Sentences with phrase «achieved by the combustion»

This is achieved by the combustion of solid, liquid or gaseous propellant, containing oxidiser and a fuel, within a combustion chamber at high pressure.

Not exact matches

To reach hypersonic speeds, current systems will need to be replaced by what engineers call «air - breathing» systems, which could be achieved by scramjets (also called «supersonic - combustion ramjets»).

In order to achieve cost parity with an internal - combustion engine, battery costs would have to be cut by more than two - thirds and fuel costs would have to more than double today's level.

@Paulster2 Theoretically by igniting the fuel sooner a higher combustion chamber pressure can be achieved at the moment of the power stroke.

The turbocharged unit continues to use pre-chamber ignition, whereby a small amount of fuel is ignited before the main engine chamber in order to achieve more uniform combustion, but Renault is yet to adopt the split turbo setup pioneered by rival Mercedes.

Stable combustion is achieved by using less fuel than conventional direct injection engines which have an air - fuel ratio of 40:1.

This has been achieved within the new Auris petrol engine range through the use of high, 11.5:1 compression ratios, Valvematic, the refinement of intake port and combustion chamber design and piston cooling by oil jet.

This is accomplished by achieving rapid combustion due to higher tumble air flow.

By precisely controlling fuel injection and improving the exhaust valve's opening and closing mechanism, the SKYACTIV - D diesel engine has achieved breakthroughs to resolve longstanding issues encountered in low compression ratio engines, such as poor start capability and lower combustion stability when the engine is cold.

The use of AVCS contributes to higher power output, while fuel economy is also achieved by improving combustion efficiency through the optimized timing of valve openings and closings.

Nissan is committed to a holistic approach to achieving zero - emission mobility by making internal combustion engines more efficient and putting more advanced technologies into our electric vehicles.

A time came when we learned to make machines and achieved great advances by enjoying the leverage that comes when an internal combustion engine does the pushing rather than our legs.

And although such constraints are not directly connected to climate change driven by profligate combustion of fossil fuels, what humans achieve is a combination of genetic and environmental limitations.

Using a 20 - year GWP for methane, the 50 % goal would achieve reductions of over 2,300 MTCO2e (the equivalent of India and the EU's combined CO2 emissions from coal combustion in 2012) and the 75 % goal would reduce emissions by around 3,400 MTCO2e (nearly as much as all CO2 emissions from coal combustion from OECD countries in 2012).

To achieve climate stabilization in the longer term, policies are needed to address combustion emissions through carbon capture and storage or by other means.

Hybrid - electric trucks achieve increased fuel efficiency by combining a conventional internal combustion engine with an electric motor, batteries, and braking - energy capture (known as regenerative braking).
