If you have read How Car Engines Work, then you are familiar with the concept behind the four-stroke engine. Car engines arrange pistons in three typical patterns, as shown here: (Click on image to see animation) V - The cylinders are arranged in two banks set at an angle to one anoth...
Most cars on the road today use an internal-combustion engine to burn petroleum-based fuel, generate heat, and push pistons up and down to drive the transmission and the wheels. Electric cars work an entirely different way. Instead of an engine, they rely on batteries that feed electric ...
It is used to start the engine when it has been shut down for maintenance or other reasons. There are two types of jet engine starters: axial piston pumps and rotary piston pumps. An axial piston pump is operated by one or two rotating pistons that are connected to each other inside an...
阅读理解There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal-combustion engine(内燃机) has something to do with burning fuel,expanding gases and pistons(活塞) being driven. For people should have some ...
Automating these processes can help reduce costs as it eliminates repetitive and needlessly prolonged manual work labor. Additionally, predictive analytics help automotive businesses better understand their consumers so they can preemptively adjust their inventory and schedules to prepare in advance for change...
In a piston engine, that pressure is contained in the cylinders and forces pistons to move back and forth. The connecting rods and crankshaft convert the reciprocating motion of the pistons into rotational motion that can be used to power a car. In a rotary engine, the pressure of combustion...
The big engine is heavier than the small engine, so the car uses extra energy every time it accelerates or drives up a hill. The pistons and other internal components are heavier, requiring more energy each time they go up and down in the cylinder. ...
within the engine itself. Fuel, typically a mixture of air and a hydrocarbon, is ignited inside a combustion chamber, resulting in controlled explosions. These explosions generate high pressure and temperature, which drive the movement of pistons, ultimately converting the energy into mechanical work....
energy that drives the engine's pistons. It's pretty obvious that the steam leaving the chimney still contains quite a bit of energy, which is one reason why engines like this are so very inefficient. Steam turbines usefully capture much more of the energy in steam—and are much more ...
An engine compresses fluids (air-fuel mixture), which ignites to push the piston downwards. The piston, in turn, moves the crankshaft. In two-stroke engines, pistons also serve as inlet and outlet valves. Thus, engines, unlike pumps and compressors, derive motion from the combustion of compr...
