Engines is the machinery, replacing one form of energy to other, in particularly kinetic. Many people believe that the engine is something artificial. But after all, and living organisms can be regarded as an engine. Our bodies - as well as engines, causing the food energy of other forms of energy.The engine is the heart of the car because creats car drives an energy. Continuously cooled engine. The car can not run without electricity, which supplies the car's battery.
Gasoline engines are more useful than the diesel that is lighter and can handle high RPM (Revolutions per minute), because race cars use gasoline engines. Most of today's cars are powered by gasoline or diesel fuel used in internal combustion engines, but these engines are environmentally friendly and are criticized for the impact of global warming. Rising fuel prices, new and stricter pollution laws, and exhaust emissions limits force to develop vehicles powered by alternative fuels. At now already produced hybrid, electric and hydrogen powered cars.
In this work I reviewing petrol engine’s concept, his parts, kinds, classification and how it work.
Lubricating (Make something slippery or smooth by applying an oily substance) – tepalinis;
Crankshaft (A shaft driven by a crank) – alkūninis velenas
Stroke (The whole motion of a piston in either direction) – taktas;
Rigid (Incapable of or resistant to bending) – kietas, standus;
Exhaust (The system through which such gases are expelled) – išmetimas;
Enormous (Large size) – didžiulis, milžiniškas;
