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.

How Diesel Engines Work

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.

This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to a crankshaft, and the up-and-down motion of the pistons, known as linear motion, creates the rotary motion needed to turn the wheels of a car forward. Both diesel engines and gasoline engines convert fuel into energy through a series of small explosions or combustions. The major difference between diesel and gasoline is the way these explosions happen. In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. In a diesel engine, however, the air is compressed first, and then the fuel is injected.

Petrol engine

I am Amrit, and today I am going to discuss what are the differences between the petrol engine vs Diesel Engine. And how you can defer this in technical terms. So let me first tell you a little about Petrol and Diesel Engine. As the name suggests "Petrol", you make a simple definition of a Petrol engine like an engine where we use petrol as fuel to produce power is called a petrol engine. The full form of SI is Spark Ignition.

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.

Diesel engine

The classification of the petrol and diesel engine is done on the basis of the respective fuel used by these engines. The engine which uses petrol is called petrol engine while that uses diesel is called diesel engine. Here will discuss all the major differences among these engines.

Таких посланий она получила больше двух десятков. И все был подписаны одинаково: Любовь без воска. Она просила его открыть скрытый смысл этих слов, но Дэвид отказывался и только улыбался: Из нас двоих ты криптограф.
