Sentences with phrase «use rocker arm»

Unlike the other similar variable valve timing systems such as the Honda VTEC, the Toyota VVT - i and the Mitsubishi MIVEC which use rocker arm locking pins to change the valve timing, the CPS system uses direct - acting tappets with locking pins to change the valve timing and lift profile.

Now as I'm watching videos and reading more, it states that the camshaft go inside the cylinder block and use rocker arms etc to move the valves.

Not exact matches

I am so anxious to put this rocker to use cuddling my baby girl in my arms!

In most cases, the cam directly actuates the valve without the use of a rocker arm (it may or may not have a «lifter» between the cam and the valve).

OHV configurations use a centrally located cam shaft (central to the engine block), and actuates the valves through the use of lifters, pushrods, and rocker arms.

It uses a common rocker shaft for both the intake and exhaust rocker arms.

The J37A4 is able to use both intake and exhaust VTEC by use of a novel design of the intake rocker arm.

VTEC - E is the first version of VTEC to employ the use of roller rocker arms and because of that, it forgoes the need for having 3 intake lobes for actuating the two valves — two lobes for non-VTEC operation (one small and one medium - sized lobe) and one lobe for VTEC operation (the biggest lobe).

The multivalve Sprint version of the Triumph Slant - 4 engine used a system where the camshaft was placed directly over the inlet valves, with the same cams that opened the intake valves also directly opening the exhaust valves via rocker arms.

• LS3 / L92 Port Configuration • «As cast» runners and combustion chamber • 15 Degree valve angle • Assembled with 2.00» intake and 1.55» exhaust valves • 250cc intake port and 80cc exhaust port • 70cc combustion chamber • Intake flow — 280 cfm @.600» lift / Exhaust flow — 180 cfm @.700» lift • Beehive valve springs • Uses LS3 / L92 style rocker arms (offset) • 3.890» minimum bore size • Uses LS3 / L92 style intake manifold

For the engine, Folkestad chose to use custom aluminum heads from Automotive Machine Shop Services, a COMP Roller Cam with 4 - 7 firing order swap, an All American Billet front drive with ceramic coating, a single - plane intake manifold and scorpion shaft rocker arms.

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.

A 150 PS (110 kW) supercharged version of the smaller engine was added to the line - up in February 1987, [7][9] using the world's first needle roller rocker arm assembly.

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).

The 6G73 is a 24 - valve SOHC design with two valves running off a single cam lobe on the exhaust valves using a forked rocker arm and each intake valve actuated with two cam lobes, with a smaller bore than the 3.0 liter version of the same block.

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.

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.

Often the term «OHV» is used to describe the engine design where the camshaft is installed inside the engine block and valves are operated through lifters, pushrods and rocker arms.

The MDX's evolved 3.7 L V - 6 uses a more rigid cylinder block, high - strength crankshaft, heavy - duty connecting rods, high compression - ratio pistons, cylinder heads with improved cooling, exclusive camshaft specs, a new 2 - rocker arm design VTEC ® valvetrain system, more performance oriented camshaft specs when in VTEC ®, new intake valve springs, a new EGR system, unique long - reach spark plugs, a larger throttle body among other features.

The engine uses a more rigid cylinder block, high - strength crankshaft, heavy - duty connecting rods, high compression - ratio pistons, cylinder heads with improved cooling, exclusive camshaft specs, a 2 - rocker arm design VTEC valvetrain system, heavy - duty intake valve springs, a unique EGR system, special long - reach spark plugs, a large throttle body, and much more to get the job done.

Design features of the B and RB engines include 17 capscrews per cylinder head, a cylinder block that extends 3 in (76 mm) below the crankshaft centerline, an intake manifold not exposed to crankcase oil on the underside, stamped - steel shaft - mounted rocker arms (race versions used forged steel rockers), and a front - mounted external oil pump driven by the camshaft.
