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. An internal combustion engine that works on petrol fuel is called petrol engine. It works on the principle of the Otto cycle. In the petrol engine, a carburetor is used to make air petrol mixture that will enter into the cylinder.

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.


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.

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.

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. In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN
