Heat dissipation principle of automobile engine
The power source of the automobile engine, the engine is a kind of transformation of energy into mechanical energy of the machine. By using the modern automobile engine is an internal combustion engine is the internal combustion engine, the chemical energy of the fuel into heat energy and then convert heat energy into mechanical energy of the machine, and the energy conversion process is carried out in the engine the interior of the cylinder. Internal combustion engine used on the car include gasoline engine and diesel engine.
The engine is a complex machine composed of many institutions and systems. Either gasoline or diesel engine; either the four stroke engine and two stroke engine; whether it is a single cylinder engine, or multi cylinder engine. To complete the conversion of energy, realize the work cycle, ensure the long time continuous normal work, must have the following some institutions and systems.
According to the internal combustion engine can be divided into gasoline and diesel fuel used (Figure 1-1-1). The use of gasoline powered internal combustion engine for gasoline engine; use diesel as fuel for diesel engine. The gasoline engine and diesel engine is a gasoline engine; high speed, small quality, small noise, easy starting, low manufacturing cost; diesel engine compression ratio, high thermal efficiency, economy and emission performance than the gasoline engine.
