Are tanks diesel-electric?

Traditional armored vehicles, including tanks, use engines running on diesel or gasoline. The need to drive a 60-ton vehicle cross-country, as well as provide power to fire control, sensors, and environmental systems, requires powerful engines.

Are electric engines more powerful than diesel?

Once the energy is on board (not counting the efficiency of the power generation, oil refining, or charging), the Tesla is using only about a third as much energy as the comparable gasoline-powered car.” Based on the average figures supplied for diesel engines, EVs are still more efficient, by about a third.

Why do diesel locomotives use electric motors to drive wheels?

In the 1930s, the system was adapted for streamliners, the fastest trains of their day. Diesel–electric powerplants became popular because they greatly simplified the way motive power was transmitted to the wheels and because they were both more efficient and had greatly reduced maintenance requirements.

What are the advantages of diesel-electric?

They include a more efficient propulsion system, less pollution, increased operational efficiency, especially at slow speeds (important for applications such as dynamic positioning), and flexibility in locating machinery compartments.

What voltage do diesel-electric locomotives work?

Modern locomotives incorporate traction inverters, AC to DC, capable of delivering 1,200 volts (earlier traction generators, DC to DC, were capable of delivering only 600 volts).

What are the disadvantages of diesel-electric traction?

As compared with an electric locomotive, however, the diesel-electric has an important drawback: since its output is essentially limited to that of its diesel engine, it can develop less horsepower per locomotive unit.

Is diesel-electric efficient?

The diesel-electric system offers flexibility of fuel and as will be shown, could be driven coast-to-coast, nonstop, with an efficiency of around 75 miles per gallon.
