What is diesel-electric traction?

What is diesel-electric traction?

The defining characteristic of diesel–electric transmission is that it avoids the need for a gearbox, by converting the mechanical force of the diesel engine into electrical energy (through a dynamo), and using the electrical energy to drive traction motors, which propel the vehicle mechanically.

Are there any diesel hybrids?

But only one of them pairs the diesel engine and electric motor together into a single powertrain: the Mercedes-Benz E 300 BlueTEC Hybrid. The other two–the Peugeot 3008 HYbrid4 and the Citroën DS5 Hybrid–are what is known as “through-the-road hybrids,” meaning that they have one powertrain on either end.

Why is diesel-electric efficient?

“With diesel-electric, the diesel engines and generators can be put higher up, giving the operating benefits of less ducting for air intakes and exhausts that also takes up less space within the vessels. It also allows a better distribution of the equipment,” said Murray.

Which is better diesel or electric locomotive?

Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. Electric locomotives usually cost 20% less than diesel locomotives, their maintenance costs are 25-35% lower, and cost up to 50% less to run.

Why isn’t there a diesel hybrid?

The Added Cost Of DEF Systems Are Too Expensive An excellent running diesel with a DEF system will produce far fewer tailpipe emissions than a gasoline car. The downside is that when trying to combine a diesel DEF system into a hybrid, you are adding weight and cost, both of which are not why hybrids were developed.

Is diesel hybrid good?

Diesel-electric hybrids are designed to offer diesel-levels of economy, with the ability for electric-only running in urban areas, thereby reducing emissions from the diesel engine. Hybrids can provide the performance of a larger engine with the economy of a smaller one.

Can you replace electric with diesel?

Electric trucks may soon challenge diesel if charging hurdle cleared, study shows. Battery-powered trucks have often been dismissed as too costly to replace diesel trucks in many capacities, with batteries too heavy for long-haul freight. But researchers at SEI said a tipping point was now in sight.

What is the cost of a diesel locomotive?

A diesel locomotive could cost from $500,000-$2 million. While an electric locomotive could cost more than $6 million. Price depends on whether it is powered by AC or DC traction, how much horsepower it has, or what electronics it is equipped with.

What is a diesel electric transmission?

A diesel–electric transmission, or diesel–electric powertrain is a transmission system for vehicles powered by diesel engines in road, rail, and marine transport. Diesel–electric transmission is based on petrol–electric transmission, a very similar transmission system used for petrol engines .

What are diesel electric drives used for?

Diesel electric drives found a natural application in submarines and many surface ships. Today’s cruise ships, where 70-80 percent of the total onboard power is required for the “hotel” side of the vessel, are diesel electric powered. The power demands can be enormous at times.

How does a diesel electric power system work?

A diesel electric power system can drive multiple propellers from a single engine or use multiple engines to power one or more props. In a twin-engine/twin-prop system, one engine can power both props when operating within the speed limits imposed in many areas.

What is a diesel electric drive on a cruise ship?

Diesel electric drives found a natural application in submarines and many surface ships. Today’s cruise ships, where 70-80 percent of the total onboard power is required for the “hotel” side of the vessel, are diesel electric powered. The power demands can be enormous at times.
