Ship’s engines as propulsion

Most ships that we see today are built with diesel engines as the primary propulsion. The built-in diesel engines are coupled with the propellers from a through a gearbox. Today, the most manufacturers of diesel engines are seen to come from the manufacturers Caterpillar, Cummins and Detroit. In addition to the large international manufacturers, there are also Danish manufacturers of diesel engines.

The Danish manufacturers that are also available are Alpha, Bukh, Grenaa and Callesen. Furthermore, manufacturers such as Deutz, MWM, Volvo, Scania, Wartsilä are very popular marine diesel engines. In addition to popular marine diesel engines, there are also popular manufacturers within gearboxes for ships. The manufacturers Twin Disc, Volda, Liaaen, Pay & Brinck, Lohmann & Stolterfoht and Reintjes can be mentioned here.

The two most well-known diesel engines are the otto engine and the diesel engine, both of which are named after their inventors, Rudolf Diesel.

An engine works by utilizing the energy in the petrol that is being filled and then converting the energy into movement and heat. This propulsion is used, among other things, for large machines and means of transport such as ships, cars and planes.

An engine works by adding a cylinder in which a piston will move up and down between two points. These two points are also called top dead center and bottom dead center. In large marine diesel engines, the push rod was replaced by another element, namely a hydraulic transmission in the movement.

How does a gearbox work?

In order to understand how a manual gearbox works exactly, it is important to know that all gears are connected individually, but not locked to the shaft to which they have been attached. Each gear is engaged for each shift, which with a manual engine happens when changing on the gear stick.

The automatic gearbox has become more complex and theological today and is therefore equipped with many small details. Furthermore, the modern gearbox and engine have become more climate-friendly and thereby emit less CO2. Therefore, it is also important that the modern gearbox and engine are sent for service more frequently than before.

But where does the automatic gearbox come from? Today, there are many different stories and opinions about where exactly the automatic gearbox originated and who invented it. This is because the Germans believe they have evidence that the modern gearbox dates back to the marine industry back in 1890. However, it was GM’s engineer Earl Thompson who was the first to put the automatic gearbox into mass production. This gearbox is the one we see today in many cars and has the same production method.

This invention by GM’s engineer Earl Thompson is considered one of the most important inventions within the automotive industry. The first automatic gearboxes that came into the world were invented with only 3 forward gears and one reverse gear. When you had to put the car in reverse gear, you had to switch off the engine and start it up again afterwards, and only then could you put the car in reverse gear.

Today we must be very happy that the automatic gearbox has become somewhat better and more technologically modern. This is also one of the reasons why the modern automatic gearbox is often seen in modern cars.
