Hundreds of engine parts work together to form the precise construction of an engine. This article will give you a detailed introduction:
1. Crank connecting rod mechanism: like connecting rod, crankshaft, axle shaft, flywheel, piston, piston ring, piston pin, crankshaft oil seal, etc., which is the core of thermal energy conversion, and it can turn the linear reciprocating motion of piston into the rotary motion of the crankshaft to output power to the outside world.
2. Gas distribution mechanism: cylinder head, valve cover, camshaft, valves, intake manifold, exhaust manifold, air filter, silencer, three-way catalytic, supercharger, intercooler, etc., is responsible for the timely exchange of air to the cylinder.
3. Cooling system: generally consists of a water tank, water pump, radiator, fan, thermostat, water temperature gauge and drain switch. The automobile engine is mainly cooled by water, which can regulate the normal working temperature of the engine. 4.
4. Lubrication system: it consists of oil pump, collector filter, oil filter, oil channel, pressure limiting valve, oil gauge, pressure sensing plug and dipstick, etc. It can reduce the friction and prolong the life of the engine.
5. Fuel system: gasoline engine fuel system consists of gasoline tank, gasoline gauge, gasoline pipe, gasoline filter, gasoline pump, carburetor, air filter, intake and exhaust manifolds. Nowadays, most of the gasoline is directly injected into the cylinder and inhaled into the cylinder air mixture, and then ignited with an electric spark to produce power.
6. Starting system: starter, ignition switch, battery, which enables the engine to start and run.
7. Ignition system: spark plugs, high voltage wires, high voltage coils, distributor, responsible for timely ignition.
8. Cylinder block crankcase group: including cylinder block, crankcase, engine oil sump, cylinder head, cylinder gasket sealing plate, etc.
9. Intake drive unit: for example, valve group, mostly composed of valves, valve seats, valve guides, valve seals, valve springs and valve locks. There are also valve drive groups, like camshafts, timing gears and timing chains or timing pulleys, valve tappets, valve pushrods, rocker arms and rocker arm shaft assemblies.
10. Combustion system: The traditional one consists of battery, generator, ignition coil, circuit breaker, spark plugs, etc. Nowadays, common electronic ignition system replaces the circuit breaker with electronic components, which can control the ignition time more accurately.
There are numerous engine parts, each of which plays an important role in the normal operation of an engine. From the mechanical dance of the crank connecting rod to the chemical symphony of the combustion chamber, from the art of heat balance in the cooling system to the philosophy of drag reduction in the lubrication system, these precision components are integrated through systematization to jointly advance the progress of human civilization. With the integration of material science, electronic control and artificial intelligence technologies, engine accessory systems are evolving towards greater efficiency, intelligence and environmental protection.
