Before the Second World War, jet engines were being tested in labs. Their compactness and great power made them a perfect fit for airplanes. With the help of an American physicist, Hans von Ohain, a young German physicist,...

In 1948, Pratt & Whitney developed a jet engine with two compressors. The outer compressor provided high compression for performance while the inner compressor provided power to the turbine blades. These engines were first...

During the initial development stage, the first components of a jet engine are made, but it can take up to two years before they are completed. Once the initial design phase is complete, the next phase is the development and...

Using a jet engine in flight requires the use of fuel that burns at high temperatures. The fuel ignites air and the resulting explosion expands the air mass. The same air mass then exits the engine and the new, larger air mass...

A diesel engine is an internal-combustion vehicle engine. It uses compressed air and a high temperature to ignite the fuel, and this combustion then actuates a piston. This process transforms chemical energy into mechanical...

The diesel engine is an internal combustion engine that produces energy from fuel. To produce this energy, the air must be heated to a temperature higher than that needed to ignite the fuel. Typically, this temperature is around...

The diesel engine has undergone several changes over the years. Initially, the engines were simple, and they were used in tractors. These days, they are generally more complex and have variable geometry turbochargers, so the...

The diesel engine is a powerful and efficient internal combustion engine used in a variety of vehicles, trucks, and construction equipment. This fuel-efficient design is ideal for low-cost operations, because the compression...

The diesel engine is one of the most powerful engines available. Its torque can rival a gasoline engines, and it’s much lighter than its gasoline counterpart. Modern diesel engines also have a lower carbon footprint than...

In the past, the primary goal of vehicle makers was to make a better horse. Then, they focused on a more practical vehicle that would be more environmentally friendly. Then, their goals shifted to luxury, speed, and power. This...

A hybrid engine is a powertrain with a combustion engine and an electric motor that work in tandem. This allows it to generate more power than a traditional vehicle without sacrificing performance. Some hybrid vehicles even have...
