Sentences with phrase «intake rocker arm»

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.

However, each secondary intake rocker arm is shaped similar to a «Y» which allows it to contact two intake valves at once.

One primary intake rocker arm corresponds to each secondary intake rocker arm.

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

As a result of this design, there are only six primary intake rocker arms and six secondary intake rocker arms.

Moved by this pressurized oil, the pistons lock each cylinder's pair of intake rocker arms together.

Not exact matches

SVT modifications on the Mustang GT's 5.0 - liter block include GT - 40 style cylinder heads with special valves and roller rocker arms, a unique intake manifold, camshaft and exhaust among other things.

Or, to deactivate the valves and leave them closed, the pins are pushed in a direction that allow part of the intake and exhaust rocker arms to move with the camshaft and not move the closed valves.

Engine block and cylinder heads and all internally lubricated parts including pistons, piston rings, pins and cylinder sleeves; crankshaft, pulley, main bearings, caps and bolts; connecting rods, rod bearings, caps and bolts; camshaft (s), camshaft bearings, buttons and plugs; timing gears and timing chain or belt; rocker arms, rocker arm pivots, shafts and bushings; intake and exhaust valves, springs, guides, adjusters, retainers and seats; pushrods and lifters; intake manifold; exhaust manifolds; balance shaft; water pump; fuel pump; thermostat; oil pump, cover, gears, pressure relief valve and screen; rotor housing, rotors, shims and silent shaft; all internal fasteners, nuts and bolts; turbocharger / supercharger assembly including boost valve and wastegate; seals and gaskets.

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

By moving the pins, the intake valve rocker arms can follow one of two lobes on the camshaft (normal or high profile).

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 same occurs for the intake rocker shaft, except that the high - profile camshaft lobe operates the primary rocker arm.

This is because VTEC requires a third center rocker arm and cam lobe (for each intake and exhaust side), and, in the SOHC engine, the spark plugs are situated between the two exhaust rocker arms, leaving no room for the VTEC rocker arm.

The intake and exhaust rocker shafts contain primary and secondary intake and exhaust rocker arms, respectively.
