Sentences with phrase «valve tappet»

Other engine highlights include a direct drive valvetrain that eliminates valve tappet clearance adjustment, and a direct - ignition system that places the ignition coils over the spark plugs, eliminating the need for a distributor and high - tension ignition wires.

Credit for this longevity goes to long - wearing iridium spark plugs, a long - life timing chain, and careful engineering of the precisely manufactured SOHC valvetrain - which reliably maintains proper valve tappet clearances until the first tune - up.

Credit for this longevity goes to long - wearing platinum - tipped spark plugs, a long - life timing chain, and careful engineering of the precisely manufactured DOHC valvetrain - which reliably maintains proper valve tappet clearances until the first tune - up.

In the valvetrain, roller swing arms and hydraulic lash adjusters reduce valve - driven friction to help improve fuel economy one percent compared with direct valve tappets.

Not exact matches

There are no intake or exhaust valves in a Wankel and hence no need for a camshaft or tappets to actuate them.
