How to Increase Compression Ratio of Engine for Improving Power

Many factors involved in the compression test, like the head gasket and other parts of the machine, come into action. It also will suffer a reduction in power and fuel economy (see fuel injection and compression effect part). Severe leakage past the piston rings can allow the oil to get into the combustion chamber and foul the spark plugs.

Design of An Automotive Differential With Reduction Ratio Greater Than 6

This is because designing an automotive differential with a reduction ratio greater than 6 may lead to a bulky design which isn't feasible to position with the limited space available. Furthermore, increasing the size of the differential may lead to excessive undesired weight. Most on-road vehicles have differentials with reductions of 3 or 4.

Whether or not so stated, a dB rating is always a ratio either between two sounds, or between one sound and a fixed reference base. To state that a certain pump has an 80 dB noise level means that the ratio between its sound level and that of the selected zero base (0 dB) is 80 on the dB scale. The dB Pressure Scale

How to compute Informaton Gain: Entropy 1. When the number of either yes OR no is zero (that is the node is pure) the information is zero. 2. When the number of yes and no is equal, the information reaches its maximum because we are very uncertain about the outcome. 3.

How to Machine Aluminum: All You Need to Know

6063. This is really similar in function to 6061, but this is more common to see in extrusions. However, it isn't quite as stiff. This makes 6063 a little harder to machine; it's softer and gummier. When you're cutting aluminum extrusions, use really sharp tools, good lubrication, and watch your chip clearance.

How To Calculate Compressed Air Savings - Design World

An additional item has been placed in Figure 3 as Item E for interesting comparison; a 100-psi rated compressor. Its lower specific power number illustrates the savings potential if you operated your air compressor at 100 psi rather than 125 psi. The resulting 9.5% reduction would reduce the total 10-year power costs significantly.

Here's What a Googol-to-One Gear Ratio Looks Like - kottke

This machine has a gear reduction of 1 to 10 a hundred times. In order to get the last gear to turn once you'll need to spin the first one a google [sic] amount around. Or better said you'll need more energy than the entire known universe has to do that. That boggles my mind. You can watch the machine spin for an hour — it's kinda relaxing:

Gear Ratio Calculator for Vehicle with Jackshaft. This calculator determines the top speed of the vehicle with no margin for mechanical, rolling, or wind resistance. These resistance factors could make the top speed slower than the calculation. The amount that the top speed will be reduced by resistance depends on many factors such as the power ...

How do you figure Hp on gear reduction motor?

Worm reducers are also common. In nmerically low ratios like 5 to 1 overall, a worm reducer competes with spur geared and helical reducers quite well in terms of efficiency. As single reduction ratios go higher, efficiency falls off until a 50 to 1 ration worm reducer may be significantly less efficient than a comparable spur geared reducer..

How to Easily Calculate Gear Ratios in Planetary Systems

The motion of planetary gear systems is expressed clearly in the Plantetary Train Equation: -S/R = (ωr-ωa)/ (ωs-ωa). Once this is known, the speeds of the carrier arm, sun and/or ring can be calculated. Multiple series of planetary gear systems can be used to get multiple speeds and directions. Planetary gear systems are used everywhere.

Velocity Ratio Formula The velocity Ratio Formula is represented by 2 equations listed below. 1) Velocity Ratio = velocity of the effort / the velocity of the load = VE / VL .. (1) 2) Velocity Ratio = displacement of the effort / displacement of the load = dE / dL .... (2) Deriving the Velocity Ratio formula as displacement ratio

How to Specify Gearboxes for Motion Control Systems

By multiplying motor torque, a gearbox also effectively scales the motor's ability to control the load. The inertia reflected from the load, J R, is scaled by the gear ratio as: J R = J L / G 2 + J G. where J G is gearbox inertia. The gearbox scales the reflected inertia by the inverse square of the reduction ratio.

How does motor current increase with constant torque but increasing HP

To get the same 100 hp output, the slower machine has to produce more torque. An analogy. Use the 1800 rpm (4-pole) motor. Stick an 1800:1200 ratio reduction gearbox on its output shaft and you reduce the output speed, increase the output torque. But you get the same output power. Using a 6-pole 1200 rpm motor does just that.

Principal Component Analysis (PCA) - Better Explained | ML+

Principal Components Analysis (PCA) is an algorithm to transform the columns of a dataset into a new set of features called Principal Components. By doing this, a large chunk of the information across the full dataset is effectively compressed in fewer feature columns. This enables dimensionality reduction and ability to visualize the separation of classes . Principal Component Analysis (PCA ...

gear ratio change - how does it affect the motor - Eng-Tips Forums

The old speed reduction ratio was 1000:40 or 250:1, so the output shaft torque was 250 x the motor torque (ignore losses for sake of discussion). Now however he is changing the torque requrements via the gearboxes. At 800:40 or 200:1, the output shaft torque will only go up 200 x the motor torque, 20% less than before (200/250) although when he ...
