All combustion processes will exhaust CO, CO2, and other products of combustion in some combination or other. The efficiency of the burn and the type of fuel used will determine the composition of the exhaust gases. A diesel engine, compared to a petrol engine, emits more CO2 and less CO because the combustion process occurs in an excess of air unlike the petrol engine. It still emits CO though, just in much smaller amounts. A boiler burner or diesel fired stove has a relatively crude fuel metering device compared to the injection process in an engine (whether diesel or petrol) and so will emit CO and CO2 and various other products of combustion depending on the burner design, flame cleanliness, free venting of the exhaust and combustion air supply.
