What are the basic parts of an engine?
Basic Engine Parts
- Spark plug. The spark plug supplies the spark that ignites the air/fuel mixture so that combustion can occur. …
- Valves. The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. …

What are the valves in an engine?
Engine valves are mechanical components used in internal combustion engines to allow or restrict the flow of fluid or gas to and from the combustion chambers or cylinders during engine operation.
What are the parts of a valve train?
The valve train typically includes the camshaft, valves, valve springs, retainers, rocker arms and shafts. On engines with traditional mounting of the camshaft in the cylinder block, the valve train also includes lifters and pushrods.
How many types of engine valves are there?
There are mainly two different types of valves used in internal combustion engines, differentiated as Intake Valve and Exhaust Valve. The valves called Intake engine valves let fuel and air mixture get into the cylinder and the Exhaust Valve lets the evacuate out of the cylinder.
What are the 3 main engine systems?
- Mechanical fuel injection systems.
- Operating systems.
- Piston rings.
- Primary system.
- Spark ignition systems.
- Spring retainers.
How many parts are in a engine?
In broad terms, the engine can be segregated into three key parts, the head, the block and the oil sump. 1. The cylinder head is the channel through which the fuel enters the engine chamber and exhaust gases exit. Its key components are the camshafts, valves and spark plug.
Does more valves mean more power?
More valves equal better airflow and a more efficient engine. Smaller valves are lighter, which means the engine can rev higher, create more power, and in general, look down upon the two-valve engines of the world with a sense of multi-valve satisfaction.
Why is 4 valves better than 2?
4 valves per cylinder allows for more airflow than 2 valves per cylinder, as there is larger open area when the valves are open. Having a configuration with DOHC and four valves per cylinder means better airflow, especially at high engine speeds, resulting in better top end power.
What size engine is a 16 valve?
16 valves (16v) means 4 valves/cyl (two each for intake and exhaust). The 16v engine is better in terms of performance as it has an easier time taking in air and pushing out exhaust (i.e, breathing).
What turns faster crank or Cam?
Because one turn of the camshaft completes the valve operation for an entire cycle of the engine and the four-stroke-cycle engine makes two crankshaft revolutions to complete one cycle, the camshaft turns half as fast as the crankshaft. …
What controls the opening of engine’s valves?
As the crankshaft rotates, each valve is opened by means of a tappet, pushrod and rocker arm. The valve is closed by spring pressure. The camshaft drive-chain sprocket has twice as many teeth as the crankshaft sprocket, so that the camshaft rotates at half engine speed.
How does a valve train work?
The bottom end of a pushrod is fitted with a lifter, upon which the camshaft makes contact. The camshaft lobe moves the lifter upwards, which moves the pushrod. The top end of the lifter pushes on the rocker arm, which opens the valve.
What is a 3 valve engine?
Unlike a two-valve engine, where there is only one intake valve, a three or four-valve setup allows manufacturers to design the engine in such a way that each intake valve opens at a slightly different time. The technique is also known as variable valve timing.
What are types of valves?
Different types of valves are available: gate, globe, plug, ball, butterfly, check, diaphragm, pinch, pressure relief, control valves etc. Each of these types has a number of models, each with different features and functional capabilities.
What material is a valve made of?
|Base material||Valve body||Stem|
|Bronze / Brass||Bronze (CAC401) Brass (C3771)||K metal (C3531) Stainless steel|
|Cast iron||Gray cast iron (FC200)||Stainless steel|
|Ductile iron||Ductile iron castings (FCD-S)||Stainless steel|
|Cast steel||Carbon steel castings for high temperature / pressure service (SCPH 2)||Stainless steel|
