1) Types of swirl
Swirl: One cylinder has two intake air ports, one is set horizontally and
the other one is set vertically. Swirl is the horizontal air flows in cylinder
due to the horizontal intake air ports.
Tumble: Tumble is the vertical air flows in cylinder due to the vertical
intake air port
Squish: Squish is the air flows due to the piston head. Normally, this is
appears at the final process of compression. In CRDi engine, the
piston head creates the bowl type squish.
2) Swirl control
In DI type diesel engine, the liquefied fuel is injected into the cylinder directly. If the fuel is evenly
distributed in short period, the combustion efficiency could be improved. To get this, there should be
good air flow in cylinder. In general, there are two intake ports, swirl port and tangential port, in each
cylinder. The swirl port generates the horizontal flow and the tangential port generates the longitudinal
flow. In low/mid load range, the tabgential port is closed to increase the horizontal flow. Fast flow
decreases the PM during combustion and increases the EGR ratio by better combustion efficiency.

c. Main Injection
The power of the vehicle is determined by the main fuel injection volume.
Main injection calculates the fuel volume based on pilot injection. The calculation uses the value for
accelerator pedal position, engine rpm, coolant temperature, intake air temperature, boost pressure,
boost temperature and atmospheric pressure etc.
d. Post Injection
Injection after main injection. Consists of After injection, Post 1, Post 2 injection.
Post injection reduces PM and smoke from exhaust gas. No actual output is generated during these
injections, instead, fuel is injected to the unburned gas after main injection to enable fuel activation. The
PM amount in the emission and smoke can be reduced through these processes.
Only up to 5 types of injections can be performed within 1 cycle. If these 7 injections are all performed,
fuel economy and emission performance becomes poor.

1. FUEL SYSTEM SPECIFICATION
Use Only Unleaded Fuel Rated at 89 Octane or Higher ▶
Fuel quality and additives contained in fuel have a significant effect on power output, drivability, and
life of the engine.
Fuel with too low an octane number can cause engine knock.
Caution: Use of fuel with an octane number lower than 89 may damage engine and exhaust
system.
To prevent accidental use of leaded fuel, the nozzles for leaded fuel are larger, and will not fit the
fuel filler neck of your vehicle. -
Do Not Use Methanol ▶
Fuels containing methanol (wood alcohol) should not be used in vehicle.
This type of fuel can reduce vehicle performance and damage components of the fuel system.
Use of methanol may damage the fuel system. -
Vehicle Fueling from Drums or Storage Containers ▶
For safety reasons (particularly when using noncommercial fueling systems) fuel containers, pumps
and hoses must be properly earthed.
Static electricity build up can occur under certain atmospheric and fuel flow conditions if unearthed
hoses, particularly plastic, are fitted to the fuel-dispensing pump.
It is therefore recommended that earthed pumps with integrally earthed hoses be used, and that
storage containers be properly earthed during all noncommercial fueling operations.

1. DESCRIPTION AND OPERATION
1) Exhaust System
When you are inspecting or replacing exhaust system components, make sure there is adequate
clearance from all points on the underbody to avoid possible
overheating of the floor panel and possible damage to the passenger compartment insulation and trim
materials.
Check the complete exhaust system and the nearby body areas and trunk lid for broken, damaged,
missing or mispositioned parts, open seams, holes, loose connections, or other deterioration which
could permit exhaust fumes to seep into the trunk may be an indication of a problem in one of these
areas. Any defects should be corrected immediately.
2) Catalytic Converter (Gasoline Engine)
When jacking or lifting the vehicle from the body side rails, be certain that the lift pads do not contact
the catalytic converter, as this could damage the catalytic converter.
Use of anything other than unleaded fuel will damage the catalyst in the catalytic converter. 1.

Catalytic Converter Structure ▶
The Catalytic converter of monolith type consists of 2
walled metal bodies which is made of Cordierite. The
principal element of converter consists of the materials
like Alumina or oxidized Serume in order to apply to
Ceramic Monolith. Washer coat operates first, and
catalytic metal elements (Pt, Pd, Rh) operates to
washer coat next.
Monolith type is lighter than other types, easy to
manufacture and quickly approaches to prope
r
temperature. Washer coat is used to make a contact
surface with exhaust gas bigger by adhering closely to
small holes
of inner layer. If a lead compound or phosphorus
adheres to the surface and the temperature rises, its
surface is decreased. The total area of general
monolith converter is about 45, 000~500,000ft3. (10
times of a football field) Generally Alumina (AL2 O3) is
used as a raw materialand its 7 phases of gamma,
delta, theta have big areas and high stability for the
temperature, and nowadays gamma Alumina is used
usually.
