The beam of the engine had a vertical 'plug rod' hung from it, alongside the cylinder. Adjustable blocks or 'tappets' were attached to this rod and as the beam moved up and down, the tappets pressed against long levers or 'horns' attached to the engine's valves, working the cycle of steam and injection water valves to operate the engine.

High heat release and pressure rise rates contribute to engine wear. Autoignition is difficult to control, unlike the ignition event in SI and diesel engines, which are controlled by spark plugs and in-cylinder fuel injectors, respectively. [6]
The power produced by an engine increases with the engine's RPM to a maximum, then falls away. The point of maximum power is somewhat lower than the absolute maximum engine speed to which it is limited, the "redline". A car's speed is limited by the power required to drive it against air resistance, which increases with speed.
1928-1942 Indian Four straight-4 motorcycle engine. Straight engines (also known as "inline engines") have all cylinders aligned in one row along the crankshaft with no offset. When a straight engine is mounted at an angle, it is sometimes called a "slant engine". Types of straight engines include: Single cylinder; Straight-2, also known as ...
This significantly reduces engine performance, since the circular piston rings are unable to properly seal against the oval-shaped cylinder walls. The amount of sideways force is proportional to the angle of the connecting rod, therefore longer connecting rods will reduce the amount of sideways force and engine wear.
If you have an inherited intolerance to alcohol, a mutated gene could be the culprit. An at-home DNA test could detect whether you have the mutation, but doctors say there could be some drawbacks.
Boeing has laid off hundreds of additional employees in Washington state and California as part of planned cuts that will eventually reduce the company's workforce by about 17,000. Nearly 400 ...
High school football enthusiasts who want to place a bet on a big game have no choice but to turn to an offshore site. Accepting a wager on high school sports is outlawed in Nevada and other U.S ...
