What is the efficiency of an engine that gives off 70 percent thermal energy?
It is not a good efficiency engine.
How do you increase the efficiency of a engine?
Lower it!
Why efficiency of carnot heat engine is always greater than that of an actual engine?
The efficiency of a Carnot engine is theoretically always greater than that of an actual engine. The fact that it is impossible to build a thermodynamically reversable engine, which is one of the variables necessary to calculate its superiority to a real heat engine, makes the theorum practical for assessing a real heat engines efficiency only.
What is maximum efficiency of stirling engine?
78%
Does cutoff ratio affect the engine efficiency?
yes

compare the two stroke and four stroke engine in power output and thermal efficiency?
Why diesel engine trains more used compare to steam engine trains?
Efficiency and cost. The maintenance of a steam engine can be very costly as compared to a diesel engine as well.
What is thermal efficiency of petrol engine?
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
What is the efficiency of a gasoline engine?

What is efficiency of an engine that gives off 70 percent thermal energy?
It is not a good efficiency engine.
Why efficiency of heat engine is more in winter as compare to summer?
Because a thermal engine efficiency is directly linked to the difference of the temperature of the gases involved .As the gasoline burns at a set temperature , the lower winter temp helps to widen the temp differential between the ignited gasoline and exaust. Unfortunatley the colder air is more dense and generate more drag than in summer , more than negating the increased engine efficiency. To put it in rough numbers , you may get 0.5% more engine efficiency but you lose some 4% more to extra drag.
What is the efficiency of an engine that gives off 70 percent thermal energy?
It is not a good efficiency engine.
What services would SEO specialists offer?
Search-engine optizimation specialists better known as SEOs are charged with the responsibility of ensuring the success of search-engine optimization and conversion rates. They are in a sense similar to marketers who analyze the market for efficiency and needs and wants.
What is the formula for calculating the efficiency of a heat engine and how is it used in determining the performance of the engine?
The formula for calculating the efficiency of a heat engine is Efficiency (Work output / Heat input) x 100. This formula is used to determine how effectively the engine converts heat into useful work. A higher efficiency value indicates that the engine is more effective at converting heat energy into mechanical work, while a lower efficiency value indicates that more heat energy is wasted. By calculating the efficiency of a heat engine, engineers can assess its performance and make improvements to increase its efficiency.
Which heat engine has more efficiency?
Carnot's heat engine has more efficiency then the other heat engine but it is assumption. Is is not real. RGUKT IIIT NUZVID: N091528
With increasing temperature of intake air IC engine efficiency?
as intake air temperature increases it lead to decreas in i.c engine efficiency. as engine efficiency is ratio of difference in intake and outlet temperature to intake temperature.
Is it true that thermal efficiency of a diesel engine equals indicated thermal efficiency - brake thermal efficiency?
no
