l.The person that I interviewed was my dad. When I interviewed him he told me that Rudolf Diesel was German and that he built cars with his engines in them and then other people started using the engines and his name for his engine became famous. Rudolf Diesel was one of the more important inventors during the industrial revolution. He told me a lot about the way that the engine works. The diesel engine has no spark plugs, the engine just squirts some fuel in the cylinder and the air pressure causes the piston to go down and that in turn makes the pistons go up and down. One of the unique things about a diesel engine is that you can use low grade fuel and the engine will run the same. The diesel engine actually runs cleaner than a regular gasoline engine. The engine will not rev up very fast but when it gets revved up it will run all day with no problem. The engine is very heavy compared to the power it produces but when it gets running it runs smooth and can run almost forever. The engines are more expensive at the start then a regular gas engine but when you see how long the engine will run and that it gets good running time to how much fuel it uses then it makes up the money in the long run. One of the reasons that the engine is used in big trucks is that it has a lot of torque but not very high top end speed. The diesel engine uses its own kind of fuel and is some times cheaper then regular gasoline. The reason that it is sometimes cheaper is because you don’t have to have it as clean and refined as regular gas. That is what I got out of the interview about Rudolf Diesel and how the diesel engine works. ...
