Why generators are not used in cars?
They’re common. The reason all cars don’t do that is because hauling a generator and an engine and a fuel source around is wasteful. It’s heavy, and it’s a lot of moving parts, all of which can and will fail. Much simpler to just have a motor and leave it at that.
Do train engines run on electricity?
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking.
Can engines work without electricity?
Yes you can run an engine without any electricity, and if its properly designed, then a diesel hydraulic series hybrid is more efficient then an electric hybrid. Even bright lights can be used without electricity. Gas mantle with fresnel lens would work just fine. No, a gasoline engine needs sparks for combustion.
How do engines generate power?
Combustion engines employ the expansion of hot gases to push a piston within a cylinder, converting the linear movement of the piston into the rotating movement of a crankshaft to generate power. In diesel engines, air is compressed until the temperature rises to the auto-ignition temperature of the fuel.
What fuel does rail use?
Diesel fuel
Diesel fuel has become the preferred fuel for railroad locomotive use due to its lower volatility, lower cost, and common availability. The diesel engine (A) is the main component of the diesel-electric locomotive.
Why does an engine need electricity?
They use electrical starting system to heat up the engine and initiate the fuel ignition process.
Will a diesel run without a battery?
it will run without an alternator….but not without a battery. you need to keep 12 volts going to the fuel stop solenoid on the injection pump. As long as you have that you’re good to go.
How does E-Power work on electric cars?
With e-Power, an electric motor drives the car’s wheels, using energy from an onboard battery pack. When the battery pack’s charge gets low, the gasoline engine turns on to recharge it. The car can also be plugged into an electric vehicle charger, to help minimize use of the gasoline engine.
How many amps does a diesel train engine produce?
The diesel engine makes 3,200 horsepower, and the generator can turn this into almost 4,700 amps of electrical current. The four drive motors use this electricity to generate over 64,000 pounds of thrust. There is a completely separate V-12 engine and generator to provide electrical power for the rest of the train.
What makes an electric motor so efficient?
As with an internal combustion engine, electric motors also have what Nitz calls “islands of efficiency” — certain speeds and loads at which the motors operate most efficiently. And engineers can tune that based on the vehicle.
How much power does a locomotive engine use?
This 270,000-pound (122,470-kg) locomotive is designed to tow passenger-train cars at speeds of up to 110 miles per hour (177 kph). The diesel engine makes 3,200 horsepower, and the generator can turn this into almost 4,700 amps of electrical current. The four drive motors use this electricity to generate over 64,000 pounds of thrust.
