The diesel engine , named after Rudolf Diesel , is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression; thus, the diesel engine is a so-called compression-ignition engine CI engine. This contrasts with engines using spark plug -ignition of the air-fuel mixture, such as a petrol engine gasoline engine or a gas engine using a gaseous fuel like natural gas or liquefied petroleum gas. Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously. With the fuel being injected into the air just before combustion, the dispersion of the fuel is uneven; this is called a heterogeneous air-fuel mixture.
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.
Petrol engine British English or gasoline engine American English is an internal combustion engine with spark-ignition , designed to run on petrol gasoline and similar volatile fuels. In most petrol engines, the fuel and air are usually pre-mixed before compression although some modern petrol engines now use cylinder- direct petrol injection. The process differs from a diesel engine in the method of mixing the fuel and air, and in using spark plugs to initiate the combustion process. In a diesel engine, only air is compressed and therefore heated , and the fuel is injected into very hot air at the end of the compression stroke , and self-ignites. With both air and fuel in a closed cylinder, compressing the mixture too much poses the danger of auto-ignition — or behaving like a compression-ignition engine.
Diesel and Gasoline Engine Lubrication
This paper aims to compare the conditions of in-service oils from diesel and gasoline engines, with focus on nitration. Chemical deterioration was characterized by significant differences in oxidation, nitration, NN increase and residual aminic antioxidant contents. Uncovering differences in the oil degradation of oils from gasoline and diesel engines enables improved condition-based maintenance strategies and the prediction of oil condition dependent tribological performance.

The diesel and petrol engines that are used in most cars are highly similar. In essence, they are internal combustion engines that work using a two or four-stroke cycle. In an internal combustion engine, the power cycle is made up of four phases: intake, compression, power and exhaust. In the intake phase, air is drawn into cylinder through the opening intake valve. In the compression phase, the intake valve closes and air is compressed with fuel. At this point, the mixture of fuel and air is ignited to cause an explosion.
Comparing oil condition in diesel and gasoline engines
You have to decide whether you want a sedan, truck, or SUV. You then have to choose what type of available features you want. You also need to consider whether you want a gas or diesel engine. However, you might then be wondering about the actual difference between gas and diesel. This helpful guide will go over the major differences between these two engines so you can decide which one is right for you.

Light-duty compression-ignition CI engines operating on diesel fuels have the highest thermodynamic cycle efficiency of all light-duty engine types. In a CI diesel engine-equipped vehicle, there is an additional benefit of reduced volumetric fuel consumption e.

It has neither carburettor nor ignition system. The fuel is injected in the form of a very fine spray, by means of a nozzle, into the combustion chamber. There it is ignited by the heat of compressed air which the chamber has been charged with. The diesel engine operates within a fixed sequence of events, which may be achieved either in four or two strokes.
The internal combustion engine was invented around by various scientists and engineers worldwide. Since then the engines have gone through many modifications and improvements. Today, different applications of engines form a significant technological importance in our everyday lives, leading to the evolution of our modern civilization. The invention of diesel and gasoline engines has definitel The invention of diesel and gasoline engines has definitely changed our lifestyles as well as shaped our priorities.

Diesel vs petrol engines
В центре возник нечеткий из-за атмосферных помех кадр, который затем превратился в черно-белую картинку парка. - Трансляция началась, - объявил агент Смит. Это было похоже на старое кино. Кадр казался неестественно вытянутым по вертикали и неустойчивым, как бывает при дрожащем объективе, - это было результатом удаления кадров, процесса, сокращающего видеозапись вдвое и экономящего время. Объектив, скользнув по огромной площади, показал полукруглый вход в севильский парк Аюнтамьенто. На переднем плане возникли деревья.
Он уже ничего не видел и только чувствовал, как тошнотворный комок подкатил к горлу. Его крик эхом отозвался в черноте, застилавшей. Беккер не знал, сколько времени пролежал, пока над ним вновь не возникли лампы дневного света. Кругом стояла тишина, и эту тишину вдруг нарушил чей-то голос. Кто-то звал. Он попытался оторвать голову от пола. Мир кругом казался расплывчатым, каким-то водянистым.
