The main purpose of an engine is to convert energy into mechanical motion. However, the basic initial engine has evolved due to the evolution of automotive technology and nowadays we can speak about various types of engines, each sharing the same purpose but using different means. The main types of engines are the traditional gasoline driven internal combustion engines, the rotary engine, hybrid vehicle engines and various alternative fuel engines such as the ones found on solar cars, hydrogen fuel cell cars, so-called plug-in hybrids and fully electric vehicles
Internal combustion engines are the type of engines used by the vast majority of cars. Most of them use gasoline as fuel to produce the power stroke that drives the car. The principle behind the internal combustion engine is the series of small explosions it creates in order to use the power developed to the drive-shaft via a transmission. There are several types of internal combustion engines but the four-stroke engines are the ones which are mostly spread. As their name implies, four-stroke internal combustion engines function following four distinct procedures: intake, compression, ignition and exhaust.
Diesel engines are a particular class of internal combustion engines which use diesel fuel in the process. They are considered to be more efficient that the ones which use gasoline and they are more environmental friendly as the carbon emissions are fewer that stirling engine for sale in the case of the gasoline engines. Diesel fuel is usually obtained from distilled petroleum; however, there are certain bio-diesel fuels which have been produced using vegetable or animal fats. A diesel engine mixes the fuel with hot air in order to make the engine function, unlike gasoline engines which use a spark plug.
There are several hybrid vehicle engines nowadays which combine an electric motor powered by an on-board gasoline engine and which are supplied by battery packs. These types of engines are very efficient, they use less fuel than any other type of internal combustion engines, whether gasoline or diesel, and are Eco-friendly, as the emissions are considerably reduced.
For those interested in Eco-friendly engines, one should look for vehicles equipped with alternative fuel engines, which can be solar cars, hydrogen fuel cell cars or fully electric vehicles. These types of engines are still not very widely spread, although they are efficient and do not harm the environment. Some of them are still not available to the public, being just prototypes. Therefore, the largest classes of car engines remaining are gasoline- or diesel-powered engines, all specially designed for specific vehicles, from automobiles to vans. Owning a car is rather common, a van is not always at hand but it can prove to be rather important. Therefore, one can opt for van leasing as a money saving tool and choose between micro vans, small vans, mid vans, large vans, pickups or 4x4s, whether gasoline or diesel powered cars, depending on the purpose the van has to serve.
