It also uses a smooth hydraulic
roller camshaft for excellent drivability and a broad performance range.
Not exact matches
Drive - E also emphasises a reduction of internal friction, including a redesigned and very rigid crankcase frame, and
roller bearings
for the twin overhead
camshafts.
Based on the value - driven 350 HO crate engine, our engineers swapped the flat - tappet
camshaft for a hydraulic
roller and added the latest Small - Block intake manifold design.
The Tau also has a rigid bed plate
for improved block rigidity and lower NVH (Noise, Vibration, and Harshness), as well as
camshaft carriers and a
roller timing chain to improve valvetrain stability.
1986 was a fairly major year
for Chrysler engines: both the 2.2 and 2.5 fours gained
roller camshaft followers,
for much better durability.
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).
It also has a bed plate
for improved block rigidity and lower NVH, as well as
camshaft carriers and a
roller timing chain to improve valvetrain stability.
* Dual overhead
camshafts (DOHC) and four valves per cylinder * Twin counter-rotating balance shafts
for operational smoothness * Electronic throttle control * Low - friction,
roller - finger follower valvetrain with hydraulic lash adjusters * Low - maintenance chain - drive
for the
camshafts * 58X crankshaft positioning * Direct - mount accessories, which reduce or eliminate traditional sources of noise and vibration * Full - circle transmission mount to reduce noise and vibration * GM Oil Life System, which can reduce the frequency
for oil changes * Innovative cast - in oil filter housing, which eliminates the need to crawl under the vehicle to perform oil changes and eliminates throwaway oil filter cans that retain used oil
It's said to feature new
roller - finger followers in the valvetrain; hollow
camshafts for weight reduction; redesigned valve - lash adjusters and new intake and exhaust valves
for better durability; both direct and port fuel injection; piston - cooling oil jets; a forged - steel, fully counterweighted crankshaft; and all - new turbochargers designed to delver more boost.

These include a highly - efficient intake port; an improved, variable intake manifold Acoustic Control Induction System (ACIS); a Tumble Control Valves (TCV) system; Dual VVT - i
for both intake and exhaust
camshafts; the adoption of
roller rocker arms; low tension piston rings; multi-point oil jets and a variable output oil pump.
