Under What Conditions Do Cars Emit the Most Carbon Monoxide?

[NatalieLee]

The highest emissions of carbon monoxide occur when the engine is idling while parked. Principle: The combustion chamber of a car engine is more prone to producing carbon monoxide when operating at high temperatures. When idling while parked, there is no load, and the fuel burns without performing work, causing the combustion chamber temperature to remain high, thus making it easier to generate carbon monoxide. Here are some methods to reduce car emissions: 1. Turn off electrical appliances after exiting the car: including the radio, air conditioning, and window heating systems. 2. Proper tire pressure saves fuel: Insufficient tire pressure shortens the tire's lifespan. Tests show that maintaining the manufacturer-recommended tire pressure can reduce fuel consumption by approximately 3.3%. 3. Accelerate gently: A comparison between sudden acceleration and gentle acceleration at the same speed reveals a difference of up to 12mL in fuel consumption, resulting in an extra 0.4g of CO2 emissions per kilometer.
