An Audi R10 TDI LMP race car, fueled on Shell V-Power Diesel. V-Power Diesel is Shell's version of an enhanced diesel fuel, similar to BP's 'Ultimate Diesel'. Like BP Ultimate Diesel, Shell V-Power Diesel is designed for modern compression-ignition diesel engines, to facilitate enhanced engine performance along with increased engine protection, for more consistent operation and engine longevity.
Engines using the Diesel cycle are usually more efficient, although the Diesel cycle itself is less efficient at equal compression ratios. Since diesel engines use much higher compression ratios (the heat of compression is used to ignite the slow-burning diesel fuel), that higher ratio more than compensates for air pumping losses within the engine.
However, practical Diesel engines are 30% - 35% more efficient than gasoline engines. [7] This is because, since the fuel is not introduced to the combustion chamber until it is required for ignition, the compression ratio is not limited by the need to avoid knocking, so higher ratios are used than in spark ignition engines.
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
Diesel engines are used in aircraft, automobiles, power generation, diesel–electric locomotives, and both surface ships and submarines. The Diesel cycle is assumed to have constant pressure during the initial part of the combustion phase (to in the diagram, below). This is an idealized mathematical model: real physical diesels do have an ...
Sanchez, who previously worked on gas-powered cars and now focuses on EVs, said it can cost less to repair a water damaged EV than a car with a combustion engine - if you are lucky.
In addition diesel fuel has slightly higher energy density by volume than gasoline. This makes Diesel engines capable of achieving much better fuel economy than gasoline vehicles. Biodiesel (fatty acid methyl ester), is commercially available in most oilseed-producing states in the United States. As of 2005, it is somewhat more expensive than ...
Isuzu 10TD1 diesel engine. A V10 engine is a ten-cylinder piston engine where two banks of five cylinders are arranged in a V configuration around a common crankshaft.V10 engines are much less common than V8 and V12 engines.
