Diesel engine with 45% efficiencyThe very high efficiency of modern Diesel engines is much mentioned., but this high efficiency is only reached in a small area of operating conditions.
On the highway would be 9.6 l/100km at 170km/h a very good efficiency, but I roll here in the 1. gear in a traffic jam. 9.6 l/100km for 9km/h. Makes about 5.3% efficiency. |
