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.

Battery Runs Out
Jump-Starting
Jump-starting is dangerous if done incorrectly. So follow the procedure carefully.
If you feel unsure about jump-starting, we strongly recommend that you have a competent
service technician do the work.
