Some carbureted engines have low-pressure fuel pumps: they are typically designed only to overcome a loss of suction in the fuel line near the engine due to fuel evaporation in hot weather, to supply sufficient fuel to maintain stoichiometric combustion under heavy load with wide-open throttle, or a combination of the two. Fuel demand is low at ...
By replacing some of the fresh air intake with inert gases EGR also allows the engine to reduce the amount of injected fuel without compromising ideal air-fuel mixture ratio, therefore reducing fuel consumption in low engine load situation (for ex. while the vehicle is coasting or cruising).
Another method of fuel staged combustion is fuel biasing. In fuel biasing, combustion is staged by diverting fuel from the upper-level burners to the lower ones or from the center to the side burners. The aim is to create a fuel-rich lower or central zone and a fuel-lean upper or side zone in order to achieve complete burnout.
The EPA calculated that new trucks would save operators a total of $3.5 billion in fuel and other costs from 2027 to 2032, paying for themselves in two to four years.
Parasitic load or parasitic loss may refer to in internal combustion engines, it refers to devices that take energy from the engine in order to enhance the engine's ability to create more energy or convert energy to motion. in electricity production, it is any of the loads or devices powered by the generator, not contributing to net electric yield
The Environmental Protection Agency proposes new cuts to heavy vehicle emissions, targeting those chemicals that produce lung-damaging smog.
This is done to increase fuel efficiency while under varying loads. Variable compression engines allow the volume above the piston at top dead centre to be changed. Higher loads require lower ratios to increase power, while lower loads need higher ratios to increase efficiency, i.e. to lower fuel consumption.
Military drivers will now get specialised training in preparation for their possible deployment, ministers announced.
