Sentences with phrase «allowing higher compression»

Injecting fuel directly into the combustion chamber offers a cooling effect allowing a higher compression ratio and optimized combustion efficiency.

The production M4 GTS's twin - turbo 3.0 - liter inline - six will be fitted with a water - injection system, which cools down the intake temperature thus allowing a higher compression ratio or increased turbocharger boost for more power.

The production M4 GTS will be fitted with a water - injection system, allowing a higher compression ratio or increased turbocharger boost for more power.

From our side, I think the number - one move to allow higher compression ratios will be the development of water injection to reduce combustion temperatures — it's all about controlling knock or pre-ignition.

Additionally, a dual fuel - injection system that utilizes both port and direct injection optimizes efficiency and allows high compression (11.8:1) for power and efficiency.

It allows a high compression of 12.5:1, for increased power and efficiency.

When Charles F. «Boss» Kettering developed fuels that would allow higher compression engines to operate without knocking, it was to maximize fuel efficiency in the face of a gasoline shortage, not to herald the beginning of the muscle car era.

The FSI direct fuel injection system allows a high compression of 12.5: 1.

If you are looking for pregnancy compression stocking that offer warmth and comfort while also allowing a high level of ventilation, these could be the ideal choice.

«Because we pre-compressed the water, there is less shock - heating than if we shock - compressed ambient liquid water, allowing us to access much colder states at high pressure than in previous shock compression studies, so that we could reach the predicted stability domain of superionic ice,» Millot said.

But the fibres in compression garments not only allow your body to withstand high temperatures to a greater extent, but the moisture - wicking technology also prevents fabric mildew and heat exhaustion.

However, all other variables being held constant, using a high octane fuel allows you to design a higher compression engine to take advantage of that octane number.

VC - T, for Variable Compression - Turbocharged, can raise or lower the stroke of the pistons allowing the compression ratio to vary between 8:1 and 14:1 — providing performance benefits at low compression and efficiency improvements at high compression.

The engine will adopt a lower compression ratio under hard acceleration or heavy loads to allow the turbocharger to deliver maximum boost, and move to a higher compression ratio on light throttle to allow for fuel - efficient lean - burn running.

They accept that higher - octane fuels will allow us to use higher compression ratios to improve combustion efficiency.

The higher compression ratio in diesels means they are harder to start, but once they are running the energy expended in compressing air is regained during the expansion stroke when the compressed air is allowed to «spring» back, so the higher compression ratio causes negligible engine braking via energy being lost as friction and heat of compressed air to engine block.

Premium fuel will allow more spark advance, higher compression ratio, or both.

Add to that the details we were being provided by the engineer about the high - tech, fragile - sounding stuff inside the engine — the «i - VTEC,» a system of «intelligent» valve timing that allows all 16 valves to open and close at precisely the correct time, for precisely the correct duration; a compression ratio of 11:1, more like a race - car engine than a passenger car; and a fuel injection system so sophisticated that rocket scientists would be scratching their heads.

The cooling jets also allow for a higher compression ratio for better engine efficiency and faster engine oil warm - up on cold starts, also improving fuel economy.

The fuel also has a cooling effect on the combustion that allowed the M engineers to endow the engine with a high compression ratio: yet another technical attribute that contributes to both performance and efficiency, while also reducing exhaust emissions and even having a positive effect on how the engine sounds.

Early intake valve closing — well before the bottom dead center is reached — lowers the pressure, allowing a high, efficiency - boosting compression ratio.

The charged air is water - cooled — rather than air - cooled in the Porsche — which combined with a slightly higher compression ratio, allows it to eke out a smidge more power.

The cooling effect of fuel injected directly into the cylinder allows the incorporation of the power - increasing effects of a higher compression ratio without engine knocking.

This was achieved through a combination of high compression ratios, improved exhaust design, and by a new style of turbocharger that allows the turbo to spin faster at lower engine rpms.

The cooling effect of the injected fuel also allows for a higher compression ratio than might otherwise be possible.

Requiring a higher temperature allows an engine to run more compression without risking detonation, or knock.
