Engine efficiency is increased though compression ratio by allowing a more thermodynamic energy to be converted into mechanical energy. Energy transfer is the key to efficiency.

What is the compression psi of a compression ratio of 16.2?

There is no direct connection between compression ratio and pressure. Ratio is a mathematical calculation of the cylinder volume from bottom center to top center. Actual cylinder pressure will depend on the volumetric efficiency of the engine. Factors the affect volumetric efficiency include rpm, intake design, throttle plate size, amount of restriction in the exhaust, size of the valves, shape of piston and combustion chamber.

What is the function of a cool air intake?

The cool air intake is mainly to keep the engine oxygenated and allows for a higher performance and efficiency of the engine. This also keeps the engine from over heating. Its mostly performance based.

No it would not. Transmission performance does not affect the engine. But engine performance does affect the transmission.

Can you put a 1 barrel carb on a Chevy 305 engine?

with adapters you could but it would probably lack performance and efficiency.

Why to use turbocharger?

A turbocharger uses exhaust gases to drive a turbine which forces more air into the cylinders, allowing for more fuel to be burned per cycle, resulting in increased horsepower. Besides performance, a turbocharger can also be used in a low-displacement engine (e.g. 1.6L) to match the performance of a larger engine (e.g. 2.5L), resulting in better fuel efficiency for similar performance. In conclusion, a turbocharger improves performance and fuel efficiency.

How do you increase thermal efficiency in converting heat energy to mechanical energy eg in internal combustion engine or gas turbine is there any device to improve thermal efficiency?

The first step would be to insulate the system to decrease heat loss then increase the compression ratio of air/fuel mixture as in the ic engine The first step would be to insulate the system to decrease heat loss then increase the compression ratio of air/fuel mixture as in the ic engine
