But things get even better with gaseous fuels like propane, natural gas and hydrogen. These can run much leaner, (30:1 for propane IIRC and even leaner for hydrogen) and practically not even need a throttle valve. Just enrich the AFR for more power, like in a diesel.
Seems only common in theory, all but non existent in practice.
