The miles per gallon equivalent cost of an alternative fuel vehicle can be calculated by a simple formula to directly compare the MPG operating costs (rather than the energy consumption of MPGe [7]) with traditional vehicles since the cost of resources varies substantially from region to region. [5] [4] For reference, the complete equation is:
Estimating the cost savings required to justify the purchase of new equipment. [13] Determining the cost of continuing with existing equipment. [14] Where an asset undergoes a major overhaul, and the cost is not fully reflected in salvage values, to calculate the optimum life (i.e., lowest EAC) of holding on to the asset. [15]
A diesel cycle engine can be as much as 40% to 50% efficient at converting fuel into work, [2] where a typical automotive gasoline engine's efficiency is about 25% to 30%. [3] [4] In general, an engine is designed to run on a single fuel source and substituting one fuel for another may affect the thermal efficiency.
The PL-01 was a Polish light tank concept created by OBRUM with support from BAE Systems, based on the Swedish CV90120-T light tank. [ 1 ] [ 2 ] The concept vehicle was first unveiled at the International Defence Industry Exhibition in Kielce on 2 September 2013, [ 3 ] but the project was scrapped in 2015.
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines- Internal combustion (gasoline, diesel and gas turbine-Brayton cycle engines) and

Volumetric efficiency (VE) in internal combustion engine engineering is defined as the ratio of the equivalent volume of the fresh air drawn into the cylinder during the intake stroke (if the gases were at the reference condition for density) to the volume of the cylinder itself.
