QG18DE
The 1.8 L (1,769 cc) QG18DE was designed for Nissan by Aichi Machine Industry, Japan. It is manufactured both in Japan and the Mexican city of Aguascalientes. Bore and stroke is 80 mm × 88 mm (3.15 in × 3.46 in). The engine is tuned to achieve most of its torque at low revs at the expense of raw power at high revs, making the engine very responsive in day-to-day driving. It has a cast-iron engine block, aluminum DOHC cylinder head, uses Multi-port fuel injection, forged-steel connecting rods, two single-piece cast camshafts and a cast-aluminum intake manifold. It also features N-VCT (Nissan's Valve Timing Control technology). This engine received the RJC Technology of The Year Award of 2001.[3]
Specifications
- Displacement - 1.8 L (1,769 cc)
- Layout - DOHC Inline-4 (Straight-4) with VVT tech (called NVTC).
- Valves - 16, 4 for each cylinder
- Power - 115 hp (86 kW) to 128 hp (95 kW) at 6000 rpm
- Torque - 122 lb⋅ft (165 N⋅m) to 130 lb⋅ft (176 N⋅m) at 2800 rpm
- Redline - 6500 rpm
- Fuel Delivery System - electronic fuel injection
- Fuel compression ratio - 9.5:1
Emissions Control Devices
- OBDII - On-board Diagnostic System (codes can be read/erased by a variety of readers, e.g. Actron blaZt). Nissan Pulsar N16 Models without EuroOBD in Australia do not have OBDII.
- EGR - Exhaust Gas Recirculation
- HO2S - (4) Oxygen Sensors (2 before exhaust catalyst, 2 after) - note a series 2 1.8l has only 2 O2 sensors: 1 pre-catalytic-converter and 1 downstream from it.
- TWC - Three Way Catalyst (2 in exhaust manifold, 1 under car).
- EVAP - Charcoal Evaporative Purge Canister.
- Ignition Timing: 9 degrees BTDC (can be altered +/- 2 degrees using CONSULT-II handheld diagnostic tester, e.g. blaZt).
- Knock Sensor - located on engine block; retards timing if pinging/detonation is detected.
- Heated Throttle Body - heated by engine coolant.
The QG18DE is used in the following vehicles:
- 2000-2006 Nissan Sentra B15 and N16
- 2000-2005 Nissan Pulsar N16
