Measurement of actual CO2 mass emitted from a diesel engine for gas emission monitoring

[AEW]

I was wondering if there is a method to measure the actual total mass of carbon dioxide (CO₂) emitted from a diesel engine used with a generator for power generation (Caterpillar 3512B). Infrared CO₂ sensors, such as ENMET EX-6165 sensor, generally measure the gas concentration in parts-per-million (ppm), describing the amount of gas by volume of the air at a certain time and location, which is not what I am looking for in this application. Liquid flow sensors are already installed in the diesel fuel supply and return lines to determine the amount of diesel consumed, and hence the amount of carbon burned and CO₂ created, but I am looking to correlate these measurements with actual measurements of CO₂ mass produced at the output of the exhaust system.

The question can be formulated as how to measure the CO₂ emission rate from the engine exhaust system. A typical solution in practice would be to find a dedicated gas flow sensor and a monitoring system that accomplishes that.

Any idea on how to approach this problem would be greatly appreciated.

Thanks.
