What are the engine parts, car knowledge
The engine is the heart of the car, providing power for the car's walking, which is related to the car's power, economy and environmental protection. Simply put, the engine is an energy conversion mechanism that converts the thermal energy of gasoline into mechanical energy by propelling the combustion of the gas in the sealed cylinder to push the piston to work.
Since the working principle of the engine is similar, the basic structure is similar. Gasoline engines are usually composed of five major systems: the diesel engine is usually composed of four major systems (no ignition system).
Engine assembly
Crank-link mechanism - the core to achieve thermal energy conversion, but also the basis for the assembly of the engine.
Gas distribution mechanism - to ensure that the cylinder is properly ventilated.
Fuel System - Controls the amount of fuel injected into the cylinder per cycle to regulate the engine's output power and speed. Automotive Engine Cooling System - Controls the normal operating temperature of the engine.
Lubrication system - reduces friction and extends engine life.
Ignition system - timely supply of spark to gasoline engines (diesel engine without ignition system)
Starting system - rotates the crankshaft to complete the engine starting process.
First, the cylinder block crankcase group
1, cylinder block and crankcase
2, oil plate
3, cylinder head
4, cylinder head gasket
Air Supply
Main machine
1. Valve group
The valve group generally consists of a valve, a valve seat, a valve guide, a valve OIL SEAL, a valve spring and a valve lock piece.
2, valve transmission group
(1) Camshaft
(2) Timing gear and TIMING CHAIN or timing pulley
(3) valve tappet
(4) Valve push rod
(5) Rocker arm and rocker arm shaft assembly
What are the engine parts?
Fuel supply system
basic component
The basic composition of the carburetor fuel system, which can be divided into gasoline supply devices (including gasoline tanks, GASOLINE FILTERs, gasoline pumps), air supply devices (including AIR FILTERs, intake muffler, cold and warm air conversion mechanisms, etc.) ), a mixture forming device (carburetor), an intake and exhaust device (including an intake branch pipe, an exhaust branch pipe, and a muffler).
Ignition system
Composition: The traditional type consists of a battery, a generator, an IGNITION COIL, a breaker, a SPARK PLUG, and the like. The conventional and conventional ignition systems are similar, except that the electrical components are used to replace the breakers. The electronic ignition type is all-electronic ignition system, completely eliminating the mechanical device, and the electronic system controls the ignition timing, including battery, generator, ignition coil, spark plug and electronic control system.
cooling system
Composition: Water-cooled type consists of water jacket, water pump, radiator, fan, thermostat and so on. The air-cooled type consists of a fan and a heat sink.
Lubrication system
Composition: It consists of OIL PUMP, filter, pressure limiting valve, oil passage, OIL FILTER and so on.
The above is the engine parts introduced by Xiaobian for everyone, the engine is the heart of the car, so choosing a cost-effective engine is very important for the car.
