What is the Significance of brake thermal efficiency?

It is used to evaluate how efficient an engine converts the heat from a fuel to mechanical energy.


How VVTI works?

It is a variable valve timing innovations from toyota, where in power and fuel efficiency can be optimized by varying the timing of the camshaft with respect to the crankshaft of an engine,by retarding or advancing the camshaft by a certain phase angles.A conventional engine has it's camshaft rotate half the crankshaft rotation and the performance of a such engine would be in it's peak efficiency for a single speed only.Engineers developed a technology to overcome this in-efficiencies by introducing variable valve timing where camshaft rotation can advance or retard with respect to the crankshaft,hence optimising performance and fuel efficiency.


Advantages and disadvantages of camless engine?

low power consumption, high efficiency,more output power are some of the advantages of camless engine by SHEKAR...VCE COLLEGE,MECHANICAL ENGINEERING III YR


What are the names of the jet turbo engines?

The term jet engine is loosely referring to an internal combustion airbreathing jet engine. A turbo, or turbocharger is a device, usually fitted to a car or truck, to increase an engine's efficiency by forcing more air into the combustion chamber. I can see how you might have confused the two, as they are both primarily based on a turbine-driven design.


What are the advantages of free turbine engine over gas turbine engine?

A gas turbine engine will usually yield more power by weight than a piston engine. Main downside is that it can't be throttled very well. Energy efficiency isn't all that good to start with, and will drop right down if it has to be operated outside its optimum range.

Hemi Engine?

The term "hemi engine" refers to an engine with a hemispherical combustion chamber. The word "hemi" is short for hemispherical, and it describes the shape of the combustion chamber in the cylinder head of the engine. This design is known for its efficiency in allowing air and fuel to flow in and out of the chamber, leading to improved combustion.


What was discovered by James watt?

That the efficiency of a Steam Engine could be improved by condensing the exhaust steam.


Diesel engine loss of rpm under load?

yes because load affect the efficiency of engine , it can be improved by increasing the supply of oil in governer.


How many units or KVA of electricity can be produced with one liter of diesel?

In a diesel engine connected to a generator with a 23% engine efficiency, 1 liter of diesel should produce nearly 2.7 kilovolt-amperes. More with improved engine efficiency.


Did James watt invent the steam engine by accident?

No, he improved on Newcomen's design for pumping engines.


What is the combustion efficiency in an automobile engine?

It varies somewhat depending on engine design, but a gasoline engine is approximately 30% efficient due to heat, mechanical loss, etc. Despite modern engines getting about 98-99% efficiency out of the gasoline.


What didJamesWatt invent?

Watt developed the concept of Horsepower and the unit of power the Watt. He did not invent the steam engine but did make significant improvments to the Newcomen steam engine. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.


What type of people used the Babbage Engine?

Nobody, because neither his Difference Engine #1 design nor Analytical Engine design nor improved Difference Engine #2 design were ever built in his lifetime.Two copies of his Difference Engine #2 design were built by the London Science Museum in 2002, 153 years after it was designed. They were used only as museum exhibits.


What are the benefits of using castrol edge motor oil?

Castrol Edge's motor oils provide cars with excellent protection in various driving conditions and temperatures. They also maximize engine performance, improve engine efficiency, and in turn increase savings from the improved efficiency.


When was the steam engine improved?

the steam engine was improved in 1769.
