DIESEL INDEX = ((ANILINE POINT(DEG F))(API GRAVITY))/100 A higher aniline point (and therefore a lower aromatic content) in diesel oil is desirable, in order to prevent autoignition in diesel

The burning of diesel fuel creates exhaust gases, and while there can be slight differences from engine to engine, those gases are created in known quantities. By knowing the rate at which a generator or other engine consumes fuel, a very accurate calculation of carbon dioxide (CO2) emissions can be obtained.

The compression ratio of an engine is a very important element in engine performance. The calculation for power includes a term for efficiency η. This efficiency is the product of three efficiencies within the engine. Find out more about these efficiencies and comment on their existence. WHERE TO FIND MORE 1. Basic Engineering Mathematics, John Bird, 2007, published by Elsevier Ltd. 2.

The calculated value is termed the "cetane index by four-variable equation". Throughout the remaining text of this document, the term "cetane index" implies cetane index by four-variable equation. Diesel engine operation is primarily related to the actual cetane number and the cetane index is simply an estimation of the base (unadditized) cetane number. Diesel consist for 86,2% of carbon, or 720 grammes of carbon per liter diesel. In order to combust this carbon to CO 2, 1920 grammes of oxygen is needed. The sum is then 720 + 1920 = 2640 grammes of CO 2 /liter diesel.

The increase in both Diesel Index and Cetane Number indicates good quality fuel. The Commercial Fleet diesel cost calculator is designed to help fleets estimate diesel costs for either the entire fleet or an individual van. Select the fuel type, mileage covered and the vehicle make, model and derivative to get an estimated cost of fuel.

Feb 26, 2020 Hydrocarbon-based fuels which are gasoline, diesel, natural gas, and which measure the fuel propensity to ignite, are called cetane index,

Here is a link to the calculator: Fuel savings calculator (Excel file). How to pay for fuel if cash is tight. Paying for fuel can be a challenge for new and growing owner-operators. It is one of your highest (if not the highest) variable expenses, and you have to pay for it up front.. If you need funds for fuel, or if cash is tight due to slow broker/shipper payments, consider freight factoring.
