Why Diesel Engines Benefit the Most from Turbochargers in Terms of Fuel Efficiency and Emission Reduction

Assalamualaikum and welcome to my blogger again, for this week I want to share some information about turbocharger are benefit to reduce emission and fuel efficiency for diesel engine.

First, what is a turbocharger ? A turbocharger is a forced induction device that is powered by the flow of exhaust gases is a turbocharger, also known as a turbo. In order to generate more power for a given displacement, it uses this energy to compress the intake gas and force more air into the engine.

Why Turbochargers are Particularly Effective at Increasing Fuel Efficiency and Reducing Emissions for Diesel Engines

Fuels with a high energy density, like diesel, have a high carbon to hydrogen content. Natural gas (methane), for example, is a low-energy dense fuel that contains fossil fuel hydrocarbons with a carbon to hydrogen atom ratio of 1:4 or 1:5. Diesel and other high energy density fuels have ratios that are more like 1 to 2. High energy density fuels with high carbon to hydrogen ratios are very stable, while being advantageous in many ways.

Fuel stability is a term used to characterise a fuel's difficulty in burning. Natural gas and propane are examples of low energy, highly homogenised fuels that are very volatile and so easily ignite. Low-density fuels can be burned with just one match. High energy fuels, however, are far more challenging to ignite. It is essentially difficult to ignite coal with a single match. Only marginally more likely are the chances of lighting a single match to ignite a gallon of diesel.

Although fuel stability is a great quality for safety and pre-combustion emissions — fuels with high energy densities evaporate at much lower and slower rates than fuels with low energy densities — it is also the reason that fossil fuels with high energy densities burn inefficiently and produce a lot of different kinds of emissions.

That is to say, fossil fuels with a high energy content are not necessarily dirtier than other fossil fuels; rather, we simply lack engines, furnaces, or boilers that can complete a burn.

A turbocharger enters the picture at this point. Diesel is incredibly stable and packed with energy, and a turbo boosts the efficiency of combustion. A turbocharger enhances the energy that diesel generates by improving the combustion efficiency of an engine, and also decreases emissions by turning a greater proportion of diesel fuel into carbon dioxide or water rather than a hazardous exhaust.
