Why are submarines hybrids?

All submarines have at least 2 methods of propulsion; with nuclear power, steam generated moves the turbines/main engines, and also makes electricity for battery storage in case of main propulsion failure (electric motor propulsion). A backup Diesel-Generator is also aboard for making electricity if the reactor is down. Diesel-Electric boats run on electric motors (battery powered) submerged, and on their diesel engines while surfaced.


What kind of diesel engines are on refrigeration trailers?

The main two refrigeration giants are Thermo King and Carrier


Diesel fuel is used in the engines of the machines and trucks at the quarry Which of these is the main energy transformation as the fuel is used by the engines?

Chemical energy is converted to kinetic energy.


What is the advantage of Diesel engines?

One of the main advantage of using a Diesel engine as opposed to a regular is that a Diesel engine tends to burn less fuel. They also have very high thermal efficiency.


Are alfa jtd motor is good?

The JTD engine is good, and one of the most advanced diesel engines when it was released. It is also sold by General Motors as their main diesel engine.


The main difference between the internal combustion engine and the diesel engine is?

The diesel engine doesn't have any spark plugs, and uses heat generated during compression to ignite the fuel. The diesel however, is an internal combustion engine.


What main pollutants are present in small amounts?

Temporary pollunt&bio-degradable pollutants.


Whats the difference between engines running on diesel and gasoline?

Gas engines use spark plugs to ignite the air fuel mixture and diesel engines use high cylinder compression to ignite the fuel air mixture. Other than that they are similar. <><><> Diesel engines ignite the fuel by using high compression: as the engine compresses the air inside the combustion chamber, it reaches around 1000 degrees, at which point diesel fuel is injected into the combustion chamber, and it ignites. Gasoline engines use the sparks from spark plugs to ignite the gasoline/air mixture in the engines' combustion chambers after it has been compressed. Because separate sparks are used the amount of compression required in a gasoline engine is a lot less than would be necessary in a diesel engine. The main reason diesel engines are heavier and more expensive to make than gasoline engines is because, to be able to withstand the much higher compression, diesel engines have to be made much stronger by having thicker cylinder walls, compression chambers, pistons, connecting rods, crankshafts, etc.


What is the difference in bhp between petrol and diesel engines?

Both our internal combustion engines but the main difference is that a petrol engine uses spark plugs to ignite the fuel but a diesel engine has no spark plugs but instead uses compression to ignite the fuel. A diesel engine is also built much stronger than a gasoline/petrol engine. Diesel engines get better fuel mileage, last longer, and have much more torque or pulling power than a petrol engine. The only disadvantage to a diesel is the fact that it is more costly to build than a gasoline engine.


What cancels torque?

The tail rotor cancels out torque in a helicopter generated by its engines and main rotor. Without this, the helicopter would simply spin in a circle and be complete uncontrollable.


What is the working principle of diesel engine?

Diesel engines work much in the same way as any other internal combustion engine. They require the same 4 things to run; fuel, air, ignition, and compression. The main difference is that a diesel engine does not have sparkplugs, which are used in gasoline engines to ignite the fuel. Diesel engines instead use high cylinder compression to press the mixture of fuel and air into as small of an area as possible. This compression causes heat in the cylinder, which causes the fuel to ignite and push the piston back down, causing the crankshaft to rotate, which power's vehicle's motion. Some diesel engines use "Glow Plugs", to pre-heat the cylinder head, which help the engine start when cold.
