Engine

Liquid-cooled gasoline, 5-cylinder, in-line

engine. Aluminum alloy cylinder block with

cast-iron cylinder liners cast directly into the

block. Aluminum alloy cylinder head with

double overhead camshafts and separate intake

and outlet channels.
Engine lubrication is provided by an eccentric

pump driven from the crankshaft. Full-flow

type oil filter. Exhaust emission control is

accomplished by multiport fuel injection,

heated oxygen sensor(s) and three-way

catalytic converter.

Charge air cooler (Intercooler)

Turbocharged engines employ a

turbo-compressor to force air into the engine

inlet manifold and a charge air cooler to cool

the compressed inlet air. The resulting increase

in air flow raises pressure in the intake

manifold by approx. 8.7 psi (over atmospheric

pressure) and engine power output by approx.

50 horsepower over that developed by the

normally-aspirated engine. The charge air

cooler (which resembles a radiator) is located

between the turbo-compressor and inlet

manifold.
