In a single action steam engine, high pressure steam is introduced into a chamber formed by the cylinder and the piston. The steam entering the cylinder has two jobs to do:
- Push the piston down in the cylinder, which turns the crankshaft, and so provides mechanical energy for powering a locomotive or steamship, or doing other useful work,
- Overcome the frictional loss, mostly of the piston rubbing against the cylinder wall as it is pushed down by the steam and then returned to the top through the inertia of the flywheel. This effort does not provide any useful work and is considered wasted energy.
In a double action steam engine, once the steam in the cylinder has pushed the piston down to the bottom of the stroke, additional steam is introduced at the other end, which pushes the piston back up to the top of the stroke.
The result is that there are two power strokes, but only the same frictional energy loss as in a single action steam engine. In effect, you have cut the frictional loss in half for each power stroke, and this increases the efficiency of the engine, and therefore also increases the fuel economy of the system.

What is the purpose of the inlet valve in a diesel engine?
The inlet valve in a diesel engine controls the flow of air into the combustion chamber during the intake stroke. Its primary purpose is to allow the engine to draw in the necessary air for the combustion process, which is essential for efficient fuel combustion and engine performance. Proper timing and operation of the inlet valve are crucial for optimizing power output and fuel efficiency. Additionally, it helps in ensuring that the engine runs smoothly by maintaining the correct air-fuel mixture ratios.

industrial
Do 22 inch wheels affect the performance and fuel economy on a 07 charger?
The size of the wheel itself does not affect performance or fuel economy, but the height of the tire does. A taller tire will decrease performance, but increase fuel economy. A taller tire would have a larger circumference, and therefore decrease the engine speed (RPM's) leading to the improved economy. On the other hand, a taller tire also acts to reduce the car's ability to accelerate (like changing the gear ratio). Also, the speedometer won't be accurate any more.
What is the fuel economy on a Ford Transit t260?
The fuel economy of the Ford Transit T260 varies depending on the engine and configuration, but it typically averages around 14 to 18 miles per gallon (mpg) in combined city and highway driving. The 3.5L V6 engine is common in this model, and factors such as load, driving conditions, and maintenance can affect overall efficiency. For precise figures, it's best to refer to the specific model year and engine specifications.
