An internal combustion engine is the engine in which combustion burning of fuel takes place inside the cylinder of engine. By burning of the fuel high temperature and pressure force generates. This pressure force use to move the vehicle or rotate wheels by use of some mechanism. In an engine many parts work together and achieve the goal of converting chemical energy of fuel into mechanical energy.

List of Car Engine Parts: Its Function (With Pictures)

An internal combustion engine is the engine in which combustion burning of fuel takes place inside the cylinder of engine. By burning of the fuel high temperature and pressure force generates. This pressure force use to move the vehicle or rotate wheels by use of some mechanism. In an engine many parts work together and achieve the goal of converting chemical energy of fuel into mechanical energy.

These parts are bolted together and the combination of all these parts is known as engine. Today I am going to tell you about these parts and how they work so you can know the basic of automobile engine. It is a container fitted with piston, where the fuel is burnt and power is produced. Cylinder is the main body of IC engine. Cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. The main function of cylinder is to guide the piston.

For cooling of cylinder a water jacket for liquid cooling used in most of cars or fin for air cooling used in most of bikes are situated at the outer side of cylinder. At the upper end of cylinder, cylinder head and at the bottom end crank case is bolted. One end of the cylinder is closed by means of cylinder head. This consists of inlet valve for admitting air fuel mixture and exhaust valve for removing the products of combustion.

The inlet valve, exhaust valve, spark plug, injector etc. The main function of cylinder head is to seal the cylinder block and not to permit entry and exit of gases on cover head valve engine. Material: Aluminium alloys Manufacturing Method: Casting. Piston is used to reciprocate inside the cylinder. It transmits the energy to crankshaft through connecting rod.

Manufactuirng Method: Casting. These are used to maintain a pressure tight seal between the piston and cylinder walls and also it transfer the heat from the piston head to cylinder walls. These rings are fitted in grooves which have been cut in the piston. They are split at one end so they can expand or slipped over the end of piston. One end of the connecting rod is connected to piston through piston pin while the other is connected to crank through crank pin.

It transmits the reciprocatory motion of piston to rotary crank. There are two end of connecting rod one is known as big end and other as small end.

Big end is connected to the crankshaft and the small end is connected to the piston by use of piston pin. Connecting Rod 6. Crank:- It is a lever between connecting rod and crank shaft. Crank Shaft:- The function of crank shaft is to transform reciprocating motion in to a rotary motion. The crankshaft of an internal combustion engine receives the efforts or thrust supplied by piston to the connecting rod and converts the reciprocating motion of piston into rotary motion of crankshaft.

The crankshaft mounts in bearing so it can rotate freely. The shape and size of crankshaft depends on the number and arrangement of cylinders. Material: 37C15 Alloy Steel. Manufacturing Method: Casting. Fly wheel is a rotating mass used as an energy storing device. A flywheel is secured on the crankshaft. The main function of flywheel is to rotate the shaft during preparatory stroke. It also makes crankshaft rotation more uniform.

Material : castManufacturing Method : Casting. Flywheel 9. Crank Case:- It supports and covers the cylinder and the crank shaft. It is used to store the lubricating oil. The main body of the engine to which the cylinder are attached and which contains the crankshaft and crankshaft bearing is called crankcase. It serves as the lubricating system too and sometime it is called oil sump. All the oil for lubrication is placed in it.

Materials: Phosphorus Bronze and Monel metal. The main function of a sparkplug is to conduct the high potential from the ignition system into the combustion chamber. It provides the proper gap across which spark is produced by applying high voltage , to ignite the mixture in the ignition chamber. Manufacturing Method: Each major element of the spark plug—the center electrode, the side electrode, the insulator, and the shell—is manufactured in a continuous in-line assembly process.

Then, the side electrode is attached to the shell and the center electrode is fitted inside the insulator. Finally, the major parts are assembled into a single unit. Spark Plug Engine Bearing: The crankshaft is supported by bearing. Everywhere there is rotary action in the engine , bearings are used to support the moving parts.

Its purpose is reduce the friction and allow parts to move freely. A device for regulating automatically output of a machine by regulating the supply of working fluid. When the speed decreases due to increase in load the supply valve is opened by mechanism operated by governor and the engine therefore speeds up again to its original speed.

Thus the function of a governor is to control the fluctuations of engine speed due to changes of load. The function of a carburetor is to atomize and meter the liquid fuel and mix it with the air as it enters the induction system of the engine. Maintaining fuel-air proportion under all conditions of operation appropriate to the conditions. Fuel Atomizer or Injector Fuel injection is a system for mixing fuel with air in an internal combustion engine.

It has become the primary fuel delivery system used in automotive petrol engines, having almost completely replaced carburettors in the late s. The primary difference between carburettors and fuel injection is that fuel injection atomizes the fuel by forcibly pumping it through a small nozzle under high pressure, while a carburettor relies on low pressure created by intake air rushing through it to add the fuel to the airstream.

The fuel injector is only a nozzle and a valve: the power to inject the fuel comes from a pump or a pressure container farther back in the fuel supply. Manifold The main function of manifold is to supply the air fuel mixture and collects the exhaust gases equally form all cylinder.

In an internal combustion engine two manifold are used, one for intake and other for exhaust. Material : Aluminium alloy -Alloy Manifold Gudgeon pin or piston pin These are hardened steel parallel spindles fitted through the piston bosses and the small end bushes or eyes to allow the connecting rods to swivel. It connects the piston to connecting rod. It is made hollow for lightness.

Material: Plain Carbon steel 10C4. Pushrod Pushrod is used when the camshaft is situated at the bottom end of cylinder. It carries the camshaft motion to the valves which are situated at the cylinder head. Like Like. Like Liked by 1 person. You are commenting using your WordPress.

Gasoline engine

In this post, we will discuss the engine parts. The engine has two types one is the internal combustion engine and another one is the external combustion engine. The engine most essential part of automobile industries or we can say that the engine is the heart of an automobile. The function and construction of each engine parts of an internal combustion engine are explained. The key to the engine is as follows. Fig shows a simple sketch of the cylinder block. Cylinder block, cylinder head and crankcase these three parts form the foundation and main stationary body of the automobile engine.

In this type of engine, the combustion of the fuel occurred inside the engine. And produced thrust which applies to some components of the Engine. Also, this thrust or force produces a vertical or horizontal movement on the components. An Internal Combustion Engine consists of several important parts, and those are:. These are the major parts which an Internal Combustion Engine has.

Diesel engine

Diesel combustion

An engine or motor is a machine designed to convert one form of energy into mechanical energy. The internal combustion engine is perhaps the most common example of a heat engine, in which heat from the combustion of a fuel causes rapid pressurisation of the gaseous combustion products in the combustion chamber, causing them to expand and drive a piston , which turns a crankshaft. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air , and clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors , like myosins in muscles , use chemical energy to create forces and ultimately motion. The word engine derives from Old French engin , from the Latin ingenium —the root of the word ingenious. Pre-industrial weapons of war, such as catapults , trebuchets and battering rams , were called siege engines , and knowledge of how to construct them was often treated as a military secret.

Diesel engine , any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder , where combustion and expansion actuate a piston. It converts the chemical energy stored in the fuel into mechanical energy , which can be used to power freight trucks, large tractors, locomotives, and marine vessels. A limited number of automobiles also are diesel-powered, as are some electric-power generator sets. The diesel engine is an intermittent-combustion piston-cylinder device. It operates on either a two-stroke or four-stroke cycle see figure ; however, unlike the spark-ignition gasoline engine , the diesel engine induces only air into the combustion chamber on its intake stroke.
