A Marine diesel engine consists of many working parts. Even different components make few modification in its design but their function remains the same. Each component has a definite function and location in its working.

From Fuel to Function: Working of the Car Engine Explained

Introduction In general, engines convert heat energy into mechanical energy by exploiting gas onto the piston and crankshaft assembly. The amount of energy depends on the rotational speed of crank shafts as per specifications.

An internal combustion engine ICE is more efficient than a steam engine because an ICE is simple to start and disengage. An ICE is widely used in the field of transportation. Generally, it is made of sheet metal. Most fuel tanks have a fuel gauge to check the fuel level and a drain plug to drain fuel. The pressure required to inject fuel into the combustion chamber to offset the pressure of compression is typically to psi.

This work is mainly done by the injection pump. The injector nozzle atomizes fuel, which is the breaking up of fuel into small particles. The fuel must be atomized when it enters the combustion chamber.

Atomization occurs at a pressure between 1, to 4, psi. The oil is stored in the oil sump, from where an oil pump takes the oil through a strainer and delivers it through a filter to the main gallery. From the main gallery, the oil flows to the main bearings. After lubricating the main bearings, some of the oil falls back to the sump, some is splashed to the cylinder walls, and the remaining oil goes through a hole to the crankpin. From the crankpin, the oil travels to the piston pin through a hole in the connecting rod web where it lubricates the piston rings.

For lubricating camshaft and timing gears, the oil is led through the separate oil line from the oil gallery. The valve tappets are lubricated by connecting the main oil gallery to the tappet guide surfaces through drilled holes. Our FE mechanical exam review course thoroughly explains the fundamental concepts and functional applications of mechanical engineering equipment parts. Oil Cooler An oil cooler is used for cooling lubricating oil. Higher temperatures will reduce the viscosity of oil, which causes a harmful oil film to form between moving parts.

To eliminate this, an engine oil cooler is used. Filters generally have pores on the surface, which are measured by microns.

The lowest micron value typically has better filtration. A filter set contains outer and safety filters in heavy diesel engines for better filtration. Turbo chargers have two impellers fixed on the same shaft. These impellers are driven by exhaust air. Generally, the air sucked in by the air filter is compressed before entering the cylinder bore, which results in high efficiency.

The shaft will rotate at the speed of approximately , rpm to result in a longer engine life. The opening and closing of the valve is controlled by a camshaft. The exhaust gases have a higher pressure than atmosphere; if these gases were to be released directly to the atmosphere, a loud, unpleasant noise would sound, similar to the sound of firing a gun.

The muffler is used to cool the exhaust gases. The water in the jackets absorb heat from the cylinders. The heated water conducted through the radiator helps cool the water. A starter motor receives its power supply from the battery.

The pinion of the starter motor engages with the teeth of a flywheel ring and rotates, which then rotates the crankshaft.

This rotation of crankshaft leads to the movement of pistons in the cylinders. The piston will suck air and fuel into the combustion chamber, which causes the engine to start. After reaching a specific rpm, the starter motor withdraws its pinion from the flywheel. The belt is used to drive the shaft of the alternator. The main job of the alternator is to charge the batteries. This website uses cookies to ensure the best experience possible.

In general, engines convert heat energy into mechanical energy by exploiting gas onto the piston and crankshaft assembly. Important components of internal combustion engines include:. In an engine, fuel reaches the cylinder bore through the following path:.

In this system, the engine parts are lubricated under pressure feed. An oil cooler is used for cooling lubricating oil. Every cylinder in an engine is surrounded by water jackets. Mechanical engineers preparing for the FE exam are strongly encouraged to review heating and cooling systems prior to taking the FE Mechanical exam. The electrical system of an engine is comprised of the following parts:.

Marine Diesel Engine – Parts And Functions

Have you ever wondered how fascinating a car is? It is a device where you pour in some liquid, sit on a chair and use simple movements from your hand and feet to get to places faster. But it has happened and going at the current rate things are only going to get better. We will take a look at its intricate components and their individual functions. In broad terms, the engine can be segregated into three key parts, the head, the block and the oil sump.

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.

Just like humans in order to move, your engine requires energy. In fact, the core responsibility of the engine is to transform energy from fuel with a spark, to create the power to move. This internal combustion creates tiny, contained explosions to produce movement. Car engines are designed around sealed, resilient metal cylinders. Most modern vehicles have between four and eight cylinders , though some vehicles can have as many as sixteen!

Звонок из Соединенных Штатов. Он улыбнулся. Значит, все правда.

 Ну что, вы решили. Я ее убиваю. Стратмор мгновенно взвесил все варианты. Если он позволит Хейлу вывести Сьюзан из шифровалки и уехать, у него не будет никаких гарантий.

Лиланд Фонтейн окинул своего помощника убийственным взглядом. - Я был. Но сейчас я .

Это произвело на дешифровщиков впечатление, но тем не менее Беккер продолжал переводить знаки вразнобой, а не в той последовательности, в какой они были расположены в тексте. - Это для вашей же безопасности, - объяснил Морант.  - Вам незачем знать, что вы переводите. Беккер засмеялся.
