FEATURES OF 1NZ-FXE ENGINE
The 1NZ-FXE engine has been able to achieve the following performance through the adoption of the items
listed below.
(1) High performance and fuel economy
(2) Low noise and vibration
(3) Lightweight and compact design
(4) Good serviceability
(5) Clean emission
Item
(1)(2)(3)(4)(5)1NZ-FE
The VVT-i system is used.
High-expansion Atkinson cycle has been adopted.
An offset crankshaft has been adopted.
A cylinder block made of aluminum has been adopted.
A stainless steel exhaust manifold is used for weight reduction.
A rearward exhaust layout has been adopted to realize the early
activation of the catalyst.
HC Adsorber and catalyst system has been adopted.
Fuel returnless system has been adopted.
12-hole type fuel injectors have been adopted.
The DIS (Direct Ignition System) makes ignition timing
adjustment unnecessary.
Quick connectors are used to connect the fuel hose with the
fuel pipes.
The oil filter is installed diagonally downward.
A timing chain has been adopted.
A vacuum system that detects leaks in the evaporative
emission control system has been adopted.
The vapor reducing fuel tank system has been adopted.
This system reduces the amount of fuel vapor that is generated.

LUBRICATION SYSTEM

The lubrication circuit is fully pressurized and all oil passes through an oil filter.

A trochoid gear type oil pump, which is driven directly by the crankshaft, has been provided in the front
of the cylinder block.

The oil filter has been installed diagonally downward from the side of the cylinder block to improve ser-
viceability.

AIR CONDITIONING
DESCRIPTION
The air conditioning system in the Prius has the following features:
Both heating and demisting performances are realized by adopting performances are realized by adopting
the 2-way flow heater type air conditioning unit.
A multi-tank, super-slim structure evaporator has been adopted.
An automatic air conditioning system which provides enhanced air conditioning comfort according to the
occupant's senses has been adopted.
A semi-center location air conditioning unit, in which the evaporator and heater core are placed in the ve-
hicle's longitudinal direction, has been adopted.
A compact, high-performance scroll compressor with oil separator has been adopted.
The heat exchange efficiency has been improved through the adoption of the sub-cool condenser.
This condenser is integrated with the radiator to minimize the space they occupy in the engine compart-
ment.
A compact, lightweight, and highly efficient straight flow (full-path flow) aluminium heater core has been
adopted.
This heater core is integrated with a PTC (Positive Temperature Coefficient) heater, which excels in heat-
ing performance.
PTC heaters have been provided in the air duct at the footwell outlet in front of the air conditioning unit.
However, air conditioning without the PTC heaters is offered as an option on the U.S.A. models.
An electrical water pump with a bypass valve that provides a stable heater performance even if the engine
is stopped due to a function of the THS (TOYOTA Hybrid System) has been adopted.
A clean air filter that excels in removing pollen and dust is standard equipment.

INSPECTION
HINT:
Inspect these items when the engine is cold.
1. INSPECT DRIVE BELT
(See page CO±4)
2. REPLACE SPARK PLUGS
(See page IG±1)
3. INSPECT AIR FILTER
(a) Visually check that the air filter is not excessively dirty or
oily.
HINT:
Oiliness may indicate a stuck PCV valve.
If necessary, replace the air cleaner element.
(b) Clean the air filter with compressed air.
First blow from the inside thoroughly, then blow off the
outside of the element.
4. REPLACE AIR FILTER
Replace the air filter with a new one.
5. REPLACE ENGINE OIL AND OIL FILTER
(See page LU±3)
6. REPLACE ENGINE COOLANT
(See page CO±2)
7. INSPECT CHARCOAL CANISTER
(Se page EC±7)
8. REPLACE GASKET IN FUEL TANK CAP
(See page SF±19)
9. INSPECT FUEL LINES AND CONNECTIONS
(See page SF±19)
10. INSPECT EXHAUST PIPES AND MOUNTINGS
(See page EC±13)
11. ADJUST VALVE CLEARANCE
(See page EM±5)
