Sentences with phrase «rocker arms reduce»

• Two - lobe overhead cam and a pair of needle - roller rocker arms reduce friction by 50 percent for increased fuel efficiency and torque.

The use of aluminum in the pivot bearing and high tensile steels in the front axle bearing and in the transverse rocker arms reduces the unsprung inertial masses.

Not exact matches

Resin coating is applied to the pistons, and lightweight aluminum material is employed for the first time in a motorcycle in the friction - reducing roller rocker arm.

To reduce friction, the rocker arms have built - in rollers.

This design reduces valvetrain inertia more than is the case with an SOHC engine, since the rocker arms are reduced in size or eliminated.

Some SOHC multi-valve engines (such as the Mazda B8 - ME) use a single fork - shaped rocker arm to drive two valves (generally the exhaust valves) so that fewer cam lobes will be needed in order to reduce manufacturing costs.

Measures to reduce friction losses and thus help enhance engine efficiency include the adoption of narrow, lightweight roller rocker arms and low - friction timing chains, while D - 4S direct fuel injection helps create optimum combustion conditions, contributing to enhanced fuel efficiency.

The NR engine family (there's also a 1.5 L version in the Avanza) comes with intake and exhaust Dual VVT - i, teflon coating for the pistons (to reduce friction and improve durability), larger water jackets (better cooling, improved combustion, lower noise), roller rocker arm (reduces friction between rocker arm and camshaft) and iridium spark plugs (the 1.0 L KR in the Bezza and Axia also uses the latter).

In order to achieve the optimum volumetric efficiency in the lower portion of the engine's operating range, rocker arms are programmed to follow cam lobes that provide low lift and reduced duration (shorter time open with less valve lift).

Measures to reduce friction losses and thus improve engine efficiency include the adoption of narrow, lightweight roller rocker arms and low - friction timing chains, while D - 4S direct fuel injection helps create optimum combustion conditions, contributing to enhanced fuel economy.

Titanium valves, ultra — light weight rocker arms with a diamond — like coating and a fully integrated lower crankcase that reduces pumping losses at high RPMs combine to provide the driver with overwhelming acceleration right up to the 9,000 rpm redline.

The valve stems have been buffed and polished, the camshaft is lower friction and the weight of the rocker arms has been reduced.

Valve train Lightweight titanium intake valves are operated by roller rocker arms with integrated low rolling resistance needle bearings that significantly reduce friction between the cam and the sliding parts.
