A transmission that changes forward gears automatically.
A device that converts heat energy into mechanical energy.
A system that provides fresh air to the exhaust system under controlled conditions to reduce emissions. The air source can be a pulse-air pump or an electrical or belt driven pump. Upstream air injection goes into the exhaust manifold to assist in after burning HC laden exhaust gases. Downstream air injection goes into the oxidation bed of the catalytic converter to help oxidize HC and CO emissions.
Connects the engine to the transmission and encloses the clutch assembly. It also provides mounting points for part of the clutch release mechanism.
