Pistons moving,

Engine powering,
Vehicles moving,
Exhaust escaping,
Now we ride!

 
2     A voyage into the center of an internal-combustion engine would be a fascinating journey. What you would see is many parts joining as one to achieve the ultimate goal- the movement of vehicles and machines. Diesel and rotating engines are two types of internal-combustion engines.
 
3     German engineer, Rudolf Diesel invented his engine in 1892. His engine was first designed to use coal dust as fuel. Diesel engines today use low cost heavy petroleum to produce energy for vehicles and machines. Most internal-combustion engines use electrical sparks from plugs in the cylinders to ignite an air-fuel mixture. Diesel engines use the compression or squeezing of air in the cylinder to ignite the air-fuel mixture when it enters the cylinder. Once the mixture is ignited, the combustion or burning of the mixture produces the energy that powers the pistons which in turn move the car forward.
