So if somebody could help out with some info.
1. What is the Fuell Pressure from the pump. I was told 4 Bar. But when I checked I only got 45 PSI which is normal for most EFI bikes.
2. What is the injector flow rate. in cc per min ?
Hello Chinoy (Ron),
1. In my previous post I had mentioned about the pressure as per service manual in this thread, 2.9 bars = 42 psi.
2. I could not find injector flow rate in manual but got thinking about it. Here is my take on it. The flow rate is approximately 63 cc per minute at 60 mph speed.
I have calculated this value theoretically as follows - My G5 (same engine as C5) gives me 70 miles per gallon. That means if I ride my bike at a speed of 70 mph it will cover 70 miles in one hour and consume 1 US gallon of gas in that one hour. Since US gallon is 3.78 liters, that is 3780 cc consumed in one hour. Thus gas consumption is 3780 cc divided by 60 minutes = 63 cc per minute. The injector must at least supply this much gas.
There are three assumptions in this calculation - First assumption is that there is no loss of gas anywhere and all of it is used to give me the distance travelled - Second assumption is that this value is at a certain rpm of engine (equivalent to 60 mph - the speed at which I got my mpg) - and the Third assumption is that there is not a significant difference in the flow rate from 60 mph to 70 mph.
At idle the flow rate must be less than that.
