what is the difference between flat top pistons and dished pistons?

But this comes with a bit of a weight penalty versus a flat-top piston, so the dished piston is more suitable for large-displacement, low-rpm engines. All of this makes the flat-top piston preferable for most performance engines, particularly those that don't use hemispherical combustion chambers.

The major and usual visual difference is aircraft piston engines are air cooled (lighter weight, mechanically dirt simple) and flat rather than V designed. While an automotive engine can produce more power than a typical aircraft engine of the same displacement, they are far heavier.

These products can be fine. Top Knobs has some cast zinc hollow products where the intricate design of the knob can only be created by using cast zinc. For such products we use a high-grade cast zinc alloy that is thicker, stronger, and long-lasting. Finish is just as important as the metal used.

The difference is in the arrangement of the cylinders. A straight six has all of the cylinders lined up one after another, all facing the same way. It is a long engine. ... A V6 engine usually refers to any V angle of less than 180 degrees.

The main difference is where the engine sends power. In FWD vehicles, the engine only powers the front axle, whereas, in AWD vehicles, the engine powers both front and rear axles. ... Rear-wheel drive systems (RWD) enable better handling in performance cars by distributing weight more evenly.

The most noticeable difference is the shape of the cylinder, which is where the pistons are located. In a single-stage pump, both pistons are the same size so both sides of the cylinder have the same physical dimensions. In a two-stage pump, there is one low pressure (large) piston and one high pressure (small) piston.

The main difference between a vented and unvented water storage cylinder is that an unvented hot water cylinder takes its water supply directly from the mains. You can get hot water out of an unvented cylinder at a much better pressure than a traditional vented cylinder as it is pressurised.

Piston and Piston Rings. A piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces produced during the combustion process. The piston acts as a movable end of the combustion chamber. The stationary end of the combustion chamber is the cylinder head.

They only differ in the components they carry. A short block package typically includes the engine block, crank and pistons. ... A long block engine has all the parts of the short block package. To the skeleton that is the short block, it adds a cylinder head, camshaft and valve-train.

In a piston engine, the main bearings are the bearings which hold the crankshaft in place and allow it to rotate within the engine block. Main bearings are usually plain bearings or journal bearings, held in place by the engine block and bearing caps.

The main difference is where the engine sends power. In FWD vehicles, the engine only powers the front axle, whereas, in AWD vehicles, the engine powers both front and rear axles. ... It is a two-wheel drive system that pushes the car from the rear axle.

Curly Tops have a darker color, which could mean they are made with more cocoa or made with cocoa beans with a darker roast. They also have a smoother texture. Flat Tops, on the other hand, have a lighter color and harder texture. They don't easily melt but are malleable when you handle them.

Difference Between Batter and Resonant Drumheads The batter head (Sometimes referred to as the “top head”) is the part of the drum that you actually hit. The resonant head is the head of the bottom that responds to the batter being struck.

LQ9 vs LQ4. The ONLY difference between an LQ4 and LQ9 is the piston! There are NO embossed or etched exterior markings on the block or heads to indicate one over the other. There is a paper sticker applied to the back of the drivers-side head at time of manufacture that indicates the type of engine.

Both are standard, no work done to either the heads or to the block. Firstly the VN heads will flow much more than your 253. If you standered heads were ported to the limit they would flow close to the same.

Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. The 4-stroke engine is also much quieter, a 2-stoke engine is significantly louder and has a distinctive, high-pitched “buzzing” sound.

Forged pistons are more expensive compared to conventional cast pistons, and are decidedly more durable in terms of shatter resistance when exposed to extreme temperatures inside the combustion chamber. This does not mean that cast pistons are inadequate. In fact, they are more than enough for most applications.
