Enough so that you can actually run an automobile engine on CO. Here in Finland, during second World War when petrol/gasoline was in very short supply, even army vehicles would run on CO gas. Petrol was only used for starting the engine. Starting a truck involved first chopping little pieces of wood to a reactor attached to the car or lorry, lighting them and creating a fire with suitable under-supply of oxygen so that the reactor emits CO. When the gas is at right concentration to burn, start then engine with petrol and then switch to CO gas. This is El Kamina, a modern hack made by the current Prime Minister in the country: http://jalopnik.com/el-camino-driving-jalopnik-endorsed-badass-elected-lea-1699009361 http://jalopnik.com/el-camino-driving-jalopnik-endorsed-bada... Regarding its emissions, don't ask. Also, don't bother about burnout contests, it is not very powerful. But it runs on renewables.
