The car, as well as any car, has the main device setting it in motion is an engine. Engines which will transform energy of combustion of fuel to mechanical though there are also other types of motors enjoy special popularity.
Certainly, the motor – heart of the car or other technical device for this reason when choosing the equipment many buyers make the choice, proceeding from features of the engine, its state and working capacity.
The engine which uses diesel fuel
This option belongs to internal combustion engines of piston type. It works owing to ignition of diesel fuel because that temperature increases, and gas weight contracts. It is considered that having chosen such engine, the motorist will receive much more durable device in comparison with petrol option. But it should be taken into account that having chosen such option, qualitative need to fuel the car only. Also it is worth remembering that the diesel demands permanent care, it will be necessary to change the fuel filter and to add special additives to avoid breakage of the engine at formation of sulfuric acid.
The engine which uses gasoline
If when choosing the car the car with the petrol engine is bought, then it is worth remembering that it works, based on the preliminary compressed mix from fuel and air which then ignites from the electric spark cut in candles.
Regulation of power of such engine happens due to management of supply of air masses. Here too it is possible to allocate two subtypes of the petrol engine:
- carburetor.
- injector.
Carburetor type of the petrol engine (outdated model): this version of the engine is considered quite simple in service, but today cars with it already are practically not issued because of diseconomy and discrepancy with standards of environmental safety;
The injector engine – this engine is considered less toxic, works much more steadily. But also to such version of the engine not to do in work without quality gasoline, besides it is much more economic and the dosage of fuel in it occurs more precisely thanks to an electronic system.
The engine which uses gas
The gas version of the engine works, based on Otto's cycle. If to compare this view with the petrol engine, then the distinctive property consists in need of bigger compression of air mass.
The gas engine becomes more popular today, than petrol, and one of these reasons is big safety for ecology.
