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 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. The petrol-fuelled spark-ignition engine is characterised by the use of a spark plug to initiate the combustion process. The engine uses a piston which is driven up and down inside a cylinder and connected to the drive section by a rotating crankshaft.

Difference Between Petrol and Diesel Engine [With PDF]

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.

This chapter provides an overview of the various elements that determine fuel consumption in a light-duty vehicle LDV. The primary concern here is with power trains that convert hydrocarbon fuel into mechanical energy using an internal combustion engine and which propel a vehicle though a drive train that may be a combination of a mechanical transmission and electrical machines hybrid propulsion. A brief overview is given here of spark-ignition SI and compression-ignition CI engines as well as hybrids that combine electric drive with an internal combustion engine; these topics are discussed in detail in Chapters 4 through 6.

Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil , but alternatives that are not derived from petroleum, such as biodiesel , biomass to liquid BTL or gas to liquid GTL diesel, are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is increasingly called petrodiesel in some academic circles.

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. The Diesel engine is used for heavier vehicles.

The classification of the petrol and diesel engine is done on the basis of the respective fuel used by these engines.
