Sentences with phrase «pressure at low rpm»

We do not use it to produce power (it is operated by an electric motor) but to measure the pressure at low rpm (100 - 200).

The phrase «VTEC just kicked in yo» won't apply here — VTEC now solely controls the exhaust valves, reducing turbo lag through increased exhaust pressure at lower rpms while delivering a high output at higher engine speeds.

Not exact matches

The method works by sending exhaust air to the turbine through three smaller exhaust ports at low rpm, quickly creating boost pressure of up to 17.4 psi.

At higher RPM or under load, the pump would apply more force and you'll get more fuel through, but at lower pressures it won'At higher RPM or under load, the pump would apply more force and you'll get more fuel through, but at lower pressures it won'at lower pressures it won't.

That would explain it; at low engine RPM the oil pressure drops enough to turn on the light.

You want the turbo to spool up more quickly at low rpm for quick response, so the system sends engine exhaust to smaller ports to increase boost pressure.

PS - Using maths, the max pressure should be around 70 bars (theoretical, lower in reality) but I am getting around 20 bars (EDITED, previously 11 by mistake) at 100 rpm.

At the switch point a solenoid is actuated that allows oil pressure from a spool valve to operate a locking pin which binds the high RPM rocker arm to the low RPM ones.

It reduces back pressure at low engine rpm, improving throttle response.

Very low back pressure is one of the reasons why the power curve is still ascending at the 6,500 - rpm redline.

Whereas traditional VTEC operation changes valve opening duration based on higher oil pressure during high rpm operation at one side of the valvetrain's rocker arms, the Civic's i - VTEC system can switch valve timing duration at low rpm and low oil pressure using two hydraulic actuators on both sides of the intake rocker arm.

Special by - pass valves in the exhaust allow a quieter exhaust note at low speeds; at 4000 rpm these open to reduce the pressure in the exhaust system, raising the power output as well as generating a rousing aural accompaniment.

The system can route the exhaust gas heading to the turbo through smaller ports at a lower rpm to increase boost pressure and torque.

The pump is programmed to operate as needed, staying in low - pressure mode at rpms below 3,500, and then bumping up pressure as demand follows engine speed.

Rated at 188 horsepower at 5,600 RPM and 177 lb - ft of torque at 1,600 - 5,200 RPM, the 16 - valve DOHC aluminum - alloy inline 4 - cylinder engine includes a 10.5:1 compression ratio, Continuously Variable Valve Timing Control System (CVTCS), spray - coated and mirror - finish cylinder bores, a variable pressure oil pump and a low - pressure EGR system, which helps lower exhaust gas temperature and improve knock sensitivity.

The unique turbocharger is optimally matched to the 2.0 - liter EcoBoost engine and direct injection system, providing precise fuel pressure control to deliver boosted power at low rpm without annoying turbo lag.

Some of the key principles of Eco-Driving are: • Maintain engine speeds between 1200 — 3000 rotations per minute (RPM); • Change to higher gears between 2000 — 2500 RPM, and drive in top gears at lower speeds — the so - called «50 in 4th gear» driving style; • Try to anticipate more to avoid strong accelerations, decelerations, overtaking or aggressive driving; • Driving at speed limits and avoiding high speeds; • Add 10 % to standard tyre pressure; • Avoid using the air condition, or set at temperatures above 21Â °C; • Use your bike for short trips — starting your car when it is «cold» uses 300 % more fuel.»
