The overall structure of the car is basically composed of four parts: engine、chassis、body、Electric。

The engine is the power of the car，Its function is to turn the fuel entered into it and turn into a thermal energy，and convert it into kinetic energy，Drive the car through the transmission system of the chassis。

chassis ..................................

The function of the chassis is to support the body，Accept the power generated by the engine，and ensure that the car can drive normally。The chassis itself can be divided into a transmission system、Driving System、Steering system and braking system four parts。For more information about car information, please add WeChat public account: qxzyjs

body .................................

The body refers to the part used by the vehicle to carry the manned load，Also refers to the overall vehicle。Automotive body structure mainly includes seabet loginbody shells、Door、window、Performance of the front sheet、Inner and outer decorative parts and body accessories、seats and ventilation、heating、Air conditioning、Air adjustment device, etc.。It also includes cars and other equipment on trucks and special cars。

Car Electric ...............................

Electric equipment includes power supply、The engine startup system and automotive lighting equipment，In the force -ignition engine, it also includes the ignition system of the engine。

The working principle of four -stroke gasoline engine ...................

The reason why the engine has continuously provided power，Thanks to the intake in the cylinder、Compression、Working、The four strokes of exhaust are operating in an orderly manner。

Inlet itinerary，Pistons move from the tenth point of the cylinder to the lower end point，Open the valve，The exhaust valve is closed，Fresh air and gasoline mixed gas is inhaled into the cylinder。

Compression stroke，Entry、The exhaust valve is closed，Pistons move from the bottom point to the top point，Compress the mixed gas to the top of the cylinder，To increase the temperature of the mixed gas，Prepare for the work itinerary。

Working itinerary，Spark plugs ignite the compressed gas，Hybrid gases occur in the cylinder "explosion" to produce huge pressure，Push the piston from the top point to the bottom stop point，Promote the crankshaft rotation through the connecting rod。

exhaust itinerary，Pistons move from the lower point to the top point，Turn off the valve at this time，Open the exhaust valve，Exile the burning exhaust gas from the cylinder through the exhaust manifold。

Four -stroke diesel engine working principles ....................

The same four -stroke diesel engine Seabetand gasoline engine，Each work cycle is also by the intake itinerary、Compression stroke、Working itineraries and exhaust strokes。Because diesel engines use diesel as a fuel，Compared with gasoline，Diesel's spontaneous combustion temperature is low、Large viscosity、Not easy to evaporate，Therefore, the diesel engine uses compression end to spontaneously ignite。

The principle of working principle of the secondary gasoline engine ..................

There are three holes on the engine gas cylinder，Inlet hole、exhaust holes and air changes，These three holes are closed by the Pistons at a certain time.。

The two rushing journey contained in the work cycle as follows:

The first rush: the piston moves from the lower point to the upward，Three holes are closed at the same time，The mixed gas entering the cylinder is compressed; when the air pores are exposed，Flowing into the crankshaft box。

Second Chuangwan: Pistons compressed to near the upper point，Spark plugs ignite the combustible mixed gas，Gas swelling promotes the piston movement。At this time, the pores are closed，The combustible mixed gas in the crankshaft box is compressed; when the piston is close to the lower end of the lower end, the exhaust hole is turned on，The exhaust gas is rushed out;，Breath in the cylinder，Remove exhaust gas，A ventilation stroke。

The principle of working principle of the rotor engine ..........................

The internal space (or rotor line room) of the shell is always divided into three studios。

During the movement of the rotor，The volume of the three studios constantly changes，Complete air intake in the body tank、Compression、Burning and exhaust four strokes。Each itinerary is performed in different positions in the line -shaped cylinder。
