Sentences with phrase «decreased efficiency of the engine»

Not exact matches

The authors found that their heat engine model only yields high efficiency and output power when the number of photons involved is small; accordingly, its efficiency and power output rapidly decrease as the number of photons increases.

When complemented by the precision of the engine's valvetrain, that separation leverages exhaust scavenging techniques to optimize gas flow, which decreases exhaust gas temperatures, improves turbine efficiency and reduces turbo lag.

The goal of performance exhaust headers is mainly to decrease flow resistance (back pressure), and to increase the volumetric efficiency of an engine, resulting in a gain in power output.

If the U.S. were instead to use that natural gas to generate electricity as part of a portfolio with renewable sources of electricity, the analysis shows that «if the entire vehicle fleet were converted to electric vehicles and high efficiency natural gas combined - cycle power plants were used to generate all the additional electricity required, the increase in natural gas demand would be significantly less» than if the entire fleet was burning natural gas in its combustion engines — roughly a decrease in natural gas usage of 19 billion cubic feet per day.

Wear and tear on these items can decrease the fuel efficiency of your engine.

If you travel with a load secured to the roof of your vehicle, make sure it is situated in the most aerodynamic way to reduce wind drag, which causes your engine to work harder (and decreases your fuel efficiency).
