Hello research community,
I got CFD simulation results of an internal combustion engine regarding emission in kg unit. For example: 14.5 gram of CO per cycle.
I need to convert this number to g/kW-hr to compare it with standards.
Anyone has any ideas?
You can convert it if you have records about energy produced per cycle. It is the ratio CO (grams)/ Power (kWh) multiply be 1000.
The first question I have: When you say 'cycle' are you talking about one engine cycle, say power stroke to power stroke (assuming a piston engine) or some kind of drive or operational cycle where say the vehicle is driven over a 5 mile course? The approach is the same but you have to start by figuring out how much energy (power * time) was produced in your cycle.
First you need to know the engine operation speed and then can convert the per cycle value into the speed. Then calculate the power produced at that speed and load. Then its straight forward to convert into g/kW-h.
To convert the emission value from grams per cycle (g/cycle) to grams per kilowatt-hour (g/kW-hr), you need to know the power output of your internal combustion engine in kilowatts (kW) and the number of cycles per hour.
