[SOLVED] three questions
I need an explanation for this Engineering question to help me study.
- 1- Find a current automobile that offers both gasoline and diesel options. Discuss the cost differential of the vehicles relative to the miles per gallon for a yearly use of 10,000 miles. How many years will it take to pay back the cost differential assuming $2.30/gal gasoline and $2.60 diesel.For grad students, you must pick any other vehicle besides the VW Passat, and I want you to look at 10k to 20k (1k increments) miles per year with gasoline varying from $1.50/gal to $4/gal ($0.50 increments) determine the break-even points.
- 2- Find a torque curve for a Honda CBR engine and one for aVW Passat 2.0TDI-05 (103kW). Discuss the characteristics of where the peaks occur and how these might affect vehicle performance.
3- Vehicle HVAC
Based on theoretical calculations and using the higher heating value of typical gasoline, determine the fuel needed for a 30% efficient powertrain to drive a 2000 kg vehicle 100 km/h for 4 hours at constant speed.Taking that steady speed, what are the miles per gallon and the flow rate of air needed assuming theoretical air.
