Nice article but it did have a few mistakes. The article below is a nice addition to the idea.
In practice, Diesel was not able to keep up with Carnot’s perfect thermodynamic theories, but they put him on the right track. Even though Diesel’s compromised engine only had a 13:1 compression ratio, it was enough to break him free of the fuel-limited ratios plaguing gasoline engines. He also accepted his engine would need water cooling. Another setback had to do with the high-pressure fuel injection system, which did not work as intended (it took 30 years before a system like this came into existence-in the interim diesels used air injection). By 1895, Diesel’s test engines were producing 25 percent thermal efficiency.
