Mazda CX-5 Service & Repair Manual: Exhaust Manifold
Purpose, Function
-
By lengthening the exhaust passage, the transmission of exhaust pressure waves to other cylinders can be delayed, and the amount of gas exhausted from a cylinder and forced back inside the combustion chamber is reduced By reducing the residual gas, the temperature inside the combustion chamber is reduced and the occurrence of knocking even at a high compression ratio is inhibited.
Construction
-
The exhaust manifold is installed to the rear of the engine. In addition, the catalytic converter (WU-TWC) is integrated (WU-TWC).
-
When the No.1 cylinder is at the intake stroke, the No.3 cylinder is at the exhaust stroke. By inducing the high temperature gas exhausted from the No.3 cylinder into the No.1 cylinder, the high temperature gas in the No.1 cylinder remains. If the amount of residual gas is high, the temperature in the combustion chamber rises and knocking can easily occur. With the 4-2-1 exhaust system, the transmission of exhaust pressure waves between each cylinder is delayed by the long exhaust pipes.
Exhaust System Removal/Installation
WARNING:
A hot engine and exhaust system can cause severe burns. Turn off the engine
and wait until they are cool before removing the exhaust system.

Tcs Control
Outline
The TCS control actuates torque reduction through engine control, as well
as using brake control to control traction.
NOTE:
Engine control: Engine output is lowered by fuel cut and ignition timing
control to reduce the traction, preventing driving wheel slip.

Cargo Compartment Light Bulb Removal/Installation
1. Disconnect the negative battery cable..
CAUTION:
Always disconnect the negative battery cable before performing the cargo
compartment light bulb removal. Otherwise, the circuit may be shorted resulting
in damage to the related parts such as the rear body control module (RBCM).
