OUTLINE OF NEW FEATURES
The Camry is a high-quality family sedan with advanced technology and sporty performance. The following
changes are made for the 1999 model year.
1. Model Line-Up
The following models have been added.
SXV20L-AEMDKK, SXV20L-AEPDKK
MCV20L-CEMNKA, MCV20L-AEPDKK
The following models have been discontinued.
SXV20L-CEMDKK, SXV20L-CEPDKK, SXV20L-CEMNKK, SXV20L-CEPNKK
MCV20L-CEMDKA, MCV20L-CEPDKK, MCV20L-CEPGKK
2. Engine
ORVR (On-board Refueling Vapor Recovery) system has been adopted on the 1MZ-FE engine models.
The basic construction and operation of this system are the same as in the '98 Camry with 5S-FE Engine.
The direction of the rotation of the radiator cooling fan of the 1MZ-FE engine models has been reversed.
A service port has been provided for inspecting the evaporative emission control system on all models.
For details, see the General 1999 Features section.
3. Axles
The rear axle bearing specifications have been partially changed.
4. Brakes
The brake specifications have been partially changed.
5. Body
The attachment method for the front bumper reinforcement has been changed.
The center pillar garnish extends into the vehicle's interior to provide its effectiveness in absorbing the
energy in case the occupant's head collides against the pillar.
A reinforcement has been added to the rocker panel to effectively dissipate the impact energy during a
frontal collision, thus minimizing the deformation of the cabin.
The front, center and rear pillar garnishes provide an impact-absorbing structure consisting of internal ribs
that dampen the impact.
6. Seat
A seat fabric has been changed on the CE grade models to improve the seat appearance.
7. Seat Belt
The shape of the tongue plate has been changed to help improve the usability of the seat belt.

INTRODUCTION
INTRODUCTION Ð OUTLINE OF NEW FEATURES3
OUTLINE OF NEW FEATURES
An engine that is based on the 5S-FE engine, yet uses natural gas, has been developed in order to reduce
exhaust emissions and the amount of CO
2 discharge. A model that uses this alternative fuel engine has been
added to the Camry lineup. The characteristics of the new model are listed below.
1. Exterior
A CNG (Compressed Natural Gas) mark is affixed to the luggage compartment door.
2. 5S-FNE Engine
Based on the 5S-FE gasoline engine, the 5S-FNE engine uses compressed natural gas. The fuel lines have
been designed exclusively for compressed natural gas application.
3. A140E Automatic Transaxle
The gear ratio of the differential has been changed to accommodate the performance of the 5S-FNE engine.
4. Brakes
Basically, the same brakes used on the 5S-FE engine model are used on the CNG model, except that the
size of the front brakes has been changed.
5. Suspension
To accommodate the weight increase of the rear section of the vehicle as a result of having the fuel tank
installed in the luggage compartment, the specification of the springs used in the rear suspension has been
changed to realize excellent riding comfort, stability, and controllability.
6. Tire
P205/65 R 15 tire is used.
7. Body

To install the fuel tank in the front area of the luggage compartment, the upper back panel has been
cut out.

A performance rod that joins the tops of the right and left rear suspension strut towers has been adopted.

The shape of the rear floor pan has been changed to prevent the luggage compartment capacity from
being reduced as a result of the installation of the fuel tank in the luggage compartment.
8. Seat
A fixed type seat back is used for the rear seat.
9. Seat Belt
2-point NR (Non-Retractor) seat belt is used for the rear center seat.
10. SRS Airbag
A signal that causes the supply of fuel to be cut off during a frontal collision is output by the airbag sensor
assembly to the ECM.

5S-FNE ENGINE
DESCRIPTION
The 5S-FNE engine is a new engine that uses CNG (Compressed Natural Gas) as fuel, which has been
developed based on the 5S-FE gasoline engine.
The main component of natural gas is methane (CH
4), which has fewer carbons (C) than gasoline (mean
molecular formula: C
7.5H13.4). Therefore, the amount of CO2 discharged by this engine is approximately
70% that of the gasoline engine. Furthermore, this engine achieves low-emission operation by precisely
controlled air-fuel ratio and using special catalysts for the CNG application.
However, because the fuel is in the gaseous form, its volumetric efficiency is low, causing lower power
output if this fuel is used in the base engine.
Therefore, the 5S-FNE engine has adopted the following features: a high compression ratio, the intake
valves with early closed timing, the intake and exhaust valves with increased lift, a low back pressure muffler
made possible by the 2-way exhaust system, injectors for gaseous fuel, and a catalytic converter designed
exclusively for CNG application. At the same time, precision air-fuel ratio control is effected through the
use of the air-fuel ratio sensor* and the heater oxygen sensor, thus achieving the level of performance that
is equivalent to the base engine. Moreover, this engine realizes extremely low emissions and restoring engine
torque.
*: Already adopted on the California specification 5S-FE engine.

NEW FEATURES Ð 5S-FNE ENGINE19
ENGINE CONTROL SYSTEM
1. General
An engine control system based on the 5S-FE engine has been adopted. The knock sensor has been discontin-
ued because natural gas has a high octane value and is less susceptible to knocking.
The engine control system of 5S-FNE and 5S-FE engines are compared below.
System
Outline5S-FNE5S-FE
SFI
Sequential
A D-type SFI system is used, which indirectly detects
intake air volume by manifold absolute pressure sensor.
Sequential
Multiport Fuel
Injection
The fuel injection system is a sequential multiport fuel
injection system.
Ignition timing is determined by the ECM based on sig-
nals from various sensors.
ESA

AdvanceThe ECM corrects the ignition timing in response to en-
gine knocking in accordance with the signals received
from the knock sensor.

Fuel Cut-Off
Control
The fuel shutoff valves for the fuel tank, fuel pressure
regulator, and delivery pipe are shut off to stop the sup-
ply of fuel when the ignition switch is turned OFF or
during abnormal conditions (such as engine stalling,
SRS airbag deployed, etc.).

Heater ControlMaintains the temperature of the oxygen sensor and air
fuel ratio sensor at an appropriate level to increase accu-
racy of detection of the oxygen concentration in the ex-
haust gas.

EGR Cut-Off
ControlCuts off EGR according to the engine condition to
maintain drivability of the vehicle and durability of the
EGR components.

Evaporative
Emission ControlThe ECM controls the purge flow of evaporative emis-
sions (HC) in the charcoal canister in accordance with
engine conditions.
Ð
Air Conditioning
Cut-Off ControlBy turning the air conditioning compressor ON or OFF
in accordance with the engine condition, drivability is
maintained.
*3*3
When the ECM detects a malfunction, the ECM diag-
noses and memorized the failed section.
DiagnosisThe diagnosis system includes a function that detects a
malfunction in the evaporative emission control sys-
tem.
Ð

or controls the engine according to the data already
stored in memory.

NEW FEATURES Ð BODY 6
BODY
DESCRIPTION
To install the fuel tank in the front area of the luggage compartment, the upper back panel has been
cut.
To prevent reducing the rigidity of the body due to the upper back panel that has been cut out, as well
as for installing the fuel tank, rear seat back, and package tray trim, a performance rod is used for joining
both rear suspension strut towers.
The luggage door support has been changed from the torsion bar to the damper stay type.
To prevent reducing the capacity of the luggage compartment due to the installation of the fuel tank
in the luggage compartment, the shape of the rear floor pan has been changed.
