I don’t understand how this is possible. The car engine is more efficient but the leaf blower would use a gallon or less of fuel that that amount of time as where the car would burn 30 to 40 times more that for the trip.

because co2 is not pollution, it is the goal product of perfect combustion. the car is designed to burn very cleanly and has filters and convertors to capture non-co2 products created in the cylinder. the leaf blower does not run have any pollution control and nobody cares if it is efficient or not because it does not run enough to put in that kind of effort and expense.

* A gas powered leaf blower has a different kind of engine that actually mixes the gasoline and the oil together.
* It ends up burning *both* the gas and oil.
* Car engines don’t (intentionally) burn oil.
* That’s the big difference.

Great responses so far pointing out that leaf blowers produce large amounts of particulates and smog forming hydrocarbons, but not large amounts of CO2. But no one has mentioned the main reason why- leaf blowers are generally two stroke engines. [They produce about twice as much power per pound as four stroke engines, but they exhaust a lot of partly burned fuel and even oil by design.](https://urbanemissions.blogspot.com/2009/12/2-stroke-vs-4-stroke-engines.html) This is way beyond the fact that they lack catalytic converters and pcv systems, it is inherently inefficient and dirty. Two stroke engines are restricted in most parts of the world for most purposes, but leaf blowers have to be light, so they’re exempt.

The short answer is that they burn fuel much less efficiently and because they don’t have any of the fancy filters that cars have. Because they burn less efficiently they release more harmful byproducts like carbon monoxide.
Then, There is no catalytic converter on the leaf blower exhaust like a car has. So those bypeoducts are just release into the air. Unlike in a car where a lot of them are captured by the catalytic converter

In the specific instance you’re talking about, they were looking at “unburt hydrocarbons”, or essentially fuel/oils in the air.
Due to the nature of two-stroke engines, this is a inevitable result, but in four-stroke engines, it is nearly impossible. Thus, the levels are wildly higher with the leaf blower (vs the car).
The carbon monoxide and nitrogen oxide (the more common exhaust gas measures) were nothing unexpected (much more for the car).
