Sentences with phrase «intake charge»

Turbochargers compress intake charge to aid in combustion giving equipped vehicles more power and greater fuel efficiency.

The VGT is able to operate at a high peak boost pressure of 1.7 bar and provides a dense intake charge in combination with air - to - air intercooling.

In additional to providing a cooler air intake charge, the hood scoop provides a ram air effect at cruising speeds, reducing turbocharger lag and improving overall engine performance while the vehicle is in motion.

The lean condition combined with a late spark left some of the lean over oxygenated intake charge still burning when his exhaust valves began to crack open.

In older engines the combustion chambers may be inefficiently shaped which doesn't allow the entire intake charge to burn.

To provide a high - tumble intake charge that further enhances combustion efficiency, both the intake port and piston crown have special designs.

Key to the engine's performance is a high - pressure, common - rail fuel system allied to closed - loop combustion control and strong intake charging from a variable geometry turbocharger (VGT).

Cosworth engine upgrades: Pistons, Rods, Turbo, Intercooler, Intake Manifold, Intake charge design, Fuel system, and Engine Management system

Two air - to - water intercoolers reduce compressed air temperature for maximum intake charge density.

Tubes that are too small will create exhaust flow resistance which the engine must work to expel the exhaust gas from the chamber, reducing power and leaving exhaust in the chamber to dilute the incoming intake charge.

Since the fuel injection (on DDI) injects directly into the combustion chamber, the cleaners don't get to properly wash the valves (I've heard from a GM engineer that there is some back - wash of intake charge that cleans the intake valves), it is not an ideal situation.

Cool air is key for performance, especially for the engine and to provide a dense intake charge to feed hungry turbochargers.

This enables high power, improved fuel atomization and efficient mixing with the air intake charge.

I'm familiar with the use of air intercoolers / charge air coolers to cool the intake charge (usually on turbocharged engines).

But this BMW engine seems to use liquid to cool the intake charge.

To most efficiently cool the intake charge, four water - to - air intercoolers are used.

Additionally, excessive valve overlap is tuned into the system to ensure the intake charge flushes the combustion chamber of exhaust gasses.

The supercharger is still a four - lobe, Roots - type unit compressing the intake charge to a peak pressure of 9 psi, but thanks to a revised induction system, the ZL1's blown small - block sends an extra 24 hp and 5 lb - ft of torque to the rear wheels compared with the CTS - V for a total output of 580 hp and 556 lb - ft.

This is where components like cool air intakes (to start with the lowest possible starting point) and intercoolers (to try to lower the temperatures of the intake charge after the turbo) become important.

Running rich doesn't guarantee efficient combustion, in particular fuel cools the intake charge, too much fuel may cool the combustion, foul sparkplugs, etc..

If there was enough pressure, it is conceivable there could be some intake charge forced out of the exhaust port if there was enough overlap.

Because of this, at low RPM, when VTEC is not engaged, one of the two intake valves is allowed to open only a very small amount due to the mild cam lobe, forcing most of the intake charge through the other open intake valve with the normal cam lobe.

The cooling process increases the density of the intake charge, promoting more thorough combustion with reduced emissions

This induces swirl of the intake charge which improves air / fuel atomization in the cylinder and allows for a leaner fuel mixture to be used.

As diesel engine speeds and loads increase, the higher cylinder temperatures after compression of the intake charge result in increased injection and ignition efficiency due to increased fuel atomization.

Cooled exhaust gasses are also introduced into the intake charge to make the mixture more dense and powerful.

This 12 Valve mode results in swirl of the intake charge which increases combustion efficiency, resulting in improved low end torque and better fuel economy.

Based on the 911 Turbo, the GT2 receives larger air intakes that feed two hopped - up variable - geometry turbochargers, which in turn send the intake charge into a new expansion manifold.

The big output is courtesy of a new twin - scroll turbocharger that comes with a slightly larger compressor wheel, and the intake charge is chilled by an oversized intercooler for more efficiency.
