Engines - Cars

The engine or motor is a machine designed to convert energy into useful mechanical motion. Explained in a simple way, the engine is a mechanical device that converts force into motion. Engines change heat into mechanical movement in many ways. The most common type is the internal combustion engine which typically burns fuel and oxygen, which forms hot gases to generate energy.

Different types of internal combustion engines may use different types of fuel such as gasoline, diesel fuel, gas, methane and kerosene. Increasingly common are electric motors in modern automobiles. With this type of motor, electricity is converted into mechanical motion through different electromagnetic fields.

In diesel engines, there is less torque and more fuel consumption. It is important to know that one of the first engines was tested and developed in France in 1807 by de Rivaz and brother Niepce. The first 4-stroke gasoline car engine was created and designed by Karl Benz. In 1896, Karl Benz patented the first engine with horizontal movement of the pistons.

The first diesel engines were only used in trucks and buses, while in present day, diesel engines are used even in small urban cars. Prolonged use of internal combustion type engines has given their makers time to develop and improve them by adding on-board computers, which helps in the operation of the motor. Added turbochargers increase the power and efficiency of the motor. Motors can have from 1 to 16 cylinders.
