So why does the M-1 tank use a 1,500 horsepower gas turbine engine instead of a diesel engine? It turns out that there are two big advantages of the turbine over the diesel: Gas turbine engines have a great power-to-weight ratio compared to reciprocating engines. That is, the amou...
Rocket engines are up to 60% efficient. Efficiency is a measure of how much of the chemical energy in a fuel source is converted to kinetic energy... Learn more about this topic: Heat Engine Definition, Efficiency & Formula from Chapter...
Stephenson's work in developing increasingly efficient steam engines for transporting coal led to the decision to create a rail link between Durham Coalfields and a shipping port in Stockton. Stephenson suggested that the plan also permit the engines to carry passengers. In 1825, Stephenson ...
However, large eddy simulations (LES) are used to resolve the core turbulent flow. The blending of the RANS and LES models allows for better near-wall heat transfer modeling and alleviates the need for a fine mesh near the wall. This makes flameout simulation more efficient. A map showing ...
Turbocharged engines generate more power than naturally-aspirated engines of the same size. And the combustion process becomes more efficient. Furthermore, this helps reduce emissions and enhance the driving experience. A turbocharger is highly engineered with high-value components. The next step ...

Even though fuel-efficient cars are currently going in a different direction (hybrids, electrics and biofuels), it's not incomprehensible to say that someday, someone could find a way to scale down a super-efficient gas-turbine engine and stuff it under the hood of a car. Related Articles ...
So it is possible to make working jet engines, as experimental devices with very limited materials and simple designs. The point is not to necessarily to make an efficient engine in terms of performance, RPM, power etc. But to make an engine that is efficient in terms of experience, ...
High-performance and modern fuel-efficient engines are either turbocharged or supercharged, which means that air coming into the engine is first pressurized (so that more air/fuel mixture can be squeezed into each cylinder) to increase performance. The amount of pressurization is called boost. A ...
Unfortunately, due to a number of factors like heat, friction, exhaust restriction, and a little property called inertia, a turbo isn’t 100% efficient. So, a more realistic expectation would be a 30- to a 40-percent increase in power depending on your particular set-up. Let’s take a...
