensuring smooth and efficient engine combustion. If this ratio deviates—for instance, too little air making the mixture 'rich'—you might notice heavier throttle response, higher fuel consumption, and black smoke from the exhaust. Conversely, too much air making it 'lean' can cause engine misfires, loss of power, or even stalling. Maintaining this ratio is crucial for daily driving. Older vehicles are prone to imbalance due to faulty oxygen sensors or clogged fuel injectors, which can be diagnosed by reading trouble codes with a scanner. Regular maintenance, including checking the oxygen sensor and throttle body, is key—don’t wait until the car breaks down to act. Different fuels like ethanol-blended gasoline may have slight variations in ratio, but overall, the principle remains largely unchanged.
