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.

Diesel engine

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 low-speed i. A four-stroke diesel engine resembles a gasoline engine as it works on the four-stroke cycle, that is: admission, compression, power and exhaust.

A four-stroke also four-cycle engine is an internal combustion IC engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed:. Nicolaus August Otto was a traveling salesman for a grocery concern. In his travels, he encountered the internal combustion engine built in Paris by Belgian expatriate Jean Joseph Etienne Lenoir. The Lenoir engine ran on illuminating gas made from coal, which had been developed in Paris by Philip Lebon. In testing a replica of the Lenoir engine in , Otto became aware of the effects of compression on the fuel charge.

Automotive engines have transformed over the years, but two main gasoline powered combustion engine designs remain: the 2-stroke and the 4-stroke. How do they work, and which is better? Read on to learn the answers! In order to understand how these two engines are different, you first need to become familiar with the basics. The Difference between a 2-stroke and a 4-stroke engine is how quickly this combustion cycle process occurs, based on the number of times the piston moves up and down during each cycle. In a 4-stroke engine, the piston completes 2-strokes during each revolution: one compression stroke and one exhaust stroke, each being followed by a return stroke. The spark plugs fire only once every other revolution, and power is produced every 4-strokes of the piston.

The vast majority of the world's road vehicles are powered by petrol and diesel internal combustion engines ICEs , so I will start by looking at this technology, the emissions involved and ways that these emissions could be reduced.

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. Diesel engines are typically constructed with compression ratios in the range to Both two-stroke and four-stroke engine designs can be found among engines with bores cylinder diameters less than mm 24 inches.


The primary difference between Petrol and Diesel engines is that the Petrol engine works on the Otto cycle whereas the Diesel engine works on the Diesel cycle.


Four-stroke engine

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.

The main difference between petrol 4 stroke vs diesel 4 stroke is the way fuel is introduced into the combustion chamber. In diesels, usually the fuel is injected at​.

    Both Air and fuel mixture is drawn into the cylinder in the petrol engine. Only air is drawn into the cylinder in the diesel engine. In Petrol Engine Spark Plug is fitted with the cylinder. In the Diesel engine, the Fuel Injector is fitted with the cylinder.
