Mazda CX-5 Service & Repair Manual: Mechanical
Outline
-
The sliding resistance*1 has been reduced by:
-
the adoption of a rocker arm (built into needle roller bearing)
-
reducing load on the valve spring
-
narrowing down the crankshaft journal
-
optimizing the piston skirt shape
-
adoption of a low-tension piston ring
-
lowered tensioning of the drive belt
-
A maintenance-free design for valve clearance has been achieved with the adoption of the HLA.
-
With the adoption of a piston cavity, cooling loss has been reduced.
-
The pumping loss*2 has been reduced with the adoption of the variable valve timing mechanism on both sides of the intake and exhaust.
-
The timing chain behavior has been stabilized and sliding resistance has been reduced by optimizing the shape and rigidity of the timing chain-related parts.
*2 Energy loss which occurs from each type of resistance corresponding to intake and exhaust is called pumping loss.

Hydraulic Variable Valve Timing Actuator
Purpose, Function
The hydraulic variable valve timing actuator operates according to the hydraulic
pressure and changes the phases of the exhaust camshaft. As a result, the open/close
per ...
Miller Cycle Engine
Outline
The Miller cycle engine is a high-efficiency engine which achieves high fuel
economy performance by obtaining a high-expansion ratio.
The Miller cycle engine achieves a high- ...
Other materials:
Tcs Off Switch, Tcs Off Indicator Light
Purpose/Function
The TCS OFF switch, located on the dashboard, allows for optionally enabling/disabling
the TCS control at driver discretion.
The TCS OFF indicator light, built into the instrument cluster, informs the
driver that TCS control has been disabled by operation ...
Clock Spring Adjustment [Two Step Deployment Control System]
1. Set the front wheels straight ahead.
CAUTION:
The clock spring will break if over?wound. Do not forcibly turn the clock
spring.
2. Turn the clock spring clockwise until it stops.
3. Turn the clock spring counterclockwise approx. 2 turns.
4. Align the mark on the clo ...
Instrumentation/Driver Info. Personalization
A personalization function has been adopted which enables the instrument
cluster settings to be changed.
The Mazda Modular Diagnostic System (M-MDS) is required to perform the setting.
Refer to the Workshop Manual for the detailed setting procedure.
