Inside a diesel engine's cylinder, compressed air raises the temperature to ignite injected fuel, and the resulting force drives pistons to power the vehicle's main gears. Chief to this combustion ...

While diesel engines don't need spark plugs, they do need air ventilation for proper combustion. This is a problem for vessels traveling underwater, such as submarines. Yet diesel submarines exist and ...

Submarines are a marvel of modern engineering, and the realities of operating one (as well as working and living on one) are ...

Submarines are hard to find. They exploit ocean depth, acoustic complexity, and thermal layers to maintain low observability and high survivability. Diesel-electric submarines are especially quiet at ...
