Sentences with phrase «cylinder at high pressure»

They are produced using sophisticated flow forming technology, in which the outer rim is rolled out over a cylinder at high pressure and high temperature.

Not exact matches

Air starts to flow down the runner into the cylinder until the valve shuts, at which point all that air (travelling at high speed) crashes into the shut valve and creates a relatively high pressure «slug» of air.

There's a new high - pressure injection system and the double (for both banks of cylinders) VANOS variable camshaft timing has also been recalibrated, resulting in a peak engine output of 601bhp produced at 5500rpm, and peak torque of 590 lb ft arriving at 1550rpm, the curve remaining as flat as a pint of night club lager until 5500rpm.

The new - technology diesel engines operate quietly and efficiently by injecting the fuel into the cylinders at ungodly high pressures through teensy nozzles.

If the system is provided with an OT, well, it's pretty straight from here: a hotter vapour at a higher pressure reaches the compressor, and each piston inside each cylinder, in turn, has to pump that vapour through a small discharge valve on the head's reed plate: that is, the head pressure increases, the opposite force experienced by the piston during its movement increases and this results in more engine load.

To help with the explanation of the second component, Figure Two shows traces of in - cylinder pressure (black), port pressure at the intake valve (light blue) and port pressure at the exhaust valve (red), taken from a simulation of a high BMEP engine operating near the optimum tuning point for both intake and exhaust.

No other petrol engine features direct injection at a pressure of 200 bar, spray - guided combustion and piezo injectors, all in conjunction with map - controlled cylinder shut - off, an all - aluminium crankcase with «spectacle» honing, four - valve technology with continuous camshaft adjustment, a high compression ratio of 12.6: 1, a start / stop system and generator management — while revving to a maximum speed of over 7000 rpm.

In the case of the normally aspirated engine, at the start of the compression stroke the cylinder air / fuel volume is very high, this translates into a low starting pressure.

High Precision Injection in the new six - cylinder delivers fuel into the combustion chambers at a higher injection pressure of up to 200 bar over a wide range of running conditions.

With an intake pressure loss of just 25mb, a level rarely achieved on a production vehicle, cylinder filling is enhanced at medium and high speeds: • New dedicated air filter with a volume of 11.5 L (vs. 6.1 L) using an extra-high permeability filter cartridge.

Additional engine features: Iron cylinder block and aluminum DOHC cylinder head Forged steel crankshaft and connecting rods Oiling circuit that includes a dedicated feed for the turbocharger to provide increased pressure at the turbo and faster oil delivery Piston - cooling oil jets 16.5:1 compression ratio Common rail direct injection fuel system Ceramic glow plugs for shorter heat - up times and higher glow temperatures Balance shaft that contributes to smoothness and drives the oil pump Laminated steel oil pan with upper aluminum section that contributes to engine rigidity and quietness B20 bio-diesel capability The Duramax 2.8 L is the cleanest diesel truck engine ever produced by General Motors, and meets some of the toughest U.S. emissions standards, thanks in part to a cooled exhaust gas recirculation (EGR) system.

New TSI injectors can push fuel into the cylinder at a higher maximum pressure (250 bar or 3,626 psi), with up to three injection sequences per stroke depending on conditions.

The 4 valves per cylinder of the Double Over Head Camshaft layout ensures low pressure drop and super-efficient valve lift for a higher air filling; thus allowing the engine to make usable power at low end, mid-range and high - end rev bands.

Iron cylinder block and aluminum DOHC cylinder head Forged steel crankshaft and connecting rods Oiling circuit that includes a dedicated feed for the turbocharger to provide increased pressure at the turbo and faster oil delivery Piston - cooling oil jets 16.5:1 compression ratio Common rail direct injection fuel system Ceramic glow plugs for shorter heat - up times and higher glow temperatures Balance shaft that contributes to smoothness and drives the oil pump Laminated steel oil pan with upper aluminum section that contributes to engine rigidity and quietness B20 bio-diesel capability.

The engine features dual overhead camshafts with continuously variable valve timing and increased - authority cam phasing (increased phase rotation angle), a high - pressure returnless direct - injection fuel system with camshaft - driven fuel pump delivering 750 psi at idle and 2250 psi at full load, higher - flowing intake and exhaust ports in the cylinder head, electronic throttle control and pistons with jet - spray oil cooling.

The gas settles into a pressure gradient with higher pressure at the bottom and lower pressure at the top of the cylinder.

As the pressure is higher at the base there will be more gas to silver collisions than at the top of the cylinder where the pressure is lower.
