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

If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.

How can you increase the mechanical advantage of a pulley?
Increase the distance on the machine. :) XD
Why do refrigerators have magnetic doors?
Increase sealing efficiency.
What can be done to increase the efficiency of the machine?
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.

What is the purpose of the turbine in a jet engine?
To drive the compressor section, therefore 'doing work' on the air to increase the efficiency of the combustion process.
Why boost pressure required?
boost pressr is required to increase the power or efficiency of engine. because due to boost pressr we get better fuel combustion.
What would happen to a pulley system if the load were increased?
Ideal mechanical advantage is the mechanical advantage when there is no friction. It is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load. But actual mechanical advantage will be less than this ideal mechanical advantage due to friction. In other words the efficiency will be less than 100 %. If the efficiency is 80%, it implies 20% is wasted due to friction while lifting a load. If we increase the load the friction also increases and hence the efficiency will decrease with the load.
How efficient is the combustion engine?
The efficiency of a internal combustion engine varies with size, speed range, compression ratio etc. Diesel engines use higher compression ratio and operate without throttle control, therefore their efficiency is higher than a equivalent Otto engine. Large marine (read ship engines) or stationary diesel engine: 50% Heavy duty diesel engines for marine, stationary and vehicle applications (trucks): 40% Light duty diesel engines (cars): 30-35% Gasoline engines: 20-25% + a few % for newer engines The numbers mentioned above are maximum efficiency, not pedal to the metal efficiency. Please note that the thermal efficiency of a engine will increase if the combustion chamber surface decrease(!). Higher revs leads to higher forces acting on the piston rings and therefore higher frictional losses, in other words: the mechanical efficiency decreases with increased speed.

How do you increase gas mileage on a 2000 Volkswagen super beetle?
There are a few ways to increase gas mileage but the most effective is the use of fuel infusion. Fuel Infusion is a powerful fuel catalyst that improves the efficiency of the combustion process in your car's engine.
How do you increase the efficiency of a engine?
Lower it!
What leads to technology?
an increase to efficiency
When you increase the height of a ramp which increases the angle does the efficiency for kinetic energy increase of decrease?
The energy efficiency increases as the angle increases.
