Diesel engine patent

In 1893, Rudolf Diesel received a German patent for the diesel engine. His engine burns fuel oil rather than gasoline, and uses high compressed of the gases in the cylinder rather than a spark to ignite the fuel. Diesel engines were used widely in Europe for their efficiency and power, and are still used today in most heavy industrial machinery. Diesel cars never caught on in the U.S., partly because the diesel engine's greater efficiency is counter-balanced by its higher emissions of soot, odor, and air pollutants. However, some environmentalists argue that in spite of the diesel engine's exhaust pollution, its fuel efficiency may make it more environmentally sound than the gasoline engine in the long run.

Benefits of the Revival

After the revival had concluded, the three pastors were discussing the results with one another.

The Methodist minister said, "The revival worked out great for us! We gained 4 new families."

The Baptist preacher said, "We did better than that! We gained 6 new families."

The Presbyterian pastor said, "Well, we did even better than that! We got rid of our 10 biggest trouble makers!"
