2-Way Exhaust Control System
A 2-way exhaust control system is used on the TMMK made model. This system reduces the back pressure
by opening and closing a control valve that is enclosed in the main muffler, thus varying the exhaust gas
passage.
The control valve opens steplessly in accordance with the operating condition of the engine, thus enabling
a quieter operation at lower engine speeds, and reducing back pressure at higher engine speeds.
The basic operation is the same as that of the CAMRY SOLARA.
4. Fuel System
Fuel Injector
Along with the discontinuance of the air assist system on the California specification model, 12-hole fuel
injectors with highly atomized injection have been adopted.

CAMRY ± NEW FEATURES36
5S-FNE ENGINE
1. Description
The 5S-FNE engine is a new engine that uses CNG (Compressed Natural Gas) as fuel, which has been devel-
oped based on the 5S-FE gasoline engine.
The main component of natural gas is methane (CH
4), which has fewer carbous (C) than gasoline (mean mo-
lecular 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 exclu-
sively 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 equiva-
lent to the base engine. Moreover, this engine realizes extremely low emissions and restoring engine torque.
*: Already adopted on the California specification 5S-FE engine.

2. Features of 5S-FNE Engine
Features of the 5S-FNE engine are listed below.
Item
Features
Performance
High compression ratio is used.
High lift camshaft is used.
Low back pressure muffler is used.
Fuel Economy
High compression ratio is used.
Valve spring load has been reduced.
Low-friction. TiN (titanium nitride) coated valve lifters has been adopted.
Low Emission
A fuel injection system containing gas injectors has been adopted.
Because the fuel is in the gaseous state, it does not come in contact with
the wall surface, making optimal air-fuel ratio control possible
immediately after the engine has been started.
Precision air-fuel ratio feedback control that uses an air-fuel ratio sensor
and a heated oxygen sensor has been adopted.
Two catalytic converters designed exclusively for the natural gas engine
have been adopted: the WU-TWC (Warm Up Three-Way Catalytic
Converter) and the TWC (Three-Way Catalytic Converter).
Other Features
Highly rigid pistons have been adopted to accommodate the high
compression ratio.
A CNG (Compressed Natural Gas) pressure regulator that precisely
regulates the CNG has been adopted.
A large-bore delivery pipe and fuel hose with minimal internal conduit
resistance have been adopted.
The electro magnetic fuel shutoff valve is added on the delivery pipe.
A fuel pressure sensor that corrects the fuel injection volume and a fuel
temperature sensor have been provided on the delivery pipe.
The starting performance of the engine at low temperatures has been
ensured by increasing the volume of the airflow of the IAC (Idle Air
Control).
Materials that excel in wear resistance have been adopted on the valves
and valve seats for both the intake and exhaust.
Rust-resistant spark plugs have been adopted.
Aluminum lining and carbon fiber have been adopted in the fuel tank.
For the fuel gauge, a fuel tank fuel temperature sensor and a fuel pipe fuel
pressure sensor have been adopted.
