Absolutely – if you design it for no gravity (fuel injection systems are common, use pressurized fuel and oxidizer tanks) and BRING YOUR OWN OXYGEN as well as a way to get it into the engine. Fuel cells however are more efficient, and have been widely used in space for many years.
Can an engine run in space?
Turbine engines and propellers use air from the atmosphere as the working fluid, but rockets use the combustion exhaust gases. In outer space there is no atmosphere so turbines and propellers can not work there. This explains why a rocket works in space but a turbine engine or a propeller does not work.
Would an internal combustion engine run on Mars?
They wouldn’t work. Cars powered by internal combustion engines require air to do the combusting. The atmosphere on mars is too thin and lacking in oxygen to allow any such design to work. Any vehicle that would work by burning fuel would need to carry its own oxygen supply or another oxidizer to work on Mars.
Can an internal combustion engine run without oxygen?
The internal combustion engine in most cars burns gasoline. To do the burning, an engine needs oxygen, and the oxygen comes from the air all around us. … The engine can burn no more gas than the amount of oxygen allows. Any extra fuel would come out of the exhaust pipe unburned.
Can a diesel engine run in space?
If your car is a diesel, it will run. Liquid hydrogen, the fuel that powered the space shuttle’s main engines, could work, says Manuel Martinez-Sanchez, an aeronautics and astronautics professor at the Massachusetts Institute of Technology.
Is space in a vacuum?
Space is an almost perfect vacuum, full of cosmic voids. And in short, gravity is to blame. … By definition, a vacuum is devoid of matter. Space is almost an absolute vacuum, not because of suction but because it’s nearly empty.
How do rockets fire in space without oxygen?
If there is no oxygen in space, how do rockets ignite their engines? Rockets carry an oxidizer, often in the form of liquid oxygen, to burn their engine fuel. That’s the fundamental difference between rockets and jets; the latter get oxygen from the air.
Could a diesel engine run on Mars?
Off the shelf diesels work in the Mars temperature range in Siberia and Antarctica. Custom engines should work fine on Mars. With the electric drive if one electric motor fails you still have the others. Each electric motor can have it’s own battery and power supply unit with cross over to the others if needed.
How does combustion work on Mars?
It’s designed to demonstrate a technology that converts carbon dioxide into oxygen with a process called electrolysis. Mars’ thin atmosphere is 95 percent carbon dioxide, but sending anything back into space requires fuel, and burning that fuel requires oxygen.
Can cars drive Mars?
Like a car on Earth, the rover uses its odometer to click off the distance it has traveled. … But, unlike cars on Earth, the rover doesn’t drive on smooth, paved roads. The rover moves on rocky and sandy martian terrain. The rover wheels might have a hard time grasping onto the loose-gravel ground.
Why are hydrogen engines a bad idea?
Hydrogen fuel cells have bad theoretical and practical efficiency. Hydrogen storage is inefficient, energetically, volumetrically and with respect to weight. … It has a horrible well-to-wheel efficiency as a result. Easy ways to get large quantities of hydrogen are not ‘cleaner’ than gasoline.
What are the four stroke cycles in a four stroke engine?
An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust.
What does internal combustion engine mean?
Internal-combustion engine, any of a group of devices in which the reactants of combustion (oxidizer and fuel) and the products of combustion serve as the working fluids of the engine. Such an engine gains its energy from heat released during the combustion of the nonreacted working fluids, the oxidizer-fuel mixture.
Do diesel engines get louder with age?
Older diesel engines are usually much louder than new engines, because newer technology has enabled the engines to run much softer. You can help reduce the amount of noise the engine makes by making a few modifications to oil, fuel and insulation.
Do diesels need to be driven hard?
No, diesels do not need to be driven hard. You should drive a diesel powered vehicle just like any other vehicle. Why do diesel engines have engine braking when they don’t have an ability to restrict air flow? Engine braking only works BECAUSE they do not restrict inlet airflow.
Is it good to drive a diesel hard?
Driving a diesel engine hard will produce less soot per kWh of useful work. … Driving a diesel hard will also use more fuel. Use the torque which is what a diesel is about and let the DPF sort itself out as necessary, it works for most people like that.
