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.

They’re different types of pollution. Two-stroke engines (like what’s used in leafblowers and go-karts and stuff) uses fuel the least efficiently, and releases the most harmful waste products.

Small engines are not as efficient as car engines, and do not have catalytic converters which reduce nitrous oxide pollution (which is what causes smog).

Most gas powered tools are a 2-stroke engine, whereas cars and motorcycles are generally 4-stroke. In a car engine, the cycle is SUCK fuel/air into the cylinder, SQUEEZE to compress the fuel/air mixture, BANG which is where the fuel/air mixture is ignited and pushes the piston in the cylinder down, and BLOW which is where the returning piston pushes the exhaust out into the exhaust pipe where a a catalytic converter the unburnt fuel and other compounds are turned into safer compounds.
In a 2 stroke engine, the valves for the fuel and exhaust are always open, so you’re always pushing fuel into the cylinder even on the exhaust cycle. This results in a smaller, cheaper and lighter engine, which is great for someone holding a weed eater for several hours, but not so good for the environment.
A lawn mower engine might be 5 hp and perhaps under 10 pound-foot of torque, compared to a very small car engine which might be 100 hp and about 100 lb-ft of torque. Vastly different sized engines.
